“My husband said it was the best pasta sauce I have ever made. The depth of flavor and simplicity was similar to what we experienced in Italy. It will be my go to recipe from now on.” – LuAnne
“By far the best sauce I’ve ever made. The soy sauce in the mushrooms adds a deep richness. You will never regret making this.” – Carolyn
“Absolutely love this recipe! 2nd time I’ve made it this summer, with the abundance of tomatoes my garden has produced. Thank You! This recipe is definitely a keeper.” – Cheryl
Why I Love This Sauce
I have been making homemade spaghetti sauce with fresh tomatoes for years, especially when our garden tomatoes are coming on faster than we can eat them. The flavor is so much fresher than sauce from a jar, and I love being able to adjust the texture and seasonings as it cooks.
The mushrooms give the sauce a hearty texture, and my little trick of adding soy sauce to the mushrooms brings out a rich, savory flavor without making the sauce taste like soy sauce. Fresh basil, oregano, garlic, and slowly simmered tomatoes finish it off. It takes a little longer than opening a jar, but most of that time is hands-off simmering, and the flavor is well worth it.
This sauce is also very flexible. You can keep it meatless, add ground beef or sausage, leave it chunky, blend it smooth, or roast the tomatoes first for even more concentrated flavor.

Ingredients You’ll Need

- Fresh tomatoes: Ripe garden tomatoes give this sauce its fresh flavor, but good-quality canned tomatoes will also work when tomatoes are not in season.
- Olive oil: Used to soften the onion and mushrooms and create the flavorful base of the sauce.
- Onion: A chopped yellow, white, or sweet onion adds a mild sweetness and savory flavor.
- Mushrooms: Fresh chopped mushrooms give the meatless sauce a hearty texture and rich flavor.
- Soy sauce: A small amount brings out the savory flavor of the mushrooms without making the finished sauce taste like soy sauce.
- Garlic: Freshly minced garlic adds the best flavor, but jarred minced garlic can be used when needed.
- Fresh herbs: Fresh basil and oregano give the sauce a bright, garden-fresh flavor.
- Brown sugar: Start with a small amount and add more only if the tomatoes taste especially acidic.
- Salt and pepper: Add these gradually and taste the sauce as it simmers.
Ingredient Additions and Substitutions
This fresh tomato spaghetti sauce is easy to adjust based on what you have in the garden or refrigerator.
- Bell peppers: Add chopped red, yellow, or green bell peppers with the onion.
- Carrots: Finely grated carrots add natural sweetness and help give the sauce more body.
- Zucchini: Stir in finely chopped zucchini for more vegetables and a chunkier sauce.
- Red pepper flakes: Add a pinch for a little heat.
- Red wine: Pour in a splash after sautéing the vegetables and let it simmer for a few minutes before adding the tomatoes.
- Tomato paste: Add one tablespoon at a time when you want a thicker or more concentrated sauce.
- Fresh parsley: Add chopped parsley with the basil or sprinkle it over the sauce before serving.
- Dried herbs: Substitute dried basil and oregano when fresh herbs are not available. Because dried herbs are more concentrated, use a smaller amount.
- No mushrooms: Leave them out or replace them with finely chopped bell peppers, carrots, or zucchini.
- Gluten-free option: Replace regular soy sauce with certified gluten-free tamari or gluten-free soy sauce.
- Vegetarian option: Keep the sauce as written and check that your soy sauce is vegetarian.
Make It a Meat Sauce
You can easily turn this into a hearty spaghetti meat sauce.
Brown about one pound of ground beef, ground pork, Italian sausage, ground turkey, or a mixture of meats. You can cook the meat with the onion or brown it separately and drain any extra grease before adding it to the sauce.
Continue with the recipe as written and let the meat simmer with the tomatoes and seasonings. The longer simmering time helps the meat flavor blend into the sauce.
You can also add cooked meatballs, shredded beef short ribs, or sliced Italian sausage. For another option, try our homemade meat sauce.
How to Make Spaghetti Sauce with Fresh Tomatoes

- Blanch the tomatoes. Cut a shallow X in the bottom of each tomato. Lower a few tomatoes at a time into boiling water and cook for 30 to 60 seconds, or until the skins begin to loosen. Transfer them immediately to a bowl of ice water.

- Peel and crush the tomatoes. Remove the skins and tough stem areas, then cut the tomatoes into quarters. Pulse them a few times in a food processor or blender until they look like crushed tomatoes. Do not completely purée them unless you want a smooth sauce.

- Cook the vegetables. Heat the olive oil in a large, heavy pot. Add the onion and cook until softened. Add the mushrooms and cook for a few more minutes. Stir in the soy sauce and garlic, then cook just until the garlic is fragrant.

- Add the tomatoes and seasonings. Stir in the crushed tomatoes, basil, oregano, brown sugar, salt, and pepper. Bring the mixture to a gentle simmer.

- Simmer the sauce. Cook uncovered for at least one hour, stirring occasionally and scraping the bottom of the pot. For a deeper flavor, simmer it longer. When simmering for more than two hours, cover the pot during the first hour, then uncover it so the sauce can reduce.

- Taste and serve. Taste the sauce and adjust the salt, pepper, sugar, or herbs as needed. Serve over hot pasta or use it in your favorite pasta recipe.
Best Tomatoes to Use
The best tomatoes for spaghetti sauce are ripe, flavorful tomatoes with plenty of flesh and not too much water.
- Roma or plum tomatoes are my first choice because they are meaty, have fewer seeds, and cook into a naturally thick sauce. Fresh San Marzano-style tomatoes are another good option when you can find them.
- Heirloom tomatoes add wonderful flavor, but some varieties contain more liquid. They may need a longer simmering time.
- Beefsteak tomatoes work well, especially when they are fully ripe, but they are usually juicier than Roma tomatoes. Combining them with paste tomatoes gives the sauce a good balance of flavor and texture.
- Cherry and grape tomatoes are naturally sweet and can be added to other tomato varieties. They are especially good when roasted first.
I often use a mixture of whatever ripe tomatoes are coming out of the garden. Tomato size and water content can vary quite a bit, so let the consistency of the sauce guide your cooking time.
For help growing your own tomatoes, take a look at our tips and tricks for growing tomatoes.
Roasting Fresh Tomatoes
Roasting the tomatoes first is optional, but it concentrates their flavor and brings out their natural sweetness. This is especially helpful when your tomatoes are juicy or a little less flavorful.
- Preheat the oven to 375 degrees F and line a large baking sheet with parchment paper.
- Cut the tomatoes in half. Scoop out some of the loose seeds and gel, then place the tomatoes cut-side down on the baking sheet.
- Roast until the skins blister and the edges begin to brown, about 30 to 45 minutes depending on the size and variety of the tomatoes.
- Pour any liquid from the baking sheet through a strainer and save it.
- Let the tomatoes cool enough to handle, then pull off the loosened skins.
- Add the roasted tomatoes and strained juices to the sauce pot and continue with the recipe.
Small cherry or grape tomatoes can be roasted with chopped onion, garlic, bell pepper, and a little olive oil. Their skins are thin enough that you can usually blend everything together without peeling them.
No Fresh Tomatoes? No Problem!
Home-grown tomatoes are delicious in this recipe but fresh, garden tomatoes can be hard to come by year-round. Whenever we can’t use fresh tomatoes, we always use DOP San Marzano Tomatoes. They are THE best alternative to homegrown tomatoes. We even use San Marzano tomatoes before resorting to store-bought tomatoes. For this recipe we use two 28oz. cans of tomatoes. We prefer using whole tomatoes as opposed to crushed tomatoes (most DOP tomato brands only come with whole tomatoes) and simply mash them with a potato masher as the sauce cooks down.
Recipe Tips
- Use a wide, heavy pot. A wider surface helps moisture evaporate so the sauce thickens more quickly.
- Choose very ripe tomatoes. Underripe tomatoes can make the sauce taste sour or flat.
- Do not overprocess the tomatoes. A few quick pulses will give you the texture of crushed tomatoes without turning them into juice.
- Cook the garlic briefly. Garlic can become bitter when burned, so add it after the onion and mushrooms have softened.
- Keep the heat low. The sauce should gently bubble rather than boil rapidly.
- Stir more often as the sauce thickens. Thick tomato sauce can stick and scorch on the bottom of the pot.
- Wait before adding all the sugar. Taste the tomatoes first, then begin with the smaller amount and add more only when needed.
- Salt gradually. Soy sauce already contains salt, so taste the sauce before adding the full amount.
- Blend for a smoother sauce. Use an immersion blender directly in the pot, or carefully blend part of the sauce and stir it back in.
- Add pasta water when serving. A small splash of starchy pasta water can help the sauce coat the noodles.
- Make a double batch. This sauce freezes well and makes an easy base for future pasta dinners, lasagna, and sandwiches.

Frequently Asked Questions
The soy sauce is added to the mushrooms rather than directly to the finished sauce. It brings out their deep, savory flavor, similar to the way I prepare sautéed mushrooms. The finished sauce should not taste like soy sauce. You can use low-sodium soy sauce, gluten-free tamari, or leave it out.
Simmer the sauce uncovered so excess water can evaporate. A wide pot will help it reduce more quickly. You can also add tomato paste one tablespoon at a time or blend part of the sauce with an immersion blender. Remember that the sauce will continue to thicken slightly as it cools.
Peeling the tomatoes gives the sauce a smoother texture, but it is not required. You can leave the skins on if you do not mind a more rustic texture. Blend the tomatoes well if you are keeping the skins.
No. I remove the rough stem area, but I do not usually remove all the seeds. You can scoop them out if you prefer a smoother sauce or if your tomatoes contain a lot of watery seed gel.
Yes. Sauté the onion, mushrooms, garlic, and soy sauce on the stovetop first. Transfer everything to a slow cooker and cook on LOW for 6 to 8 hours or HIGH for 3 to 4 hours. Leave the lid slightly cracked during the last hour if the sauce needs to thicken.
This particular recipe has not been tested for safe home canning, and it contains low-acid ingredients such as onions and mushrooms. Do not use it as a canning recipe. Use our tested canned spaghetti sauce recipe when you want shelf-stable sauce.
The final amount depends on how juicy the tomatoes are and how long you reduce the sauce. It generally makes about 5 to 7 cups, or approximately six 1-cup servings.
Yes. Fully ripe tomatoes may not need much added sugar. You can also add finely grated carrot with the onion for natural sweetness or add a splash of red wine. Taste the finished sauce before deciding whether it needs any sugar.
Yes. Granulated sugar will balance the acidity, but brown sugar adds a slightly deeper flavor. Begin with a small amount of either one and add more only as needed.
Marinara is usually a simpler tomato sauce made with tomatoes, garlic, herbs, and olive oil. Spaghetti sauce is a broader term and may include onions, mushrooms, vegetables, meat, or additional seasonings. This recipe is heartier than a basic marinara but can still be used anywhere you would normally use pasta sauce.
Yes. Add a splash of dry red wine after the onion and mushrooms have cooked. Let it simmer for two or three minutes before adding the tomatoes so the flavor has time to concentrate.
Troubleshooting
- The sauce is too thin: Continue simmering it uncovered. You can also add tomato paste one tablespoon at a time or blend some of the tomatoes into the sauce.
- The sauce is too thick: Stir in a small amount of water, broth, reserved tomato juice, or pasta cooking water until it reaches the consistency you like.
- The sauce tastes too acidic: Let it simmer longer, then add a small amount of brown sugar or finely grated carrot. Add only a little at a time and taste after each addition.
- The sauce is too sweet: Add more tomatoes, a pinch of salt, or a small splash of red wine or red wine vinegar to bring the flavors back into balance.
- The sauce tastes bland: It may need more salt, garlic, oregano, basil, or red pepper flakes. Tomatoes can vary greatly in flavor, so taste and adjust as the sauce cooks.
- The sauce is too salty: Add more unsalted tomatoes or a little water. Avoid adding more salt or soy sauce until the sauce has reduced.
- The sauce is sticking to the pot: Reduce the heat and stir more frequently. A heavy-bottomed pot will distribute the heat more evenly and help prevent scorching.
- The vegetables are too chunky: Blend the sauce with an immersion blender until it reaches the texture you want.

Make Ahead and Storage
This sauce is a great make-ahead recipe because the flavor gets even better after the ingredients have had time to sit together.
Allow the sauce to cool, then transfer it to an airtight container. Store it in the refrigerator for 3 to 4 days.
To freeze the sauce, cool it completely in the refrigerator first. Transfer it to freezer-safe containers, glass jars, or resealable freezer bags. Leave room at the top of rigid containers and jars because the sauce will expand as it freezes.
Freezer bags can be laid flat until frozen and then stacked to save space. The sauce can be frozen for up to six months, although the flavor and texture are best within the first three months.
Thaw frozen sauce overnight in the refrigerator. Reheat it in a saucepan over medium-low heat, stirring occasionally. Add a splash of water if it has become too thick.
Pairing Ideas
Serve this Homemade Spaghetti Sauce with Fresh Tomatoes over spaghetti with Olive Garden Salad, Loaded Cheesy Garlic Bread, or Oven Roasted Green Beans. You can also use it to make Meatball Sub Sandwiches or Chicken Parmesan Sandwiches.

Homemade Spaghetti Sauce with Fresh Tomatoes

Video
Ingredients
- 12-14 tomatoes, (fresh, garden tomatoes work best- appx. 6-8 lbs. You can also use two 28oz. cans of San Marzano tomatoes)
- 2 tablespoons olive oil
- 1 large onion, chopped
- 8 ounces mushrooms, fresh, chopped
- 2 teaspoons soy sauce, (see notes above)
- 6 cloves garlic, minced
- 10-12 basil leaves, chopped
- 1 tablespoon oregano, finely chopped
- 1-2 tablespoons brown sugar, (start with 1 tablespoon, taste, and add more as you go along as needed)
- 1 tablespoon Kosher salt, (or to taste)
- 1 teaspoon pepper, (or to taste)
Instructions
- Bring a large pot of water to a boil and prepare a large bowl of ice water. Cut a shallow X in the bottom of each tomato. Place a few tomatoes at a time in the boiling water for 30 to 60 seconds, or until the skins begin to loosen.

- Immediately transfer them to the ice water. Peel the tomatoes and remove the tough stem areas. Cut the tomatoes into quarters and place them in a food processor or blender. Pulse a few times until they reach the consistency of crushed tomatoes. Do not overprocess. Set aside.

- Heat the olive oil in a large, heavy pot over medium heat. Add the onion and sauté until softened and translucent. Add the mushrooms and cook for 2 to 3 minutes. Stir in the soy sauce and garlic and cook for another 30 to 60 seconds, or until the garlic is fragrant.

- Add the crushed tomatoes, basil, oregano, 1 tablespoon brown sugar, salt, and pepper. Stir well and bring the sauce to a gentle simmer.

- Simmer uncovered for at least one hour, stirring occasionally and scraping the bottom of the pot. Taste and add more brown sugar, salt, or pepper as needed. When simmering for two hours or longer, cover the pot during the first hour, then uncover it and continue cooking until the sauce reaches your preferred thickness.

- Taste once more and adjust the seasonings. Serve hot over cooked pasta or use in your favorite pasta dish.

Notes
- Tomato size, sweetness, and water content vary, so adjust the simmering time and seasonings as needed.
- For a chunky sauce, pulse the tomatoes only a few times and coarsely chop the vegetables.
- For a smooth sauce, blend the finished sauce with an immersion blender.
- If the sauce is too thin, simmer it uncovered longer or add tomato paste one tablespoon at a time.
- To make meat sauce, brown one pound of ground beef or sausage with the onion, drain any excess grease, and continue with the recipe.
- Two 28-ounce cans of whole or crushed tomatoes can be substituted for fresh tomatoes.
- For the slow cooker, sauté the vegetables first, then cook the sauce on LOW for 6 to 8 hours or HIGH for 3 to 4 hours.
- This recipe has not been tested for home canning. Use a tested canning recipe when making shelf-stable sauce.
- Refrigerate leftovers for 3 to 4 days or freeze in airtight containers for up to six months.

I’ve made this recipe multiple times, both with homegrown tomatoes and canned San Marzano tomatoes and it is *phenomenal*. Thank you for the tip on the mushrooms — I’ve been doing that ever since I made the first batch, and you’re absolutely right, it adds a definite ‘oomph’ to the umami of the ‘shrooms. Great way to use my garden herbs, too, and it freezes wonderfully. Nothing like enjoying summer tomato freshness in the middle of December!
Thank you for sharing!
Hey!! I left a comment a little earlier. Said the sauce was so thin. However, letting it cook longer to evaporate the juice from the tomatoes worked perfectly!! Love it! 55 years old and for the first time used some salad tomatoes that were getting soft for fresh sauce. Brilliant!!
Thank you for this simple base recipe!! #EAHWP
Love this sauce!
Any thoughts on adding meat?? if so, how and when? 🙂
Yes! Ground beef or sliced Italian sausage are some of our favorites. We cook it in a separate pan and add it right before serving.
I made this using fresh tomatoes during the summer but now we are into winter I must use canned tomatoes. My conversion chart indicates 1 pd of tomatoes = 14.5 oz diced canned tomatoes. Since I want to make the max of 10 lbs of fresh tomatoes, this would be 5 – 28oz cans of diced tomatoes. Is this correct? I question this because the recipe indicates it is for 6 servings which does not seem right.
We love this recipe! If you want a tasty sauce this is it. I believe the soy sauce is the secret ingredient. I do add an 1/8 tsp ground fennel. My husband suffers from acute pancreatitis and this doesn’t cause a flair up. I do cook the sauce longer then the recipe calls for. I simmer about an hour covered so tomatoes break down, then about 2 hours uncovered.
Flavor is great! As a first timer, easy to make..
This is the best spaghetti sauce recipe I have made and I was really happy to find a “big batch” recipe.
The only things I did a bit differently were to add 2 additional 12 oz cans of tomato paste (total of 24 oz), simmered for about 6 hours to get to my desired thickness, and I asded 2 packets of dry IGA brand spaghetti sauce seasoning just because I had gotten it for free and needed to use it so I threw it in.
Other than that I made it as is and it turned our perfect! Thank you!!
this is a great recipe. i love it just as is,,,,i didnt add anything else to it,,,love it thanks so much
This sauce was amazing! Very flavorful. I grow my own tomatoes and had a bumper crop this year. I have never made my own pasta sauce though. This was very easy to make. I just used a mix of different tomatoes (Rio Grande paste, Early Girl, Brandywine, Mountain Fresh and even a Yellow Boy). I followed the recipe to a “T” except for the garlic. I used garlic powder. Let it cook down for about 4 hours. My husband was blown away. I am going to make the puree and freeze it so I can do fresh sauce all winter. No idea how I will ever eat grocery store jarred sauce again. Thanks for this wonderful recipe!
Can this recipe be canned? I was worried about mushrooms. I use water bath.
This recipe has not been tested for canning but you can freeze it! Make a double batch of this glorious sauce and freeze it in a freezer safe Tupperware-type container, a large freezer-safe Ziploc bag or a glass jar. If you do go the glass jar route, make sure to leave an inch or two of space at the top of the jar so the sauce doesn’t expand and break. When freezing, make sure to cool the sauce completely in the fridge before freezing.The sauce will stay nice and fresh in the freezer for up to six months.
Ca this be frozen?
Absolutely!
This was my first time making this and its absolutely delicious
Having been raised by an Italian Mom and my Nana we always made pasta sauce from scratch. The best tomato to use (I’m growing then now) are San Marzana Tomatoes, 2nd best are Roma tomatoes. My wife and I make spaghetti alla Puttanesca (a dish to die for) the recipe calls for anchovies, capers, kalamata olives, garlic and tomatoes. You can look up the meaning, recipe and history of this authentic sauce. It takes as long as it takes to cook the pasta. I also make my own pastas, breads and so on.
This is all great information! Thank you for sharing with us. I am sure your bread and sauce is amazing!!
First time making Spaghetti Sauce using my homegrown tomatoes. My husband said it was the best sauce he ever ate and that we will no longer purchase store bought Spaghetti Sauce, and he meant it. Guess I better get to making more and freezing it. Thank you for a great recipe.
Wow! That is impressive! Way to go!! This homemade spaghetti sauce is so easy to make. Glad that you all loved it!
I made this with the suggested ‘roasting’ in the oven for the tomatoes. I loved it but the recipe was too sweet for husband and I so I’ll make it again w/o the sugar. I cooked it for 5 hours
Am trying this now with the roasted tomato option. Am wondering if I should cover the pot or not while it simmers. I’m using a cast iron pot.
Leave the pot uncovered. Hope you enjoy the sauce!
I love this recipe. I wanted to share a way to do mushrooms that also truly takes them to another level.
Dry cook them first. I truly mean throw them in a pan sliced your desired way completely dry. My friend learned this in Italy and it has taken every mushroom recipe I make now to an out of this world level. The texture and flavor I can’t put into words. When I make them people can’t keep their hands outa my pan so I tend to make extra. Add your soy sauce once cooked to draw out even more flavor or a little garlic salt. Add your sautéed onions separately to the sauce.
If you have never cooked mushrooms this way give it a shot. I promise you will not be disappointed.
Definitely will do it that way. Thank you
Real italians would never use sugar or soy sauce. Even mushrooms and onion are a matter of taste. When I make sauce (or gravy) I make it the italian way and people love it.
Soy sauce is just a different way of adding salt. Onions and basil provide sweetness, but there is nothing wrong with adding an extra pinch of sugar if needed. Mushrooms are internal of course, but add a lot of flavor.
My sister in law makes sauce “the Italian way” like her Italian grandmother. It is very simple, with almost nothing in it. She cooks it all day. It comes out perfectly smooth, with no texture or taste. There are no onions or visible herbs. I assume she adds garlic. But it is so bland.
Yet everyone raves about it! Why? Because it tastes amazing? No. They rave because they are expected to love what supposedly is “Grandma’s real Italian gravy”.
Who said this was supposed to be “Real Italian” It is one person’s recipe and you can like it or not. She calls it “Homemade Spaghetti Sauce.” Publish your own recipies. This was a great sauce as is.
With all respect, I don’t think anyone particularly cares what so-called ‘real Italians’ would or would not use. If you don’t approve of the recipe, don’t use it, but I really hate it when people just post on sites without having tried the recipe in any way and have nothing constructive to add.
From my perspective as a Southerner, I find it utterly ridiculous that people call spaghetti sauce ‘gravy’, anyway.
Well, not all of us are Italian, looking for that truly authentic Italian sauce. I, for one, am big on a sweet sauce and prefer to add sugar to it. We all like things differently.
OMG this is FANTASTIC ! My husband loved loved loved this recipe. He said and I agree best spaghetti sauce EVER ! This is my “wanna impress our friends who come for dinner recipe” and by the way that would be tomorrow, lol.
Saw some nice Roma maters on sale and mine are slowly coming in so what the ****- let’s make some sauce. I used forty or so leaves of fresh Basil from the back deck and double the recommendation of Oregano, also fresh picked. No mushrooms for us, diced three huge white onions finely and the flavor is amazing. I used an immersion blender. The sauce is thin but has boatloads of flavor. I’ll use this recipe after my garden harvest of Romas is done.
