This canned spaghetti sauce is HANDS-DOWN, the very best with home-grown tomatoes. We are kind of crazy about our tomatoes over here. The taste of this savory tomato sauce stays fresh and turns any pasta dinner into something special.
Canning is the way to go when you want to preserve fresh produce. See our guides for canning fresh tomatoes, canning peaches and canning pears for more ways to enjoy homegrown fruits and vegetables all year long.
Ingredients in Canned Spaghetti Sauce
All you need for perfect spaghetti sauce are some herbs, spices and of course, fresh ripe tomatoes! This sauce couldn’t be simpler to make:
- Tomatoes – about 25 pounds. This recipe makes a huge batch of tomato puree.
- Onions – I start with about five large yellow onions. You’ll end up with 7-8 cups chopped onions.
- Red bell peppers – four large peppers work great.
- Green bell pepper – dice one large pepper
- Tomato paste – four 6-ounce cans should do the trick.
- Soy sauce – Sounds weird, but trust us, it deepens the tomato flavor like you won’t believe!
- Worcestershire sauce – stir in a little sauce to enhance the flavor of the tomatoes and give the sauce a meaty flavor.
- Brown sugar – a little sweetness balances the acidity of the tomatoes and all the herbs.
- Seasonings – Salt, garlic, oregano, basil, red pepper flakes, and bay leaves is all you need to season this delicious sauce.
- Lemon juice – for the jars
Why Can Spaghetti Sauce?
Canning spaghetti sauce offers several great benefits. It may take a little time up front but I love the satisfaction of walking into my pantry and seeing rows of freshly canned spaghetti sauce jars! Here are some more great benefits to canning:
- Long-term preservation: Enjoy homemade sauce even when fresh tomatoes are out of season.
- Control over ingredients: Customize the flavors, spices, and level of heat to suit personal taste preferences.
- Convenience and time-saving: Have ready-to-use sauce on hand for quick and easy meal preparations.
- Cost-effective: Save money by utilizing homegrown or bulk-purchased ingredients.
Tomatoes: A Family Tradition
Growing tomatoes is a “family tradition” of sorts for us. Our Uncle Larry is arguably the best gardener ever. He always has an immaculate garden and has studied and taught about gardening. The man knows ALL the tricks to get plants to grow. Uncle Larry has 10 green thumbs! His techniques have been passed around the family, luckily for us. He shared his secrets with our mom, who also grows a bountiful garden every year. To learn more about our tips and tricks for growing tomatoes, see our full guide for growing tomatoes.
Tomato growing is our family’s way to connect year after year. We compare notes on everything, from how our crops are faring, to what varieties we planted, to what has been canned so far. And of course, we love talking about all the delicious ways we can eat them! Along with the abundance of tomatoes comes a million ways to prepare them. One of our fondest memories growing up with our mom was making her delicious Homemade Canned Spaghetti Sauce. We’ve tweaked the recipe over the years and now it’s darn near perfection!
Family Tested, Dad Approved
Part of the reason we worked so hard to perfect this canned spaghetti sauce recipe is because of our dad. To know him is to know his passionate love for Italian food. He is super picky about spaghetti sauce; it has to be just right. Well, we’re happy to report that we served this sauce at family dinner recently and our dad loved it! He couldn’t get enough. In fact, he used a spoon to get all the excess off his plate. He’s crazy about this savory sauce, and you will be too!
How Can I Use Canned Spaghetti Sauce?
The name may say spaghetti, but this marinara sauce is so versatile, it’s sure to become one of your favorite staples, and not just on pasta night. Try it as a thickener for Italian-style soups like Minestrone, or add tomato paste to a serving to make pizza sauce. Here are some more delicious recipes that use spaghetti sauce:
Water Bath Canning Spaghetti Sauce
Water bath canning tomatoes is the most common way to can tomatoes, but it must be done the right way. Tomatoes are in the “gray area” of having enough acidity, so you need to add a bit of lemon juice or citric acid to ensure it reaches the correct acidity for canning. You can learn all about water bath canning in my water bath canning guide. If you want to learn about the basics of canning and other ways to can, check out my Canning 101 post as well. Between these two posts, you will learn how to be a water bath canning pro in no time!
How to Use a Pressure Canner
For a weighted-gauge pressure canner, you will want to process 20 minutes for pint jars and 25 minutes for quart jars. I like to use the Presto 16-Quart Pressure Canner, which is great for canning spaghetti sauce, homemade jams, and more. You can get it for $78 at Walmart to start canning your own sauces.
Process at 10 pounds for altitudes between 0-1,000 feet. Process at 15 pounds for altitudes above 1,000 feet. For more information on pressure canning spaghetti sauce, check out the National Center for Home Food Preservation here.
Where to Buy Canning Jars
We like to use 1-quart canning jars from Ball. They’re the BEST for canning spaghetti sauce. You can get 12 of them at Walmart for around $16, which makes it a little over $1 a jar and one of the more affordable ways to start canning. We also like to use them as drinking glasses, food storage, flower vases, and more, so you’ll get a ton of use out of them.
Frequently Asked Questions
Do not, I repeat, do NOT skip this step. Stick a reminder note on your jars or tie a ribbon on your finger so you don’t forget. You absolutely can not safely can tomatoes without bringing up the acidity first. If you forget to add the lemon juice you will need to open the jars, add the juice, replace with new lids, and reprocess.
You can add ground beef or ground Italian sausage ONLY if you are going to pressure can it OR if you freeze it instead of canning it (or you just want to eat it fresh or within a few days). Do not add ground beef if you are planning to water-bath can or steam can — it will not be safe to eat after sitting on the shelf.
Be really careful when adding or omitting ingredients to a canning recipe. You are usually fine adding spices but when it comes to adding fresh mushrooms, celery, parsley, thyme or meat it could throw off the acidity levels, thus making unsafe for canning.
We usually try to eat anything that we have canned within a year. You can probably go a couple years but probably not much longer than that. Some canning sites even say you shouldn’t go more than 6 months, but I think you are fine going longer than that.
Absolutely! This spaghetti sauce recipe freezes beautifully and lasts for several months in freezer bags or freezer-safe containers. Just make sure to thaw the sauce completely in the refrigerator before re-heating. If you DO want to add more random ingredients like ground beef or extra veggies, freezing is a good way to go if you are worried about acidity levels.
The only ingredient that has any gluten in this recipe is the soy sauce. It sounds weird to even have soy sauce in a spaghetti sauce recipe, but trust us, it is divine! Instead of cutting the soy sauce, opt for a gluten free brand. The rich flavor will knock your socks off!

- 25 pounds tomatoes
- 5 medium onions (about 7-8 cups chopped)
- 4 red bell peppers

- 3 tablespoons Worcestershire sauce
- 2/3 cup brown sugar packed
- 1/4 cup salt
- 10 cloves garlic chopped or minced
- 3 tablespoons oregano dried
- 3 tablespoons basil dried
- 2 teaspoons red pepper flakes
- 2 bay leaves

Instructions
- Fill a large pot or Dutch oven half-way with water, bring to a boil. Using a slotted spoon, add tomatoes one at a time until you can't fit any more (about 8-10 tomatoes).
- Boil for 1-2 minutes. Remove tomatoes one at a time with slotted spoon and plunge in an icewater bath. Peel and quarter tomatoes.
- In a food processor, cover and process green peppers and onions in batches until finely chopped (if you want to add extra flavor, saute the peppers and onions in a little oil and a pinch of salt before processing).In a large stockpot, combine the tomatoes (do not discard excess juices from the tomatoes), onion/pepper mixture, tomato paste, soy sauce, Worcestershire sauce, brown sugar, salt, garlic, oregano, basil, pepper flakes, and bay leaves.
- Bring to a boil. Reduce heat; simmer, uncovered, for 4-5 hours, stirring every 15 minutes or so (tomatoes burn easily so keep an eye on it). Discard bay leaves.If you want to make your sauce thick and smooth, use an immersion blender to blend the tomatoes until smooth with no large chunks (you can also blend it in batches in a blender).
- Add 2 tablespoons lemon juice to 9 or 10 hot 1-quart jars (depending on how much sauce you have). Ladle hot mixture into jars, leaving 1/2-in. headspace at the top. Remove air bubbles; wipe rims and adjust lids.

I’m eager to try this recipe! Quick question, can I leave the tomato skin on them and then blend it ? Or will that change the pH do you think?
Hi! To answer your question, no, leaving tomato skins on won’t alter the pH. I have never left them on and blended them before so I’m not sure if it will alter the texture much or not. If you try it, please come back and let me know how it turns out!
I got all 25 lbs of tomatoes from my garden. It cleaned it out good. Had to add some cherry tomatoes in to get to 25 lbs. I used onions, garlic from the garden as well and added a bit more garlic. I also used fresh herbs from garden (rosemary, basil and parsley) instead of the dried and went ahead and sauteed the onions and mostly shoshito peppers in the pan before blending. Took a while and didn’t realize it all wouldn’t fit in one pot. But I think it tastes delicious!
Josiah – your sauce sounds amazing! What a blessing to have such a beautiful and bounteous garden. I’m so glad this recipe worked for you. All of that work will be worth being able to enjoy delicious sauce for many months to come! Thank you for sharing this with us.
Wonder if I could simmer in the crock pot instead of the sauce pan. Less heat in the kitchen this time of year is best.
Yes you definitely can! A Crock Pot is a great idea!
I’d really like to make this sugar-free. Maybe using chopped carrots for a sweet note. Do you have any suggestions on what else can be used to replace the sugar? Thx.
Carrots could definitely help but we haven’t tested adding carrots to see how it affects the acidity. That may take some research. If you do want to make it sugar free, you will want to reduce the salt content as well, the two balance each other. My suggestion is to leave both out and then just add salt slowly until you get the flavor you want. Hope this helps!
Do you take all the seeds out after you peel and quarter the tomatoes?
No, I don’t bother removing the seeds but you definitely can if you would like!
First time canning sauce and this recipe is amazing! Won’t even try another recipe after this one. What would be the processing time for pint jars? Thank you
So glad you liked it! The processing time for pint jars is only 5 minutes less than quart jars for this recipe. You will still need to check your elevation to get the exact amount of time needed for processing. Hope this helps!
I have a question…instead of real sugar, can I use a sugar substitute like swerve?
I haven’t made it with a sugar substitute, I’m sure it would probably work but if you can I would stick to traditional sugar.
This is by far the best spaghetti sauce out there
The recipe is phenomenal! It’s a favorite of many i share it with. We all love that it has a little bite (heat) to it! The red pepper flakes i think are a perfect addition. I will Add that i don’t use a food processor, I like the larger chunks. i used to cut all of it by hand. I now use a hand chopper i dice it into quarters and take my aggression out on my new chopper (doesn’t work with frozen tomatoes)
For a few reasons I never blanch my tomatoes anymore. I freeze them. One, I don’t have enough plants to get enough at a time to make a batch. Two, when you take them out put in hot tap water (doesn’t need to be boiling, just as hot as your tap gets) leave for 30-60 seconds the skin will peel right off. You could maybe cut the stem part of before freezing. Three, when you go to cut the tomatoes they are usually still kinda frozen which makes it easier to cut if you use a sharp knife. They don’t fall apart into mush right away. This method saves me a ton of time!
Despite your warning, I did accidentally manage a very slight burn on the sauce, but it gave the sauce a “roasted tomato” flavour. The family loved it. In future I’ll try to avoid that burn, but I might add another hour to the prep time by purposefully roasting the veg ingredients. Thanks Erica. This recipe is in my keepers.
Oh dang, sorry you got a little burn but glad it didn’t taint the sauce at all! So glad you liked it, and you are very welcome! Thanks Martin!
