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. Garden tomatoes work best. I have used Roma, Celebrity, Early Girl, Park’s Whopper, San Marzano, and Beefsteak with success. I have even thrown in handfuls of cherry tomatoes when I have excess!
- 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. I just use the bottled lemon juice from the store.
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!
A Quick Note About Acidity Levels in This Recipe
We’ve tested this recipe for safe water bath canning nine times, exactly as written, and it has always been in the safe range. A pH of 4.6 or lower is considered safe for canning, and this recipe consistently comes in between 3.7 and 4.2. We have used Roma tomatoes, Celebrity, Park’s Whopper, and other red garden varieties with success. Acidity can vary between tomato types and the soils they are grown in so you still should always can at your own discretion and follow the Home Food Preservation Guidelines.
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 at Walmart to start canning your own sauces.
Process at 11 pounds pressure up to 2,000 feet elevation, increasing by 1 pound for every 2,000 feet (12 lbs for 2,001–4,000 ft, 13 lbs for 4,001–6,000 ft, and 14 lbs for 6,001–8,000 ft). For more information on pressure canning spaghetti sauce, check out the National Center for Home Food Preservation website.
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 if you are water bath or steam canning. Stick a reminder note on your jars or tie a ribbon on your finger so you don’t forget. You absolutely can not safely water bath or steam can tomatoes without bringing up the acidity first (this isn’t necessary for pressure canning). If you forget to add the lemon juice you will need to open the jars, add the juice, replace with new lids, and reprocess.
Fresh garden tomatoes are always the best choice. I’ve had great results with Roma, Celebrity, Early Girl, Park’s Whopper, San Marzano, and Beefsteak varieties. And when I have extras, I even toss in a handful of cherry tomatoes!
The number of tomatoes in 25 pounds really depends on the variety and size of the tomatoes. If you’re using smaller varieties like Roma or plum tomatoes, you’ll get about 70–80 tomatoes in 25 pounds. For medium-sized tomatoes, it’s closer to 55–65, and for large beefsteak tomatoes, you can expect around 35–40. So in general, 25 pounds of tomatoes will give you somewhere between 35 and 80 tomatoes, depending on the size.
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. When it comes to canning it’s best to stick with a tried and tested recipe and don’t deviate.
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!
I always peel the tomatoes and remove the rough stem area but they don’t need to be seeded. If you prefer to remove the seeds you certainly can. If you decide to leave the skins on, it won’t change the acidity but it will change the texture.
If you can get it to all fit, sure! Just simmer in the Crock Pot with the lid off until it reaches your desired thickness.
Yes, please adjust the sugar and salt to your personal liking. It will not affect the acidity so taste as you go and adjust in small amounts.
The amount of jars this recipe yields really depends on the water content of the tomatoes and how long you reduce the sauce. You can get more or less than what the recipe says depending on how thick you make it.
The easiest way is to just let it simmer until it thickens. You can also add tomato paste to thicken if needed.
If you like it more chunky, you can just roughly chop the tomatoes and veggies instead of blending.
YES. You can use ½ teaspoon of citric acid instead of lemon juice. Citric acid is more concentrated so you will need less. I like using lemon juice because it’s cheaper and more accessible but either one works.
If pressure canning. Yes! 1 tablespoon of fresh herbs = 1 teaspoon dried herbs. However, this recipe has not been tested for water bath canning with fresh herbs so we can’t say how it will affect the pH levels and we can’t recommend it.
We weigh our tomatoes before peeling.

Ingredients
- 25 pounds tomatoes, (Any garden variety. I have used Roma, Celebrity, Whopper, Early Girl, Beefsteak, San Marzano, and even handfuls of cherry tomatoes)
- 5 medium onions, (about 7-8 cups chopped)
- 4 red bell peppers
- 1 green bell pepper
- 4 (6oz) cans tomato paste
- 1/4 cups soy sauce, Sounds weird, but trust us, it deepens the tomato flavor like you won’t believe!
- 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
- 1 1/4 cups lemon juice, for jars (this is only needed for water bath and steam canning, if you are pressure canning this can be left out)
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. Do this over a large bowl so it catches all the juices when you slice them, you want to keep all those juices for the sauce. Note: I get a LOT of questions about if the tomatoes need to be peeled and seeded. I always peel the tomatoes and remove the rough stem area but they don’t need to be seeded. If you prefer to remove the seeds you certainly can though. If you decide to leave the skins on, it won’t change the acidity but it will change the texture and appearance.
- In a food processor, cover and process 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, 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 each jar. This typically yields 8 to 10 hot 1-quart jars (depending on how much sauce you have and how much it is reduced when simmering). If using pint jars, use 1 tablespoon of lemon juice per jar.Ladle hot mixture into jars, leaving 1/2-in. headspace at the top. Remove air bubbles; wipe rims and adjust lids. Do not forget the lemon juice! If you forget to add the lemon juice you will need to open the jars, add the juice, replace with new lids, and reprocess.
For Water Bath Canning:
- Process for 40 minutes in a boiling-water canner for altitudes of 1,000 feet or less. For altitudes up to 3,000 feet, add 5 minutes; 6,000 feet, add 10 minutes; 8,000 feet, add 15 minutes; 10,000 feet, add 20 minutes.
For Pressure Canning:
- Using a weighted-gauge pressure canner, process 20 minutes for pint jars and 25 minutes for quart jars. Use 11 pounds pressure up to 2,000 feet elevation, increasing by 1 pound for every 2,000 feet (12 lbs for 2,001–4,000 ft, 13 lbs for 4,001–6,000 ft, and 14 lbs for 6,001–8,000 ft).
Notes
- This recipe makes 9-10 quart-sized jars. This can be more or less depending on how much the tomatoes simmer down and thicken.

Love this recipe?
We want to hear from you! Please leave a review.
What is the shelf life for this spaghetti sauce once canned thru the water bath process? I don’t think I saw that anywhere on the recipe. Excited to try the recipe ????
Typically in canning forums they it is best within a year but we have gone 2-3 years and it has been fine 🙂
if I used fresh oregano do I have to freeze it? thanks
I don’t think you would need to freeze it– just add at least 5x the amount so you get the same flavor. Hope this helps!
made this yesterday. we are some tonight. ” best sauce you ever made” from my husband. did not change a thing on the recipe
So glad that you (and your husband) liked it! 😀
Hi. Am curious as to why if they are growing tomatoes with less acidity,why can with lemon juice,wouldn’t it make more sense to grow the tomatoes they were instead of creating a problem for people who home can.I have been canning for 40+years,never had any problems.no I didn’t add citric acid nor lemon juice to any of my sauces,juices,soup,ketchup all which were made using roma an beefy tomatoes.
Simmering now and it smells delish! It seems to be reducing nicely after 2 hours — will it continue to reduce (and get thicker) after more time?
Yes, it will keep reducing the longer you have it on. Hope you like it!
Well..how was it?
I looked and looked and looked for a spaghetti sauce recipe i thought would be worth my time trying to make. I have been so excited to try this recipe and we finally have enough tomatoes to try it! We are getting ready to make it and I will be posting back with how it goes and our opinions of it!
I am excited to hear how you like it! Be sure to come back and let us know!
Ah, I found this again! Last year I made this recipe and canned it, gave it to coworkers and everyone raved about it. Sadly, I did not bookmark the site, so I feared that I had lost it! It’s time to make some more sauce today, and absolutely LOVE this recipe! Thanks for posting it for me to find (and again a second time).
So glad you liked this recipe!!! It is a favorite of ours, too! Actually getting ready to make a batch this week– we can’t get enough!
After the 25 lbs of tomatoes are skinned and seeded, how many quarts or litres will there be ? Mine are already at that point.
It should make anywhere between 7-10 quarts (we usually get about 9)
I am interested in making this. I am new to canning and was wondering if I could add carrots, zucchini and olives to it? I love texture in my sauce!
You need to be careful when adding veggies when canning because it can throw off the PH-balance. I don’t know for sure what those veggies would do to the balance but if I were you I would add them when you are preparing your meal AFTER you have already canned, but that is just me. I would saute the carrots, zucchini, and olives and then pour the sauce over and heat before serving. Hope this helps!
Sounds really good! Do you get rid of all the tomato seeds or just blend them up too? Thanks!
We just blend them up– it makes it easier 🙂 Hope this helps!
Thanks the recipe. I looked around for a good pasta sauce that could be canned – either pressure or hot water. I followed the recipe exactly. I did not saute the onions and peppers (since some folks think this is controversial). The sauce took about 5 hours to reduce. I was hoping this was as good as the sauce I made last year. Well, gotta say, this recipe knocked it out of the ball park. It is nice, thick, spicy, delish! Some small children might like it due to the pepper flakes. I didn’t know what kind of onions to use – so I used a couple varieties. I love my salsa thick, rich and flavorful, and this recipe delivers. I yielded 9 quarts. Thanks for sharing.
Patty- Thank you so much for your comment! I am so glad that you like it! Thank you for sharing how many quarts you yielded. 🙂
Is it necessary to use lemon juice if freezing the sauce? Or is that just for canning?
Thank you.
just for canning– you won’t need to add if freezing.
Is this supposed to be spicy…I followed it exactly…seems spicy
Sounds like it would make great chili….spaghetti sauce, not so much.
It is delicious! It sounds strange but the flavors work!
Delicious! I’ve been canning tomatoes for some time, but spaghetti sauce was a first for me. I have a huge basil plant and so I used fresh basil, about two cups. (We really like our basil.) Otherwise followed the recipe exactly. Thanks!
So glad you liked it! We would definitely use fresh basil if we had that much readily available– great idea!
If not canning and making a smaller portion can you make this in a crockpot? If so how would you do that?
Yes, you can– you would want to probably do 1/4 to 1/5 of the recipe and just put it in the crock pot.. depending on the size of your crock pot.
Sorry haven’t tried your sauce yet. Just did my own and am commenting for those asking about pressure canning. I process @ 11# for 20 min for quarts, 15 min for pints. Have not had a problem in 40 years of canning. My sauce has mushrooms in it also just an FYI. Your sauce looks wonderful, think I will try it next time, enjoy trying new things!
I’m going to try this recipe because we like a sweeter sauce and this looks like it might be but I’d be interested in your recipe too. It’s always good to try a couple different recipes to see whats the best fit for the family 🙂 I prefer using a pressure cooker to water bath so your recipe would be great.
Hi!!
I’ve made your sauce one other time and it was awesome! I remember last time I made it, I was a little confused with the processing instructions.
Your instructions say:
“Process for 40 minutes in a boiling-water canner.”
Just to be *crystal* clear, you mean to submerge the jars in boiling water (cover by 1inch) and then boil for 40 mins… Right?
I may just be having a brain fart, but I cannot remember what I did last time I made this sauce!! I *think* I processed it in a pressure canner, but I cannot remember how long or at what pressure.
Can you clarify? This recipe is definitely a keeper!! It’s going into the Family Bible (what we call my Grandmother’s cookbook).
Thanks!
Yes, you are right. You will want to use an actually water-bath canner (I am assuming that is what you have). You can do it in a pressure canner but since I don’t have one myself, I don’t know what times and pressure to recommend. I hope I was able to answer your question! So glad you like the recipe! It is a favorite around here, too!
I already diced my tomatoes from the garden and froze them in a bag. I would now like to can them and use this recipe. I have 22 pounds that I have diced up already and kept the juice also. I saw that if you use a canned diced tomato, you should add sauce. Do you think I should add sauce, or is the juice enough? I am hoping 22 pounds is enough, considering I already skinned them and cut out the cores. Do you think 22 pounds with sauce will work?
I mean 22 pounds with *natural juice, not sauce. Will the juice alone and 22pounds work. Sorry.
I’m not exactly sure how well it will go from frozen to canned. You probably would want to add at least a little sauce so it isn’t runny. Maybe simmer it down and see what you think? Hope this helps!
Also how does adding the lemon juice to the bottom of the jar effect the acidity of the food? Thanks again
Cassandra
It raises the acidity to a safe level for canning. Hope this helps!
Just made this last Sunday. Tastes great but one question. Why process so long? Mine was a great consistency after 2 hrs and seems to have thickened more over the last week. Thanks
Cassandra
The processing time is for safety for canning. As far as the simmering goes, if you like the consistency after just 2 hours you won’t need to simmer any longer! If you are happy with it– great!
