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. 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.
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.

Homemade Canned Spaghetti Sauce
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
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. 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 (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 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.

Hi Erica, well it has been 2 weeks since I processed my spaghetti sauce and I just realized I didn’t out the lemon juice in – anything I can do to save it (lids are still sealed) or do I throw it out?
Thanks!
Hi Shelley, thanks for reaching out! Was this water-bath canned? Unfortunately, if lemon juice wasn’t added before processing in a water bath canner, the acidity may not be high enough to safely prevent bacterial growth. even if the jars are sealed. Since it’s been 2 weeks, the safest option is to throw the jars out. Reprocessing now wouldn’t make it safe because the sauce has already been sitting at room temperature without the necessary acidity. To do this safely, it would have needed to be done within 24 hours.
If you processed this with a pressure canner the batch is totally fine. The lemon juice isn’t required if pressure canning.
Thank you Erica, that’s what I thought too! At least it was only a small batch (1/4 of the recipe). The recipe is great – thanks!
Love this sauce. Third time making it. But had problem with bay leaves they must have broken up while cooking sauce and I couldn’t find them to discard. Hopefully won’t hurt anything.
Nah it won’t hurt anything. If they break up they usually break up into bigger pieces and they will be easy to spot when you re-heat or serve it. They aren’t toxic or anything, just unpleasant if you bite into one because they are just dry and tough.
Can you use coconut aminos for the same result as soy sauce. I’m trying to stay away from soy.?
I haven’t tested this recipe with coconut aminos before so I can’t say for sure. Your safest bet would probably be to just add a little more salt and leave it out the soy sauce completely. Hope this helps!
This is the best homemade pasta sauce recipe I have found!!! I made about 3 batches so far this year. I do add basil to my sauce and a little clear gel.
Wow thank you for the huge compliment and kind review!
Can you use fresh basil and oregano instead of dried?
It’s safest to stick with dried herbs when canning, since tested recipes are developed that way to ensure proper acidity. We haven’t tested this recipe with fresh herbs so I can’t say for sure. If you want to add fresh herbs, they can be added after opening the jar or when reheating for the best flavor and safety. Hope this helps!
How long after you open should it be eaten?
Once opened, home-canned spaghetti sauce should be refrigerated and used within 3–5 days. If you don’t think you will eat it that fast you can always freeze it for longer storage. Hope this helps!
Can you use a juicer/kitchenaid attachment vs boiling and skinning?
I’m not exactly sure. My mom will do this when canning tomato juice but she won’t use the attachment when she is doing spaghetti sauce. You still want to make sure you get the “meat” of the tomato so I don’t know if using a juicer will make it too runny/watery or if it will simmer down and still be ok. If you do try it, please let us know how it turns out!
Can I use pint size jars instead of quarts? If so, is it the same processing time in a water bath?
Yes, you can use pint jars. Processing times will be 5 minutes less. Hope this helps!
I am water bath canning my sauce. Do I add the lemon to each jar before I warm the jars prior to filling with sauce or after they are already warm?
You will want to add it after the jars are warm. I add the lemon juice immediately before adding the sauce to the jars. Hope this answers your question!
We made this recipe last year and making aagaon this year! Delicious sauce!
Thanks so much! Glad it has been a hit for you!
Can I safely reduce the amount of tomato paste to add?
Yes, you actually don’t need to add the paste at all if you feel like your sauce is thick enough. The paste is used as a thickener.
Please be careful with broken pieces of bay leaf. I almost choked on a small piece of it in my sauce!
Yikes! They are pretty nasty when bitten into and they can be sharp!
Can I use frozen tomato’s for this?
Yes, frozen tomatoes can be used for this recipe. 🙂
Love this recipe
Thanks! So glad you like it!
Can I can them in water bath instead of pressure cooker?
Yes, there are instructions above in the post for how to water bath can. Hope this helps!
I have been using this recipe for several batches. It is so good everyone loves it. Thank you for sharing.
You are welcome! So glad you liked it! It is our go-to as well.
Can you use fresh basil instead of dried? I have an abundance in the garden.
We haven’t used fresh herbs when testing this recipe for acidity. I know fresh herbs can raise the pH levels so I don’t know how it will affect the recipe. If you do use fresh herbs, you will need to do so at your own discretion. Hope this helps!
Absolutely I use fresh basil in mind all the time it gives it a better taste
Absolutely love this recipe!! 😍Hate when I loose it on Pinterest 😢 I have accidentally tried a couple others not near as good. Took pictures this time!! Need to print it ASAP
Delicious 😋 💕😍
Glad you were able to find it again! Definitely bookmark it if you need to!
Which variety of tomato do recommend, for the best tasting sauce?
That really depends. Really any red garden tomato will be a winner. I always have success with Romas but other garden varieties like Park’s Whopper, Celebrity, and Early Girls also work amazing. Hope this helps!
Best sauce ever, I use it in my rigatoni bake for potlucks, I received tons of compliments and requests for the recipe. My children do not want spaghetti unless I use this sauce “all of the other stuff tastes bad”
Your kids have good taste! I 100% agree, anything from the store just doesn’t taste right.
Can you just use green peppers? Also what kind of tomatoes do you use?
Yes, you can use green peppers. I just don’t prefer the taste as much. I like to use any garden variety: Romas, Celebrity, Early Girl, Park’s Whoppers… Etc… I have had success with all! Hope this helps!
