Canning Stewed Tomatoes
This page may contain affiliate links. More Information.
Canning stewed tomatoes gives you a versatile ingredient. I use this stewed tomatoes recipe as a base for stews. I use it in my chili. I will pour it over a roast in a Crockpot.
If you are canning stewed tomatoes, you will be adding peppers and onions. Celery is optional. Since you are adding other vegetable ingredients, botulism is a risk. This MUST be pressure canned.
Please note: I like this recipe because it has lots of veggies. It has only been tested as safe in a pressure canner. There are recipes available that are meant for a water bath, but this recipe is not one. Please don’t skip processing!
You will need to know how to use a pressure canner. This how to use a pressure canner page has more detailed information and step-by-step instructions.
This recipe makes approximately 7 pints. For my family, I almost always double this and do quarts.

Canning Stewed Tomatoes: Recipe with Extended, Step-By-Step Directions
Gather your canning supplies and ingredients.
Supplies:
- pressure canner
- canning jars
- canning lids and rings
- jar lifter and canning funnel
- large pot or blancher
- bowls
- large spoons
- sharp knife
- towels and dish cloths
Ingredients:
- You will need about 24 large tomatoes (enough to make 4 quarts peeled and chopped tomatoes)
- 1 cup chopped onion
- 3/4 cup chopped celery or green peppers
- 1 Tbsp sugar
- 2 tsp. canning salt
- Lemon juice (Ball’s canning recipe, my original source, doesn’t include lemon juice, but I’ve opted to include it for acidity per NCHFP safety recommendations.)
Note about the quantity: You’ll need 4 quarts of chopped, cored tomatoes. This cooks down a bit, so you should end up with around 3 quarts or 7 pints of stewed tomatoes when you are finished.
Peeling Tomatoes for Stewed Tomatoes
Start by preparing your jars and getting water in your canner heating. (See pressure canning for full directions.)
You’ll start by skinning (or peeling) your tomatoes.
Blanching tomatoes to remove skins is the easiest way for me. Use a blancher or a basket to dip your tomatoes, or you can just use a slotted spoon and a big pot of boiling water.
I have a Polder Stainless Steel Strainer and I love it! Highly recommended for all kinds of projects. Here is a link to it on Amazon: Polder Strainer
Depending on the size of the tomato, blanch 4 to 6 at a time. In these pictures I am working with Roma tomatoes. I like them for canning, because they are meatier than other tomatoes. They are smaller, so I can fit more in the strainer.
Wash tomatoes and dip in boiling water for 30-60 seconds or until you see the skins split. Start counting as soon as your tomatoes hit the water. Don’t wait for the water to come back to a boil to start your count time.
Quick Cleanup Tip
When I am canning stewed tomatoes or any other style of tomatoes, I love this super easy cleanup tip!
I have pots and containers set up in my double sink. The one on the left is for the cold water to cool the tomatoes as they come out of the hot water. The one on the right is to slide the skins off into. I slip the peeled tomatoes into a measuring bowl to measure how much I am getting done.
The work area is lower than if you set them on a counter. This make is easier on the arms and the sink makes for easy cleaning up later. Love that easy cleanup!
Home Canning Stewed Tomatoes
When you remove the tomatoes, drop them immediately into sink or bowl of cold water to stop the cooking. The skins should just slide off in your hands. Occasionally, I’ll use a knife on some stubborn spots. Slip off skins, and if you are working with larger tomatoes, quarter them. These are the smaller Romas, so I don’t bother cutting them up. They will mash up when I cook them.
Repeat steps until all tomatoes are skinned and chopped. You may need to let your water come back to heat in between batches in the blancher.
Chop your vegetables.
Remember, with a stewed tomatoes recipe like this, you can safely adjust the type of pepper you use.
Use a hotter variety for a spicy jar. Use bell or banana peppers for mild. Just don’t change the quantity or ratio of tomatoes to vegetables.
You can chop your vegetables either by hand, or chunk them up and place in a food processor! Love my food processor. The size of the pepper is not vital. You just want them chopped. If you use a processor, don’t overdo it! You can practically liquefy them. Don’t go that far. 🙂
Did you note the lack of pictures of onion chopping? That is because this day I had particularly potent onions and I was trying to just get them chopped as quickly as possible! No time for pictures because my eyes were tearing so badly. (sigh) What I do for my family. 🙂
Add your chopped onion and chopped bell pepper (or celery). Add the salt and sugar.
Simmer the tomato mixture 10 minutes. Stir frequently to avoid burning. At first, the mix will be chunky with pieces of tomato. By the time it is heated through, however, your tomatoes will be soft and saucy.
Pour hot stewed tomatoes into hot jars, leaving 1/2-inch headspace. Add lemon juice to each jar (1 Tablespoon per pint or 2 Tablespoons per quart.)
Wipe the rims clean, remove any air bubbles and place your lids.
Follow pressure canning instructions.

Canning Stewed Tomatoes Tips & FAQs
Stewed tomatoes in your pantry gives you a great base for lots of recipes. Use it to make Chili, soups, casseroles (or hot dish as we call it). Blend up the tomatoes after you open the jar and make tomato soup by adding a bit of basil, salt and pepper (half and half if you like it creamy!). It is just a great pantry item for many different things.
A stewed tomatoes recipe is a great way to spice up canned tomatoes. Remember it is a different recipe you’ll process it different than canned tomatoes. Add spicy peppers to heat thins up if you like it.
Celery in Home Canned Stewed Tomatoes?
“I noticed you don’t combine celery and bell peppers in your stewed tomatoes recipe. Wondered what the reason is. I would like to have both, and I’m just wondering if I can. Thanks, Sharon. I love your stuff, Sue.”
Notes from video:
The reason I leave the celery out when I am canning stewed tomatoes is…we just don’t prefer it. So I use all peppers and onions. You can certainly use celery too.
If you look at the recipe, in the ingredients list, I have celery or peppers. You want to use whatever combination of the two veggies, but use the same quantity. So you will have 1 and 3/4 cups of veggies total (onion, celery, or peppers).
If you want to do onions and peppers like we do, you’ll use the same amount of total cups of vegetables. I just don’t put the celery in there. I add more peppers or onions to make up the difference.
If you want to leave the peppers out, you could just do onions and celery. You’d use that same total number of cups. The recipe is good as it’s written. If you want to add celery, make sure to stay within the total number of cups per the amount of tomatoes that you have, so you stay within safe processing levels.

I accidently added twice as much of peppers, celery and onions. Did I ruin my batch of stewed tomatoes?
Unfortunately your batch is not processed properly. I would not consider it safe for storage on the shelf.
I’m a bit confused after
Reading the comments below , the recipe called for a processing time of 15 mins for pints and 20 mins for quarts .. Right?
Below a question from Craig about the time to process you had stated 25 mins is long enough .. I processed mine for 15 mins .. what should I do if anything .
Thank you Pamela
Hi Pamela, You are right, the processing time is 15 or 20 minutes as written. The 25 minutes Craig did was a little longer than needed but is just fine for safety. If you processed your pints for 15 minutes that is just fine. If you had quarts then it is under processed.
Hi, I am relatively new to canning ( only 5-6 years). My concern was based on some of my readings. From those readings, I was led to believe that when processing blended ingredients that the canning time would be for the ingredient with the longest processing time. As stated, the stewed tomato recipe is a ‘tried and true’ recipe. I am happy with the results.
I followed instruction as written and ended up with 8 pints .. it smells so good 😊 thank you for the easy step by step instructions Sharon.
I only hot 6 pints. But I believe I cooked it down a bit more. Bottom line, great recipe.
Hi, I just read your recipe and it sounds great. I can see the benefit of using stewed Tomatoes to pop a recipe up a notch. Personally, I like stewed tomatoes as a side dish aanyway.
I did have one question. Since onions require a longer canning time (40 minutes from what I have read), is canning at 25 minutes long enough? I have read that if canning with several items that it should be pressure canned at the longest time per the ingredients in the recipe.
Can’t wait to have enough tomatoes to try your recipe.
In the case of this recipe yes 25 minutes is long enough. It is a tested recipe with these specific ingredients. If you are mix and matching your own mix is where you need to be careful.
Thanks Sharon. I am doing my first batch this afternoon. This morning was 7 pints of dill pickles.
Hi Sharon, when canning stewed tomaotes, does the lemon juice flavor go away after processing? I don’t remember using it in 2020, and I didn”t can tomatoes last year. I had a bit left over, so I poured myself a glass, and added the lemon juice in the correct proportion. I did NOT like it! We use it for Bloody Marys. Also, do I need to put that much salt in it? Seems like a lot. Thanks in advance for your answer!
The salt is optional, so you can reduce that. But the lemon juice is needed as stated in the recipe. Personally I never taste it. You can also consider getting some Citric acid. It is sold where you can find canning supplies. Here is a link to some on Amazon. https://amzn.to/3RORt0K. I don’t think this will leave a taste either.
I stopped using salt in canning when I noticed that it was fermenting the contents of the jar.
Salt shouldn’t be fermenting the in the jars if you have processed them correctly. There might be something else going on. But leaving the salt out is fine.
How many Roma’s do I use to equal the larger tomatoes? I was gifted a boatload (11 grocery bags full) of Roma’s.
Great Question.The sizes of tomatoes vary so much. What might be large to me isn’t large to you. Even Roma Tomato size varies. So just be sure you have enough for “enough to make 4 quarts peeled and chopped tomatoes”. If you go by the quart amount it is much better than a number.
I don’t agree adding the lemon juice to the top after filling the jars since it will put your headspace off. I prefer to add it to the bottom, then when the hot filling is added, it can blend into the food instead of sitting on top. Otherwise, good recipe!
Yes adding it first is just fine. And good point about the headspace. You need to keep that in mind when you fill your jars. Leave some space there for the lemon juice.
I LOVE taking my canned stewed tomatoes (I use onion, celery & garlic) and put a couple tablespoons on a baking dish bottom. Put in stuffed shells and those frozen meatballs (Italian or homestyle is both good), spoon stewed tomatoes over each shell & the meatballs.. cover and bake according to the shell instructions. YUM!
Great, easy recipe. Will use again.
I’m sorry but I can’t find the chart for water bath canning. Is it missing or am I overlooking it?
Thanks for mentioning it! Because stewed tomatoes contain vegetables, they are only safe for pressure canning, NOT water bath canning. We’ve updated the recipe card so this is clear.

My Roma and heirloom tomatoes are not doing as well as my cherry tomatoes this year. Can I substitute cherry tomatoes for the others?
Yes, that would be fine.
-Rachel (Sharon’s assistant)
Canning stewed tomatoes looks just like what I want to do. Easy and versatile, and a food mill is not involved. Have a question though. You use Romas. I’ve always thought you should should the larger tomatoes for sauces and other tomatoes products and use Romas for chunky salsa. I thought the larger tomatoes had more flavor than Romas. Would love to hear your thoughts.
You can really use any type of tomatoes; it is just a preference of Sharon’s. 🙂 There is probably a flavor difference (it probably just depends on what you like!), but the main reason Sharon uses Romas is because they’re a “meatier” tomato. In her experience, they make a higher quality sauce product that isn’t so watery as other tomatoes might be.
