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.
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.
- pressure canner
- canning jars
- canning lids and rings
- jar lifter and canning funnel
- large pot or blancher
- large spoons
- sharp knife
- towels and dish cloths
- 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’m glad you’re not just adapting recipes without understanding what you’re doing, because that’s really important.
