Today we’re diving deep into the incredibly sexy world of canning tomatoes. The excitement is palpable!
Canning stewed tomatoes, aka canning crushed tomatoes, aka canning quartered tomatoes is a wonderful way to preserve the summer harvest with minimal work.
Minimal work is, of course, a relative term when it comes to canning. But this stewed tomatoes canning recipe is very straightforward.
If you love canning tomatoes (nerd), you should also check out Canning Tomatoes {Whole Tomatoes} and Canning Tomato Soup.
And if you’re ready to transition to canning fruit products (I know, I know, technically tomatoes are a fruit), try your hand at Canning Peaches, Canning Pears, and Canning Applesauce.
Before we get into the thick of it, it’s important to know that you can actually freeze these stewed tomatoes. If you just don’t feel like canning them when all is said and done, leave 1 inch of headspace and freeze in wide-mouth jars.
Canning Stewed Tomatoes Supplies & Ingredients
Check out this in-depth post for a complete list of canning supplies.
You’ll need:
- Tomatoes (obviously)
- Bottled lemon juice or citric acid
- Pressure Canner or water bath canner
- Large saucepan (I use my enameled dutch oven)
- Canning funnel
- Pint or quart canning jars (thrift stores are my favorite sources for these!)
- Jar lifter
- Ball Blue Book of Home Preserving
What kind of tomatoes work best for making stewed tomatoes? Whatever tomatoes you have! I would not use cherry or pear tomatoes simply because they are small and annoying to work with. Much like my two kids.
Roma and other paste tomatoes work really well because they aren’t very seedy and will cook down easily. If you have leftovers, check out this post on Freezing Tomatoes the Easy Way.
How Many Tomatoes Do You Need for Canning?
This stewed tomatoes canning recipe will fill 7 quarts of tomatoes. For 7 quarts you will need about 22 pounds of fresh tomatoes. It works out to about 3 pounds of tomatoes per quart.
If you are canning pints, you’ll need approximately 14 pounds for 9 pints. If you use 14-16 oz cans of crushed tomatoes from the store, a pint jar will replace one of those cans.
If purchasing tomatoes in bulk, a bushel weighs 53 pounds and will yield approximately 18-20 quarts of tomatoes.
Pro tip: if you grow your own tomatoes and don’t have enough to can at once (like me!), you can freeze them on baking trays and then transfer to freezer bags (I love these reusable silicone bags).
You can add the tomatoes to the boiling water without thawing them first. They will mush up so much you will not need to cut them ahead of time. :confetti:
WHY DO I NEED BOTTLED LEMON JUICE?
The lemon juice is needed to regulate the acidity of the tomatoes to keep the ph level consistent. Storebought lemon juice generally has the same level of acidity from bottle to bottle. You don’t get that guarantee with freshly squeezed lemons.
How Long Do You Process Stewed Tomatoes in a Water Bath?
Stewed tomatoes need to be boiled for 35 minutes for pints and 45 minutes for quarts.
Do You Have to Cook Tomatoes Before Canning?
No, you don’t have to cook tomatoes before canning them. That being said, canning raw (uncooked) tomatoes will result in what we call “fruit float”.
Fruit float means the uncooked or undercooked produce in the jars release additional liquids during the canning process. Your produce will float to the top of the jar and fill the bottom with liquid.
There is nothing wrong with fruit float as long as your jars are still sealed.
That being said, this stewed tomatoes canning recipe does require you to cook the tomatoes down prior to adding them to your canning jars.
How to Can Stewed Tomatoes
*water bath canning instructions are in the printable recipe card at the bottom of the post.
Pressure Canning Instructions
Rinse all your awesome tomatoes and cut in half and then quarters. If you have big ol’ hunkers, cut them into smaller chunks.
Prepare a large bowl with ice water.
Wash and clean your jars. It is no longer necessary to sterilize jars before canning (hurray!) but you should make sure they are preheated enough to not crack when placed in hot water.
You can put them in a clean dishwasher and run them through a quick wash cycle, or place them in a large pan with some water in a low heat oven (my lowest temp is 170 degrees) until you need them. I’ve even just put hot tap water in them before and left them on the counter.
Wash your lids with hot soapy water and place them in a clean bowl for now.
Add the tomatoes to a pot of boiling water and parboil them until you see the skins start to come off the tomatoes (about 1-2 minutes).
Use a slotted spoon and remove the tomatoes and place in the ice water.
Working with the tomatoes one at a time, remove any skin that hasn’t already slipped off.
Drain the pot you parboiled the tomatoes in, and add one-third of your skinned tomatoes to it. Cook over medium heat to maintain a gentle boil, stirring often.
Using a potato masher, gently crush the tomatoes to release juices. Add another one-third of the tomatoes, and gently crush those as well.
Add your final third of tomatoes, and maintain the pot at a low boil for 5 minutes. Stir often to prevent scorching. You do not need to crush these as having some intact tomatoes is fine and they will cook down even more in the canner.
Add 3 quarts of water to your pressure canner and put it on a burner set to high. Make sure there is a canning rack in the bottom of the canner.
Add lemon juice or citric acid to your canning jars (see recipe card below for exact measurements).
Using a canning funnel, ladle hot tomatoes in the jars. You really want to pack the tomatoes in there, so use a spoon to smoosh them down until they are covered in their own juices. Leave 1/2 inch headspace. Headspace is the distance between the top of the food and the top of the jar.
Using a long utensil (I prefer a plastic chopstick), remove all the air bubbles from the jar.
Clean the rim of the jar very well with a hot damp rag. Any juice or bits of tomato left on the rim may impact the seal of the lid in the canner.
Place a clean lid on the jar. Add a ring, and tighten to fingertip tight.
Place the jars in the canner. If you don’t have enough jars to fill the canner, consider Canning Water in a few jars to stock your emergency drinking water supplies.
Lock the lid. Soon, steam will start coming through the vent pipe (I call it the steam chimney). Allow the steam to pass through for about 10 minutes. Then put the pressure regulator (I call it the chimney cap) on top.
Pretty soon, the air vent will pop up. That is a sign that you’re starting to build pressure inside the canner (yay!). Stewed tomatoes need to be pressure canned at 11 pounds of pressure for 25 minutes for both pints and quarts.
When the dial gauge reaches 11 pounds of pressure, reduce the burner temp to medium, and start your timer. The pressure must stay at 11 or (a little bit) above for the duration of the cooking time. You’ll likely need to adjust the temp on the burner a few times depending on your stove.
When the time is up, remove the canner from the burner and allow it to sit until you hear a distinctive “click” of the air vent dropping. Remove the pressure regulator and carefully remove the lid (Pro tip: I always use oven mitts when I take the lid off because the steam is super hot).
Let the jars sit for 5 minutes in the canner and then lift them out with canning tongs. Place on a towel where they can sit undisturbed for 12 hours.
After a few hours, to check for sealing, gently press down in the middle of the lid. If the lid has no give, it’s sealed. If you can press the lid in and it pops a bit, your jars are not sealed.
You can reprocess them or store them in the fridge or freezer (only freeze jars that are wide mouth).
Can I add other vegetables to this Stewed Tomatoes Canning Recipe?
Adding anything not listed in the recipe means altering a safe and tested recipe.
If you want to add veggies to your canned stewed tomatoes, you need to follow a recipe from a trusted source like the one from The Ball Blue Book of Preserving (see recipe notes for tested ingredients).
Also, if you add low-acid vegetables to the mix, you must use a pressure canner to process your stewed tomatoes recipe.
How Long Do Canned Stewed Tomatoes Last?
Store in a cool dry place for up to 12 months.
How to Use Stewed Tomatoes
Stewed tomatoes are wonderful in homemade chili (related: Chipotle Instant Pot Turkey Chili or Butternut Squash Chili), vegetable soup (related: Instant Pot Vegetable Soup), or rice dishes (related: Leftover Turkey Casserole With Rice).

Love to see someone loving the canning as much as me. I’m in my own world in my kitchen canning tomatoes especially. It’s very relaxing and rewarding in the middle of winter opening a jar of your own canned. My canning started at the age of 9 with making jam from fresh picked strawberries. I’m 63 and doing even more than before. Love this site
Well…I don’t actually like canning. 🙂 But I like the results of it, so I keep doing it!
And you’re so right – opening a “fresh” jar of a summery food during a cold winter day is the BEST feeling.
