Stewed Tomatoes
Stewed tomatoes are canned tomatoes that have been cooked down with diced celery, onion, green pepper, and a bit of sugar and seasoning before canning, giving them a softer texture and a rounder, slightly sweet flavor compared to plain diced or crushed tomatoes. They're already seasoned and partially broken down, which makes them a shortcut ingredient for soups, casseroles, and skillet dishes that would otherwise need extra aromatics cooked in separately.
Varieties
Some brands sell a Cajun or Southern-style stewed tomato with added celery seed and cayenne, which is spicier and more assertively seasoned than the standard version; check the label if a recipe calls for a mild base.
Buying tips
Check the ingredient list for actual diced onion, celery, and green pepper rather than just seasoning powder, which signals a better-quality product. Low-sodium versions exist and work well if you're controlling salt elsewhere in the recipe.
Substitutes
Diced tomatoes plus sautéed onion, celery, and green pepper — 1:1
Sauté 2 tablespoons each of minced onion, celery, and green pepper in a little oil until soft, then stir into 1 cup diced tomatoes with a pinch of sugar and simmer 5 minutes to soften.
Crushed tomatoes with Italian seasoning and a pinch of sugar — 1:1
Smoother and less chunky than real stewed tomatoes, but works fine in sauces and soups where texture matters less.
Fresh tomatoes, chopped and simmered with onion, celery, and green pepper — 1.25:1
Simmer chopped fresh tomatoes with the same minced vegetables and a pinch of sugar for 15-20 minutes until softened and reduced; fresh tomatoes lose volume as they cook down.
Tomato sauce blended with diced tomatoes — 1:1 combined
Mix equal parts tomato sauce and diced tomatoes to mimic the semi-broken-down texture of stewed tomatoes; add a pinch of sugar to match the sweetness.
Storage
Unopened cans keep for 1-2 years in a cool pantry. Once opened, transfer leftovers to an airtight container and refrigerate for up to 5 days, or freeze in a freezer bag for up to 3 months; the texture softens further after freezing but works fine in cooked dishes.
How to use
Add to soups, chili, and braises as both the liquid and the seasoning base, since the celery, onion, and pepper are already cooked in. Also good spooned over rice, mixed into casseroles like green bean or okra bakes, or simmered down further as a quick pasta sauce.
What it pairs with
Pairs well with ground beef or Italian sausage in skillet dishes, with rice and okra in Southern-style sides, and with white fish or chicken braised directly in the tomatoes.
Nutrition
A half-cup serving runs around 35-45 calories with roughly 2g fiber and a meaningful dose of vitamin C and lycopene; check labels since sodium varies widely by brand, and some add sugar beyond what's needed for flavor balance.
FAQ
What's the difference between stewed tomatoes and diced tomatoes?
Diced tomatoes are just tomato pieces in juice with no added vegetables. Stewed tomatoes include cooked-in onion, celery, and green pepper along with sugar and seasoning, giving them a softer texture and sweeter, more rounded flavor.
Can I use diced tomatoes if a recipe calls for stewed tomatoes?
Yes, but add a small amount of sautéed onion, celery, and green pepper plus a pinch of sugar to get closer to the intended flavor; plain diced tomatoes alone will taste flatter and more acidic.
Can stewed tomatoes be frozen?
Yes. Freeze in a sealed container or freezer bag for up to 3 months; the tomato pieces soften more after thawing, so they're best used in soups or sauces rather than dishes where texture matters.
Are stewed tomatoes already cooked, or do they need more cooking?
They're fully cooked during canning and safe to eat straight from the can, but most recipes simmer them further to blend flavors into the rest of the dish.
