Tomato Paste vs Tomato Sauce: When to Use Each

If you’ve stood in the grocery store wondering whether tomato paste and tomato sauce (canned) are basically the same thing, you’re not alone. They look similar in a recipe but they’re not the same, and using one when you should use the other will change the dish. Here’s what I have learned cooking with both for years.

Quick Answer

Tomato paste deepens flavor. Tomato sauce is the cooked base. Both belong in your pantry. I open a tube of paste every other week; a can of sauce every week. Different roles, both essential.

What Is Tomato Paste?

Composition: Concentrated tomato puree, cooked down to ~28% solids, sold in 6oz cans or tubes

Best uses: Soup base, deepening pasta sauce flavor, adding umami to stews, the ‘first ingredient’ approach

Pros:

• Intense flavor in small amounts
• Adds deep color and richness
• Long shelf life

Cons:

• Not a stand-alone sauce
• Strong if used too much
• Needs to be cooked to taste right

What Is Tomato Sauce (canned)?

Composition: Tomato puree with some seasoning, ready to use, sold in 8-15oz cans

Best uses: Pasta sauce, pizza sauce, base for chili, Mexican rice, cooking down

Pros:

• Ready to use
• Versatile base for many dishes
• Cheap

Cons:

• Less intense than paste
• Some brands taste tinny
• Needs salt and seasoning

Can You Substitute One for the Other?

Using Tomato Sauce (canned) instead of Tomato Paste

For 1 cup tomato sauce, use 1 tablespoon paste + 7 oz water + pinch of salt + pinch of sugar.

Using Tomato Paste instead of Tomato Sauce (canned)

For 2 tablespoons paste, simmer 1/2 cup tomato sauce until reduced to 2 tablespoons. Takes 5-10 minutes.

My Honest Take

Tomato paste deepens flavor. Tomato sauce is the cooked base. Both belong in your pantry. I open a tube of paste every other week; a can of sauce every week. Different roles, both essential. Both have their place. Knowing the difference is what separates a frustrated cook from a confident one.
