How to Cook With, Store, and Substitute Tomatoes

From fresh summer heirlooms to hearty canned whole peeled plum tomatoes, tomatoes provide the bright acidity, rich color, and natural glutamates that turn simple skillet dishes into savory masterpieces.

How to Store Tomatoes for Maximum Freshness

Fresh ripe: 4 to 7 days

Room Temperature Countertop

Never refrigerate fresh whole tomatoes unless fully ripe and threatening to spoil. Cold damages enzyme activity and gives tomatoes a mealy, flavorless texture.

May slow moisture loss

Stem-Side Down

Store ripe tomatoes stem-side down on a flat surface, out of direct sun. The stem scar is where most moisture escapes, so covering it may help them stay firm a little longer.

Best Ways to Use Tomatoes

  • 20-minute burst cherry tomato and garlic pasta sauce with basil
  • Classic tomato and egg stir-fry (homestyle Chinese staple)
  • Rich shakshuka with poached eggs, cumin, and crusty bread
  • Fresh pico de gallo or rustic tomato bruschetta

Frequently Asked Questions

Are canned tomatoes as nutritious as fresh tomatoes?

In some ways. Heat processing makes lycopene, the red pigment in tomatoes, easier for the body to absorb, so canned and cooked tomatoes are a good source. Some vitamin C is lost in canning. Both are worth eating; canned tomatoes are often the more flavorful choice out of season.

How do I cut down acidity in tomato sauce without heaps of sugar?

Simmer the sauce longer, add a little fat such as butter or olive oil, or cook it with a halved onion (Marcella Hazan's well-known tomato sauce simmers tomatoes with butter and a halved onion). Some cooks also add a peeled carrot. A small pinch of sugar is a quick fix if needed.
