10 Creative Ways to Use Leftover Tomato Paste (So Nothing Goes to Waste)

Tomato paste is a kitchen staple loved for its bold flavor and versatility. Because recipes often require only a small amount, it’s common to end up with leftover paste sitting in the fridge. Instead of letting it spoil, you can easily put it to good use in many delicious and practical ways.

Here’s how to make the most of every spoonful.

Why Tomato Paste Is So Versatile

Tomato paste is made from concentrated tomatoes that have been cooked down to create a thick, rich product. Its intense flavor adds depth, color, and umami to dishes without adding excess liquid. It can thicken sauces, balance sweetness, and enhance savory recipes, making it one of the most flexible ingredients in your kitchen.

How to Store Leftover Tomato Paste

To keep tomato paste fresh:

• Transfer leftovers from a can into an airtight container.

• Store in the refrigerator for up to one week.

• For longer storage, freeze it in small portions using an ice cube tray.

• Once frozen, move the cubes to a freezer bag for easy use later.

This method lets you grab only what you need without wasting the rest.

1. Boost Flavor in Soups and Stews

Adding a spoonful of tomato paste while sautéing onions and garlic helps deepen the flavor of soups and stews. Letting it cook briefly caramelizes the paste and enhances its richness.

2. Make Quick Pasta Sauce

Turn leftover paste into a simple pasta sauce by cooking it with olive oil, garlic, and herbs. Add a splash of wine, broth, or cream and simmer until thick. It’s fast, flavorful, and easy to customize.

3. Create Homemade Pizza Sauce

Tomato paste makes a great base for pizza sauce. Mix it with olive oil, garlic, oregano, and a pinch of sugar for a rich, tangy spread that’s perfect for homemade pizza.

4. Add Depth to Chili and Casseroles

Stir tomato paste into chili or casseroles during cooking. It enhances savory flavors and helps create a thicker, more satisfying texture.

5. Make Flavorful Marinades

Combine tomato paste with olive oil, vinegar, garlic, and spices to create a bold marinade. It works well for meats, poultry, and vegetables, adding both flavor and tenderness.

6. Upgrade Dips and Spreads

A small amount of tomato paste can transform dips. Mix it into hummus, cream cheese, or yogurt-based spreads to add color and a savory twist.

7. Prepare Homemade Condiments

Tomato paste is an excellent base for homemade sauces like ketchup or barbecue sauce. Simply blend it with vinegar, sweeteners, and spices to create a custom flavor.

8. Use It in Savory Baking

It may sound unusual, but tomato paste can add moisture and subtle flavor to savory baked goods. Try mixing a small amount into herb breads, muffins, or scones.

9. Enhance Rice and Grain Dishes

Stir a spoonful into rice, quinoa, or couscous while cooking. It adds color, depth, and a subtle tomato flavor that pairs well with many dishes.

10. Make Quick Cooking Sauces

Blend tomato paste with broth or water to create an instant sauce base for stir-fries, skillet meals, or braised dishes.
