How to Use Up Leftover Canned Tomato Paste
Whether you're making stew, a savory sauce for braising, or a classic Italian recipe, tomato paste is a great way to add a punch of concentrated tomato flavor and rich thickening action to your cooking, but most recipes call for a mere one or two tablespoons of the stuff. Assuming you're using the standard 6-ounce can, you'll want to use up the remaining 8 or 9 tablespoons before it goes bad in a few days. Here are a few helpful suggestions for how to avoid wasting it:
1. Freeze it
Unfortunately, once a can of tomato paste is opened--it will only laste in the fridge for 5 to 7 days. However, you can easily freeze tomato paste for 2-3 months simply by spooning the paste into ice cube trays. One completely frozen, transfer the individual cubes to a heavy-duty freezer bag. To use the cubes in the future, keep in mind that the cube sizes in a standard ice cube tray are approximately 1 ounce (or about two tablespoons).
**Note: Never store a can of opened tomato paste in the refrigerator or freezer. Instead, transfer your past to a glass or plastic container that's fully sealed.

2. Make tomato salt
Skip paprika and elevate dishes with a dust of tomato salt. You can keep this finishing salt up to two months in a sealed container and use it to add an instant flavor boost to dry rubs, salads, and appetizers. Try sprinkling it over your roasted vegetables, deviled eggs, and fresh salads to add a new layer of flavor. Did we mention all you need is two ingredients?
- 5 tablespoons unsalted tomato paste
- 1 1/2 tablespoons Maldon sea salt flakes
- Preheat oven to 225°F. Spread tomato paste in a thin, even layer on a baking sheet lined with a silicone baking mat. Bake 25 minutes or until paste is dry, slightly pliable in center, and brittle around the edges. Cool completely on mat; break into small pieces. Process tomato pieces into a fine powder using a spice grinder. Add sea salt flakes; pulse 3 to 4 times or until salt flakes are coarsely chopped. Store in an airtight container up to 2 months.
3. Make a big batch of tomato sauce
If you've got a nearly-full can of tomato paste that you need to use up quickly, try this recipe for making a pot of easy and flavorful homemade tomato sauce to use in pasta dishes, spoon over meat, dip snacks in, and more.
- 2 (28-ounce) cans diced tomatoes
- 1 (6-ounce) can tomato paste
- 1 cup water
- 1 teaspoon dried basil
- 1 1/2 teaspoons salt
- 1/4 teaspoon black pepper
- 1/8 teaspoon dried oregano
- 1/8 teaspoon red pepper
- Stir together first 8 ingredients in a large saucepan over medium-high heat. Reduce heat, and simmer, stirring occasionally, 40 minutes. Serve over pasta with Italian-style meatballs, if desired.
The tomato sauce should last about a week in the refrigerator, but it can last months in the freezer when stored in a securely plastic freezer bag. If you decide to freeze it, just be sure to allow the sauce plenty of time to defrost in the fridge before you plan to use it for your next pasta dinner.
