When it comes to cooking, tomato paste is a staple ingredient in many recipes. Whether you’re making pasta sauce, soups, or stews, tomato paste adds a rich, intense flavor that’s hard to replicate with fresh tomatoes. But have you ever wondered how long tomato paste lasts in the refrigerator? The answer may surprise you.
Understanding Tomato Paste
Tomato paste is made by cooking down fresh tomatoes to remove excess water and concentrate the flavor. This process creates a thick, spreadable paste that’s rich in nutrients and antioxidants. Tomato paste is often sold in jars or cans, and it’s a popular ingredient in many cuisines around the world.
The Shelf Life of Tomato Paste
The shelf life of tomato paste depends on several factors, including the type of tomato paste, the storage conditions, and the personal preferences of the cook. In general, tomato paste can last for several months to a year or more when stored properly in the refrigerator.
Unopened Tomato Paste
Unopened tomato paste can last for up to 12 months when stored in a cool, dry place. This is because the paste is sealed in a jar or can, which prevents air from entering and spoiling the product. When you open the jar or can, however, the paste is exposed to air, which can cause it to spoil more quickly.
Opened Tomato Paste
Opened tomato paste can last for several months when stored in the refrigerator. The exact shelf life will depend on the storage conditions, but as a general rule, you can expect the paste to last for:
| Storage Conditions | Shelf Life |
|---|---|
| Refrigerator at 40°F (4°C) | 3-6 months |
| Refrigerator at 50°F (10°C) | 2-4 months |
| Freezer at 0°F (-18°C) | 6-12 months |
Signs of Spoilage
Tomato paste can spoil if it’s not stored properly or if it’s past its expiration date. Here are some signs of spoilage to look out for:
- Off smell or taste
- Mold or yeast growth
- Slime or mold on the surface
- Changes in color or texture
How to Store Tomato Paste
To extend the shelf life of tomato paste, it’s important to store it properly. Here are some tips:
Refrigeration
When storing tomato paste in the refrigerator, make sure to:
- Transfer the paste to an airtight container
- Label the container with the date and contents
- Store the container in the refrigerator at 40°F (4°C) or below

- Store the container or bag in the freezer at 0°F (-18°C) or below
Recap
In summary, tomato paste can last for several months to a year or more when stored properly in the refrigerator. The exact shelf life will depend on the type of tomato paste, the storage conditions, and the personal preferences of the cook. When storing tomato paste, make sure to transfer it to an airtight container, label it with the date and contents, and store it in the refrigerator at 40°F (4°C) or below. If you won’t be using the paste within a few months, consider freezing it to extend its shelf life.
Frequently Asked Questions
Q: Can I use tomato paste that’s past its expiration date?
A: While it’s generally safe to use tomato paste that’s past its expiration date, the quality and flavor may be compromised. If the paste has an off smell or taste, it’s best to err on the side of caution and discard it.
Q: Can I store tomato paste at room temperature?
A: No, it’s not recommended to store tomato paste at room temperature. Tomato paste is a high-moisture product that can spoil quickly if it’s not stored in a cool, dry place. Refrigeration or freezing is the best way to extend its shelf life.
Q: Can I use tomato paste that’s been frozen?

A: Yes, you can make your own tomato paste at home. Simply cook down fresh tomatoes with some oil and seasonings until they reach the desired consistency. This can be a fun and cost-effective way to make your own tomato paste, but keep in mind that homemade tomato paste may not have the same shelf life as store-bought varieties.
