How to Store Tomato Paste?

You can use several methods to store your tomato paste. Whatever you used to store the tomato paste, always make sure that you store it in a cool and dry place. Tomato paste must not be kept near heat sources or sunlight. The best place to store your tomato paste is your pantry or kitchen cabinet. You can store them by sealing them with cling wrap or in a plastic bag with a rubber band.

Transferring the rest of the paste to an airtight container or a glass jar is also an ideal way to store your tomato paste. Note that every tomato paste has a “best by date” option. Do check that out before using it. Read on to find out some of the easy techniques for storing tomato paste.

Storing at Room Temperature

It is totally safe to store your tomato paste at room temperature. In an unopened can, away from sunlight, it can last up to 18 to 24 months, depending upon the quality of the paste you have bought.


It is always better to keep your tomato paste in the fridge once the container is opened. It offers a longer life in a fridge than if it is kept outside at room temperature. Once used, cover it properly and tightly to put it back in the fridge.


Tomato paste in cans must be handled with extra care rather than keeping it in glass jars or tubes. A tightly sealed, canned tomato paste can last up to five to seven days in your refrigerator, even after opening.

Glass jars

Tomato paste kept in glass jars has only a small shelf life of two days maximum.


Tomato paste bought in tubes has a longer shelf life as compared to the other two options. Tomato paste tubes, even after opening, can last up to 45 days. But remember that these are more expensive than others.
