How To Store Tomatoes & Tomato Paste


If you have leftover tomatoes, especially if they are already cut, it’s important that you store them properly to keep them fresh and prevent spoilage. Here’s how to store your leftover tomatoes and tomato paste to keep them fresh and flavourful:

How to store tomato paste:

A half-used tube or can of tomato paste can be a lifesaver for future meals. Leftover tomato paste should be stored in an airtight container in the fridge. For long term storage, tomato paste can be portioned into an ice cube tray wrapped airtight in cling film and kept in the freezer.


You can then simply thaw a cube overnight in the fridge and stir it into soups, stews, or sauces for an instant hit of concentrated flavour!

How to store cut & sliced tomatoes:

If a tomato has been cut or sliced, it’s important to store it with the cut side protected. To do so, you should wrap the tomato in cling film and place it in the fridge with the cut side facing down on a plate. Cut tomatoes will have a shorter shelf life and so are likely to only stay good in the fridge for up to 3 days.

How to store whole tomatoes:

If your tomatoes have not already been in the fridge, they should be allowed to ripen at room temperature for the best flavour. Ideally, the tomatoes should be placed upside down a plate, a technique that will keep them good for longer by limiting air flow around the stem and reducing oxidation. If the tomatoes have already reached peak ripeness or were refrigerated previously, it’s best to put them in the fridge. They should be placed upside down on a plate separate from other vegetables and should store for up to a week.


Tomatoes should be allowed to reach room temperature again before being cooked or served.
