How to Freeze Tomatoes

Did you know that you can freeze raw tomatoes with and without their skins? Tomatoes may be frozen raw or cooked, whole, sliced, chopped, or puréed. Tomatoes do not need to be blanched before freezing. Frozen tomatoes are best used in cooked foods such as soups, sauces and stews as they become mushy when they're thawed. To use the frozen tomatoes, remove them from the freezer a few at a time or all at once and then use them in any cooked-tomato recipe.

Season tomatoes right before serving rather than before freezing. Freezing may cause seasonings such as garlic, onion, and herbs to either strengthen or weaken. Choose one of the following methods to freeze raw tomatoes.
