Yes, you can freeze chopped tomatoes for later use, although their texture will change. They are best used in cooked dishes like sauces, soups, and stews after thawing.
Freezing tomatoes is a great way to preserve them, especially if you have a surplus from your garden or find a good deal at the store. However, the freezing process causes the water inside the tomatoes to expand and form ice crystals. When thawed, these ice crystals break down the cell walls of the tomato, resulting in a softer, mushier texture. This change in texture makes thawed tomatoes less suitable for fresh applications like salads or sandwiches.
Here's a step-by-step guide to freezing chopped tomatoes:
When you're ready to use the frozen tomatoes, simply thaw them in the refrigerator or use them directly from frozen in your recipe.
Consider roasting the tomatoes before freezing. Roasting intensifies their flavor and helps to remove some of the excess moisture, resulting in a better texture after thawing. Simply roast the chopped tomatoes with a little olive oil, salt, and pepper until softened, then cool completely before freezing.
