Freezing Whole Tomatoes: A Step-by-Step Guide
This method is ideal for using tomatoes in cooked dishes where texture is not critical.
- Wash and Core: Rinse the tomatoes thoroughly and remove the core using a paring knife.
- Blanch (Optional): Blanching helps remove the skins easier after freezing. Drop tomatoes in boiling water for 30-60 seconds, then immediately transfer to an ice bath. The skins should slip off easily.
- Dry Thoroughly: Pat the tomatoes dry with paper towels.
- Freeze Individually: Arrange the tomatoes on a baking sheet lined with parchment paper, making sure they don’t touch.
- Flash Freeze: Freeze for 2-3 hours, or until solid.
- Transfer to Freezer Bags or Containers: Place the frozen tomatoes into freezer bags or airtight containers, removing as much air as possible.
- Label and Date: Clearly label the bags or containers with the date and contents.
Freezing Tomato Sauce: A Flavorful Option
Freezing tomato sauce is an excellent way to preserve a large batch of homemade sauce.
- Prepare the Sauce: Cook your tomato sauce according to your favorite recipe.
- Cool Completely: Allow the sauce to cool completely before freezing.
- Portion and Freeze: Pour the sauce into freezer-safe bags or containers, leaving some headspace for expansion.
- Label and Date: Label each container with the date and contents.
Freezing Diced Tomatoes: Ready-to-Use Goodness
Dicing tomatoes before freezing makes them convenient for adding to recipes.
- Wash, Core, and Dice: Wash and core the tomatoes, then dice them into desired size.

Common Mistakes and How to Avoid Them
- Not Removing Air: Air exposure leads to freezer burn. Use freezer bags specifically designed for food storage and press out as much air as possible. Vacuum sealing provides the best protection.
- Not Cooling Properly: Freezing warm or hot tomato sauce can raise the temperature in your freezer and potentially thaw other items.
- Using Inappropriate Containers: Avoid using glass containers for freezing liquids, as they can crack due to expansion. Opt for freezer-safe plastic containers or freezer bags.

Thawing Frozen Tomatoes
- Whole Tomatoes: Thaw in the refrigerator or under cold running water. The texture will be softer after thawing, so they are best used in cooked dishes.

- Diced Tomatoes: Thaw in the refrigerator or add directly to your recipe while still frozen.
Storage Time
Properly frozen tomatoes can last for 8-12 months in the freezer. For best quality, use them within this timeframe.
