How to Freeze Tomatoes for Long Term Storage Easily

Last Updated on October 22, 2026 by D. Ruddy

If your garden is overflowing with ripe tomatoes or you found a great deal at the market, freeze tomatoes to preserve their fresh flavor for months. Freezing is one of the simplest ways to save tomatoes for sauces, soups, and stews without losing their rich taste. This guide covers everything you need to know to freeze tomatoes properly, from prep work to storage tips.

You can freeze tomatoes whole, sliced, or as puree by blanching them first to remove skins. Frozen tomatoes last 8-12 months and work best in cooked dishes where texture isn’t critical.

Why Freezing Tomatoes Works Better Than Other Methods

Freezing tomatoes locks in their peak flavor and nutrients without the fuss of canning. Unlike drying, which concentrates flavors but changes texture, frozen tomatoes retain their natural juiciness when thawed. This method is ideal for home gardeners or anyone with a surplus of tomatoes that need preserving quickly.

• Preserves nutrients better than canning, which can degrade some vitamins
• No special equipment needed—just a freezer and basic kitchen tools
• Fast and easy with minimal prep time compared to other preservation methods
• Versatile for use in sauces, soups, and stews
• Cost-effective way to save money by buying in bulk or using garden harvests

According to the National Center for Home Food Preservation, freezing is one of the safest methods for preserving tomatoes at home, as it inhibits bacterial growth without the need for pressure canning.

Best Tomato Varieties for Freezing

Not all tomatoes freeze equally well. While you can freeze any type, some varieties hold up better in texture and flavor after thawing.

Roma and San Marzano tomatoes are the top choices for freezing because of their low water content and meaty texture. Cherry tomatoes are great for adding whole to dishes, while beefsteak tomatoes work best when used in cooked recipes where their texture isn’t a primary concern.

Tip: Avoid freezing tomatoes with thick skins like some heirloom varieties unless you plan to remove the skins first through blanching.

Step by Step Guide to Freeze Tomatoes Properly

Follow this simple process to freeze tomatoes while maintaining the best quality. Each step ensures your tomatoes stay fresh and flavorful for months.

Step 1: Select and Wash Tomatoes

Pick firm, ripe tomatoes without bruises or blemishes. Underripe tomatoes may develop off-flavors when frozen, while overripe ones can turn mushy. Wash them thoroughly under cold running water to remove any dirt, pesticides, or bacteria.

Pat them dry with a clean towel.

Step 2: Prepare Tomatoes for Freezing

Decide how you’ll use the tomatoes later to determine the prep method. For whole tomatoes, leave them as-is. For easier use in recipes, you can slice, dice, or crush them.

If you prefer skinless tomatoes, blanch them first.

1. Whole tomatoes: Freeze as-is for later use in sauces or soups
2. Sliced or diced: Cut into uniform pieces for quick addition to dishes
3. Crushed: Mash tomatoes for immediate use in sauces
4. Juice or puree: Blend tomatoes for a smooth base

Step 3: Blanching (Optional but Recommended)

Blanching helps remove skins and kills enzymes that can affect flavor and texture. To blanch, bring a pot of water to a boil. Prepare an ice bath in a large bowl.

Cut a small “X” on the bottom of each tomato. Submerge tomatoes in boiling water for 30-60 seconds, then immediately transfer to the ice bath. The skins will slip off easily.

Important: Do not skip the ice bath step—it stops the cooking process and keeps tomatoes firm.

Step 4: Choose Your Freezing Method

You have several options for freezing tomatoes, each with its own benefits. Select the method that best fits your needs and storage space.

The tray-freezing method prevents tomatoes from sticking together, making it easier to use only what you need later. For purees and juices, ice cube trays allow you to portion out small amounts for recipes.

Step 5: Package for Storage

Proper packaging is key to preventing freezer burn and maintaining quality. Use airtight containers or freezer bags to store your tomatoes. Squeeze out as much air as possible from bags before sealing.

Label each package with the date and type of tomato preparation.

• Use freezer-safe bags or containers designed for freezing
• Leave 1-inch headspace for liquids to expand
• Portion sizes based on your typical recipe needs
• Double-bag for extra protection against freezer burn
• Use a permanent marker to label with contents and date

Step 6: Store in the Freezer

Place your packaged tomatoes in the coldest part of your freezer. For best results, freeze tomatoes at 0°F (-18°C) or lower. Properly frozen tomatoes will maintain good quality for 8-12 months, though they’re safe indefinitely at this temperature.

Warning: Do not thaw and refreeze tomatoes, as this can lead to texture degradation and potential bacterial growth.

How to Thaw Frozen Tomatoes Correctly

Thawing tomatoes properly ensures the best texture and flavor for your recipes. Never thaw tomatoes at room temperature for more than 2 hours, as this can promote bacterial growth.

Refrigerator Thawing (Best Method)

Transfer the frozen tomatoes from the freezer to the refrigerator. Allow them to thaw overnight or for about 12 hours. This slow thawing method helps maintain texture and prevents the tomatoes from becoming waterlogged.

Cold Water Thawing (Quick Method)

For faster thawing, submerge the sealed package of tomatoes in cold water. Change the water every 30 minutes to ensure it stays cold. Small packages may thaw in 1-2 hours, while larger ones can take 2-3 hours.

Microwave Thawing (For Immediate Use)

Use the defrost setting on your microwave to thaw tomatoes quickly. This method works best for small portions. Be careful not to overheat, as microwaving can start cooking the tomatoes.

Cooking from Frozen

For many recipes, you can add frozen tomatoes directly to your dish. This works particularly well for soups, stews, and sauces where the tomatoes will cook down anyway. Add a few extra minutes to your cooking time to account for the frozen state.

• Sauces: Add frozen tomatoes directly to the pot
• Soups: Toss in frozen tomatoes with other ingredients
• Stews: Include frozen tomatoes at the beginning of cooking
• Casseroles: Mix in thawed or frozen tomatoes as needed

Common Mistakes to Avoid When Freezing Tomatoes

Even with the best intentions, it’s easy to make mistakes that can affect the quality of your frozen tomatoes. Being aware of these common pitfalls will help you achieve the best results.

1. Not washing tomatoes properly can lead to dirt and bacteria being frozen with your tomatoes. Always wash them thoroughly before freezing.
2. Skipping the blanching step when you want skinless tomatoes. While optional, blanching makes peeling easier and helps preserve color and flavor.
3. Using containers that aren’t freezer-safe can result in freezer burn or cracked containers. Always use bags or containers specifically designed for freezing.
4. Overfilling containers can cause spills and messes as liquids expand when frozen. Leave adequate headspace in containers.
5. Freezing tomatoes with high moisture content without draining can lead to ice crystals forming and a watery product when thawed. For diced tomatoes, consider draining excess liquid before freezing.
6. Not labeling packages makes it difficult to identify contents and track storage times. Always label with the date and type of preparation.
7. Freezing tomatoes that are overripe or damaged will result in poor quality after thawing. Only freeze tomatoes at their peak ripeness.

Tip: If you notice your tomatoes developing ice crystals or freezer burn, it’s likely due to improper packaging or temperature fluctuations. Use a vacuum sealer for the best protection.

Creative Ways to Use Frozen Tomatoes

Frozen tomatoes are incredibly versatile in the kitchen. Here are some delicious ways to use your stash:

• Pasta sauce: Thawed tomatoes break down beautifully into rich, flavorful sauces. Add herbs, garlic, and onions for a quick marinara.
• Soup base: Use frozen tomatoes as the starting point for hearty soups like tomato basil or vegetable soup.
• Stews and chili: Add frozen tomatoes directly to your pot for depth of flavor.
• Tomato juice: Thaw and strain frozen tomatoes for fresh tomato juice.
• Salsa: Combine thawed tomatoes with onions, peppers, and spices for homemade salsa.
• Casseroles: Incorporate thawed tomatoes into baked dishes like lasagna or eggplant parmesan.
• Braised dishes: Use in braised meat recipes where tomatoes add acidity and richness.

According to a study by the University of California, frozen tomatoes retain more vitamin C than canned tomatoes, making them a nutritious choice for your cooked dishes.

How to Freeze Tomatoes Without Blanching

If you’re short on time or prefer to skip the blanching step, you can still freeze tomatoes effectively. Here’s how to do it while maintaining good quality:

Start by washing and drying your tomatoes thoroughly. For whole tomatoes, simply place them on a baking sheet lined with parchment paper, making sure they don’t touch each other. Freeze for 1-2 hours until solid, then transfer to freezer bags or containers.

For sliced or diced tomatoes, cut them into your desired size and spread them on a baking sheet. Freeze until solid, then transfer to storage containers. This method works well for tomatoes you plan to use in cooked dishes where the skin won’t be noticeable.

• Pros of skipping blanching: Faster process, retains more nutrients, simpler preparation
• Cons of skipping blanching: Skins may be tougher, tomatoes may be harder to peel later, slightly more enzyme activity

Important: Tomatoes frozen without blanching may develop a slightly different texture after thawing, but they’re still perfectly safe and flavorful for cooking.

Freezing Tomato Sauce and Puree

Tomato sauce and puree freeze exceptionally well and are convenient for quick meal preparation.

Freezing Tomato Sauce

Prepare your favorite tomato sauce recipe and let it cool completely. Portion the sauce into freezer-safe containers or bags. For easy use, freeze in recipe-sized portions (e.g., 1 cup, 2 cups).

Label with the date and type of sauce.

• Use glass jars designed for freezing (leave 1-inch headspace)
• Plastic containers with tight-fitting lids
• Freezer bags laid flat to save space
• Ice cube trays for small portions to add to recipes

Freezing Tomato Puree

Blend cooked tomatoes into a smooth puree. You can strain out seeds and skins if desired. Freeze in ice cube trays for small portions or in larger containers for bigger recipes.

Tomato puree is perfect for adding to soups, stews, or as a base for other sauces.

When freezing in glass jars, be sure to use jars specifically designed for freezing, as regular canning jars may crack under the pressure of expansion.
