Do you have a glut of amazing fresh tomatoes in your kitchen?

The good news is that easiest way to preserve tomatoes is through freezing. Lucky for you, freezing tomatoes couldn’t be easier. Let’s tackle tomato season together!

There are both pros and cons of freezing tomatoes. Pros: it’s SO easy! You won’t need any special equipment or need to know any canning skills. Cons: you’ll need space in the freezer both to freeze them and store them. And frozen tomatoes aren’t suitable for use in all cooking situations.

In this tutorial, I’ll walk you through four different ways of freezing fresh tomatoes:

  • Freezing whole tomatoes – both peeled and unpeeled
  • Freezing tomato sauce and spaghetti sauce
  • Freezing tomato paste
  • Freezing stewed tomatoes

If you end up running out of freezer space and still have more tomatoes to preserve, check out our tutorial on Dehydrating Tomatoes for a shelf-stable option.

How to Freeze Whole Tomatoes

How to Freeze Whole Tomatoes Without Peeling

Start with clean and dry tomatoes. If you’d like, you can use a paring knife and core the stem end of the tomato.

This step is not necessary but will make the frozen tomatoes more versatile to use after they have been thawed.

Line a rimmed baking sheet with parchment and place the tomatoes on the baking sheet with enough space so they’re not touching, and freeze for 4 hours.

Break apart any tomatoes that may have stuck together and transfer them to freezer-proof storage.

When whole frozen tomatoes are thawed, the skins slip right off, which makes them so easy to add to recipes like Butternut Squash Chili or Instant Pot Bruschetta Chicken.

Freezing Peeled Whole Tomatoes

Peeling tomatoes to freeze is an extra step, but will only add about 10 minutes to the process. And the good news is, it’s super easy. For more in-depth info into the process, check out our post on How to Blanch and Peel Tomatoes.

In a large mixing bowl combine water and ice. Next up, bring a large pot of water to a boil on the stove.

Using a paring knife, remove the stem/core from the tomatoes – OR – cut an “x” on the bottom of the tomato.

Add the tomatoes to a pot of boiling water and boil them until you see the skins start to come off (about 1-2 minutes). Use a slotted spoon and remove the tomatoes and place in the ice water.

Working with the tomatoes one at a time, remove any skin that hasn’t already slipped off. Once they are peeled you can slice the tomatoes in half (to remove all the seeds) or leave them whole. I like to place the peeled tomatoes in a strainer for a few minutes to drain any additional water.

Line a rimmed baking sheet with parchment and place the tomatoes on the baking sheet with enough space so they’re not touching, and freeze for 4 hours.

Break apart any tomatoes that may have stuck together and transfer them to freezer-proof storage.

And the best part about peeling tomatoes before freezing them? Set the peels aside to dehydrate later to make into homemade tomato powder. Tomato powder is an amazing flavor booster for rice, soups, and stews.

How to Freeze Tomato Sauce and Spaghetti Sauce

If you have leftover canned or homemade tomato sauce or spaghetti sauce, freeze the extras for later!

Freezing tomato sauce in easy-to-use portions gives you the most flexibility for cooking. Most store-bought cans of tomato sauce are 14-15 oz, which translates to ~1.5-2 cups.

If the tomato sauce is warm, allow it to fully cool before freezing. This will prevent it from becoming icy in the freezer. Transfer the sauce to freezer-safe containers.

I love using 1/2-cup Souper Cubes, 1-cup Souper Cubes, and 2-cup Souper Cubes. Once frozen, I transfer the cubes of tomato sauce to reusable freezer bags. You can also use plastic freezer bags, plastic containers, or canning jars.

To freeze tomato sauce in canning jars, use only wide-mouth jars. Allow for 1 inch of headspace, which is the space between the top of the food and the top of the jar. This gives the sauce room to expand as it freezes.

To use tomato sauce frozen in canning jars, do not thaw the cold jars in hot water or the microwave. This can lead to cracking. Instead, allow it to sit at room temperature on the counter for a few hours, or overnight in the fridge.

If you need inspiration, check out my recipes for Crockpot Spaghetti Sauce and Cherry Tomato Sauce, which use fresh tomatoes, and Freezer Spaghetti Sauce which uses canned diced tomatoes and canned tomato sauce.

How to Freeze Tomato Paste

Most store-bought cans of tomato paste are 6 oz, which translates to ~1/2-3/4 of a cup. The 2-Tbsp Souper Cubes, 1/2 cup Souper Cubes, or 1-cup Souper Cubes are perfect for smaller portions of freezing tomato paste.

You can also freeze in small plastic freezer bags or even “dollops” of tomato paste frozen on parchment. Line a baking sheet with parchment and spoon tomato paste onto the parchment. Freeze for 2-3 hours and then remove the individual portions of frozen paste to freezer bags.

Use tomato paste in recipes like Creamy Instant Pot Tortellini Soup and Sugar-Free Barbeque Sauce.

How to Freeze Stewed Tomatoes

If you have leftover canned or homemade stewed tomatoes, freeze the extras in easy-to-use portions. You can check out my tutorial on Canning Stewed Tomatoes for step-by-step instructions on how to make this tasty ingredient.

Most store-bought cans of stewed are 14-15 oz, which translates to ~1.5-2 cups. Similar to the process of freezing tomato sauce, allow the stewed tomatoes to fully cool before freezing.

Transfer cooled stewed tomatoes to your favorite freezer containers, including any juices that have accumulated in the stewing process.

How to Store Frozen Tomatoes

Whole tomatoes are best stored in freezer-safe bags with any extra air removed.

Tomato sauce, spaghetti sauce, and stewed tomatoes are best stored in 1/2-2-cup portions in wide-mouth canning jars or freezer-safe bags.

Tomato paste is best stored in smaller portions of 2-TBSP to 1/2 cups.

How Long Will Frozen Tomatoes Last?

Whole tomatoes, and portions of tomato sauce, spaghetti sauce, stewed tomatoes, and tomato paste will last for 6-9 months in the freezer.

You can prolong their life by making sure the tomatoes and tomato products are fully cooled before going into the freezer. This prevents ice from forming on them, leading to freezer burn which can impact the taste in the long run.

How to Use Frozen Tomatoes

Frozen tomatoes are not intended for fresh eating after thawing like in grilled tomatoes with cheese, or salads, and you definitely can’t just slice one up for a delicious BLT.

But frozen tomatoes work amazing for recipes like Gluten-Free Tomato Soup or in Instant Pot Lasagna Soup.

In a year with epic garden crops of tomatoes, I have even frozen them whole and then canned them during the winter when I have more time and the kitchen isn’t exceptionally hot.

Frequently Asked Questions

Can you freeze raw tomatoes?

Yes, absolutely! When you stick raw tomatoes in the freezer, it’s a simple and hands-off process. This will save you a lot of time if you need to preserve a lot of tomatoes at once.

Do You Have to Blanch Tomatoes Before Freezing Them?

No, you can easily freeze tomatoes without blanching them first.

That being said, blanching and peeling them prior to freezing will make their use more versatile when they are thawed.

What is the best way to freeze whole tomatoes?

The best way will depend on how much time you have and how many tomatoes you need to preserve at once.

If you have an extra 10-15 minutes, blanching, peeling, and then freezing the tomatoes whole is my preference. Peeling them before freezing gives you more flexibility on how to use them later.

What is the best way to store tomatoes in the freezer?

It all depends on how much space you have and what type of tomato products you are freezing.

For whole tomatoes, I prefer freezing them on a baking sheet and storing them in freezer-safe bags.

For tomato sauce, spaghetti sauce, or stewed tomatoes, I prefer to freeze them in 1-cup Souper Cubes or 2-cup Souper Cubes and then transferring them to freezer-safe bags.

For tomato paste, I use 2 tbsp Souper Cubes or 1/2 cup Souper Cubes.

  1. I wonder if you could just pop them into the freezer bag without flash freezing first. If the skins are dry, maybe they don’t stick to each other once frozen? Have you ever tried it? Thanks for all your great preserving instructions; next I’m going to check out how to freeze celery!

    1. I have not had good luck with that but I’m usually freezing a lot at once. Maybe try with a small quantity first to see if it works for you. And then expand.
