How to Freeze Tomatoes: Whole, Peeled, and Ready for Cooking

Knowing how to freeze tomatoes lets you keep a glut of ripe fruit for later cooking without canning a full batch. Frozen tomatoes do not hold their shape the way fresh ones do, but they work well in sauces, soups, stews, and chili. This guide explains the two main approaches described in university extension guidance, whole tomatoes and peeled tomatoes, and it points out where the published sources leave gaps.

Quick answer

  • Pack whole or quartered tomatoes into freezer containers with about 1 inch of headspace, seal them, and freeze.
  • To peel tomatoes first, dip them in boiling water for 30 to 60 seconds until the skins split, move them to cold water, and slip off the skins.
  • Expect frozen tomatoes to turn limp after thawing, so plan to use them in cooked dishes rather than fresh salads.

How we chose

This article draws on two sources that were opened and checked on 2026-10-27: an NDSU Extension publication titled “Canning and Freezing Tomatoes and Making Salsa” (FN175) and the National Center for Home Food Preservation (NCHFP) freezing overview. Both pages were read in full, and only statements found on those pages are presented as guidance. Retail recipe sites and forum posts were set aside because their freezing methods differed from one another and from the extension text. Where the sources are silent, the article says so.

Decide between whole and peeled tomatoes

NDSU Extension gives two routes for whole fruit. The first is whole or quartered tomatoes, which are prepared the same way as for canning by the hot pack method and then packed into freezer containers. The second is peeling the tomatoes before freezing, which removes the skins and produces a cleaner product for sauces. Both routes are described in the same publication, so the choice comes down to how you plan to use the tomatoes later.

Peeling makes sense if you intend to puree or chop the tomatoes for sauce, because skins can become tough and separate during cooking. Leaving the skins on takes less time and is a reasonable choice for stews or soups that will be blended or strained later. The NCHFP freezing overview notes that blanching slows or stops enzyme action that affects flavor, color, and texture, which is one reason many home cooks treat the dipping step as a worthwhile quality measure even when they plan to peel only later.

Peel the tomatoes before freezing

NDSU Extension gives a clear peeling method. Dip the tomatoes in boiling water for 30 to 60 seconds, or until the skins split, then dip them in cold water. Once they are cool enough to handle, slip off the skins and remove the cores. The skins usually come away easily at this point because the heat has loosened them from the flesh.

Work in small batches so the water stays hot and the tomatoes do not sit in the cold bath too long. Use a slotted spoon to move them, and keep a bowl nearby for skins and cores. A kitchen towel makes it easier to hold a tomato while you slip off the skin. Tomatoes that are very ripe tend to peel more easily than firm ones, though very soft fruit may break apart during handling.

For a faster process, you can skip peeling entirely and freeze whole tomatoes as they are. This works well when you need tomatoes for cooking, since the skins can be removed later after thawing if you prefer, or you can leave them in for a sauce that will be run through a sieve.

Freeze whole or quartered tomatoes

NDSU Extension says to pack whole or quartered tomatoes into freezer containers and leave 1 inch of headspace. Seal the container and place it in the freezer. Headspace gives the contents room to expand as they freeze and helps protect the surface of the fruit from drying out. Label each container with the date and the form of the tomatoes, such as whole, quartered, or chopped, so you can find the right batch when you cook. If you are still growing the crop, our guide to growing tomatoes from seed to harvest covers the timing that leads to a freezing-ready harvest.

The same publication also describes juice and mixtures, which are packed with 1 and a half inches of headspace. If you freeze tomato juice or a prepared sauce base, follow that measurement. Using the larger headspace for juice is a practical difference rather than a safety rule stated by the source, so keep the two batches separate in your freezer.

Many home cooks find it helpful to freeze tomatoes in portions that match a typical recipe. A quart container may hold enough for a pot of soup, while a pint may suit a small batch of sauce. Portion sizes are a convenience choice, not a requirement from the sources checked here.

Plan how you will use frozen tomatoes

NDSU Extension states that frozen whole or sliced tomatoes become limp after thawing and are unsatisfactory to serve as fresh produce. That is a quality limit, not a warning against freezing. It means frozen tomatoes are best used in dishes where texture matters less, such as sauces, soups, stews, chili, and braised dishes.

For a related method that keeps tomatoes at room temperature for longer use, read about other ways to preserve tomatoes. Thaw frozen tomatoes in the refrigerator or add them directly to a pot while cooking. Expect extra liquid to release as they thaw, so you may need to simmer a sauce longer to thicken it. Frozen tomatoes can also be blended straight from the freezer into a smoothie-style base for soups, though the sources do not describe that use, so treat it as a kitchen habit rather than a published method.

If you plan to can tomatoes later or use them for preserves, see our guide to preserving tomatoes and follow tested recipes from your extension office rather than relying on freezer guidance alone. Freezing is a separate method with its own steps, and the two should not be mixed without tested instructions.

What we could not verify

The two sources give a dependable framework for freezing tomatoes, but they do not answer every question a home cook will have. The points below are not confirmed by the pages checked for this article.

What the sources do not say

  • The NDSU publication does not specify a freezer storage time for tomatoes, so this article does not give one.
  • The sources checked do not recommend a freezer temperature for tomatoes beyond general storage, so no temperature is given here.
  • The NCHFP freezing overview links to separate pages for packaging and storage time rather than stating them on the page checked, so those details remain unconfirmed.
  • The sources do not describe a method for freezing tomato sauce or paste, so this article does not include one.

Frequently asked questions

Do tomatoes need to be blanched before freezing?

The NCHFP freezing overview explains that blanching slows enzyme action that affects flavor, color, and texture. NDSU Extension describes dipping tomatoes in boiling water for peeling, which is a separate step from blanching for quality.

How much headspace should you leave for frozen tomatoes?

NDSU Extension says to leave 1 inch of headspace when packing whole or quartered tomatoes into freezer containers, and 1 and a half inches for juice and mixtures.

Are frozen tomatoes good for fresh eating?

NDSU Extension states that frozen whole or sliced tomatoes become limp after thawing and are unsatisfactory to serve as fresh produce. They are better suited to cooked dishes.

How long can you keep frozen tomatoes?

The NDSU publication checked does not state a freezer storage time, so this article does not give a number. Label containers with the date and check your own freezer guidance.

Can you freeze tomatoes without peeling them?

Yes. NDSU Extension describes packing whole or quartered tomatoes without peeling. Peeling is an optional step before freezing, most useful if you plan to make a smooth sauce.
