How to Store Tomatillos

Knowing how to store tomatillos well makes the difference between a crop that lasts for weeks and one that shrivels or spoils in a few days. Tomatillos are sold and harvested with a papery husk, and that husk does most of the protective work. Storage depends on whether the husk is still on, how fresh the fruit was when picked, and whether you plan to use the fruit within a couple of weeks or keep it longer. The three non-retail extension sources used here agree on the main points: keep husks on for short storage, use paper bags in the refrigerator, and freeze husked fruit for longer keeping. This guide walks through each method and notes where the sources differ.

Quick answer

Keep tomatillos in their husks and store them in a paper bag in the refrigerator. South Dakota State University Extension gives 1 to 2 weeks.
Texas A&M AgriLife Extension gives about 2 weeks under refrigeration for ripe fruit with husks.
For longer storage, remove the husks, rinse the fruit, and freeze it, or keep the husked fruit refrigerated in a sealed bag as Texas A&M AgriLife Extension describes.
Choose firm fruit with a light brown, fresh-looking husk. A shrivelled or dried husk is a sign the fruit is past its best.

How we chose

This guide relies on three non-retail sources: a state university extension guide from South Dakota State, a Texas A&M AgriLife Extension horticulture guide, and an Oregon State University Extension page. Each one was opened and checked on 2026-10-27, and the quoted sentences come from the fetched text. Retail and recipe sites were not used for any storage claim. For a fuller understanding of how fresh produce should be handled after harvest, the general guidance in how to store freshly harvested vegetables covers the common principles of cooling, airflow and moisture.

Keep tomatillos in the husk in the refrigerator

The husk is the first line of protection. South Dakota State University Extension says, “Tomatillos can be kept in a paper bag in the fridge with the husks on for 1 to 2 weeks.” The same guide notes that the fruit does not need a curing phase after harvest, and that it should be placed in “a cool, well-ventilated space between 42 degrees and 60 degrees Fahrenheit” before refrigeration.

The paper bag matters. The same South Dakota State source warns that “If the fruit is kept in an airtight bag, it will spoil much faster, so keeping it in paper bags is essential.” Paper allows some air movement and stops condensation from collecting on the husks. A plastic bag traps moisture and speeds rot, so it should not be used for husk-on fruit.

Storage also depends on the temperature. The fruit is sensitive to cold, and the South Dakota State guide says improper storage can lead to chilling injury and spoilage. Store the bag on a refrigerator shelf rather than in a freezing corner, and check it every few days.

Check freshness before you store

Storage only works for fruit that was in good condition when it went into the bag. Texas A&M AgriLife Extension says the husk is the best guide: “The condition of the “husk” is a good indication of the freshness of the fruit.” The guide adds, “The husk should be light brown and fresh looking, not shriveled and dried.”

A husk that is green and tight is usually a sign that the fruit is not yet ripe. A husk that is dry, papery and broken, or one that has split open to show the fruit, means the fruit has been exposed and will not keep well. The South Dakota State guide describes harvest readiness in similar terms, saying the fruit is ready when “it completely fills the husk and easily falls off the plant when picked.” Sort the crop before storage, and use the fruit with the weakest husks first.

Avoid storing fruit with bruises or cuts. Those spots spoil first and can spread to nearby fruit in the bag. Set aside any damaged fruit for immediate use.

Store husked tomatillos

Husk removal changes the storage plan. Texas A&M AgriLife Extension describes husk removal as the step for longer storage. Its guide states that “If longer storage is desired, remove husks and place ripe fruit in a sealed plastic bags in the refrigerator,” and that fresh, ripe fruit with husks on keeps under refrigeration for about 2 weeks.

The sources do not fully agree on the bag. Texas A&M recommends a sealed plastic bag for husked fruit, while South Dakota State warns against airtight bags for husk-on fruit. The two statements describe different conditions, since the South Dakota warning concerns fruit kept with its husk. Check husked fruit often, and use it sooner rather than later.

Husking also makes the fruit sticky. The South Dakota State guide notes that “The fruit may be sticky if the husk is removed,” which is one reason rinsing comes before freezing.

Freeze tomatillos for longer storage

Freezing is the method the sources describe for keeping tomatillos beyond a few weeks. Oregon State University Extension gives the steps in order. It says, “To freeze tomatillos, remove their husks and rinse them under cold water in a colander to wash off the sticky residue.” The fruit can then be frozen in several forms, since the guide states, “You can freeze tomatillos chopped, diced, sliced or whole.”

For whole or sliced fruit, the guide describes a tray method: “Whole or sliced tomatillos can be frozen on a cookie sheet and when frozen transfer to freezer bags.” Spreading the pieces on a tray before bagging keeps them from freezing into one block, so you can take out only what you need. Remove as much air as you can from the bag before sealing it.

Label each bag. The Oregon State guide says, “Label with content and date.” A clear label helps you use the oldest bags first. For a broader look at freezing other garden produce, see how to freeze vegetables from the garden.

The sources do not give a freezer shelf life for tomatillos, so this guide does not state one. Use frozen tomatillos within the period your household normally keeps frozen produce, and check bags for freezer burn before use.

Preserving tomatillos beyond freezing

Canning and salsa-making are common ways to preserve tomatillos, but none of the three sources used here gives a canning procedure or an acid amount. Do not treat a home-canned tomatillo product as safe unless it follows a tested method from a source such as the USDA or a state extension service. A recipe that is not tested for home canning is not safe to store on a shelf. For general guidance on keeping other garden produce, see how to preserve tomatoes, which covers the same principle of following tested procedures.

If you make tomatillo salsa or sauce for the refrigerator only, keep it cold, use it within a short period, and discard any jar or container that looks, smells or tastes wrong. Storage in the fridge is not the same as shelf-stable preservation, and the two should not be mixed up.

What we could not verify

This section lists what the sources do not establish. It is a limit on this guide, not a claim that the answer is known.

What the sources do not say

The sources do not agree on the best bag for husked fruit. Texas A&M describes a sealed plastic bag for husked fruit, and South Dakota State warns against airtight bags for husk-on fruit. Oregon State does not address bag type for husked fruit.
No verified source in this set gives a freezer shelf life for tomatillos.
No verified source in this set gives a canning procedure, a processing time or an acid amount for tomatillos.
The sources do not give a counter or room-temperature storage time that is safe for husked fruit.
Extension documents for some other states were checked, but their text could not be read in full, so their freezing and canning steps are not used here.

Frequently asked questions

Should tomatillos be stored with the husk on?

For short storage, yes. South Dakota State University Extension recommends keeping the husks on and storing the fruit in a paper bag in the refrigerator for 1 to 2 weeks. The husk helps protect the fruit and gives a visible sign of freshness.

Can tomatillos be kept on the counter?

The three sources used here focus on refrigerator storage and freezing. They do not give a safe counter storage time. Because of the risk of chilling injury, cool and ventilated storage is the approach the sources describe.

Why should tomatillos go in a paper bag?

South Dakota State University Extension states that airtight bags cause faster spoilage for husk-on fruit, and that paper bags are essential for keeping them. Paper allows some air movement and reduces moisture buildup.

How do I know if a tomatillo is still fresh?

Check the husk. Texas A&M AgriLife Extension says the husk should be light brown and fresh looking, not shriveled and dried. Fruit with cuts, bruises or a split husk should be used first or discarded.

Do I need to rinse tomatillos before freezing?

Yes. Oregon State University Extension says to remove the husks and rinse the fruit under cold water in a colander to wash off the sticky residue before freezing.
