How to Store Garlic and Keep It from Sprouting

A whole head of garlic can stay fresh for several months when stored outside the refrigerator in a cool, dry, dark place. How you store garlic depends on whether it is peeled or still in a whole head: peeled or crushed garlic spoils much sooner and needs different storage. The humidity in a refrigerator may speed up sprouting, so a cool, dry pantry or kitchen cupboard is a better place for whole heads. Peeled or chopped garlic should be refrigerated and used within a short time because more of it is exposed to air.

How can you store garlic to keep it from sprouting?
A few simple steps can help keep garlic from sprouting or molding:
• Store whole heads in a breathable mesh or paper bag in a cool, dark place.
• Do not seal garlic in a plastic bag; trapped moisture can speed up sprouting.
• Keep peeled cloves in an airtight container in the refrigerator and use them within a few days.
• If you need to store chopped or crushed garlic for a longer time, freeze it instead of leaving it at room temperature.

What storage mistakes should you avoid?
Some storage mistakes can speed up sprouting and create serious food-safety risks. Moist conditions or a closed container can increase the chance of mold and sprouting. Do not leave chopped or crushed garlic in olive oil at room temperature for days: the oxygen-free conditions can allow bacteria that cause botulism to grow. Garlic oil left unrefrigerated on the counter for a long time carries the same risk. Removing a sprout does not by itself make garlic safe; discard garlic that has softened or developed mold.

How can you use frozen garlic?
Peeled cloves or crushed garlic frozen in small portions can remain usable for several months. Freezing may soften the texture after thawing, so frozen garlic is better for cooked dishes than for eating raw. You can add it straight from the freezer to a pot without thawing it first.

Why do garlic-oil mixtures need special care?
Bacterial spores that may be present on garlic can grow in a moist, oxygen-free environment, such as garlic stored in olive oil at room temperature. Make homemade garlic-oil mixtures in small amounts, refrigerate them, and use them within a short time. Do not leave them at room temperature for days. Do not eat a garlic-oil mixture if it smells suspicious or has bubbles.

In brief, store whole heads in a cool, dry place and refrigerate peeled or crushed garlic for short-term use. Avoid plastic bags to slow sprouting, and keep garlic-oil mixtures refrigerated to reduce the risk of botulism. Buying small amounts of fresh garlic more often is usually more practical and safer than storing a large amount for a long time.
