You can freeze fresh garlic as whole bulbs, as peeled or unpeeled cloves, or in a chopped form. Freezing, however, may cause the garlic to lose some of its crunch and flavor.
Although the freezing process may cause the flavor and texture of garlic to diminish somewhat, many cooks feel the taste remains superior to garlic from a jar, according to Fresh Bites Daily. Store bulbs, cloves or chopped garlic from 10 to 12 months in the freezer. Use plastic freezer bags, sturdy plastic bowls, glass containers or aluminum foil to keep garlic's pungent odors and flavors from spreading to other foods. Use frozen garlic in the same manner as fresh garlic; it works especially well in soups, sauces and stews. In general, you do not need to defrost frozen garlic before using it.
