Can You Freeze Garlic?
You CAN freeze garlic.
Freezing Fresh Garlic
To freeze fresh garlic you can simply place the unpeeled garlic bulbs in air-tight freezer storage bags and remove the cloves as needed. Similarly, you can freeze peeled and chopped garlic wrapped tightly in plastic wrap or in airtight freezer storage bags.
Freezing Garlic in Oil
You can freeze garlic in oil for up to several months. Prepare your mixture consisting of 2 parts oil to 1 part garlic and pour into glass mason jars allowing for ½" headspace. Freeze immediately. You can store the mixture in a refrigerator with temperatures below 40°F up to 7 days, but do not ever store the mixture at room temperature as you run the risk for the development of botulism.
Freezing Fresh Garlic from the Home Garden
If you are freezing garlic freshly harvested from your home garden, you need to cure the bulbs first. To cure the bulbs, arrange them in a single file on newspaper and store in a dry room with good air circulation out of direct sunlight. In about two weeks they will be cured and ready to be frozen when their peels become papery.
