If your region has mild winters, the best way to keep your carrots is to leave them in the garden under mulch until you’re ready to use them. In colder regions, pull up your carrots before a hard frost sets in and freeze them (sliced or diced) after 2 minutes of blanching. Besides using the carrots as a cooked vegetable, you can use them in muffins and cakes. For these baking uses, first grate the carrots, then give them a quick dip in boiling water. Freeze the grated carrots in recipe-size portions.
You can dry sliced carrots into chips. You can either eat the chips or grind them into flakes. The flakes add sweetness to stews and soups.
