September & October Produce: A Freeze-Drying Guide

As summer fades into fall, farmers' markets and grocery stores fill up with a distinct lineup of seasonal produce. September and October are a good window to stock up while these fruits and vegetables are at their best — and freeze-drying is one of the most effective ways to hold onto that flavor well past the season.

What's in Season

Apples. From Honeycrisp to Granny Smith, fall's signature fruit works for pies, cider, and snacking alike.

Pears. Juicy and sweet this time of year, pears are a natural fit for salads or desserts.

Squash. Butternut, acorn, and spaghetti squash are all in season — good for roasting or simmering into soup.

Sweet potatoes. Versatile and nutritious, whether baked, mashed, or turned into fries.

Beets. Earthy root vegetables that work well roasted, pickled, or added to salads.

Grapes. At their sweetest in the fall, good for snacking or making into jellies.

Carrots. Fresh-harvested and crunchy, a reliable addition to almost any dish.

Why Freeze-Dry This Time of Year

Freeze-drying (technically called lyophilization) removes moisture from food after it's been frozen. The food sits in a vacuum chamber at low temperature, where the ice sublimates directly into vapor, leaving behind a lightweight, shelf-stable version of the fresh produce — nearly all of the original nutrients intact.

What You Get

• Nutrition retained. Freeze-drying preserves nearly all of the original nutritional content.
• A long shelf life. Properly stored freeze-dried produce can last up to 25 years.
• Less pantry clutter. Lightweight and compact, good for camping, hiking, or just freeing up space.
• Flexibility in the kitchen. Use it in cooking, baking, snacking, or blended into smoothies.

Stocking up while apples, squash, and the rest of this fall lineup are at their peak — and freeze-drying what you can't use right away — is a simple way to keep that harvest-season flavor on hand well into winter.
