Can You Freeze Sweet Potatoes?

Can you freeze sweet potatoes?

Yes, sweet potatoes freeze well after cooking. Raw sweet potatoes don't freeze well due to: high water content (about 77 percent water) creating large ice crystals; active enzymes causing browning and texture decline; the starch separating from the rest of the potato. Cooking solves these problems by denaturing enzymes and rearranging starches. Forms of sweet potato that freeze well: mashed sweet potatoes (excellent for holiday meals); baked sweet potato flesh (scooped from skin); cubed cooked sweet potatoes; roasted sweet potato chunks; sweet potato fries (par-fried); sweet potato casserole; sweet potato pies; sweet potato soup; sweet potato baby food. Frozen cooked sweet potatoes last 10-12 months for best quality at 0°F (-18°C); safe indefinitely. Both orange-flesh and white-flesh sweet potatoes freeze with similar results. The orange varieties (Beauregard, Jewel, Garnet) are most common; purple sweet potatoes (Stokes) freeze similarly.

How do you freeze sweet potatoes?

Cook before freezing for best results. For mashed sweet potatoes: bake whole sweet potatoes at 400°F until tender (about 45-60 minutes); cool; scoop flesh from skins; mash with butter and seasonings; portion into freezer bags or containers; press out air; freeze flat. For cubed cooked: peel and cube sweet potatoes; boil 8-10 minutes until tender-crisp; drain and cool; spread on baking sheet; flash freeze; transfer to labeled freezer bags. For roasted: cube and toss with olive oil and seasonings; roast at 425°F for 25-30 minutes until tender; cool; freeze in single layer; bag once solid. For sweet potato fries: cut into fries; blanch 4-5 minutes in boiling water; drain and pat dry; freeze in single layer; bag. For sweet potato casserole: assemble casserole (with marshmallows on top); freeze unbaked in casserole dish; bake from thawed. Pre-portion into meal-sized bags for convenience.

How do you reheat frozen sweet potatoes?

Multiple reheating methods work well. Stovetop (best for mashed): transfer frozen mashed sweet potatoes to a saucepan; add 1-2 tablespoons of butter and/or milk per cup; heat over low heat, stirring constantly; add seasonings as needed. Microwave: transfer to microwave-safe bowl; cover; microwave on 50% power; stir every 2-3 minutes; add butter or cream as needed. Oven (best for casseroles): thaw mashed sweet potatoes or sweet potato casserole overnight in refrigerator; bake covered at 350°F for 30-40 minutes; uncover for 15 more minutes. Roasted cubes: spread frozen on baking sheet; drizzle with oil; bake at 400°F for 15-20 minutes. Sweet potato fries: bake from frozen at 425°F for 18-22 minutes; flip halfway. Don't thaw at room temperature; the texture deteriorates.
