How to Store Sweet Potatoes - Refrigerate or Not

Sweet potatoes are nutritious, delicious, and surprisingly easy to store — but like regular potatoes, they're often stored incorrectly. Should you refrigerate sweet potatoes? Here's everything you need to know.

Should You Refrigerate Sweet Potatoes?

No — do not refrigerate raw sweet potatoes. Cold temperatures cause a condition called "chilling injury" in sweet potatoes — the flesh develops a hard core, loses its natural sweetness, and takes on an unpleasant taste and texture when cooked. Sweet potatoes prefer temperatures between 55–60°F (13–15°C), which is warmer than most refrigerators.

How to Store Sweet Potatoes at Room Temperature

1. Store in a cool, dark, dry spot — A pantry, cupboard, or cellar away from direct sunlight and heat is ideal. Avoid storing near the stove or in warm areas.
2. Use a basket, paper bag, or open container — Sweet potatoes need airflow. Never store in a sealed plastic bag — trapped moisture causes mold and rot.
3. Don't wash before storing — Wash only right before cooking. Surface moisture accelerates decay.
4. Keep away from other produce — Sweet potatoes emit ethylene gas. Store away from other fruits and vegetables that are sensitive to ethylene.

When Is It Okay to Refrigerate Sweet Potatoes?

• Cooked sweet potatoes — Always refrigerate cooked sweet potatoes. Store in a ComSaf Airtight Container and use within 3–5 days.
• Cut raw sweet potatoes — If cut and not cooking immediately, submerge in cold water in a sealed container and refrigerate. Use within 24 hours.

How Long Do Sweet Potatoes Last?

• Whole sweet potatoes (room temperature counter): 1–2 weeks
• Cut raw sweet potatoes (water, fridge): up to 24 hours
• Cooked sweet potatoes (airtight container, fridge): 3–5 days

How to Freeze Sweet Potatoes

Cook sweet potatoes first — bake, boil, or steam until tender. Cool completely, then mash or cut into chunks. Store in a SPLF Reusable Freezer Bag. Frozen cooked sweet potatoes last up to 12 months and reheat beautifully.
