Ingredients you’ll need

Ingredients needed to make slow cooker sweet potatoes.
  • Sweet potatoes — 6 to 8 medium sweet potatoes, about 8 ounces each. Choose similar-sized potatoes so they cook evenly.
  • Optional toppings — butter, chives, sour cream, salt, and pepper, or any toppings you prefer such as maple syrup, honey, cinnamon, or brown sugar.

How to make these slow cooker sweet potatoes

Sweet potatoes pricked with a fork and added to a crockpot.
  • Wash and scrub the sweet potatoes well. Do not dry them completely—the residual moisture helps them steam while cooking. Prick each potato several times with a fork or paring knife.
  • Arrange the sweet potatoes in the slow cooker in a single layer. If needed, you may add a second layer, but do not stack more than two layers to ensure even cooking.
  • Cook on low for 6 to 8 hours, or on high for 3 to 4 hours, until the potatoes are easily pierced with a fork.
  • Using tongs, carefully remove the potatoes and let them cool until they are safe to handle. For a slightly crisp exterior, transfer them to a baking sheet and broil in the oven for a few minutes.
  • Slice each potato lengthwise, squeeze the ends to open, and add your preferred toppings.

Tips and notes

  • Smaller sweet potatoes will finish toward the lower end of the time range (about 6 hours on low or 3 hours on high). Extra-large potatoes will need more time.
  • Handle cooked sweet potatoes gently; they will be very soft and can break apart easily.
  • No extra water is necessary—the potatoes release moisture as they cook and steam in the slow cooker.
  • Thoroughly scrub potatoes to remove dirt, but avoid leaving them dripping wet when placing them in the crockpot.
  • Do not stack more than two layers to prevent uneven cooking.
  • For a sweeter finish, drizzle with honey or maple syrup and sprinkle cinnamon or brown sugar before serving.

Frequently asked questions

Do I need to wrap the sweet potatoes in foil?

No. Wrapping is unnecessary; the slow cooker steams and cooks the potatoes evenly without foil.

How do I store cooked sweet potatoes?

Store cooled sweet potatoes in an airtight container in the refrigerator for 4 to 5 days. They reheat well for meal prep.

Can I freeze crockpot sweet potatoes?

Yes. Cool completely, wrap individual potatoes in plastic wrap or foil, place in a freezer-safe bag or container, and freeze up to 3 months. Thaw overnight in the refrigerator before reheating.

How do I reheat cooked sweet potatoes?

Reheat in the microwave wrapped with a damp paper towel for 2 to 3 minutes, or in a 350°F oven for 10 to 15 minutes until warmed through.
