2 Ingredients!

Just one (or at most, two) ingredients are all it takes for this easy recipe. No peeling required!

Sweet potatoes – Select firm potatoes that are free of dried, sunken, or shriveled areas, and have long, uniform shapes that will cook evenly. Try orange, golden, or even purple sweet potatoes, if available. They’re all sweet and delicious but have subtle differences in flavor and consistency.

Variations – Sweet potatoes are delicious by themselves topped with butter or a sprinkle of cinnamon sugar. For a tasty side, try them mashed with a bit of cinnamon and cream. Or baked in a casserole with a crispy crumble topping, or mixed with apple pie filling!

How to Cook a Sweet Potato in the Microwave

Sweet potatoes are ready to enjoy in minutes when you cook them in the microwave.

  1. Use a fork to poke holes 2-3 times on each side of the sweet potato (as per the recipe below).
  2. Microwave on high for 3 minutes.
  3. Flip and cook an additional 2 minutes, or until tender when pierced with a fork.
  4. Allow to cool for 5 minutes. Serve with a tablespoon of butter.

NOTE: Sweet potatoes vary in size and thickness, so expect to adjust the cooking time.

Pro Tip:

To produce some steam to keep the sweet potato moist as it microwaves, place it in a microwave-safe bowl with a tablespoon or two of water.

Serving and Storing Microwave Sweet Potatoes

  • Sweet potatoes are delicious all on their own, slathered with butter, but can also serve as the foundation ingredient in other recipes. For the classic holiday side, mash and top with pecans and marshmallows in a sweet potato casserole.
  • Bakers know sweet potatoes can make a nice substitute for pumpkin puree since they taste so good with the same mixture of warming spices. They are a little more dry and dense, and may require upping the moisture or down-regulating the sweeteners, according to your preference. Try them as an ingredient substitute in recipes for muffins and pie!
  • Cooked sweet potatoes will keep in the refrigerator for 3-5 days and for 6 months or longer in the freezer. Store in freezer containers or bags with the air squeezed out, and thaw at room temperature or in the microwave.
