Here’s how to microwave a sweet potato: the right way! Cook it with this method and it comes out perfectly moist every time.


  • 1 sweet potato (see notes below on timing based on size)


  1. Prick and wrap in wet paper towel: Rinse the potato, removing any attached tendrils. Prick it all over with a fork and wrap it in a wet paper towel.
  2. Cook, flip, then cook again: Microwave on High power using the following chart for timing, making sure to flip and continue cooking on the second side:
    • Small (6 to 8 ounces, 2″ thick): 2 to 3 minutes per side
    • Medium (9 to 12 ounces, 2″ thick): 3 to 4 minutes per side
    • Large (13 to 16 ounces, 3″ thick): 4 to 5 minutes per side
    • Extra Large (1 ¼ pound, 3″ thick): 6 to 7 minutes per side
    • Two potatoes: Double the cook time; start checking a few minutes before to assess doneness
  3. Assess doneness and continue if necessary: Prick both sides to assess doneness, taking care because it is hot. If the fork goes in all the way with no give, it is done. Otherwise, continue cooking at 1 minute intervals until tender.
