The time to microwave a sweet potato depends on its size and the microwave's power, but generally:

• For one medium sweet potato, microwave on high for about 5 minutes. Check by piercing with a fork; it should go in easily. If not done, continue microwaving in 1-minute increments until tender

• Another method is to microwave for 2-3 minutes per side (total 4-6 minutes), turning halfway through. Larger potatoes may need more time, adding 1-minute increments as needed

• If microwaving multiple sweet potatoes, start with 5 minutes for one, then add about 2 minutes per additional potato, rotating halfway through

• Wrapping the sweet potato in a damp paper towel can help keep it moist during cooking

• After microwaving, let the sweet potato rest for a few minutes before cutting to allow steam to finish cooking it inside

In summary, expect around 5 to 10 minutes total for a medium sweet potato, adjusting for size and quantity, with fork tenderness as the doneness test.
