Start by washing your potato as you normally would. Don't be afraid to really scrub (a scrub brush will help) — you need to get all the dirt off. Pat dry.
If you plan to serve the potato whole, rub the skin with olive oil and season with salt and pepper.
Pierce the potato three or four times with a fork — this allows steam to escape so there are no messy explosions. Place the potato onto a microwave-safe plate.
For one sweet potato, microwave on 100 percent power for 5 minutes, rotating halfway through. Add 2 minutes for each additional potato.
If it isn't fork-tender (or easily pierced with a paring knife) after 5 minutes, continue to microwave in 1-minute increments until done. Be sure to protect your hands when removing the hot plate.
Slice the potato lengthwise and serve with butter, salt, pepper, and/or brown sugar as desired. Or top it off with brown sugar-cinnamon butter!
