How to Cook Sweet Potato in the Microwave: Step by Step
Step 1–2: Prepare the Sweet Potato
#1 Lightly brush the skin with a bit of coconut oil or clean water.
#2 Pierce the sweet potato with a fork several times so steam can escape while it cooks.
Step 3–5: Season and Wrap
#3 Sprinkle some cinnamon over the sweet potato for extra flavor.
#4 Wrap the sweet potato in a lightly damp paper towel. This traps moisture and keeps the flesh soft.
Step 6–8: Microwave and Check
#5 Put the prepared sweet potato on a microwave-safe plate and set the timer for five minutes.
#6 After the first five minutes, turn the sweet potato over and microwave it for another five minutes.
#7 Check the sweet potato. A fork should slide in easily. If it is still firm, add 1–2 minutes and test again.
#8 Let it rest for a minute (it will be very hot), then slice it open and enjoy.
Tips for the Best Microwave Sweet Potato
- Pick similar sizes: Medium potatoes cook evenly; very large ones may need 12–15 minutes.
- Adjust for wattage: Lower-wattage microwaves need extra time, so check early and often.
- Add toppings: Butter, honey, Greek yogurt, or a pinch of salt all work well.
- Keep the skin on: It holds in moisture and adds fiber.
