Ingredients and notes

For one microwaved sweet potato you’ll need: 1 medium sweet potato, salt and pepper to taste, and optionally 1 tablespoon butter for a creamier finish. Use a medium potato with smooth, firm skin for best results.

Notes and variations

  • Whole sweet potatoes: Choose medium-sized tubers for even cooking.
  • Butter: Use salted or unsalted butter, or margarine for a dairy-free option.
  • Seasonings: For savory, try garlic powder, paprika, and cumin. For a sweeter profile, add cinnamon, maple syrup, or brown sugar.
  • Toppings: Try sour cream, black beans, feta, olive oil, or a nut butter to change the flavor profile.

Microwaving sweet potatoes

1. Wash the sweet potato and poke several holes in it with a fork.

2. Wrap the potato in a damp paper towel.

3. Place it on a microwave-safe plate and microwave on high for about 10 minutes, or until tender when pierced with a fork. If your microwave is lower wattage or the potato is large, add time in 30-second increments until done.

4. Carefully remove the plate, cut the sweet potato open, and add butter to the center if desired.

Shruthi’s Top Tip

Choose medium-sized sweet potatoes: Medium potatoes cook most evenly in the microwave. For larger potatoes, increase cooking time; for smaller ones, check earlier.

  • Clean thoroughly: Scrub potatoes under cold running water to remove any dirt.
  • Rotate halfway: Turn the potato halfway through cooking for more even results.
  • Check doneness: Pierce with a fork—if it slides in easily the potato is done. Otherwise continue cooking in 30-second intervals.
  • Adjust for wattage: Microwaves vary; high-wattage units will cook faster, so start checking after 5 minutes for very small potatoes.

Serve and store

Serve microwave sweet potatoes while hot as a simple, healthy side for any main course. They’re great plain or dressed up with savory or sweet toppings.

Store: Transfer leftovers to an airtight container and refrigerate for 3–4 days. Reheat in the microwave for about 1 minute or until hot.

Freeze: Let the cooked potato cool completely, wrap tightly in plastic wrap and foil, place in a freezer bag, and freeze up to 6 months. Thaw in the fridge before reheating.
