Learn the simple, reliable method for baking sweet potatoes in the oven to achieve a perfectly fluffy interior and a slightly caramelized, crisp skin. This recipe requires minimal ingredients and serves as a fantastic, healthy side dish.

Ingredients

Scale
  • 4 medium sweet potatoes (about 8–10 ounces each)
  • 1 tablespoon olive oil
  • 1 teaspoon coarse salt
  • 1/2 teaspoon black pepper

Instructions

  1. Preheat your oven to 400°F (200°C). Line a baking sheet with aluminum foil for easy cleanup.
  2. Scrub the sweet potatoes well under running water. Dry them completely with a paper towel. Moisture on the skin prevents crisping.
  3. Prick each sweet potato deeply 6 to 8 times all over using a fork. This allows steam to escape and prevents bursting.
  4. Rub the entire surface of each potato lightly with olive oil.
  5. Sprinkle the coarse salt and black pepper evenly over the oiled skins.
  6. Place the prepared sweet potatoes directly onto the foil-lined baking sheet. Do not wrap them in foil; this steams them instead of baking them for crispy skin.
  7. Bake for 45 to 60 minutes. The exact time depends on the size of your potatoes.
  8. Check for doneness by squeezing the sides gently; they should yield easily, or insert a sharp knife with no resistance. The internal temperature should reach 205°F.
  9. Remove from the oven and let them cool slightly before slicing open lengthwise. Fluff the inside flesh with a fork.

Notes

  • For a sweeter result, you can rub the potatoes with a small amount of coconut oil instead of olive oil.
  • If you prefer a softer skin, pierce the potatoes but skip the oil and salt coating.
  • To make twice baked sweet potatoes, scoop out the cooked flesh, mix it with your desired additions (like cinnamon butter or cheese), and return it to the skins to bake for 10 more minutes.
  • For meal prep, bake the potatoes ahead of time and store them whole in the refrigerator for up to 4 days. Reheat in the oven or microwave.
