Learn the simple, no-foil method to bake sweet potatoes perfectly every time, resulting in a caramelized skin and a soft, fluffy center. This is a reliable, healthy side dish for any meal.

Ingredients

Scale
  • 4 medium sweet potatoes (about 810 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 parchment paper or aluminum foil for easy cleanup.
  2. Scrub the sweet potatoes thoroughly under running water to remove any dirt. Pat them completely dry with a paper towel. Drying the skin helps it crisp up.
  3. Prick each sweet potato deeply 4 to 6 times all over using a sharp fork. This allows steam to escape and prevents the potato from bursting.
  4. Rub the exterior of each potato lightly with the olive oil. Sprinkle evenly with the coarse salt and black pepper.
  5. Place the prepared sweet potatoes directly onto the lined baking sheet. Do not wrap them in foil, as this steams the skin instead of crisping it.
  6. Bake for 45 to 60 minutes. The exact time depends on the size of your potatoes.
  7. Check for doneness by squeezing the sides gently; the potato should yield easily, or insert a knife into the center—it should slide in with no resistance.
  8. Remove from the oven and let them cool slightly before slicing open lengthwise. Fluff the inside flesh with a fork before adding your desired toppings.

Notes

  • For a caramelized surface, increase the oven temperature to 425°F for the last 10 minutes of baking.
  • If you prefer a twice baked sweet potato, scoop out the cooked flesh, mix it with butter and spices, refill the skins, and bake for an additional 10 minutes.
  • Sweet potatoes are excellent for meal prep; bake them ahead of time and reheat them in the oven or microwave when ready to eat.
