Learn the simple, no-foil method to bake sweet potatoes in the oven until the skin is crisp and the inside is perfectly fluffy. This is the best technique for a healthy side dish or meal prep component.

Ingredients

Scale
  • 4 medium sweet potatoes, scrubbed clean
  • 1 tablespoon olive oil
  • 1 teaspoon coarse salt

Instructions

  1. Preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius).
  2. Prick each sweet potato several times deeply all over using a fork or sharp knife. This allows steam to escape.
  3. Rub the entire surface of each potato with olive oil.
  4. Sprinkle the coarse salt evenly over the oiled skin of each potato.
  5. Place the potatoes directly onto the middle oven rack. Do not use foil or a baking sheet.
  6. Bake for 45 to 60 minutes, depending on size. Start checking at 45 minutes.
  7. The potatoes are done when the skin is firm and slightly wrinkled, and a fork easily pierces the center.
  8. Remove from the oven and let them cool for 5 minutes before slicing open and serving with your preferred toppings.

Notes

  • For a crispier skin, place the potatoes directly on the oven rack rather than on a pan.
  • If you plan to mash or use the potatoes for twice-baking, you can reduce the initial baking time slightly.
  • To make garlic butter sweet potatoes, mix 2 tablespoons softened butter with 1 minced garlic clove and a pinch of parsley; stir into the hot, opened potato.
