Ingredients

Scale
  • 4 medium sweet potatoes, scrubbed clean
  • 1 tablespoon olive oil
  • 1 teaspoon coarse salt
  • 1/2 teaspoon black pepper

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). This high heat helps crisp the skin.
  2. Prick each sweet potato several times all over using a fork. This allows steam to escape and prevents bursting.
  3. Rub the entire surface of each potato with olive oil. This is key for achieving crispy skin.
  4. Sprinkle the potatoes evenly with salt and pepper.
  5. Place the seasoned potatoes directly onto the oven rack. Do not use foil; direct heat contact is necessary for crisping the skin.
  6. Bake for 40 to 55 minutes, depending on the size of the potatoes. Start checking for doneness around 40 minutes.
  7. The sweet potatoes are done when the skin is slightly wrinkled and crispy, and you can easily pierce the center with a fork.
  8. Remove from the oven. Slice open lengthwise and fluff the inside with a fork before serving with your preferred toppings.

Notes

  • For meal prep, bake the potatoes ahead of time, store them whole in the refrigerator for up to four days, and reheat them in a 350 degree oven for 10 minutes to refresh the texture.
  • To achieve a sweeter flavor profile, you can add a light sprinkle of brown sugar over the skin before baking.
  • If you prefer a savory variation, rub the potatoes with garlic powder and a pinch of smoked paprika along with the salt and pepper.
