Print Recipe

Learn the best way to cook sweet potatoes in the oven for a guaranteed fluffy inside and caramelized, crispy skin every time. This easy oven baked sweet potato method requires no foil and is perfect for a healthy side dish or meal prep.

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 degrees Fahrenheit (200 degrees Celsius). This high heat helps achieve that crispy skin.
  2. Scrub the sweet potatoes well under running water to remove any dirt. Dry them completely with a paper towel; moisture prevents crisping.
  3. Prick each sweet potato deeply 6 to 8 times all over using a sharp fork. This allows steam to escape and helps create a fluffy sweet potato inside.
  4. Rub the entire surface of each potato with olive oil. Distribute the coarse salt and black pepper evenly over the oiled skins.
  5. Place the seasoned sweet potatoes directly onto the center oven rack. Do not use foil or a baking sheet. Baking directly on the rack allows air to circulate, which is key for crispy skin sweet potato oven results.
  6. Bake for 40 to 55 minutes. The exact time depends on the size of your potatoes. Start checking at 40 minutes.
  7. The sweet potatoes are done when the skin is slightly wrinkled and crispy, and a knife inserted into the center slides in with no resistance.
  8. Remove from the oven and let them cool slightly for about 5 minutes before slicing them open lengthwise. Fluff the interior with a fork.
  9. Serve immediately with your favorite toppings for an easy sweet potato side dish.

Notes

  • For a savory variation, try topping your hot, fluffy sweet potato with 1 tablespoon of softened butter mixed with 1 minced garlic clove and a pinch of dried thyme.
  • If you are meal prepping, you can bake these ahead of time. Store cooled, whole potatoes in the refrigerator for up to 4 days. Reheat in a 350 degree oven for 10 minutes to crisp the skin again.
  • To achieve extra caramelized skin, you can briefly place the potatoes under the broiler for 1-2 minutes at the very end, watching carefully to prevent burning.
