Learn the simple, foolproof method for baking sweet potatoes in the oven to achieve a perfectly fluffy interior and a caramelized, crispy skin. This easy recipe makes a fantastic, healthy side dish for any meal.

Ingredients

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

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
  2. Scrub the sweet potatoes thoroughly under running water to remove any dirt. Pat them completely dry with a paper towel. This step helps achieve crispy skin.
  3. Pierce each sweet potato 5 to 6 times deeply all over using a sharp fork or a paring knife. This allows steam to escape and prevents bursting.
  4. Rub the exterior of each potato lightly with olive oil. Distribute the sea salt and pepper evenly over the skins.
  5. Place the prepared sweet potatoes directly onto the middle oven rack. Do not use foil or a baking sheet, as this traps steam and prevents the skin from crisping.
  6. Bake for 45 to 60 minutes. The exact time depends on the size of your potatoes. They are done when the skin is slightly wrinkled and caramelized, and a fork easily pierces the center.
  7. Remove the potatoes from the oven. Let them cool for 5 minutes before slicing them open lengthwise down the center. Gently squeeze the sides to fluff the interior flesh.
  8. Serve immediately with your favorite toppings.

Notes

  • For the best texture, avoid wrapping the potatoes in foil. Baking directly on the rack promotes crispy skin.
  • If you prefer a sweeter result, you can rub the potatoes with a small amount of coconut oil instead of olive oil before seasoning.
  • To make twice baked sweet potatoes, scoop out the flesh after baking, mix it with your desired filling, return it to the skins, and bake for an additional 10 minutes.
  • If you are meal prepping, bake the potatoes ahead of time and store them whole in the refrigerator for up to four days. Reheat in the oven or microwave.
