Learn the simple, no-foil method to bake sweet potatoes that guarantees a perfectly fluffy interior and delightfully crispy skin every time. This is the best way to cook sweet potatoes for an easy, healthy side dish or meal prep staple.

Ingredients

Scale
  • 4 medium sweet potatoes (about 810 ounces each)
  • 1 tablespoon olive oil
  • 1 teaspoon coarse sea salt
  • 1/2 teaspoon black pepper

Instructions

  1. Preheat your oven to 400°F (200°C). Place an oven rack in the center position.
  2. Scrub the sweet potatoes well under running water to remove any dirt. Pat them completely dry with a paper towel. This step is key for crispy skin.
  3. Pierce each sweet potato 5 to 6 times deeply all over using a sharp fork. This allows steam to escape.
  4. Rub the entire surface of each potato with olive oil. Distribute the sea salt and 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.
  6. Bake for 45 to 60 minutes. The exact time depends on the size of your potatoes. Start checking at 45 minutes.
  7. The potatoes are done when the skin is slightly wrinkled and crisp, and you can easily pierce the center with a knife or fork with no resistance.
  8. Remove from the oven. Let them rest on a cutting board for 5 minutes before serving.
  9. Slice the potato lengthwise down the center, from end to end, and gently squeeze the sides inward to fluff the interior. Serve immediately with your favorite toppings.

Notes

  • For a savory baked sweet potato topping, try mixing softened butter with minced garlic, fresh thyme, and a pinch of smoked paprika.
  • If you prefer a sweeter profile, skip the oil and salt/pepper, and instead rub the skin lightly with coconut oil and sprinkle with cinnamon before baking.
  • To prepare for meal prep, bake the potatoes, let them cool, and store them whole in the refrigerator for up to 4 days. Reheat in the oven or microwave.
