Learn the simple method to bake sweet potatoes in the oven for a fluffy interior and perfectly crisp skin without using foil.

Ingredients

Scale
  • 4 medium sweet potatoes
  • 1 tablespoon olive oil
  • 1 teaspoon coarse sea salt

Instructions

  1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
  2. Wash the sweet potatoes thoroughly under running water and dry them completely with a paper towel. Moisture prevents crisping.
  3. Prick each sweet potato four to five times deeply all over using a fork.
  4. Rub the outside of each potato lightly with olive oil.
  5. Sprinkle the coarse sea salt evenly over the entire surface of each potato.
  6. Place the prepared sweet potatoes directly onto the oven rack. Do not use a baking sheet or foil.
  7. Bake for 45 to 60 minutes, depending on size, until the skin is crisp and the interior yields easily when squeezed gently.
  8. Remove from the oven and let them cool for 5 minutes before slicing open lengthwise.

Notes

  • For a savory variation, mix 1 tablespoon of melted butter with 1 clove of minced garlic and brush it on the skin before baking.
  • For a sweeter side, sprinkle with cinnamon and a drizzle of maple syrup after slicing open.
  • These potatoes are excellent for meal prepping; store them whole or halved in the refrigerator for up to four days.
