You can achieve a perfectly cooked baked sweet potato with a fluffy interior and slightly crisp skin using this simple oven method. This recipe requires minimal effort and delivers naturally sweet results ideal for any meal.

Ingredients

Scale
  • 4 medium sweet potatoes (about 810 ounces each)
  • 1 teaspoon coarse salt (for seasoning skin)
  • 1 tablespoon olive oil (optional, for crispier skin)

Instructions

  1. Preheat your oven to 400°F (200°C). Place an oven rack in the center position.
  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 a crispier skin.
  3. Prick each sweet potato deeply 5 to 6 times all over using a fork. This allows steam to escape and prevents the potato from bursting.
  4. If you want a crispier skin, rub the outside of each potato lightly with olive oil. Sprinkle the coarse salt evenly over the entire surface of each potato.
  5. Place the prepared sweet potatoes directly onto the center oven rack. Do not use foil, as foil traps steam and results in a softer, steamed skin rather than a crisp one.
  6. Bake for 45 to 60 minutes. The exact time depends on the size of your potatoes.
  7. Check for doneness by gently squeezing the sides; the potato should yield easily. You can also insert a sharp knife into the center; it should slide in with no resistance.
  8. Remove the potatoes from the oven. Let them cool for 5 to 10 minutes before slicing them open lengthwise. Fluff the interior flesh with a fork.
  9. Serve immediately with your favorite toppings.

Notes

  • For meal prep, bake the potatoes, let them cool completely, and store them whole in the refrigerator for up to 4 days. Reheat them in the oven or microwave when ready to eat.
  • If you prefer a softer skin, you may wrap the potatoes loosely in foil, but direct heat yields the best texture.
  • To enhance natural sweetness, you can lightly brush the inside flesh with a small amount of maple syrup or honey after baking.
