  • Grill
  • Aluminum Foil


  • 3 Sweet Potatoes medium
  • 2 tablespoon Olive Oil extra virgin
  • ½ teaspoon Rosemary crushed
  • ¼ teaspoon Onion Powder
  • ¼ teaspoon Salt
  • ¼ teaspoon Black Pepper


  • Turn on your grill.
  • Wash and peel the potatoes, cut in half lengthwise, and then into slices.
  • Divide the sweet potato slices onto 2 pieces of aluminum foil.
  • Drizzle with olive oil and add the rosemary, onion powder, salt & pepper. Mix them up a bit to evenly distribute the spices.
  • Wrap the potatoes up securely in 2 layers of aluminum foil (about 12x15 inches)
  • Grill for 30 minutes, flipping them over halfway through.
  • Remove from the grill and let sit for 5 minutes. Open carefully and serve.


  • If your grill has a temperature gauge, heat it up to 400-450 degrees.
  • It is entirely up to you whether you peel your potatoes or not. Leaving the skin on will provide you with some extra fiber; just be sure to wash them well.
  • Crush the rosemary by pulsing in a coffee grinder for a few seconds or place between two pieces of waxed paper or in a heavy-duty food storage bag and run a rolling pin over them.
  • Feel free to mix up the spices as you like. Sometimes I will add cumin, cayenne pepper and/or chili powder to spice it up.
  • I've also made them with sliced onions and peppers, which is delicious too!
