Then, prep your sweet potato by cutting off the ends off to create a flat surface.
Next, slice your sweet potatoes into cubes, fries, rounds, or wedges and place on a large baking sheet. You want the thickness to be anywhere between 1/2-inch to 1-inch. Just make sure that all slices are the same thickness.
Drizzle with a generous amount of olive oil and season with garlic powder, sea salt, and pepper. Then, toss with your hands to make sure everything is coated.
Roast at 400ºF for around anywhere from 20-30 minutes, tossing every 10 minutes. The thicker you slice your sweet potatoes, the longer they will have to roast.
