Preheat oven to 450°F.
Dice the sweet potatoes into ¾” cubes, leaving the skins on.
In a large bowl, mix sweet potatoes with olive oil, garlic powder, pepper, and salt.
Place the sweet potatoes on a baking sheet lined with parchment paper in a single layer.
Bake for about 25 minutes until the cubes are fork-tender and browned on the bottom. Serve warm. Leftovers store up to 5 days refrigerated.
