Preheat the oven to 375°F (190°C).
In a large bowl, toss the potato wedges with the olive oil and season evenly with salt, black pepper, and garlic powder.
Arrange the seasoned wedges in a single layer on a rimmed baking sheet, leaving space between pieces for even roasting.
Bake for 45 minutes, turning once if desired, until the potatoes are tender and golden on the edges.
While the wedges bake, combine the melted butter and hot pepper sauce in a microwave-safe cup or small saucepan and warm until combined.
When the wedges are done, drizzle the butter–hot sauce mixture over them and toss gently with tongs or a spatula to coat evenly.
