Step 1

Preheat the oven to 425 degrees F (220 degrees C). Line a baking sheet with parchment paper.

Step 2

Cut potatoes into 1 1/2-inch wedges. Place in a large bowl with onion and bell pepper. Add olive oil, garlic powder, salt, and pepper; mix well. Place mixture onto the prepared baking sheet.

Step 3

Roast in the preheated oven, stirring halfway through, until potatoes are tender, about 30 minutes.

Step 4

Turn on the broiler and broil until crispy, checking often to prevent burning, 2 to 5 minutes.
