Preheat oven to 425°F and line a baking sheet with parchment paper.
Pat asparagus spears completely dry with paper towels, then arrange in a single layer on the prepared baking sheet.
Drizzle asparagus with olive oil and sprinkle with garlic powder, salt, and black pepper, tossing to coat evenly.
Roast for 10 minutes, then remove from oven and sprinkle both cheeses evenly over the asparagus.
Return to oven and roast for an additional 3-5 minutes until cheese is melted and bubbly, then serve immediately.
