Preheat oven to 400°F and line a baking sheet with parchment paper.
Divide asparagus into 8 bundles of 3-4 spears each.
Wrap each bundle with one slice of prosciutto, starting at the bottom and spiraling up, leaving the tips exposed.
Place bundles on the baking sheet, drizzle with olive oil, and sprinkle with black pepper and garlic powder.
Roast for 12-15 minutes until prosciutto is crispy and asparagus is tender.
Remove from oven, sprinkle with parmesan cheese and drizzle with lemon juice before serving.
