Pre-heat the Oven– Adjust the oven rack to the center position and the temperature to 400°F (204°C).
Prepare the Asparagus– Wash and thoroughly dry. Trim off the tough fibrous ends to give about 7-inch long spears. Evenly coat with 2 tablespoons olive oil, salt, garlic powder, and black pepper.
Wrap the Asparagus– Divide the seasoned asparagus into 8 even-sized bundles. Tightly wrap one slice of prosciutto around the center of each bundle. The ham should stick together, but you can secure it with a toothpick if needed.
Brush and Season– Line a baking sheet with foil and place a wire rack on top. Place the wrapped bundles on the wire rack. Brush the prosciutto with some of the remaining 1 tablespoon of olive oil. Lightly season with black pepper.
Roast– Cook until the prosciutto gets lightly brown and crisp, and the asparagus is tender, about 13 to 15 minutes.
To Serve– Serve warm topped with some parmesan cheese.
Notes
Make-Ahead: The prosciutto-wrapped asparagus can be assembled, covered, and stored in an airtight container up to two days before roasting.
Storing: Cool completely and store in the refrigerator for up to 3 days.
Reheating: Loosely cover and reheat on the high setting in the microwave in 15 to 30-second intervals until hot. Alternatively, bake at 350ºF (177ºC) until hot.
