Step 1: Preheat and Prep
Preheat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or lightly grease it with cooking spray. This prevents sticking and makes cleanup effortless.

Step 2: Prepare the Asparagus
Wash the asparagus thoroughly and pat completely dry with kitchen towels—moisture prevents proper roasting and crisping. Trim off the woody bottom ends (about 1-2 inches) by either cutting them with a knife or bending each spear until it naturally snaps where the tender part begins. Discard the tough ends.

Step 3: Season the Asparagus
Place the trimmed asparagus in a medium bowl. Drizzle with olive oil and sprinkle with black pepper (and garlic powder if using). Toss gently to coat all the spears evenly with the oil and seasonings. The oil helps the asparagus roast beautifully and adds flavor.

Step 4: Cut the Prosciutto
If your prosciutto slices are very large, cut them in half lengthwise to create long strips. You want each strip to be just wide enough to wrap around an asparagus spear 2-3 times with slight overlap. Smaller slices may not need cutting.

Step 5: Wrap the Asparagus
Take one seasoned asparagus spear and one strip of prosciutto. Starting about an inch below the asparagus tip, wrap the prosciutto in a spiral motion down the spear, overlapping slightly as you go. The prosciutto should wrap around 2-3 times, leaving the very top of the tip and the bottom stem exposed. Don’t wrap too tightly—leave a little room for heat circulation. Place the wrapped spear on your prepared baking sheet. Repeat with remaining asparagus and prosciutto.

Step 6: Arrange on Baking Sheet
Arrange the prosciutto-wrapped asparagus bundles on the baking sheet in a single layer with a little space between each one. Don’t crowd them or they’ll steam instead of roast, and the prosciutto won’t get crispy.

Step 7: Roast
Roast in the preheated 400°F oven for 10-12 minutes, until the asparagus is tender-crisp (it should still have a slight bite) and the prosciutto is crispy and lightly browned around the edges. Thicker asparagus may need 13-15 minutes, while very thin spears might be done in 8-10 minutes. You can flip the bundles halfway through for even crisping, but it’s not necessary.

Step 8: Finish and Serve
Remove from the oven and let cool for 2-3 minutes. If desired, drizzle with balsamic glaze, sprinkle with grated Parmesan cheese, add a squeeze of fresh lemon juice, or garnish with lemon zest and fresh herbs. Serve immediately while hot and crispy.
