Method
- Heat the oven to 400°F.
- Line an 18x13-inch rimmed baking sheet with parchment paper.
- Pat the asparagus dry.
- Divide the asparagus into 8 bundles of 3 spears.
- Season the bundles with the black pepper.
- Unfold the puff pastry and cut it into 8 strips about 1 1/4 inches wide.
- Brush one side of each pastry strip with Dijon mustard.
- Sprinkle the pastry strips with Parmesan.
- Wrap one slice of prosciutto around the middle of each asparagus bundle.
- Wrap a pastry strip around each bundle in a loose spiral, with the cheese side facing inward.
- Set the bundles seam-side down on the baking sheet.
- Beat the egg with the water in a small bowl.
- Brush the exposed pastry with the egg wash.
- Bake for 20 to 25 minutes, until the pastry is puffed and deep golden and the asparagus is tender when pierced with a knife.
- Rest the bundles on the baking sheet for 5 minutes before serving.
Notes
Keep the puff pastry cold while assembling so it stays easy to handle. Refrigerate leftovers for up to 3 days; freezing is not recommended because the pastry can lose its crisp texture. For a vegetarian variation, omit the prosciutto.
