Instructions

1. Preheat oven to 400 degrees.

2. On a floured surface, roll the puff pastry into a 16-by-10 inch rectangle. Trim edges if needed. Place pastry on a baking sheet. With a sharp knife, lightly score pastry dough 1 inch in from edges to make a rectangle. Using a fork, pierce dough inside the markings at ½-inch intervals. Bake until just golden, about 12-15 minutes.

3. Remove pastry shell from oven, and sprinkle with Gruyere.

4. Arrange asparagus in a single layer over cheese, alternating ends and tips.

5. Brush with oil, season with salt and pepper, and top with parmesan. Bake until spears are just tender, yet crisp, about 8-12 minutes.
