Instructions
- Preheat oven to 400 degrees. On a floured surface, roll the puff pastry into a 16-by-10-inch rectangle. Trim uneven edges. Place pastry on a baking sheet lined with a silpat or parchment paper. With a sharp knife, lightly score pastry dough 1 inch in from the edges to mark a rectangle. Using a fork, pierce dough inside the markings at 1/2-inch intervals. Bake until golden, about 15 minutes.
- Remove pastry shell from oven, and sprinkle with Gruyere. Trim the bottoms of the asparagus spears to fit crosswise inside the tart shell; toss in olive oil then arrange in a single layer over Gruyere. Season with salt, pepper, and garlic powder. Bake until spears are tender, 20 to 25 minutes. After, lightly drizzle with good quality truffle oil.
