Ingredients

Scale
  • 1 sheet puff pastry, thawed (about 1 lb)
  • 1 bunch fresh asparagus, trimmed (about 12 oz)
  • 1 cup Gruyere cheese, grated (about 4 oz)
  • 1/4 cup Parmesan cheese, grated (optional, about 1 oz)
  • 2 teaspoons Dijon mustard
  • 1 large egg, beaten (for egg wash)
  • 1 tablespoon olive oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 teaspoon fresh thyme leaves (optional)

Instructions

  1. Preheat oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper.
  2. On a lightly floured surface, roll out the puff pastry to approximately 10×14 inches. Transfer to the prepared baking sheet.
  3. Using a sharp knife, score a 1-inch border around the edge of the pastry, being careful not to cut all the way through. Prick inside the border with a fork.
  4. Spread Dijon mustard evenly inside the scored border.
  5. Sprinkle Gruyere cheese evenly over the mustard, followed by Parmesan cheese if using.
  6. In a mixing bowl, toss trimmed asparagus with olive oil, salt, and pepper. Arrange spears side by side over the cheese layer.
  7. Sprinkle fresh thyme leaves over the asparagus.
  8. Brush the exposed pastry border with beaten egg.
  9. Bake for 22-25 minutes, until edges are puffed and golden and cheese is bubbly.
  10. Let the tart rest for 5 minutes before slicing and serving.

Notes

Keep the pastry cold until ready to bake for maximum flakiness. Dry asparagus thoroughly to prevent soggy pastry. For gluten-free, use gluten-free puff pastry. Swap Gruyere for Swiss, Emmental, or Fontina if needed. Add lemon zest or toasted pine nuts for extra flavor. Leftovers keep for up to 3 days refrigerated; reheat in the oven for best texture.
