Ingredients
1 sheet frozen puff pastry, thawed
1 tablespoon Dijon mustard
1 cup grated Gruyère cheese
1 pound asparagus, trimmed
1 tablespoon olive oil
Salt and freshly ground black pepper to taste
1 egg, beaten (for egg wash)
Instructions
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
On a lightly floured surface, roll out puff pastry to a 10x15-inch rectangle. Transfer to prepared baking sheet. Score a 1-inch border around the edges without cutting through. Prick the inner pastry with a fork.
Spread Dijon mustard evenly inside the scored border. Sprinkle Gruyère cheese over the mustard.
Toss asparagus with olive oil, salt, and pepper. Arrange asparagus spears in a single layer over the cheese, alternating tips and ends.
Brush the border with beaten egg. Bake for 25-30 minutes, until pastry is golden and puffed.
Let cool for 5 minutes before slicing. Serve warm or at room temperature.
Tips
For a vegetarian version, ensure the puff pastry is made with vegetable shortening.
Add a squeeze of lemon juice before serving for brightness.
Leftover tart can be reheated in a 350°F oven for 5-10 minutes.
