This rich and savory tart is a perfect way to showcase asparagus in a decadent and delicious way. The tart is made by rolling out puff pastry and topping it with a mixture of grated Gruyere cheese, heavy cream, and fresh herbs. Blanched asparagus spears are then arranged on top of the cheese mixture in a decorative pattern. The tart is baked until the pastry is golden brown and the cheese is melted and bubbly. The result is a rich and satisfying dish that is perfect for a special occasion or a cozy night in.
