Ingredients
  • 1 Puff pastry sheet
  • 8 oz Cremini mushrooms, sliced
  • 4 oz Gruyere cheese, shredded
  • 1 Shallot, minced
  • 2 cloves Garlic, minced
  • 1 teaspoon Fresh thyme leaves
  • 2 tablespoons Butter
  • 1 tablespoon Olive oil
  • to taste Salt
  • to taste Black pepper
  • 1 Egg

Sauté the Mushrooms

In a large skillet, melt the butter with olive oil over medium heat. Add the minced shallot and garlic and sauté until softened, about 2-3 minutes. Add the sliced mushrooms and cook until they release their moisture and become tender, about 8-10 minutes. Stir in the fresh thyme leaves, salt, and pepper. Remove from heat and let cool slightly.

Prepare the Puff Pastry

Preheat your oven to 375°F (190°C). Lightly grease a mini muffin tin. Unfold the puff pastry sheet on a lightly floured surface.

Cut and Fill the Tarts

Using a round cookie cutter or a knife, cut out circles from the puff pastry sheet. Gently press each circle into the mini muffin tin cups. Sprinkle a small amount of Gruyere cheese into each cup, then top with the mushroom mixture, and finish with another sprinkle of Gruyere cheese.

Bake the Tarts

Beat the egg in a small bowl and brush the edges of the puff pastry with the egg wash. This will help the pastry turn golden brown. Bake in the preheated oven for 18-20 minutes, or until the puff pastry is golden brown and the cheese is melted and bubbly. Let the tarts cool slightly in the tin before transferring them to a wire rack to cool completely. Serve warm.
