Topped with baby Bella mushrooms and Gruyere cheese, Cheesy Mushroom Pastries are the perfect appetizer!
Season to taste with salt and pepper
Preheat the oven to 400°F.
Line two baking sheets with parchment paper.
Cut the puff pastry into 16 2-inch squares and place eight on each baking sheet. (you will likely have some leftover dough)
Brush the egg wash onto each square.
Top each square with a sprinkle of cheese, a spoonful of the mushroom mixture
Bake for 10 minutes, remove from oven and top each square with a little more cheese. Bake for another 5 minutes or until the puff pastry is golden brown.
Top with fresh thyme.
