• Great as an appetizer or main with a salad. • Check after 15 minutes, as baking time may vary.

Ingredients

• 1 sheet puff pastry (thawed in the fridge) • 2 cups Gruyere cheese, grated • 14 oz or 4 cups mushrooms (mixed, porcini, or your choice), sliced • 2 tbsp butter • 1 tbsp extra virgin olive oil • 3 sprigs fresh thyme (or 1 tsp dried thyme) • 1 small egg, lightly beaten (for egg wash)

4) Sprinkle all the Gruyere cheese evenly over the center of the pastry.
5) Spread the sautéed mushrooms over the cheese.
6) Brush the pastry edges with beaten egg for a golden finish.
