Step-by-Step Instructions
- Heat olive oil in a large skillet over medium heat. Sauté diced onion for 3-4 minutes until translucent. Add sliced mushrooms and cook until golden, about 5-7 minutes.
- Stir in minced garlic and thyme, seasoning with salt and pepper. Remove from heat and fold in Gruyère cheese, then let cool completely.
- Preheat oven to 200°C (400°F). Roll out thawed puff pastry into a rectangle, approximately 12x16 inches.
- Position the filling along the center of the pastry, cut diagonal strips 1 inch wide on each side, and braid the pastry over the filling.
- Whisk the egg and brush it over the braided pastry. Transfer to a parchment-lined baking sheet and bake for 25-30 minutes until golden brown.
- Cool for 10 minutes before slicing. Optionally garnish with fresh parsley and serve warm.
Notes
For best results, sauté mushrooms thoroughly, cool the filling before adding to pastry, and don't overstuff for clean edges.
