How to Make Mushroom and Gruyère Puff Pastry Tart
Preheat Oven: Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking.
Sauté Onions: In a skillet over medium heat, melt some butter. Add diced onions and cook until they turn translucent and release their sweet aroma.
Cook Mushrooms: Toss in sliced mushrooms with a pinch of salt. Cook until they’re beautifully browned and have released their moisture—about 5-7 minutes should do.
Add Garlic & Thyme: Stir in minced garlic and fresh thyme leaves. Sauté for another minute until fragrant; your kitchen will smell divine!
Roll Out Pastry: On a lightly floured surface, roll out the puff pastry to fit your baking sheet. Trim any excess dough but leave enough to create a border.
Assemble Tart: Spread the mushroom mixture evenly over the center of the pastry. Sprinkle generously with grated Gruyère cheese before folding up the edges to create a crust.
Egg Wash: Brush the exposed pastry edges with an egg wash to achieve that golden brown finish when baked—this makes all the difference!
Bake & Serve: Place in your preheated oven for 20-25 minutes until puffed and golden. Let it cool slightly before slicing into pieces—enjoy every cheesy bite!
