Instructions
1
Preheat oven to 375°F.
2
Line a large baking sheet with parchment paper.
3
Add butter and olive oil to a large skillet over medium-high heat. Once butter has melted, add shallots and a pinch of kosher salt. Saute for 4-5 minutes until soft then add mushrooms and garlic. Cook for 7-8 minutes until reduced in volume by ~½ and taken on golden brown color. Mix in thyme and cook for 1 minute more. Transfer mixture to a bowl and let cool for ~10-15 minutes.
4
Remove puff pastry from fridge. Score top layers of puff pastry along all 4 sides of the dough (leaving 1-inch border). Transfer the pastry along with the parchment paper to a large baking sheet.
5
Prick the dough with a fork all over (only the center, not the edges).
6
Sprinkle the cheese over the dough. Top with cooled mushroom mixture. Brush the edges of the tart with beaten egg. Bake the tart for about 20-25 minutes or until golden.
