Ingredients
For the pie dough:
1 ¼ cups all-purpose flour
1 ½ teaspoons salt, divided
½ cup unsalted butter, cubed, at room temperature
1 tablespoon melted butter
¼ cup ice water
For the filling:
¼ cup butter
1 pound cremini mushrooms, thinly sliced
1 small onion, diced
2 cloves garlic, finely chopped
1 teaspoon salt
½ teaspoon ground black pepper
1 teaspoon fresh thyme, finely chopped
¼ cup crème fraîche or sour cream
1 cup gruyere cheese, shredded, divided
Other ingredients:
1 egg, beaten (for egg wash)
2–3 fresh thyme twigs (for garnish)
Instructions
Prepare the pie dough: Combine flour and ½ teaspoon salt in a mixing bowl, then add cubed butter. Use a pastry cutter (or 2 knives) to incorporate butter into the flour until large pea-sized pieces remain. Add ice water and mix with your hands until most of the flour is incorporated and the dough is smooth. Wrap the dough tightly in plastic wrap and refrigerate for 30 minutes.
Once firm, roll out the dough on a floured surface into a ¼-inch thick circle or oval. Transfer to a parchment-lined baking sheet and refrigerate.
Prepare the filling: Preheat oven to 375°F. Melt butter in a skillet over medium-high heat, add mushrooms and cook for 3-5 minutes. Add onion, garlic, salt, and pepper, cooking until mushrooms are golden and liquid has evaporated. Stir in thyme.
Mix crème fraîche and ½ cup gruyere cheese in a bowl. Spread this mixture onto the dough base, leaving a 1-inch border. Top with mushroom filling and remaining cheese. Fold edges over and brush with egg wash.
Bake for 50-55 minutes until golden. Let cool for 5 minutes, garnish with thyme, slice, and serve warm.
