Course:
Appetizer
Cuisine:
French
Servings: 6
Ingredients
- olive oil
- 1-2 Tablespoons butter
- 1/2 onion sliced
- 3-4 cups Cremini mushrooms, sliced
- 2-3 tablespoons fresh thyme
- kosher salt
- 2-3 teaspoons balsamic vinegar
- ¼ cup Gruyère cheese grated
- 1 pie crust packaged or from scratch
Method
-
Heat a large sauté pan over medium heat. Add enough oil to coat the pan. When oil shimmers add the onions and cook until softened and translucent, about 15 minutes.
-
Remove onions from pan and set aside.
-
Wipe out the pan and re-heat over medium-high heat. Add butter and equal amount of olive oil to the skillet. When melted add the mushrooms and thyme. Season with a light sprinkle of salt. Cook until mushrooms are softened and have released water, for about 8-10 minutes.
-
Add the balsamic vinegar and reduce the heat to medium-low. Cook for another 5 minutes to slightly thicken the balsamic.
-
Remove from heat and combine with the cooked onions. Cool to room temperature before assembling.
-
Preheat your oven to 400°F and line a baking sheet with parchment paper.
-
Roll pie crust to about a 12” circle on a lightly floured board.
-
Spoon the mushroom mixture onto the center of the dough, leaving a 2-inch border all around. Evenly spread the cheese over the filling. Gently fold over the crust, overlapping the edges. Gently press the folds together.
-
Brush the folded edges of the crust with an egg wash or milk.
-
Bake for 30 minutes or until the crust has become a lovely golden brown and cheese has melted.
-
Let cool to room temperature, about 20 minutes before cutting and serving.
Cooks Notes
A refrigerated pie shell works very well and is quite easy for this Galette, however if you prefer to make your own please feel free. If you need a recipe for a pie crust here is a great one.
