Ingredients
For the crust
- 1 ¼ cups all-purpose flour
- 1 tsp kosher salt
- 1 tbsp granulated sugar
- ¼ cup grated Parmesan cheese
- 6 tbsp unsalted butter
- 3-5 tbsp cold water
For the filling
- 2 tbsp unsalted butter (or bacon grease)
- ½ medium onion diced
- 8 oz cremini mushrooms sliced
- 3 slices bacon fried and sliced
- 4 large eggs
- 1 cup whole milk
- ¼ cup heavy cream
- 1 cup shredded Gruyère cheese
- 2 tsp Dijon mustard
- 1 tsp kosher salt separated
- 1 tsp freshly ground black pepper separated
Instructions
For the crust
- Combine the flour, salt, and sugar in the bowl of a food processor. Pulse twice to combine.
- Add the grated Parmesan cheese and butter. Pulse until the pieces of butter are the size of peas, about five 3-second pulses.
- With the processor running, slowly add 3 tablespoons of water. When a dough is formed and tested by making a fist, it’s done. If it does not hold together, add another tablespoon of water.
- Dump the dough onto clear plastic wrap. Knead with the plastic and wrap tightly into a disk. Chill for at least half an hour.
- Once chilled, remove from the plastic and roll on a floured surface to a 12-inch rough circle. Place in a 9-inch tart pan or a 10-inch pie dish. Let the dough fall into the corners and remove any excess over the edges. Place shell in the freezer to firm up for 20 minutes.
- Once cold, remove from freezer. Line with parchment and weights (or dry beans). Bake at 375°F until the bottom is set, 15 minutes.
- Remove parchment and weights and continue baking until crisp and golden, 5-7 minutes.
- Remove the shell from the oven and set aside.
For the filling
- Melt the butter or bacon grease in a 12-inch skillet.
- Add the onion and sauté until translucent, 5 minutes.
- Add the sliced mushrooms, ½ tsp salt, and ½ tsp black pepper. Continue to sauté until the mushrooms are cooked down, 8 minutes. Set aside to cool.
- In a large bowl, combine the eggs, milk, and heavy cream. Whisk to combine and break up the eggs.
- Add ½ tsp salt, ½ tsp black pepper, and mustard. Whisk to combine.
To assemble
- In the prepared shell, evenly add the prepared bacon, cheese, and onion and mushroom mixture.
- Pour the egg mixture over the top.
- Add some grated Parmesan cheese and bake until the quiche is puffed and golden, 25 minutes.
- Cool for 10 minutes before removing from the tart pan and cutting. Slice and enjoy.
