A quiche can either be quick and easy to make, or somewhat of an involved process. The quick and easy way? Use a frozen pie crust. The longer way? Make your crust from scratch. In my opinion, nothing beats a homemade butter crust. But not everyone has the time for that, so don’t let making a crust stop you from making a quiche, it’s easy!
This mushroom quiche recipe is slightly adapted from one we found in a 2002 issue of Martha Stewart magazine. I’ve changed it with my own version of blind baking the crust, and I’ve simplified the instructions a bit. It’s a straightforward recipe. You blind bake (pre-bake) a frozen crust, sauté chopped mushrooms and shallots, line the crust with Gruyere and the cooked mushrooms, fill in with an egg cream milk mixture and bake until golden.
Mushrooms need to be sautéed first, not only for the flavor, but because they have so much water with them that releases when they cook, that if you bake with raw mushrooms, you’ll end up with a soggy quiche.
Whenever a recipe calls for mushrooms, I like to include some shiitakes in the mix. They are more expensive than regular mushrooms, but you only need a few. Their flavor is so intense, they elevate any mushroom dish.
This recipe includes instructions for making the quiche crust. You can easily use an already made, frozen pie crust. If you are using a frozen pie crust, don't defrost it, just proceed to step 2.
- 1 recipe pie dough enough for one bottom crust (see Pâte Brisée recipe)
- 2 Tbsp olive oil
- 1/3 cup thinly sliced shallots
- 1 pound assorted mushrooms, quartered or sliced (include some shiitakes if you want great mushroom flavor)
- Kosher salt
- Freshly ground pepper
- 1/2 cup milk
- 1/2 cup heavy cream
- 3 large eggs
- Pinch nutmeg
- 6 ounces Gruyère cheese, grated (1 1/2 cups)
1 Roll out dough on a clean, lightly floured surface into a 12-inch circle. Line a 10 by 1 1/2-inch tart pan with the rolled out dough. Trim the edges. Chill in freezer for 30 minutes. (You need to pre-freeze the raw crust or it will slip down the sides of the pan when it cooks.)
At this point, if you are using a pre-frozen pie crust proceed to step 2.
2 Preheat oven to 350°F. Line the crust with aluminum foil or parchment paper, pushing into the bottom edge. Don't cut the foil or parchment paper too close to the crust, allow for enough room to easily lift it out. Fill it at least two-thirds with baking weights—dried beans (I keep a bag of pinto beans just to use for pie weights), rice, or aluminum pie weights.
Bake first for 15 minutes, remove from oven and let cool a few minutes. Carefully remove parchment paper and weights. Poke the bottom of the pie pan with the tines of a fork and return to oven and bake an additional 10 minutes or until lightly golden. (Fork holes are for any air to escape.) Let cool on a rack while you make the filling.
3 Heat oil in a large nonstick skillet over medium high heat. Sauté the shallots for a minute, then add the mushrooms. Sprinkle with salt and pepper and cook, stirring frequently, until the mushrooms release all of their moisture, and get well browned, about 10 minutes.
4 Place the tart pan on a rimmed baking sheet to catch any run-off or leaks. Sprinkle half of the grated Gruyere over the bottom of the crust. Spread the mushrooms and shallots over the cheese in an even layer, and sprinkle with the remaining cheese.
5 Whisk together the cream, milk, and eggs in a medium bowl. Stir in nutmeg, salt and pepper. Pour the egg mixture over the mushrooms and cheese in the crust.
6 Put the baking sheet with the tart pan in the oven and bake at 350°F until the center is just set, still a little wiggly, about 30 to 35 minutes.
Remove to a rack and let cool for 20 minutes before slicing.
