- Servings: 8
1 pie crust, par-baked if you have the patience for it (I made this latest one with a half whole-wheat rough puff pastry)
2 tablespoons butter, plus a few thinly-sliced pats for dotting the top
1 large leek, or 2 small, washed and thinly sliced
1 tablespoon high-heat oil, such as grapeseed
1 pound mushrooms, cleaned and thinly sliced
1/4 pound Swiss cheese, grated (you can substitute gruyere or emmental)
4 ounces goat cheese, crumbled into big hunks
2 cups milk or half-and-half
2 egg yolks
3 whole eggs
1/2 teaspoon salt
pinch white pepper
pinch grated nutmeg
handful chives, minced (optional)
Melt the butter in a large saute pan or cast-iron skillet over a medium flame. Saute the leeks until well softened, but not browned, ~10 minutes (adjust heat as needed). Transfer to a small bowl, and set aside.
Raise the heat in the pan to high, and add the oil. When hot, add the mushrooms — you don't want it to be more than a generous layer or so deep, so you made to do this in batches. Salt lightly, and cook without moving until the liquid comes out and then evaporates (a few minutes). Stir, and cook the other sides until done. Repeat with remaining mushrooms and additional oil, if needed. These steps can be done in advance.
When you're ready to assemble your quiche, preheat your oven to 350° Fahrenheit. Take your (possibly par-baked) crust, and scatter the grated cheese over it. Add the leeks and mushrooms, then top with the goat cheese. You can leave as is, or tumble it up a bit.
In a large bowl, mix together the milk or half and half, eggs and egg yolks, nutmeg, salt and pepper, and chives, if using. Whisk gently, so that the mixture is combined but not frothy. Pour this custard mixture into the quiche shell (depending on its depth, you may not need all of it). Scatter the butter over the top.
Carefully place the quiche in the oven, and bake until only the center inch or so wiggles when you nudge it (about an hour). Remove from the oven, and let set a bit before serving.
