Ingredients

1 1/2 cups walnuts
1 cup all-purpose flour
2 tablespoons sugar
1/2 teaspoon fine salt
5 tablespoons unsalted butter, cut into 1-inch pieces
2 tablespoons olive oil
1 pound mixed wild mushrooms, such as oyster, shiitake and trumpet
3/4 pound white or cremini mushrooms, thinly sliced
Sea salt and freshly ground pepper
2 tablespoons unsalted butter
2 shallots, minced
1 tablespoon chopped thyme
2 1/3 cups freshly grated Parmesan (4 ounces)
1/2 cup shredded Comte or Mahon cheese
3 large eggs
1 1/4 cup heavy cream
2 tablespoons chopped flat-leaf parsley, for garnish
Crisp greens, for serving

Steps:

For the crust: Preheat the oven to 350 degrees F. Pulse together the walnuts, flour, sugar and salt to a fine meal in a food processor. Pulse in the butter until it forms to a crumbly dough. Press into the bottom and up the sides of a 9-inch springform pan. Place on a baking sheet and bake until lightly browned, 15 to 20 minutes. Remove and let cool.
For the filling: Reduce the oven temperature to 325 degrees F. Heat the olive oil in a large skillet over high heat. Add the wild mushrooms and white mushrooms and season with 1 teaspoon salt and some pepper. Cook, stirring occasionally, until soft, about 5 minutes. Lower the heat to medium; add the butter, shallots and thyme. Cook, stirring frequently, until the mushrooms are tender, about 10 minutes more. Adjust the seasoning and set aside.
Combine the Parmesan and Comte cheeses in a small bowl and set aside. Scatter half of the mushrooms and half the cheese evenly over the crust. Whisk the eggs, milk, heavy cream and 3/4 teaspoon salt in a large bowl until smooth and frothy. Pour half the egg mixture over the mushrooms. Repeat with the remaining mushrooms and egg mixture and top with the remaining cheese.
Bake the quiche until golden brown on top and just set with a little wiggle in the very center, 50 to 60 minutes. Run a clean paring knife between the crust and the pan to separate. Let cool slightly for 25 minutes.
Garnish the quiche with parsley. Carefully remove the springform pan ring. Cut the quiche into wedges and serve warm or at room temperature with crisp greens.
