Best 3 Leek Gruyere Quiche Recipes

ASPARAGUS, LEEK, AND GRUYERE QUICHE

Steps:

• Preheat oven to 350 degrees, with rack in lowest position. In a large skillet, melt butter over medium. Add leek and asparagus; season with salt and pepper. Cook, stirring occasionally, until asparagus is crisp-tender, 6 to 8 minutes; let cool.
• In a large bowl, whisk together eggs, half-and-half, 1/2 teaspoon salt, teaspoon pepper, and a pinch of nutmeg. Place pie crust on a rimmed baking sheet. Sprinkle with cheese; top with asparagus mixture. Pour egg mixture on top.
• Bake until center of quiche is just set, 50 to 60 minutes, rotating sheet halfway through. Let stand 15 minutes before serving.

HAM, LEEK AND GRUYERE QUICHE

Steps:

• For the crust: Preheat the oven to 375 degrees F. Pulse together the flour and salt in a food processor. Add the chilled butter and pulse just until the butter is evenly distributed throughout. Add the sour cream and continue to pulse 2 to 4 more times until just incorporated. Add 2 tablespoons of ice water at a time, pulsing after each addition, until the dough starts to hold together. Add more water as needed. Turn the dough out onto plastic wrap and form it into a disc. Wrap the dough in the plastic wrap and let rest in the refrigerator 30 minutes. Roll the dough on a floured surface into a 12-inch circle about 1/4-inch thick. Roll up the dough using a rolling pin, and gently lift and place it over a deep, 10-inch tart pan. Gently press the dough into all the crevices and trim the overhang to 1/2-inch. Crimp the edges for a decorative finish and use the trimmed dough to patch any holes. Dock the bottom of the crust with a fork to keep it from puffing up, line with parchment paper and add dried beans to act as pie weights. Place on a large baking sheet and bake until the crust begins to brown, 20 to 30 minutes. Remove the parchment and dried beans. For the custard: Melt the butter in a large saute pan over medium heat and saute the leeks until they soften and begin to caramelize, stirring occasionally, 8 to 10 minutes. Remove from the heat, cool and reserve. Whisk the cream, milk, cornstarch, salt, pepper, cayenne, nutmeg and eggs in a large mixing bowl. Scatter the leeks evenly over the bottom of the crust. Top with the cheese and ham. Pour the custard over the top and place in the oven on a large sheet tray. Bake until the center is set and the crust is golden brown, 40 to 45 minutes. Let cool on a wire rack. Serve warm or at room temperature.

LEEK GRUYERE QUICHE

Steps:

• Combine flour, butter, 1 egg, and salt in a bowl. Knead together with your hands, adding as much water as needed, in small amounts, to create a smooth dough. Shape dough into a ball, flatten, and wrap in plastic wrap. Refrigerate for at least 30 minutes.
• Preheat the oven to 400 degrees F (200 degrees C). Grease a 10-inch springform pan.
• Heat olive oil in a skillet and cook leeks over medium heat until translucent, about 5 minutes.
• Remove dough from fridge. Dust a work surface with flour and roll out dough into a circle about 1 inch larger than the springform pan. Fold carefully in half, lift up, and unfold over the pan. Press over the bottom and 1 inch up the sides.
• Whisk 4 eggs and creme fraiche in a bowl. Stir in leeks, Gruyere cheese, Emmentaler cheese, and ham. Season with white pepper and nutmeg. Pour over the crust and spread evenly with the back of a spoon.
• Bake in the preheated oven until filling is set, about 30 minutes.
