Spring Vegetable Quiche (With Lots of Bacon and Cheese)

We obviously all remember where we were and exactly what day and time it was when we had our first bite of quiche, right? No? Yeah, I guess I don’t remember mine either. I do, however, remember my first bite of truly great quiche. It was at Bouchon Bakery in Napa, about as quiche-y a place as ever there was, and it was spectacular. By virtue of a springform pan, the buttery, flaky, crispy pastry is sculpted neatly around a silky custard, rich with cheese and cured pork, every texture of the texture rainbow on display. Quiche for Sunday brunch is a mild to moderate challenge for the average home cook—memorable quiche, on the other hand, is a prize not easily won. This vegetable quiche recipe is resultantly complicated, but sleep soundly tonight knowing that no matter how fussy a direction might seem, its sole purpose is the success of your quiche. Imagine if that was your sole purpose—you’d want to be taken seriously, wouldn’t you? Did I just guilt-trip you by anthropomorphizing recipe directions? Is that a world-first?

Preparation

  1. Make the Quiche Shell

    Step 1

    In a stand mixer fitted with the paddle attachment, combine the flour and salt. Mix until well combined. Add the butter and mix at medium-low speed until the butter pieces are the size of blueberries. With the mixer running on low speed, slowly add enough of the ice water to form a dough. (Note: To make by hand, whisk the flour and salt in a large bowl. Add the butter and break the pieces into a similar size by rubbing them between your fingers.)

    Step 2

    Wrap the dough in plastic wrap and shape it into a disk. (Note, the dough can also be assembled without a stand mixer, it’s just harder, obviously: Add the cold butter to the flour in a large bowl, and break up the butter with your hands or a pastry cutter until the flour is sandy and the butter pieces are the size of blueberries. Add the ice water and gently knead together by hand until all the flour is hydrated and the dough holds together.) Refrigerate for a minimum of 1 hour, up to overnight.

    Step 3

    Remove the chilled dough from the refrigerator and roll out to about ¼-inch thick. Carefully transfer the dough to an 8-inch high-sided springform pan. Then, gently lift and press the dough into the sides of the pan. If the dough gets too soft, refrigerate for 10 minutes and then resume lining the pan. Make sure the excess dough hangs off the edges of the pan, this will prevent the dough from shrinking during the par-baking process. Once the pie dough is flush with the side of the pan, refrigerate for 1 hour.

    Step 4

    Preheat the oven to 375°F.

    Step 5

    Using two pieces of parchment paper, line the dough in the springform pan. Fill the pan to the rim with sugar or dried beans.

    Step 6

    Par-bake the quiche shell for 25 minutes. Remove the sugar and parchment paper, then continue to bake the shell for 10 to 15 minutes more, until the pastry looks dry and turns pale golden. (Note: Save all that sugar—it’s been toasted in the oven, and has only been improved for future recipe usage!)

    Step 7

    Trim off the excess crust using a sharp paring knife. Allow the quiche shell to cool completely before filling.

  2. Make the Caramelized Leeks and Bacon

    Step 8

    Soak the leeks in a bowl of cold water for 10 minutes, then drain well.

    Step 9

    Heat the oil in a large skillet over medium-high heat. Add the leeks and reduce the heat to medium- low and cover with a lid. Cook, stirring occasionally, until the leeks are very tender, 15 to 20 minutes. Add ¼ cup water, cover, and cook 3 to 5 minutes.

    Step 10

    Uncover and cook until all the water is evaporated, 5 to 10 minutes. Add the bacon and cook, stirring occasionally, until the bacon is crisp, about 5 minutes. Season with pepper, transfer to a plate, and set aside.

  3. Blanche the Asparagus

    Step 11

    Bring a large pot of water to a boil. Add the asparagus and cook until just tender but still bright green, 3 to 4 minutes.

    Step 12

    Meanwhile, prepare a large bowl of ice water.

    Step 13

    Using tongs or a spider, transfer the asparagus to the ice bath and let cool, then drain and set aside.

  4. Make the Sautéed Vegetables

    Step 14

    Melt 1 tablespoon of the butter in a large skillet over medium- high heat. Add the mushrooms, thyme, and ½ teaspoon salt. Cook, stirring occasionally, until the mushrooms have released all of their water and have browned, 7 to 8 minutes. Transfer the mushrooms to a plate and set aside; discard the thyme sprigs.

    Step 15

    Melt the remaining 1 tablespoon butter in the same skillet. Add the spinach and cook, stirring, until completely wilted, 3 to 4 minutes. Add the garlic and cook, stirring, for 1 more minute. Season with salt, transfer to a plate, and set aside.

    Step 16

    Preheat the oven to 325°F.

  5. Make the Custard

    Step 17

    In a large bowl, combine the milk and crème fraîche. Whisk well to incorporate.

    Step 18

    In a stand mixer fitted with the whisk attachment, combine 5 eggs and the flour. Mix at medium-low speed until a paste forms, 1 to 2 minutes.

    Step 19

    Scrape down the sides of the bowl, add the remaining 5 eggs, and the milk mixture. Mix at medium speed until thoroughly combined, about 1 minute. Then add the thyme, white pepper, nutmeg, and 1½ tablespoons salt. Mix on medium speed until the custard is light and frothy, 1 to 2 minutes.

  6. To Assemble

    Step 20

    Line the quiche shell with an even layer of the phyllo dough. (This will help prevent a soggy bottom.) Sprinkle with some of each cheese, then top with an equal amount each of the caramelized leeks and bacon, blanched asparagus, and sauteed vegetables. Add enough of the custard to cover the vegetables. Repeat this layering process with the remaining ingredients, reserving some cheese for topping, until the shell is just about full, stopping 3 to 4 millimeters from the top.

    Step 21

    Sprinkle the quiche with the remaining cheese and bake for 1½ to 2 hours, until the edges are set but the center is still a bit jiggly and the internal temperature reaches 175°F.

    Step 22

    Allow the quiche to cool at room temperature for at least 4 hours before serving. Optionally, once the quiche has cooled to room temperature, refrigerate for up to 3 days before serving.
