Sausage and Red Onion Sheet Pan Quiche
Sausage and Red Onion Sheet Pan Quiche
Ingredients
Crust
3 ½ cups all-purpose flour (about 14 7/8 ounces),
plus more for work surface
1 tablespoon kosher salt
1 teaspoon black pepper
1 ¼ cups unsalted butter (10 ounces), cut into
1/2-inch pieces and chilled
8 to 10 tablespoons ice water, as needed
Filling
1 tablespoon canola oil
8 ounces bulk breakfast sausage
18 large eggs
2.25 cups half-and-half
1 tablespoon kosher salt
1 ½ teaspoons black pepper
9 ounces Gruyère cheese, shredded (about 2 1/4
cups)
1 small red onion, cut into 1/4-inch rings
2 tablespoons fresh thyme leaves
1 cup loosely packed baby arugula
Directions
Make the crust: Pulse flour, salt, and pepper in a food
processor until combined, about 4 pulses. Scatter butter pieces over flour
mixture; pulse in 1-second bursts until butter is the size of small peas, 9 to
10 pulses. Drizzle ice water into mixture, 1 tablespoon at a time, pulsing
until mixture resembles coarse meal. Turn out onto a work surface; knead just
until dough comes together. Using your hands, flatten into a 1-inch-thick
rectangle. Wrap in plastic wrap, and chill 1 hour.
Line bottom of an 18-x 13-inch rimmed baking sheet with
parchment paper. Unwrap dough, and roll out on a floured work surface into a
20-x 15-inch rectangle. Gently roll dough around rolling pin, and unroll onto
prepared pan. Press dough into corners and up sides of baking sheet. Trim
excess dough to about 1/4 inch above rim of pan. Crimp edges of dough as
desired. Freeze 45 minutes.
Preheat oven to 400°F with rack in upper third of oven. Line
crust with 2 large sheets of parchment paper; top with dried beans or pie
weights to cover. Bake in preheated oven until bottom is set and edges are
light golden brown, 35 to 40 minutes. Remove weights and parchment. Return
crust to oven; bake at 400°F until crisp and browned, 15 to 20 minutes. Gently
press crust down if needed. Let cool completely.
Make the filling: Heat oil in a medium skillet over medium.
Add sausage; cook, breaking into medium-size pieces with a wooden spoon, until
just cooked through, about 6 minutes. Remove from heat.
Whisk eggs in a large bowl until smooth. Whisk in
half-and-half, salt, and pepper. Sprinkle cheese, sausage, and about half of
onion rings over crust. (Reserve remaining onion for another use.) Gently pour
egg mixture over crust; sprinkle with thyme.
Bake at 400°F until slightly puffed and just set, 30 to 35
minutes. Remove from oven; let stand 10 minutes. Top with arugula just before
serving.
