This quiche is a personal favorite. It’s loaded up with thick-cut ham, melty Gruyère, and sweet sautéed onions. So simple, so classic, and always a hit.
*Note that you will change the oven temperature 3 times. These are bolded in the recipe below.
1 (9-inch) single-crust homemade pie crust, our recipe makes enough for 2 quiches, see tips
8-ounce ham steak, ½-inch thick, cut into ½-inch cubes (226 g)
1 medium onion, thinly sliced into half moons
3 tablespoons butter
5 large eggs, plus 1 egg for egg wash
1 cup heavy cream (236 ml)
1 ¼ teaspoons Dijon mustard
⅛ teaspoon sweet paprika
⅛ teaspoon fresh ground black pepper
½ teaspoon fine sea salt
2 tablespoons white wine or substitute water, see tips
2 tablespoons water
4 ounces Gruyère cheese, shredded, 1 packed cup (113 g)
1Prepare crust: Lightly grease a 9-inch pie plate (pie dish). Roll out the dough to be two inches larger than your pie dish (I use an 8-inch or 9-inch pie dish). Gently press the dough down into the dish to line the bottom and sides. Be careful not to pull or stretch the dough. Fold the edges of the dough underneath itself, creating a thicker, ¼-inch border that rests on the lip of the dish. Crimp edges. (We do this in our pie crust recipe video.)
2Chill the crust: Pierce the bottom of the crust all over with a fork. Refrigerate for 20 to 30 minutes.
3Preheat the oven: While the unbaked pie crust chills, preheat the oven to 425°F (220°C). Place a baking sheet on a middle oven rack.
4Bake the crust: Crumple up a sheet of parchment paper in your hands, then uncrumple it and use it to line the crust (or use foil). Fill with pie weights, dried rice, or dried beans. Place the pie crust on the preheated baking sheet and reduce the oven temperature to 400°F (200°C). Bake for 20 minutes or until the crust is light golden brown. Remove the rice, beans, pie weights, and parchment from the pie crust.
5Make egg wash: Whisk one egg with 1 tablespoon of water in a small bowl. Brush the bottom and sides of the crust with egg wash. Bake until the egg wash is dry, 3 to 5 minutes.
6Prepare the filling: Heat 1 tablespoon of the butter in a large skillet over medium heat. Add the diced ham, and cook until lightly browned, about 4 minutes.
7Transfer the ham to a bowl, then add the remaining 2 tablespoons of butter to the skillet. Add the onions and cook, stirring often, until lightly browned, about 8 minutes. Pour in the white wine and water and deglaze the pan. Cook until all of the liquid is gone, then turn off the heat.
8Make the egg mixture: Whisk the remaining 5 eggs, heavy cream, Dijon mustard, paprika, pepper, and salt in a bowl.
9Assemble: Spread the ham, onions, and cheese in the pie crust. Pour the egg mixture over them, and then shimmy the pie dish to remove any air bubbles.
10Bake: Now, reduce the oven temperature to 325°F (162°C), then bake until the egg sets and the crust turns a light golden brown, about 55 to 65 minutes, turning once halfway. Remove from the oven and cool on a wire rack for 10 to 15 minutes before cutting.
