A French quiche is one of the simplest dishes you can make and good results are nearly guaranteed… Quiche is a savory baked tart or custard filled with meats, cheese, and vegetables, and thickened with eggs. It is always served open face and baked in a pastry crust, and is regarded as the savory equivalent of a custard tart or pie.
- 1 9-inch refrigerated pie crust
- 2 tablespoons olive oil
- 2 medium onions, chopped
- Kosher salt and black pepper
- 1 cup fresh flat-leaf parsley, chopped
- 4 large eggs
- 3/4 cup half-and-half
- 1/8 teaspoon ground nutmeg
- 8 ounces Gruyere, grated
- 4 cups mixed greens
- Heat oven to 375° F. Fit the crust into a 9-inch pie plate. Place on a baking sheet.
- Heat 1 tablespoon of the oil in a large skillet over medium-low heat. Add the onions and ½ teaspoon each of salt and pepper and cook, stirring occasionally, until soft, 5 to 7 minutes. Stir in the parsley.
- In a large bowl, whisk together the eggs, half-and-half, nutmeg, and ¼ teaspoon salt. Stir in the onion mixture and the Gruyère.
- Pour the egg mixture into the crust. Bake until a knife inserted in the center comes out clean, 35 to 40 minutes. Let sit for 5 minutes. Drizzle the greens with the remaining tablespoon of oil and sprinkle with ¼ teaspoon each salt and pepper. Serve with the quiche.
