Description
Prepare this impressive, gourmet quiche featuring a flaky all-butter crust, sweet caramelized onions, savory Gruyère cheese, and fresh spinach for a special Mother’s Day brunch centerpiece.
Ingredients
Scale
- 1 recipe all-butter pie crust (9-inch)
- 1 tablespoon olive oil
- 2 large yellow onions, thinly sliced
- 1/4 teaspoon salt
- 1/8 teaspoon black pepper
- 4 ounces fresh spinach, roughly chopped
- 1 cup shredded Gruyère cheese
- 3 large eggs
- 1 cup heavy cream
- 1/2 teaspoon Dijon mustard
- Pinch of nutmeg
Instructions
- Prepare the pie crust and press it into a 9-inch pie dish. Chill the crust while you prepare the filling.
- Heat the olive oil in a skillet over medium-low heat. Add the sliced onions, salt, and pepper. Cook slowly, stirring occasionally, for 25 to 35 minutes until the onions are deep golden brown and sweet. Remove from heat and set aside.
- Preheat your oven to 375°F (190°C).
- Spread the chopped spinach evenly over the bottom of the chilled pie crust. Top the spinach with the caramelized onions, followed by the shredded Gruyère cheese.
- In a medium bowl, whisk together the eggs, heavy cream, Dijon mustard, and nutmeg until well combined.
- Carefully pour the egg mixture over the cheese and onion layers in the crust.
- Bake for 40 to 50 minutes, or until the center is set and a knife inserted near the edge comes out clean. The top should be golden brown.
- Let the quiche cool on a wire rack for at least 15 minutes before slicing and serving.
Notes
- For the flakiest crust, keep all ingredients very cold when making the pastry.
- You can caramelize the onions a day ahead to save time on the day of brunch.
- If the crust edges brown too quickly during baking, cover them loosely with aluminum foil strips.
