Ingredients
- 1 1/4 cups whole wheat flour
- 1/2 cup all-purpose flour
- 6 tablespoons unsalted butter, cold and cubed
- 1/4 teaspoon sea salt
- 4 to 5 tablespoons ice water
- 2 cups fresh spinach, roughly chopped
- 1 medium red bell pepper, finely diced
- 1 cup mushrooms, thinly sliced
- 4 large eggs
- 1/2 cup plain Greek yogurt
- 1/2 cup low-fat milk
- 3/4 cup sharp cheddar cheese, shredded
- 1/4 cup fresh herbs such as chives and parsley, minced
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder
- 2 tablespoons extra-virgin olive oil
- 1 medium yellow onion, finely diced
Instructions
- 1
Combine whole wheat flour, all-purpose flour, and sea salt in a large mixing bowl.
- 2
Cut the cold butter cubes into the flour mixture using a pastry cutter or your fingertips until the texture resembles coarse breadcrumbs.
- 3
Drizzle ice water over the mixture one tablespoon at a time, stirring gently until the dough just comes together without becoming wet.
- 4
Form the dough into a flat disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
- 5
Preheat your oven to 375°F and position a rack in the lower third of the oven.
- 6
Roll out the chilled dough between two sheets of parchment paper until it's about 1/8 inch thick.
- 7
Transfer the dough to a 9-inch pie dish, pressing it gently into the bottom and sides, then trim any excess from the edges.
- 8
Heat olive oil in a large skillet over medium-high heat and sauté the diced yellow onion until it becomes translucent, about 4 minutes.
- 9
Add the sliced mushrooms to the skillet and cook until they release their moisture and begin to brown, approximately 6 minutes.
- 10
Stir in the chopped spinach and diced bell pepper, cooking until the spinach wilts and the pepper softens, about 3 minutes.
- 11
Remove the vegetable mixture from heat and spread it evenly across the bottom of the prepared pie crust.
- 12
Whisk together the eggs, Greek yogurt, and low-fat milk in a separate bowl until smooth and fully combined.
- 13
Stir in the shredded cheddar cheese, fresh herbs, black pepper, and garlic powder into the egg mixture.
- 14
Pour the custard filling over the vegetables in the crust, ensuring it's distributed evenly.
- 15
Bake in the preheated oven until the filling is set in the center and the edges are lightly golden, about 35 to 40 minutes.
- 16
Allow the quiche to cool for 10 minutes before slicing and serving.
