Cowboy Quiche is the ultimate hearty, satisfying breakfast that brings classic comfort to the table. It is filled with smoky bacon, caramelized onions, and cheddar cheese, all baked together in a buttery pie crust. It’s rich, savory, and packed with bold flavor.
Cook the 4 cups diced onion, and 2 tablespoons unsalted butter in a large skillet over low heat for 25-30 minutes, stirring occasionally, until the onions are fragrant and golden brown. If you prefer your onions to be even more caramelized, you can continue to cook them for an additional 25-30 minutes.
Preheat the oven to 350 degrees Fahrenheit and press 1 (9-inch) pie crust, into a 9-inch pie pan. Keep the pie crust chilled in the refrigerator until you are ready to fill it.
In a large bowl, whisk together 7 large eggs, 1 cup milk, ⅓ cup heavy cream, 1 teaspoon salt, ½ teaspoon ground black pepper, and ½ teaspoon garlic powder.
Add the onions, 10 cooked bacon strips, and 1 ½ cups shredded cheddar cheese to the bottom of the pie crust, and then pour the egg mixture over the top.
Bake for 35-40 minutes, until the top is browned and the eggs are set. Let the quiche cool for 15-20 minutes before serving.
