Description

This Cowboy Quiche is a hearty and flavorful dish featuring caramelized onions, crispy bacon, and sharp cheddar cheese baked in a buttery pie crust. Perfect for breakfast, brunch, or a comforting dinner, this quiche combines rich, savory ingredients with a creamy egg custard for a satisfying meal.


Ingredients

Scale

Pie Crust

  • 1 (9-inch) pie crust, homemade or store-bought

Filling

  • 4 cups diced onion (about 2 large onions)
  • 2 tablespoons unsalted butter
  • 7 large eggs
  • 1 cup milk
  • ⅓ cup heavy cream
  • 1 teaspoon salt
  • ½ teaspoon ground black pepper
  • ½ teaspoon garlic powder
  • 10 cooked bacon strips
  • 1 ½ cups shredded cheddar cheese

Instructions

  1. Caramelize the Onions: Cook the diced onions and unsalted butter in a large skillet over low heat for 30 minutes, stirring occasionally, until the onions are golden brown and fragrant. For deeper caramelization, continue cooking for an additional 25-30 minutes if desired.
  2. Prepare the Pie Crust: Preheat the oven to 350 degrees Fahrenheit. Press the pie crust into a 9-inch pie pan and keep it chilled in the refrigerator until ready to fill.
  3. Mix the Egg Custard: In a large bowl, whisk together the eggs, milk, heavy cream, salt, ground black pepper, and garlic powder until fully combined.
  4. Assemble the Quiche: Spread the caramelized onions evenly in the bottom of the chilled pie crust. Layer the cooked bacon strips over the onions, then sprinkle the shredded cheddar cheese on top. Pour the egg mixture over all the fillings gently to avoid displacement.
  5. Bake the Quiche: Place the quiche in the preheated oven and bake for 40 minutes, or until the top is browned and the eggs are fully set. Remove from oven and allow it to cool for 20 minutes before slicing and serving.

Notes

  • You can substitute bacon with smoked sausage or omit for a vegetarian version by using a vegetarian bacon alternative.
  • For a deeper onion flavor, caramelize the onions longer but watch carefully to prevent burning.
  • Make sure the pie crust is cold before baking to ensure a flaky texture.
  • Use sharp cheddar cheese for stronger flavor or mild cheddar for a creamier taste.
  • If you prefer a crustless quiche, bake the filling in a buttered pie dish without the crust but reduce baking time by about 5-10 minutes.
  • Allow the quiche to cool slightly before slicing to ensure clean cuts and the custard sets properly.
