Bacon Cheeseburger Quiche
The night before, layer bacon between paper towels on a plate and microwave for 3 to 5 minutes, until crisp. Set aside. Heat oven to 350°. Fit crust into a 9-inch deep-dish pie plate and line crust with foil, pressing down. Bake at 350° for 10 minutes. Remove foil and bake 15 minutes more, until crust holds its shape but small bubbles form. Cool on a wire rack, then cover and store at room temperature overnight.Advertisement
Meanwhile, heat a large nonstick skillet over medium-high heat. Crumble in ground sirloin and add onion and Worcestershire sauce. Cook for 5 minutes. Stir in spinach, crumbled bacon and tomato. Cook for 3 minutes and add salt and pepper. Spoon into a lidded container, cover and refrigerate.
The next day, heat oven to 350°. Break filling apart and spoon into piecrust. In a bowl, whisk together eggs, egg whites, milk, ketchup and mustard. Sprinkle cheese over filling in piecrust. Pour in egg mixture and transfer to oven. Bake at 350° for 1 hour, 10 minutes, until a toothpick inserted in center comes out clean. Cover edge with foil if it’s browning too quickly. Cool 10 minutes before slicing. Serve with salad alongside, if desired.
