01 - Preheat oven to 400°F (200°C).
02 - In a mixing bowl, blend thawed hashbrowns with melted butter. Firmly press the mixture into the bottom and sides of a 9-inch pie plate to create an even crust.
03 - Place the pie plate in the preheated oven. Bake for 20 minutes, or until edges turn golden brown and crisp.
04 - While crust is baking, whisk together eggs, half-and-half, salt, black pepper, garlic powder, and onion powder in a separate bowl until well combined.
05 - Once the crust is baked, sprinkle shredded cheddar cheese and crumbled bacon evenly over the crust surface.
06 - Pour the egg mixture slowly and evenly over the bacon and cheese.
07 - Reduce oven temperature to 350°F (175°C). Bake for 30 to 35 minutes, or until the center is set and the top is golden brown.
08 - Allow quiche to rest for several minutes before slicing and serving.
