Ingredients

  • 9 frozen hash brown patties
  • 1 cup diced ham
  • ½ cup diced red bell pepper

  • ½ cup diced yellow onion
  • 2 cups shredded Monterey Jack and cheddar cheese blend
  • 5 large eggs
  • 2 cups milk
  • 1 teaspoon salt

Instructions

  • Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick cooking spray.

  • In a large mixing bowl, whisk together the eggs, milk, salt, garlic powder, and black pepper until fully combined.
  • Carefully pour the egg mixture over the layered ingredients in the baking dish, ensuring even coverage.
  • Cover the baking dish with aluminum foil and bake for 30 minutes.
  • Remove the foil and continue baking for an additional 15 to 20 minutes, or until the eggs are fully set and the casserole is lightly golden around the edges.
  • Remove from the oven and allow the casserole to rest for 5 minutes before slicing and serving.
