Recipe Information
Ingredients
- 10 large eggs
- 1.25 cups milk
- 2 cups shredded cheese (cheddar, mozzarella, or a blend)
- 1 cup cooked breakfast sausage, crumbled
- 1 cup cooked bacon, crumbled
- 1 cup diced ham
- 1 cup diced bell peppers (any color)
- 0.5 cup diced onion
- 0.5 cup diced mushrooms
- 1 cup baby spinach
- 3 cups day-old bread, cubed (optional)
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 teaspoon paprika
- 1 tablespoon olive oil or butter (for greasing the dish)
Instructions
Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish with olive oil or butter.
In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and paprika until well combined.
Stir in the shredded cheese (reserving a small handful for topping), breakfast sausage, bacon, ham, bell peppers, onion, mushrooms, and spinach.
If using bread, fold in the cubed bread to soak up the egg mixture.
Pour the mixture evenly into the greased baking dish and spread it out with a spoon or spatula to ensure everything is evenly distributed.
Sprinkle the reserved shredded cheese on top for a golden, bubbly finish.
Bake in the preheated oven for 40-45 minutes, or until the top is golden and the center is set. You can test doneness by inserting a knife into the middle; it should come out clean.
Remove from the oven and let the casserole rest for 5-10 minutes before slicing into portions.
Serve warm and enjoy! Leftovers can be stored in the refrigerator for up to 4 days and reheated as needed.
