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)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish with olive oil or butter.

Step 2

In a large mixing bowl, whisk together the eggs, milk, salt, black pepper, and paprika until well combined.

Step 3

Stir in the shredded cheese (reserving a small handful for topping), breakfast sausage, bacon, ham, bell peppers, onion, mushrooms, and spinach.

Step 4

If using bread, fold in the cubed bread to soak up the egg mixture.

Step 5

Pour the mixture evenly into the greased baking dish and spread it out with a spoon or spatula to ensure everything is evenly distributed.

Step 6

Sprinkle the reserved shredded cheese on top for a golden, bubbly finish.

Step 7

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.

Step 8

Remove from the oven and let the casserole rest for 5-10 minutes before slicing into portions.

Step 9

Serve warm and enjoy! Leftovers can be stored in the refrigerator for up to 4 days and reheated as needed.
