2 2/3 c. whole milk
1 1/2 teaspoons kosher salt
1 1/2 teaspoons ground dry mustard
1 teaspoon dried parsley
1/4 teaspoon black pepper
1/4 teaspoon paprika

How to make Loaded Overnight Breakfast Casserole

Step 1: Brown the sausage in a large skillet, crumbling the meat as it cooks. When done, drain the grease and set the sausage aside.

Step 2: Into half-inch pieces, cube the Italian bread using a bread knife. Set aside.

Step 3: Mix the shredded cheddar and Gruyere cheeses and set them aside.

Step 4: Whisk the eggs, milk, salt, dry mustard, dried parsley, black pepper, and paprika in a large bowl until well mixed.

Step 5: To the bottom of a 3-quart oven-safe pot or 9 x 13-inch baking pan, add the cubed pieces of bread, top with the crumbled sausage, then bacon, and 3/4 of the cheeses. Then, over the bread, crumbled sausage, and bacon, pour the egg custard, pushing gently any un-soaked bread down using a wooden spoon into the custard and sprinkle over the rest of the shredded cheeses.

Step 6: Using foil, cover the pan and place it in the fridge overnight.

Step 7: The next day, take the casserole out of the oven, remove the cover, and let it come to room temperature while the oven is preheating to 350 degrees F. Then, bake for approximately 40 to 45 minutes until a toothpick inserted in the middle of the casserole comes out clean.

Step 8: Remove from the oven when done, garnish if desired, and serve hot. Enjoy!
