Ingredients

• 1 pound Italian sausage
• 6 Eggs
• 2 cups Whole milk
• 1.5 cups Cheddar cheese, shredded
• 6 cups Day-old bread, cubed
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Ground mustard
• 3 Scallions, sliced (optional)
• 1 tablespoon Butter or non-stick spray for greasing

Directions

Step 1

Grease a 9x13-inch baking dish with butter or non-stick spray.

Step 2

In a skillet over medium heat, cook the Italian sausage until browned and fully cooked through, breaking it into small chunks with a spatula. Drain any excess grease and set aside to cool slightly.

Step 3

In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and ground mustard until fully combined.

Step 4

Add the cubed bread to the egg mixture and stir gently to coat. Allow the bread to soak for 5 minutes.

Step 5

Stir in the cooked sausage, 1 cup of shredded cheese, and optional scallions. Mix until evenly distributed.

Step 6

Pour the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining 0.5 cup of shredded cheese on top.

Step 7

Cover the dish tightly with plastic wrap or aluminum foil and refrigerate for at least 8 hours or overnight.

Step 8

The next morning, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and allow it to sit at room temperature while the oven preheats.

Step 9

Bake the casserole uncovered for 45-50 minutes, or until puffed and golden brown on top, and a knife inserted into the center comes out clean.

Step 10

Let the casserole cool for 5-10 minutes before slicing and serving. Enjoy your warm, savory breakfast!
