Grease a 9x13-inch baking dish with butter or non-stick spray.
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.
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and ground mustard until fully combined.
Add the cubed bread to the egg mixture and stir gently to coat. Allow the bread to soak for 5 minutes.
Stir in the cooked sausage, 1 cup of shredded cheese, and optional scallions. Mix until evenly distributed.
Pour the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining 0.5 cup of shredded cheese on top.
Cover the dish tightly with plastic wrap or aluminum foil and refrigerate for at least 8 hours or overnight.
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.
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.
Let the casserole cool for 5-10 minutes before slicing and serving. Enjoy your warm, savory breakfast!
