# Directions:

01 - Preheat the oven to 350°F. Grease a 9x13-inch baking dish with butter or nonstick spray.
02 - In a large skillet over medium heat, cook the sausage, breaking it up with a spoon, until browned and cooked through, about 5–7 minutes. Add onion and bell pepper if using; sauté until softened, 3–4 minutes. Drain excess fat.
03 - Spread the bread cubes evenly in the prepared baking dish. Top with the cooked sausage and vegetables.
04 - In a large bowl, whisk together the eggs, milk, salt, pepper, mustard powder, and paprika until well combined.
05 - Stir in 1 1/2 cups cheddar cheese and all the mozzarella until evenly distributed.
06 - Pour the egg mixture evenly over the bread and sausage in the baking dish. Gently press the bread down so it soaks up the liquid.
07 - Sprinkle remaining cheddar cheese evenly over the top of the casserole.
08 - Cover with foil and bake for 30 minutes.
09 - Remove foil and bake another 15 minutes until golden and set in the center. Let rest for 10 minutes before slicing and serving.
