In a medium-sized skillet, cook the Italian sausage over medium heat until browned and fully cooked, breaking it into small pieces as it cooks. Drain any excess fat and set aside to cool slightly.
Lightly grease a 9x13-inch baking dish. Spread the cubed bread evenly in the dish.
Sprinkle the cooked sausage over the bread cubes, followed by the shredded cheddar cheese.
In a large mixing bowl, whisk together the milk, eggs, Dijon mustard, salt, and black pepper until fully combined.
Pour the egg mixture evenly over the bread, sausage, and cheese in the baking dish. Use a spatula to press the bread down slightly, ensuring all pieces absorb the liquid.
Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
When ready to bake, preheat the oven to 350°F (175°C). Remove the dish from the refrigerator and allow it to sit at room temperature for 20 minutes while the oven preheats.
Bake the casserole, uncovered, for 45-50 minutes or until the top is golden brown and the casserole is set. A knife inserted into the center should come out clean.
Remove the casserole from the oven and let it rest for 5-10 minutes before serving.
Garnish with chopped parsley, if desired, and enjoy!
