Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter and set aside.
In a large skillet over medium heat, cook the ground breakfast sausage until browned and fully cooked, breaking it up with a wooden spoon as it cooks. Drain any excess fat and set aside.
Cut the bread slices into 1-inch cubes and spread them evenly in the greased baking dish.
Evenly distribute the cooked sausage over the bread cubes. Sprinkle the shredded cheddar cheese on top.
In a large mixing bowl, whisk together the eggs, milk, Dijon mustard, salt, and black pepper until well combined. Add the optional sliced green onions if desired.
Pour the egg mixture evenly over the bread, sausage, and cheese, ensuring that all the bread is saturated.
Cover the dish with aluminum foil and let it sit in the refrigerator for at least 30 minutes, or overnight if preparing ahead of time.
Bake the covered casserole in the preheated oven for 30 minutes. Then remove the foil and bake for an additional 20 minutes, or until the top is golden brown and the casserole is set in the center.
Remove the casserole from the oven and let it cool for 5-10 minutes before serving. Slice into squares and enjoy!
