Prep/Cooking Time: 10 Hrs
1 pound pork sausage
6 (1 ounce) slices bread, cubed
2 cups shredded Cheddar cheese
2 cups milk
1 teaspoon salt
1 teaspoon ground dry mustard
Place sausage in a large, deep skillet. Cook over medium-high heat until evenly brown. Drain, and set aside.
Layer bread cubes, sausage, and Cheddar cheese in a lightly greased 7×11 inch baking dish. In a bowl, beat together the eggs, milk, salt, and mustard. Pour the egg mixture over the bread cube mixture. Cover, and refrigerate at least 8 hours or overnight.
Remove the casserole from the refrigerator 30 minutes before baking. Preheat oven to 350 degrees F (175 degrees C).
Bake 50 to 60 minutes in the preheated oven, or until a knife inserted in the center comes out clean. Let stand 10 minutes before serving.
