Christmas Morning Breakfast Casserole - Tahoe Brunch

Butter the bread with the 3 tablespoons softened butter (or melt and brush on) and set aside. In a saute pan, melt the 1/2 cup butter; brown the mushrooms and onions over medium heat for 5 to 8 minutes. Season with salt and pepper, to taste. Set aside to cool. In the same pan, cook the sausage, crumbling into bite-sized pieces. Grease a 13”x9” baking dish and layer half of the bread (enough to cover the entire bottom of the dish), followed by the mushroom mixture, sausage, and cheese. Repeat the layers one more time, ending with the cheese on top. In a bowl, mix the eggs, milk, Dijon mustard, nutmeg, salt, & pepper. Pour over the sausage and cheese casserole. Cover the casserole with tinfoil and refrigerate overnight. Heat oven to 350°. When ready to bake, sprinkle chopped parsley evenly over the top of the casserole. Bake uncovered for 1 hour or until bubbly. Serve Christmas morning and enjoy!
