How to Make Sausage Mushroom Breakfast Casserole

  1. Cook 1 lb sausage in a large skillet over medium heat until no longer pink, breaking it up with a spoon.
  2. Drain off excess grease.
  3. Add 8 oz sliced mushrooms to the skillet and cook until tender, about 5-7 minutes.
  4. Grease a 3-quart rectangular baking dish. Add 4 cups cubed bread (about 1 loaf) to the dish.
  5. Evenly distribute the sausage and mushroom mixture over the bread cubes.
  6. Sprinkle 1 cup shredded cheddar cheese and 2 tablespoons chopped green onions over the sausage mixture.
  7. In a separate bowl, whisk together 6 large eggs, 1 cup milk, 1/2 cup sour cream, and 1/4 teaspoon black pepper.
  8. Pour the egg mixture evenly over the casserole layers.
  9. Cover the baking dish with plastic wrap and refrigerate for at least 2 hours, or up to 24 hours.
  10. Preheat oven to 325°F (160°C). Bake uncovered for 50-55 minutes, or until a knife inserted near the center comes out clean.
  11. Let the casserole stand for 10 minutes before serving.
