How to Make Overnight Mushroom Souffle

  1. Saute 8 oz cremini mushrooms in 1 tablespoon butter over medium heat until softened. Set aside.
  2. In the same pan, saute 1/2 cup chopped celery, 1/2 cup chopped onion, and 1/2 cup chopped green bell pepper in 1 tablespoon butter until tender-crisp.
  3. While vegetables cook, butter 6 slices of bread (about 1/2 loaf) and cut into 1-inch cubes.
  4. Spread the buttered bread cubes evenly in a greased 9x13 inch baking pan.
  5. Combine the sauteed mushrooms and vegetables with 1/2 cup mayonnaise, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
  6. Spread the mushroom and vegetable mixture over the bread in the pan.
  7. Cube 4 unbuttered slices of bread (about 1/3 loaf) and sprinkle evenly over the vegetable mixture.
  8. In a bowl, whisk together 4 large eggs and 1 cup milk.
  9. Pour the egg mixture evenly over the second layer of bread.
  10. Cover the pan tightly with plastic wrap and chill in the refrigerator overnight.
  11. The next day, preheat oven to 325°F (160°C).
  12. Spread 1 cup of your favorite mushroom soup evenly over the chilled mixture.
  13. Butter 4 slices of bread (about 1/3 loaf), cube, and sprinkle over the soup.
  14. Sprinkle 1 cup of shredded cheddar cheese (or your preferred cheese) over the top layer of bread.
  15. Bake for 1 hour, or until golden brown and bubbly. Cover loosely with foil for the last 30 minutes of baking if the cheese is browning too quickly.
