I don't know where this casserole originated, but the recipe was given to me some 40 years ago. It's my family's all-time favorite. Not only is it a great "company" meal, it's also well-received at potluck dinners. —Johnie Mae Barber, Oklahoma City, Oklahoma

  • 8 slices day-old white bread
  • 4 cups chopped cooked chicken
  • 1 jar (4-1/2 ounces) sliced mushrooms, drained
  • 1 can (8 ounces) sliced water chestnuts, drained
  • 4 large eggs, lightly beaten
  • 2 cups whole milk
  • 1/2 cup mayonnaise

  1. Remove the crusts from bread and set aside. Arrange bread slices in a greased 13x9-in. baking dish. Top with chicken; cover with the mushrooms and water chestnuts.
  2. In a large bowl, whisk the eggs, milk, mayonnaise and salt. Pour over chicken. Arrange cheese on top. Combine soups and pimientos; pour over cheese. Cover and refrigerate overnight.
