Notes

  • You can substitute cream of celery soup for cream of mushroom soup if you prefer a different flavor base.
  • For extra flavor, add 1/4 cup of chopped celery when mixing the ingredients.
  • If you do not have potato chips, use 1/2 cup of dry breadcrumbs mixed with 1 tablespoon of melted butter for the topping.
