One of my favorite parts is the way the cheese transforms the dish If you use sharp cheddar it adds a tangy bite that perfectly balances the creamy sauce My kids love to help with the final cheese sprinkle before dinner

Storage Tips

Leftovers store well in an airtight container in the refrigerator for up to four days Gently reheat individual portions in the microwave or on the stovetop If you want to freeze let the casserole cool completely then store in portions When reheating from frozen add a splash of milk to restore creaminess

Ingredient Substitutions

No kidney beans Try pinto or black beans Instead of ground beef ground turkey or chicken works well too If you want to skip the condensed soup use a homemade white sauce with mushrooms and a little stock Add bell peppers or green beans for more vegetables
