Step-by-Step Instructions
- Brown the Beef and Aromatics:
- Cook ground beef onion and garlic in a skillet over medium heat Break up the meat as it cooks cooking for about 8 minutes or until beef is fully browned and onions are translucent Drain the fat for a lighter casserole
- Mix Ingredients in the Slow Cooker:
- Combine the browned beef mixture in the insert of your slow cooker Add the cream of mushroom soup milk kidney beans diced tomatoes with green chilies corn chili powder salt and black pepper Stir thoroughly ensuring the seasonings and liquids are evenly incorporated
- Add Potatoes:
- Layer in your sliced potatoes spreading them out so every slice is wellcoated by the sauce and beef mixture This ensures they cook evenly and soak up maximum flavor
- Cook:
- Cover the slow cooker and set to low for 6 to 7 hours or high for 3 to 4 hours Avoid opening the lid too often as this can lower the temperature and extend cooking time The potatoes should be fork tender at the end
- Add Cheese and Finish:
- About 20 minutes before serving sprinkle shredded cheese over the surface Close the lid and allow cheese to melt fully for that irresistible cheesy topping

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
