This Slow Cooker Cowboy Casserole is a true comfort meal that only asks for simple ingredients and a few minutes of hands-on prep. Let the slow cooker simmer away while you go about your day, and come home to a cozy, filling dinner with layers of flavor from beef, potatoes, beans, and a lightly spicy tomato sauce topped with melty cheese.
I first made this for a chilly fall evening when my kids had friends over. Now it is our go-to for game days and potlucks because it always disappears fast and everyone leaves happy.
Ingredients
- Ground beef: brings lots of flavor and satisfying protein. Choose one with a bit of fat for taste but not so much you need to drain a lot
- Onion: gives sweetness and depth. A yellow onion works best for richness
- Garlic: brings a punch of savory aroma. Look for firm cloves with tight skins
- Condensed cream of mushroom soup: creates a creamy sauce and binds it all together. Low sodium versions keep it lighter
- Milk: thins the soup for perfect consistency and a silky texture. Whole milk works best
- Kidney beans: add hearty texture and a boost of nutrition. Check for beans that are plump and not broken
- Diced tomatoes with green chilies: provide a tangy kick and extra flavor. Fire roasted tomatoes are especially tasty if available
- Frozen corn: adds bursts of sweetness and color. Use corn that is bright yellow for the best look and taste
- Chili powder: seasons the whole dish with a gentle warmth. Pick a fresh jar for bold flavor
- Salt and black pepper: round out and heighten all the savory notes
- Potatoes: give a tender bite and soak up the sauce. Yukon golds hold up best and become buttery
- Shredded cheese: melts over the top for a gooey finish. Freshly grated cheese has the best melt and flavor
Step-by-Step Instructions
- Brown the Beef and Onion:
- Cook ground beef with chopped onion and minced garlic in a skillet over medium heat. Let it cook until the beef is browned and the onions become soft and translucent. This step develops the deep flavor base and removes excess fat for a less greasy casserole
- Combine in the Slow Cooker:
- Add the cooked beef mixture to your slow cooker. Stir in the condensed cream of mushroom soup milk cooked kidney beans diced tomatoes with green chilies frozen corn chili powder salt and black pepper. Mix thoroughly so everything is evenly combined. This helps the flavors blend into a cohesive sauce as it cooks
- Layer the Potatoes:
- Add the sliced potatoes on top making sure they are fully coated with the beef and bean mixture. Gently press them down to ensure they are just nestled into the liquid. This allows the potatoes to cook evenly and soak up the tasty sauce
- Cook Low and Slow:
- Cover the slow cooker with its lid and cook on low for six to seven hours or on high for three to four hours. The potatoes should be fork tender and all flavors well melded by the end of cooking. Avoid lifting the lid during cooking to keep heat and moisture in
- Finish with Cheese:
- With only twenty minutes left in your cooking time sprinkle shredded cheese evenly over the hot casserole. Replace the lid and let it melt fully for a bubbly cheesy layer on top of the hearty filling
