How to Make Slow Cooker Cowboy Casserole
- Cook the Beef Mixture: In a skillet over medium heat, brown the ground beef with the chopped onion and garlic until the beef is fully cooked and the onions are tender. Drain excess fat.
- Combine in the Slow Cooker: Transfer the beef mixture to 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 until everything is well combined.
- Add the Potatoes: Layer the sliced potatoes on top of the beef mixture, ensuring they’re evenly coated with the sauce.
- Cook: Cover and cook on low for 6-7 hours or on high for 3-4 hours.
- Add the Cheese: About 20 minutes before serving, sprinkle the shredded cheese on top of the casserole and let it melt. Once the cheese is gooey and golden, it’s ready to serve!
Storage Options
Leftovers can be stored in an airtight container in the fridge for 3-4 days. To reheat, simply warm it up on the stovetop or microwave. You can also freeze the casserole for up to 3 months—just thaw it in the fridge overnight before reheating.
Variations and Substitutions
- Meat Choices: Try using ground turkey, chicken, or pork for a lighter meal, or swap in sausage or chorizo for a smoky, spicy flavor.
- Bean Options: Pinto, black, or even baked beans are great alternatives to kidney beans, providing different textures and flavors.
- Potato Substitutes: For a lower-carb option, replace regular potatoes with sweet potatoes, butternut squash, or cauliflower.
- Spicy Kick: If you like heat, toss in jalapeños, chipotle peppers, or a splash of hot sauce to give it some spice. You can also use spicy salsa for an added burst of flavor.

This casserole is great on its own but also pairs well with a variety of sides:
- Salads: A fresh, crisp salad balances the richness of the casserole.
