Ingredients Notes

This Slow Cooker Cowboy Casserole comes together with simple, wholesome ingredients that pack a ton of flavor. Here’s what makes this dish so special:

Ground beef – The heart of this casserole, ground beef adds a rich, meaty flavor. For a leaner option, use ground turkey or chicken.
Potatoes – Yukon Gold or Russet potatoes work best, as they hold their shape while becoming deliciously tender. If you’re short on time, frozen diced potatoes or hash browns make a great substitute.
Diced tomatoes with green chilies – These add a tangy, slightly spicy kick that balances out the richness of the dish. If you prefer a milder taste, use regular diced tomatoes.
Kidney beans – These hearty beans add texture, protein, and a little southwestern flair. You can swap them for black beans or pinto beans if desired.
Corn – Sweet corn kernels provide a pop of sweetness that complements the savory elements perfectly. Frozen, canned, or fresh all work well.
Cream of mushroom soup – This ingredient helps create a thick, creamy sauce that binds everything together. If you’re not a fan, try using cream of chicken soup instead.
Cheddar cheese – Melted on top, it adds a gooey, cheesy layer that ties the casserole together. For extra boldness, use a sharp cheddar or a Mexican cheese blend.
Seasonings – A mix of garlic powder, onion powder, smoked paprika, and black pepper enhances the overall flavor without overpowering the dish.

Special Equipment Needed

All you need for this recipe is a slow cooker (Crockpot) and a large skillet for browning the beef. A sharp knife for slicing the potatoes evenly is also helpful!

How to Make This Slow Cooker Cowboy Casserole

This Slow Cooker Cowboy Casserole comes together in just a few simple steps. Here’s how to make it:

Step 1: Brown the Ground Beef

Start by heating a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it up with a spatula as it cooks. Drain any excess grease, then season with garlic powder, onion powder, smoked paprika, salt, and pepper.

Step 2: Layer the Ingredients

In the bottom of your slow cooker, add a layer of sliced potatoes. Next, spread half of the cooked ground beef over the potatoes, followed by half of the kidney beans, corn, and diced tomatoes with green chilies. Repeat the layers once more.

Step 3: Add the Sauce

In a small bowl, mix the cream of mushroom soup with ½ cup of water or broth to thin it slightly. Pour this mixture evenly over the layered ingredients in the slow cooker.

Step 4: Cook Low and Slow

Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the potatoes are fork-tender. Avoid stirring during cooking to maintain the layered texture.

Step 5: Add the Cheese

About 30 minutes before serving, sprinkle the shredded cheddar cheese on top. Cover and let it melt into gooey perfection.

Step 6: Serve and Enjoy!

Once everything is hot and bubbly, spoon generous portions into bowls and enjoy! Serve with a side of crusty bread or a simple green salad for a complete meal.
