Ingredients Notes

The beauty of this Slow Cooker Cowboy Casserole is in its simple ingredients, each adding its own special touch to the dish. Let’s take a closer look:

Ground beef – I prefer using 80/20 ground beef for the best flavor and texture. If you want a leaner option, you can swap it for ground turkey or chicken.
Potatoes – Russet potatoes work best because they hold their shape and soak up all the flavors. If you prefer a creamier texture, Yukon Gold potatoes are another great option.
Beans – Traditional cowboy casseroles often use kidney beans or pinto beans for heartiness. If you like variety, black beans or white beans work just as well.
Diced tomatoes with green chilies – These add a subtle heat and tangy depth to the dish. If you want a milder version, regular diced tomatoes will do.
Cheese – Sharp cheddar melts beautifully and gives the casserole a rich, creamy finish. You can also mix in Monterey Jack or Pepper Jack for extra kick.
Cream of mushroom soup – This helps create a thick, creamy sauce that ties everything together. If you’re not a fan, cream of chicken or cream of cheddar soup works too.
Seasonings – A simple blend of garlic powder, onion powder, smoked paprika, and black pepper enhances the dish without overpowering it.

You’ll also need a slow cooker (at least 6 quarts) to fit all these delicious layers!

How to Make This Slow Cooker Cowboy Casserole

This recipe couldn’t be easier! Just follow these simple steps, and your Slow Cooker Cowboy Casserole will be ready to enjoy with minimal effort.

Brown the beef – In a skillet over medium heat, cook the ground beef until it’s no longer pink. Drain any excess grease and season with garlic powder, onion powder, paprika, salt, and pepper for extra flavor.
Layer the ingredients – In your slow cooker, start with a layer of sliced potatoes, followed by ground beef, beans, and diced tomatoes. Repeat the layers until everything is used up.
Add the creamy sauce – Pour the cream of mushroom soup over the top, then spread it evenly with a spoon. This will help everything cook together and stay moist.
Slow cook to perfection – Cover and cook on low for 6-7 hours or high for 3-4 hours, until the potatoes are fork-tender.
Finish with cheese – In the last 20 minutes, sprinkle shredded cheddar cheese on top, cover again, and let it melt into the casserole.
Serve and enjoy – Once everything is hot and bubbly, scoop out hearty servings and enjoy with a side of crusty bread or a fresh green salad.

From start to finish, you’ll get a rich, comforting dish that’s loaded with flavor.
