Why You’ll Love This Slow Cooker Cowboy Casserole

This casserole hits every comfort food note. The slow cooker does all the work, and you end up with a satisfying, protein-rich dish that warms you from the inside out. It’s also flexible—you can spice it up with jalapeños, add extra veggies, or top it with your favorite cheese blend.

Plus, it stores and reheats like a dream. It’s great for batch cooking, potlucks, or those evenings when you just need something cozy and reliable.

What Kind of Potatoes Should I Use?

Russet potatoes are the classic pick here because they hold their shape well during slow cooking and soak up the savory broth like champs. But Yukon Golds work beautifully too, offering a buttery texture that melds seamlessly with the meaty, cheesy sauce.

Ingredients for the Slow Cooker Cowboy Casserole

Each ingredient in this cowboy casserole serves a purpose in building that hearty, cozy flavor:

Corn Kernels: A sweet pop of texture in each spoonful.
Diced Tomatoes: Brings acidity and moisture.
Yellow Onion: Adds subtle sweetness and depth.
Minced Garlic: For bold flavor.

How To Make the Slow Cooker Cowboy Casserole

Step 1: Brown the Beef

Heat a skillet over medium heat, add your ground beef, and cook until browned. Drain excess grease and set aside.

Step 2: Layer the Ingredients

In your slow cooker, layer half the potatoes on the bottom, followed by half the browned beef, beans, corn, diced tomatoes, onions, and garlic. Repeat the layers.

Step 3: Season and Pour

Sprinkle in salt, pepper, and paprika. Pour the beef broth evenly over the mixture.

Step 4: Slow Cook

Cover and cook on low for 7-8 hours or high for 4-5 hours, until the potatoes are fork-tender.

Step 5: Add the Cheese

About 10 minutes before serving, sprinkle shredded cheddar cheese over the top and cover again to melt.

Serving and Storing Cowboy Casserole

This recipe makes a generous 6 servings, making it perfect for a hungry family or a round of weekday meal prep.

Serve hot straight from the slow cooker, with a sprinkle of parsley or some sour cream on top. Any leftovers can be stored in an airtight container in the fridge for up to 4 days. You can also freeze it for up to 2 months—just reheat in the microwave or stovetop and stir gently to recombine the textures.
