What Kind of Potatoes Work Best in Cowboy Casserole?

Waxy potatoes like red potatoes or Yukon Golds hold up beautifully in the slow cooker without turning mushy. They cook tender while maintaining their shape, giving your casserole a nice texture. If you only have russets on hand, just cut them into larger chunks to avoid overcooking.

Kidney beans – Boost the fiber and heartiness of the dish.
Corn kernels – Bring in sweetness and color, complementing the savory notes.
Cream of mushroom soup – Adds creaminess and binds everything together.

How To Make the Slow Cooker Cowboy Casserole

Step 1: Brown the Beef

Start by browning your ground beef in a skillet over medium-high heat. Break it up with a spatula and cook until it’s no longer pink. Drain any excess fat.

Step 2: Prep the Base

Peel and dice your Yukon Gold potatoes, chop the onion, and mince the garlic. Add them to the bottom of your slow cooker.

Step 3: Build the Layers

Top the potatoes with the browned beef. Then add in the diced tomatoes with green chiles, kidney beans, corn, and cream of mushroom soup. Season with salt and pepper.

Step 4: Stir and Cook

Gently stir everything together to combine. Cover and cook on low for 6-7 hours or high for 3-4 hours, until the potatoes are fork-tender.

Step 5: Finish and Serve

Just before serving, sprinkle with shredded cheddar cheese if using. Let it melt for a few minutes, then serve hot straight from the crock.
