Ingredients for the Slow Cooker Cowboy Casserole

This slow cooker dinner is full of layered textures and cozy flavors. The ingredients are easy to find and flexible to adapt based on what’s in your pantry or fridge.

Ground beef brings hearty flavor and a satisfying bite to every spoonful.

Yellow onion adds sweetness and depth as it softens during the slow cooking process.

Minced garlic enhances the aroma and adds warmth to the dish.

Russet potatoes give the casserole its comforting, chunky base—peel and dice them into bite-size pieces.

Diced tomatoes with green chilies provide tang, moisture, and a little kick.

Kidney beans offer creamy texture and protein that complements the beef.

Cream of mushroom soup ties everything together with a rich, velvety consistency.

Cheddar cheese melts beautifully and adds that gooey, savory topping everyone loves.

Salt and black pepper are essential for seasoning all the layers just right.

How To Make the Slow Cooker Cowboy Casserole

Step 1: Brown the Beef

Start by browning the ground beef in a skillet over medium heat. Add the chopped onions and minced garlic and cook until the beef is fully browned and the onions are soft. Drain any excess grease.

Step 2: Layer the Ingredients

In your slow cooker, add a layer of diced potatoes at the bottom. Spoon the beef mixture over the top. Add the diced tomatoes with green chilies, drained kidney beans, and cream of mushroom soup. Stir gently to combine.

Step 3: Slow Cook to Perfection

Cover the slow cooker and cook on low for 6-7 hours or on high for 3-4 hours, until the potatoes are tender.

Step 4: Add the Cheese

About 15-20 minutes before serving, sprinkle the top with cheddar cheese and cover again until melted and bubbly.

Step 5: Serve and Enjoy

Give everything a gentle stir if desired, then scoop into bowls and serve warm.
