Ingredients Notes

The beauty of this Slow Cooker Cowboy Casserole lies in its simple yet flavorful ingredients. Each component plays a key role in creating the perfect comfort food experience.

Ground Beef: Opt for lean ground beef (85/15) to reduce excess grease. Ground turkey or chicken can also be used for a lighter version.
Potatoes: Baby red or Yukon Gold potatoes work best, as they hold their shape during slow cooking. Cut them into bite-sized pieces for even cooking.
Cream of Mushroom Soup: This provides the creamy, savory base for the casserole. You can use cream of chicken soup as a substitute if preferred.
Corn: Canned or frozen sweet corn adds a pop of color and sweetness that balances the richness of the dish.
Diced Tomatoes with Green Chiles: These give the casserole a touch of tangy heat. If you prefer a milder flavor, use regular diced tomatoes.
Shredded Cheese: A mix of cheddar and Monterey Jack works beautifully here, but feel free to use your favorite melty cheese blend.

Special Equipment

A 6-quart slow cooker is ideal for this recipe. If you’re making a smaller portion, a 4-quart slow cooker will also work.

How to Make This Slow Cooker Cowboy Casserole

Creating this hearty casserole is as easy as layering and letting your slow cooker do the work. Let’s break it down step by step.

Prep the Ingredients
Begin by browning 1 pound of ground beef in a skillet over medium heat. Season with salt and pepper, then drain any excess grease. Meanwhile, wash and cut the potatoes into bite-sized chunks.
Layer the Ingredients
Spray the slow cooker with nonstick cooking spray for easy cleanup. Start by layering half of the potatoes at the bottom. Add half the ground beef, then sprinkle on half the corn, followed by half the can of diced tomatoes with green chiles. Repeat the layers with the remaining ingredients.
Add the Creamy Sauce
In a small bowl, mix the cream of mushroom soup with ¼ cup of milk. Pour this mixture evenly over the top of the layered ingredients, ensuring everything is coated.
Cook Low and Slow
Cover the slow cooker with the lid and set it to low heat for 6-7 hours or high heat for 3-4 hours. The potatoes should be tender when pierced with a fork, and the flavors will have melded beautifully.
Add the Cheese
During the last 20 minutes of cooking, sprinkle a generous amount of shredded cheese on top. Replace the lid and allow the cheese to melt before serving.

This casserole is best served warm, straight from the slow cooker, with a sprinkle of fresh parsley for garnish!
