Ingredients Notes

The magic of the Slow Cooker Cowboy Casserole lies in its simple, wholesome ingredients. Here’s what you’ll need and why they matter.

Ground Beef: The hearty base of this casserole. Opt for lean ground beef to minimize grease, but feel free to substitute with ground turkey or chicken for a lighter option.
Potatoes: Russet potatoes work best for this recipe as they hold their shape during slow cooking. Dice them evenly to ensure even cooking.
Onions and Garlic: These aromatics provide a flavorful foundation for the dish, enhancing every bite with a savory depth.
Cream of Mushroom Soup: This classic ingredient brings a creamy, comforting texture to the casserole. If you're not a fan, cream of chicken works just as well.
Cheese: Shredded cheddar cheese adds a gooey, melty layer of goodness. You can use your favorite cheese blend for extra flavor.
Vegetables: Canned corn and green beans not only add color but also balance the dish with a touch of sweetness and crunch.
Seasonings: A mix of paprika, salt, and pepper rounds out the flavors, giving the dish a subtle kick.

You'll also need a large slow cooker to bring it all together. A 6-quart model works perfectly for this recipe.

How To Make This Slow Cooker Cowboy Casserole

Creating this delicious casserole is as easy as layering and letting your slow cooker do the work. Follow these simple steps for the ultimate comfort food.

Prepare Your Ingredients: Begin by browning 1 pound of ground beef in a skillet over medium heat. Season with salt, pepper, and paprika as it cooks, and drain any excess grease. While the beef cools, dice 4-5 medium russet potatoes into ½-inch cubes and finely chop 1 onion and 2 cloves of garlic.
Layer the Ingredients: Spray your slow cooker with non-stick cooking spray. Start with a layer of the diced potatoes, followed by half of the browned beef, half of the chopped onions, and a sprinkle of shredded cheddar cheese. Repeat the layers until all ingredients are used, ending with cheese on top.
Add the Creamy Base: In a separate bowl, mix 1 can of cream of mushroom soup with 1 cup of milk until smooth. Pour this mixture evenly over the layered ingredients in your slow cooker.
Cook Low and Slow: Cover the slow cooker with its lid and cook on low for 6-7 hours or on high for 3-4 hours. The potatoes should be fork-tender, and the flavors melded beautifully.
Finish and Serve: About 30 minutes before serving, sprinkle an additional layer of shredded cheddar cheese on top, allowing it to melt into the casserole. Serve hot, garnished with chopped parsley for a fresh touch.

This dish takes about 10 minutes to prep, and the slow cooker does the rest, giving you a meal that’s both effortless and unforgettable.

Storage Options

If you’re lucky enough to have leftovers, this casserole stores beautifully. Here’s how to keep it fresh:

Refrigerator: Place leftovers in an airtight container and store them in the fridge for up to 3 days.
Freezer: For longer storage, portion the casserole into freezer-safe containers or bags. Freeze for up to 3 months.
Reheating: Warm individual servings in the microwave or reheat the entire dish in a 350°F oven until heated through.

This casserole tastes just as good, if not better, the next day as the flavors continue to meld together.

Variations and Substitutions

One of the best things about the Slow Cooker Cowboy Casserole is its flexibility. Here are some ideas to make it your own:

Swap the Protein: Try ground turkey, chicken, or even sausage for a different flavor profile.
Add Veggies: Incorporate bell peppers, diced tomatoes, or even jalapeños for a spicy kick.
Use Sweet Potatoes: Replace the russet potatoes with sweet potatoes for a slightly sweet twist.
Make It Gluten-Free: Opt for a gluten-free cream of mushroom soup and double-check your seasonings to ensure a celiac-safe dish.
Cheese Options: Experiment with pepper jack, Monterey Jack, or a smoked cheese for added flair.

Don’t be afraid to experiment with this dish. The slow cooker is forgiving, and the results are always satisfying.
