How to Make Cowboy Potato Casserole Recipe
Step 1: Brown the Beef and Vegetables
Start by heating your skillet over medium heat and adding the ground beef along with the chopped onion, garlic, and diced red bell pepper. Cook everything together until the beef is nicely browned and the vegetables have softened, bringing out their natural sweetness. Don’t forget to drain off any excess fat — this keeps your casserole rich but not greasy.
Step 2: Mix the Creamy Sauce
In a small bowl, combine the condensed cream of mushroom soup with milk, salt, black pepper, and paprika. This simple yet flavorful sauce is what gives your Cowboy Potato Casserole Recipe its velvety texture and rich, comforting personality.
Step 3: Assemble the Layers
Grab your slow cooker and start layering. Begin with half of the diced potatoes placed evenly on the bottom. Next, spoon half of the cooked beef and vegetable mixture over the potatoes, followed by half of the creamy soup sauce. Repeat this layering process with your remaining potatoes, meat mixture, and sauce — this builds those delicious pockets of flavor throughout the casserole.
Step 4: Slow Cook Until Tender
Cover the slow cooker and let it work its magic on low heat for 5 to 6 hours. This long, gentle cooking softens the potatoes to tender perfection and allows all the flavors to meld into one irresistible dish.
Step 5: Add the Cheesy Finish
When the potatoes are tender and the casserole looks ready, sprinkle the shredded cheddar cheese evenly over the top. Cover again and let it cook for another 20 minutes or until the cheese is completely melted and bubbling, creating a golden, gooey crown for your Cowboy Potato Casserole Recipe.
Step 6: Garnish and Serve
Just before serving, sprinkle freshly chopped parsley over the top. This fresh herb not only gives a lovely pop of color but also adds a light, bright contrast to the rich casserole underneath.
How to Serve Cowboy Potato Casserole Recipe

Garnishes
Aside from the fresh parsley, you can add a dollop of sour cream or a handful of chopped green onions for an extra layer of flavor and texture. These toppings bring a refreshing balance that cuts through the richness and makes every bite interesting.
Side Dishes
This casserole is a meal all on its own, but if you want to round it out, serving it alongside a crisp green salad or steamed vegetables adds a refreshing crunch and brightness that perfectly complements the warmth and earthiness of the dish.
Creative Ways to Present
Try serving individual portions in cute ramekins or even scoop out perfect mounds onto rustic plates with a sprinkle of extra cheese and herbs on top. This makes the Cowboy Potato Casserole Recipe adaptable and impressive for both casual family dinners and more festive occasions.
Make Ahead and Storage
Storing Leftovers
Once cooled, store any leftovers in an airtight container in the refrigerator. They will keep well for up to 3 days, allowing you to enjoy this cozy meal again without any hassle.
Freezing
If you want to save some for later, this Cowboy Potato Casserole Recipe freezes beautifully. Portion it into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) until heated through to preserve the casserole’s texture, or microwave individual servings for a quicker option. Adding a little splash of milk before reheating helps keep it creamy and moist.
FAQs
Can I use frozen potatoes for this casserole?
Absolutely! Frozen diced potatoes can be a convenient shortcut, but make sure to adjust cooking time slightly since they might cook faster than fresh potatoes.
What can I substitute for cream of mushroom soup?
If you want a homemade touch, try making a simple creamy sauce with butter, flour, milk, and mushrooms sautéed in it, or use another cream soup like cream of chicken for a different flavor profile.
Is this recipe suitable for a slow cooker only?
While it’s designed for the slow cooker’s gentle heat, you can bake it in the oven covered at 350°F for about 1.5 to 2 hours until the potatoes are tender, adding the cheese in the last 15 minutes.
How spicy is this casserole?
This recipe is mild with just a hint of paprika warmth, making it family-friendly. You can add a little cayenne pepper if you want a spicier kick.
Can I add other vegetables to this casserole?
Definitely! Feel free to toss in corn, green beans, or mushrooms to make it even more hearty and colorful — just mix them in with the beef and onions during cooking.
