Ingredients

Ground beef adds the hearty base of the casserole and gives it that cowboy-style satisfaction. Cream of mushroom soup provides a creamy, savory element that binds everything together perfectly. Shredded cheddar cheese delivers that melty, cheesy goodness you crave in a comfort meal. Frozen tater tots are the golden, crispy topping that makes every bite a treat. Sour cream adds a subtle tanginess that balances the richness of the other ingredients. Chopped onion boosts the flavor depth, adding aromatic warmth. Garlic powder, salt, and pepper round out the seasoning to bring the whole dish to life. And green onions on top add a pop of freshness and color.

How to Make Slow Cooker Cowboy Casserole

Step 1: Brown the Beef

In a large skillet over medium-high heat, cook the ground beef until browned and no longer pink. Drain any excess fat. This step adds flavor and ensures the meat has the perfect texture.

Step 2: Mix the Sauce Base

In a mixing bowl, combine the cream of mushroom soup, sour cream, chopped onion, garlic powder, salt, and pepper. Stir until smooth and well blended. This mixture will infuse the casserole with creamy, tangy flavor.

Step 3: Layer the Ingredients

In your slow cooker, layer half of the cooked ground beef, then half of the sauce mixture, followed by a layer of shredded cheddar and a layer of frozen tater tots. Repeat the layers one more time, ending with a generous topping of cheese.

Step 4: Cook Low and Slow

Cover and cook on low for 5 to 6 hours, or until the tater tots are golden and everything is heated through. The slow cooking allows all the flavors to meld beautifully.

Step 5: Garnish and Serve

Once done, sprinkle chopped green onions over the top just before serving for a burst of freshness and color. Serve hot and enjoy the comforting layers of flavor.

Recipe Variations and Possible Substitutions

This Slow Cooker Cowboy Casserole is wonderfully versatile. If you want a leaner option, ground turkey or chicken works well in place of beef. For a richer flavor, try using cream of chicken or even cream of cheddar soup. Love veggies? Add in corn, black beans, or bell peppers for extra texture and nutrition. Swap the cheddar for Monterey Jack or a spicy pepper jack if you like a little kick. And for those avoiding dairy, use a plant-based sour cream and cheese alternative.

Serving and Pairing Suggestions

This casserole is a full meal on its own, but it also pairs nicely with a crisp green salad or steamed vegetables like broccoli or green beans to lighten up the plate. Want to take it over the top? Serve it with a side of warm, crusty bread or cornbread to soak up every creamy bite. For drinks, a cold glass of iced tea or a light beer complements the hearty flavors perfectly.

Storage and Reheating Tips

Store any leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place a portion in the microwave and cover with a damp paper towel to keep the moisture in—heat in 30-second bursts until warmed through. For the oven, cover with foil and bake at 350°F for about 15 minutes. This casserole also freezes well. Just store it in a freezer-safe container, thaw overnight, and reheat using your preferred method.
