How to Make Slow Cooker Cowboy Casserole

Step 1: Brown the Beef

Start by heating up a skillet over medium heat. Add the ground beef, chopped onion, and minced garlic. Sauté everything until the beef is browned and the onions have softened, stirring and breaking the meat up as you go. When the mixture is cooked, drain off any excess fat. This step gives layers of savory flavor as your base and helps keep the final casserole perfectly textured, not greasy.

Step 2: Mix the Base

Transfer your cooked beef mixture to the slow cooker bowl. Now, stir in the cream of mushroom soup, milk, kidney beans, diced tomatoes with green chilies, corn, chili powder, salt, and pepper. Give everything a thorough mix so everything is evenly distributed and coated—you want every spoonful of Slow Cooker Cowboy Casserole to burst with flavor.

Step 3: Layer the Potatoes

Now it’s time for the potatoes! Add them into the slow cooker and gently stir to make sure every slice is surrounded by that creamy, beefy mixture. The potatoes will soak up all the delicious juices as they cook, becoming melt-in-your-mouth tender and flavorful.

Step 4: Let the Slow Cooker Work Its Magic

Pop the lid on and set your slow cooker to low for 6–7 hours, or high for 3–4 hours, depending on your schedule. There’s something magical about coming home to a ready-made dinner that’s been slowly melding all day. The aroma alone is enough to bring everyone to the kitchen!

Step 5: Cheese Finale

With about 20 minutes of cooking time left, sprinkle your shredded cheese over the top. Cover again and let the cheese melt into a bubbly, golden topping. Once the cheese is irresistibly gooey, you’re ready to ladle out beautiful servings of Slow Cooker Cowboy Casserole.

Garnishes

Add a dollop of sour cream for a creamy, cooling contrast if you like!

Side Dishes

This casserole is a meal on its own, but it’s even better with the right sides. Try serving it with a crisp green salad for freshness, crusty bread for soaking up the extra sauce, or even a bowl of tangy coleslaw for crunch. Cornbread also makes a truly classic cowboy companion.

Make Ahead and Storage

Storing Leftovers

Slow Cooker Cowboy Casserole makes fantastic leftovers. Once cool, transfer any extras into airtight containers and store in the refrigerator for up to four days. The flavors actually deepen overnight, so you might find yourself looking forward to lunch the next day even more!

Freezing

This casserole is freezer-friendly, making it a lifesaver for future busy nights. Portion the cooled casserole into zip-top freezer bags or freezer-safe containers, pressing out the extra air. It’ll keep well for up to three months. Thaw overnight in the fridge before reheating for best results.

Reheating

To reheat, simply scoop servings into a microwave-safe dish and warm in the microwave, stirring occasionally, until piping hot. For larger quantities, reheat in an oven-safe dish covered with foil at 350°F until heated through. A quick sprinkle of extra cheese before reheating never hurts!

FAQs

Can I use a different type of meat?

Absolutely! Ground turkey, chicken, or even plant-based ground alternatives all work beautifully in Slow Cooker Cowboy Casserole. Just make sure to cook and drain the meat before adding it to the slow cooker.

Do I have to peel the potatoes?

Nope! If you’re using thin-skinned potatoes like Yukon golds or red potatoes, you can leave the skins on for added texture and nutrients. Just make sure to wash them well and slice evenly.

Is Slow Cooker Cowboy Casserole spicy?

This casserole has a mild kick from the diced tomatoes with green chilies and chili powder, but it’s generally kid-friendly. If you like things extra spicy, add chopped jalapeños or another dash of chili powder.

Can I make this dairy-free?

Yes! Use your favorite dairy-free cream of mushroom soup, plant-based cheese, and a dairy-free milk like almond or oat. The end result will still be rich and comforting.

Will it work in an Instant Pot?

While this recipe is designed for a slow cooker, you can use your Instant Pot’s slow cook function. For pressure cooking, you’d need to adjust the liquid and cook time, as potatoes may become too soft—so it’s best to stick to slow cook for the classic result.
