Ingredients Notes

The beauty of Slow Cooker Cowboy Casserole lies in its simple, wholesome ingredients. Each component plays a key role in creating that hearty, home-cooked flavor.

Ground Beef

For the best results, use lean ground beef (85/15 or 90/10). It provides just the right amount of flavor without making the dish too greasy. If you're using higher-fat beef, be sure to drain the excess grease after browning.

Potatoes

I recommend russet or Yukon Gold potatoes, as they hold their shape well during slow cooking. Slice them evenly so they cook through at the same rate. You can also use baby potatoes for a rustic touch.

Beans

Kidney beans add a hearty, protein-packed element, but feel free to swap them with black beans or pinto beans based on your preference. If using canned beans, be sure to drain and rinse them to remove excess sodium.

Tomatoes

A can of diced tomatoes with green chilies (like Rotel) gives this dish a mild kick. If you prefer a milder version, use plain diced tomatoes instead.

Cheese

Cheddar cheese melts beautifully into the casserole, adding a rich, creamy texture. Feel free to experiment with Monterey Jack or a Mexican cheese blend for extra flavor.

Special Equipment

A 6-quart slow cooker works best for this recipe. If you're making a smaller batch, a 4-quart cooker will do, but you may need to adjust the layering slightly.

How To Make Slow Cooker Cowboy Casserole

Making this Slow Cooker Cowboy Casserole is as easy as layering the ingredients and letting the slow cooker do all the work!

Step 1: Brown the Beef

Start by heating a large skillet over medium-high heat. Add the ground beef and cook until browned, breaking it up with a wooden spoon. Drain any excess grease, then season with garlic powder, onion powder, salt, and black pepper for extra flavor.

Step 2: Layer the Ingredients

In your slow cooker, start with a layer of sliced potatoes. Next, add the browned beef, followed by a layer of beans and corn. Pour in the diced tomatoes with green chilies and spread them evenly over the top.

Step 3: Add the Sauce

In a small bowl, mix cream of mushroom soup with beef broth until smooth. Pour this mixture over the layers in the slow cooker. This helps keep everything moist and creates that rich, creamy texture as it cooks.

Step 4: Let It Cook

Cover and cook on LOW for 6-7 hours or HIGH for 3-4 hours, until the potatoes are fork-tender.

Step 5: Add Cheese and Serve

About 30 minutes before serving, sprinkle shredded cheddar cheese over the top. Cover again and let it melt into the casserole. Once it’s melted and gooey, scoop out generous portions and enjoy!

The result? A warm, cheesy, and hearty casserole that’s packed with flavor and perfect for any occasion.

Storage Options

If you have leftovers (which is rare in my house!), this cowboy casserole stores beautifully for easy future meals.

Refrigerator: Store leftovers in an airtight container for up to 4 days.
Freezer: To freeze, let the casserole cool completely, then transfer portions to freezer-safe containers or bags. It stays fresh for up to 3 months.
Reheating: Warm leftovers in the microwave for 2-3 minutes, stirring halfway through. If reheating from frozen, thaw overnight in the fridge before microwaving or warming in a skillet.

Variations and Substitutions

One of the best things about Slow Cooker Cowboy Casserole is how easily you can customize it to suit your taste and dietary needs.

Make It Spicier

Love a little heat? Add chopped jalapeños, a dash of hot sauce, or extra chili powder for a spicy kick.

Swap the Meat

Not a fan of ground beef? Try using ground turkey, sausage, or even shredded rotisserie chicken for a different flavor twist.

Go Vegetarian

For a meatless version, swap the beef for lentils, mushrooms, or extra beans. A little smoked paprika can help mimic that rich, meaty depth.

Add More Veggies

Boost the nutrition by adding bell peppers, zucchini, or carrots. Just dice them small so they cook evenly.

Try a Different Cheese

Instead of cheddar, experiment with pepper jack, smoked gouda, or a Mexican blend for a unique flavor twist.

No matter how you make it, this Slow Cooker Cowboy Casserole is guaranteed to be a hit. Give it a try and let me know how you customize yours!
