Ingredients Notes

The magic of this Slow Cooker Cowboy Casserole lies in its simple, pantry-friendly ingredients. Each one contributes to the dish’s rich and hearty flavor.

Ground beef is the star protein in this dish. I recommend using 85/15 ground beef for the perfect balance of flavor and tenderness. If using leaner beef, you may want to add a splash of oil to keep things juicy.

Potatoes provide the hearty, starchy base for this casserole. Russet potatoes work well because they hold their shape, but Yukon Golds offer a buttery texture if you prefer.

Cream of mushroom soup creates a creamy, flavorful sauce that binds everything together. If you're not a fan of canned soups, you can substitute with homemade cream sauce.

Diced tomatoes and kidney beans add a Tex-Mex twist to the dish. The tomatoes provide a slight acidity that balances out the richness, while the beans give it a satisfying, chili-like heartiness.

Cheese is the finishing touch! A generous sprinkle of shredded cheddar melts beautifully on top, adding a creamy, gooey element that ties everything together.

You’ll also need a slow cooker to bring it all together effortlessly. A 6-quart slow cooker is the perfect size for this recipe.

How To Make This Slow Cooker Cowboy Casserole

Creating this mouthwatering Slow Cooker Cowboy Casserole is as easy as layering ingredients and letting your slow cooker do the work.

Start by browning the ground beef in a large skillet over medium heat. Cook until no longer pink, breaking it up with a spoon. Drain any excess grease to keep the casserole from becoming too oily.

Next, prep your potatoes by peeling and slicing them into thin rounds. This ensures they cook evenly and become perfectly tender in the slow cooker.

Now, it’s time to assemble the casserole. Lightly grease your slow cooker, then layer half of the sliced potatoes at the bottom. Add half of the cooked ground beef, followed by a sprinkle of salt, pepper, and garlic powder.

Repeat the layers, adding the remaining potatoes and beef. Pour the diced tomatoes and drained kidney beans over the top, ensuring they’re evenly distributed.

In a small bowl, mix the cream of mushroom soup with a little bit of water or broth to thin it out slightly. Pour this mixture over the top, making sure it seeps into all the layers.

Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the potatoes are fork-tender. About 30 minutes before serving, sprinkle the shredded cheese on top and let it melt into the casserole.

Once done, give everything a gentle stir to mix the flavors, then scoop out hearty portions and enjoy!

Storage Options

This Slow Cooker Cowboy Casserole is perfect for meal prep and leftovers. Here’s how to store it for maximum freshness.

For refrigeration, allow the casserole to cool completely before transferring it to an airtight container. It will stay fresh in the fridge for up to 4 days.

To freeze, portion the casserole into freezer-safe containers or resealable bags. It can be frozen for up to 3 months. When ready to eat, thaw it overnight in the fridge before reheating.

For reheating, microwave individual portions for 2-3 minutes, stirring halfway through. You can also warm it in a covered dish in the oven at 350°F for 15-20 minutes until heated through.

Variations and Substitutions

One of the best things about this Slow Cooker Cowboy Casserole is how versatile it is. Here are some fun ways to change it up!

Want to add a little spice? Toss in some diced jalapeños or a dash of cayenne pepper for a kick of heat.

For a healthier twist, use ground turkey or chicken instead of beef. You can also swap the cream of mushroom soup for a lightened-up homemade version.

If you love extra veggies, try adding bell peppers, corn, or even spinach. They’ll blend right in and add a fresh burst of flavor.

Cheese lovers can mix it up by using different cheeses like pepper jack, Monterey Jack, or even smoked gouda for a new depth of flavor.

No potatoes on hand? Swap them out for sweet potatoes or even cooked pasta for a fun twist.
