Historically, “cowboy casserole” likely got its name from being the kind of meal you’d imagine being cooked over an open fire out on the range—filling, simple ingredients that could feed a crowd.

This particular recipe has become a favorite in our household during the colder months. It’s the kind of dish that gets better the longer it cooks, making it perfect for busy days when you want to throw everything in the slow cooker and come home to the irresistible smell of something warm and ready to eat.

HOW TO MAKE SLOW COOKER COWBOY CASSEROLE:

STEP-BY-STEP INSTRUCTIONS:

Start by browning your ground beef in a skillet over medium heat. I always like to toss in the onions and garlic right from the start—the smell is heavenly and adds so much flavor. Cook until the beef is no longer pink and the onions are soft and fragrant.

Drain any excess fat, then transfer the beef mixture into the slow cooker. Now comes the fun part—layering everything in!

Add your sliced potatoes next. You can use a mandoline to make this quicker, but even hand-slicing works just fine. The thin slices cook up perfectly tender.

Toss in the kidney beans and corn, followed by the cream of mushroom soup, sour cream, and spices. Stir gently to combine everything into a creamy, savory mix.

Top it all off with shredded cheese, put the lid on, and let your slow cooker work its magic. Cook on low for 7–8 hours or high for 4–5 hours—just until those potatoes are fork-tender and everything is bubbling with cheesy goodness.

About 30 minutes before serving, sprinkle a little extra cheese on top and cover again so it gets all melty and gooey. Trust me—this step is worth it.

When it’s done, grab a big spoon, serve it into bowls, and maybe add a sprinkle of parsley or a dollop of sour cream on top for a little something extra.

HELPFUL TIPS:

Potato Shortcut: Don’t have time to slice? You can use frozen diced potatoes or hash browns in a pinch.
Make It a One-Pot Meal: Add chopped bell peppers or carrots for an extra veggie boost.
Spice It Up: Add diced green chilies or a dash of hot sauce if your crew likes a little heat.
Storage Tip: This dish reheats beautifully and makes even better leftovers the next day.
