How to Make Hearty Slow Cooker Cowboy Casserole

Brown the Beef

Heat a skillet over medium heat and brown the ground beef for 6–8 minutes. Add the diced onion and cook until softened. Drain excess fat, then stir in the garlic and cook for about 30 seconds until fragrant.

Prepare the Slow Cooker

Lightly grease your slow cooker to prevent sticking and make cleanup easier.

Layer the Casserole

Add half of the diced potatoes to the bottom of the slow cooker. Top with half of the beef mixture and half of the corn. Repeat the layers with the remaining potatoes, beef, and corn.

Add the Sauce

In a bowl, whisk together the cream of mushroom soup, milk, paprika, salt, black pepper, and dried parsley. Pour the mixture evenly over the layered casserole, making sure it reaches all areas.

Slow Cook

Cover and cook on low for 6–7 hours or on high for 3–4 hours, until the potatoes are fork-tender and fully cooked.

Add the Cheese

During the last 20 minutes of cooking, sprinkle the shredded cheddar cheese evenly over the top. Cover again and allow the cheese to melt.

Serve

Serve hot straight from the slow cooker and enjoy a comforting, hearty meal.

Tips for Success

Dice the potatoes evenly so they cook at the same rate. Browning the beef first adds extra flavor and prevents excess grease in the casserole. For best texture, use freshly shredded cheese, which melts more smoothly than pre-shredded varieties.
