How to Make Slow Cooker Cowboy Casserole

Step 1: Brown the beef
In a skillet over medium heat, cook the ground beef with diced onions and garlic until fully browned. Drain any excess grease.

Step 2: Layer the ingredients
Spray the inside of your slow cooker with non-stick spray. Add half the sliced potatoes to the bottom, followed by half the ground beef mixture, a sprinkle of ranch seasoning, and half of the drained beans and corn. Repeat the layers.

Step 3: Add tomatoes and cook
Pour the diced tomatoes (with juice) evenly over the top. Cover and cook on low for 6–7 hours or on high for 3–4 hours, until potatoes are fork-tender.

Step 4: Add cheese
About 15 minutes before serving, sprinkle shredded cheddar cheese over the top and let it melt. Garnish with chopped parsley or green onions if desired.

Step 5: Serve hot
Scoop into bowls and enjoy with crusty bread or a simple side salad.
