How To Make the Slow Cooker Cowboy Casserole

Step 1: Brown the Beef and Aromatics

In a large skillet over medium-high heat, cook the ground beef until it’s browned and cooked through. Add diced onions and minced garlic; sauté until the onions are translucent. Drain any excess fat.

Step 2: Layer the Ingredients

Lightly grease your slow cooker insert. Add the diced potatoes, browned beef with onions and garlic, corn, kidney beans, diced tomatoes with juices, tomato sauce, beef broth, chili powder, salt, and pepper. Gently stir to combine everything evenly.

Step 3: Slow Cook to Perfection

Cover and cook on low for 6–7 hours, or on high for 3–4 hours, until the potatoes are tender and flavors meld together.

Step 4: Add the Cheesy Topping

About 10 minutes before serving, sprinkle the shredded cheddar cheese evenly over the casserole. Cover and let it melt. Just before serving, garnish with chopped fresh parsley if desired.
