Slow Cooker Cowboy Casserole

(Serves 6–8)

  • 1½ lbs (680g) ground beef (80/20 for best flavor)
  • 1 small yellow onion, diced
  • 1 (10 oz) bag frozen shredded hash browns, thawed
  • 1 (15 oz) can corn kernels, drained
  • 1 (15 oz) can black beans or pinto beans, drained & rinsed
  • 1 (10 oz) can diced tomatoes with green chiles (Rotel)
  • 1 (10 oz) can cream of mushroom or cream of celery soup
  • 1 cup shredded cheddar cheese (plus extra for topping)
  • 1 packet (1 oz) ranch seasoning mix (or 2 tbsp homemade)
  • ½ tsp garlic powder
  • Salt & black pepper to taste
  • Optional: Cooked bacon bits, diced green chiles, or jalapeños

💡 Pro Tips:

  • Brown beef with onion—drain excess fat for best texture.
  • Thaw hash browns—prevents icy chunks and uneven cooking.
  • Use low-sodium soup & beans—gives you control over salt.

Step-by-Step Instructions (Hearty, Hands-Off, Foolproof)

1. Brown the Beef

  • In a skillet, cook ground beef and onion over medium heat until browned. Drain excess fat.
  • Optional: Add ½ tsp cumin or smoked paprika for smoky depth.

2. Layer in the Slow Cooker

  • In a 6-quart slow cooker, combine:
    → Browned beef mixture
    → Hash browns
    → Corn
    → Beans
    → Rotel
    → Cream of mushroom soup
    → Ranch seasoning
    → Garlic powder, salt, and pepper
  • Gently stir until evenly mixed (don’t overmix—keep hash browns intact).

3. Cook Low & Slow

  • Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until hash browns are tender and flavors meld.

4. Add Cheese & Serve

  • Stir in 1 cup cheddar cheese until melted.
  • Top with extra cheese, green onions, or sour cream.
  • Let rest 10 minutes before serving (helps it set slightly).

  • 🥗 Balance it: Simple green salad with ranch dressing
  • 🌶️ Spicy kick: Hot sauce or pickled jalapeños on the side
