Step-by-Step Instructions
Step 1 – Brown the Meat
In a skillet, cook ground beef with onion and garlic until browned. Drain excess fat. (💡 Pro Tip: Browning before slow cooking prevents greasy texture and deepens flavor.)
Step 2 – Layer the Ingredients
Spray slow cooker with non-stick spray.
- Spread half the sliced potatoes on the bottom.
- Add half the beef mixture.
- Layer half of the beans, corn, and tomatoes.
- Repeat layers, ending with potatoes on top.
Step 3 – Mix the Sauce
In a bowl, whisk cream of mushroom soup with milk, Worcestershire sauce, and seasonings. Pour evenly over the layered casserole.
Step 4 – Slow Cook
- Low heat: 6–7 hours
- High heat: 3–4 hours
(💡 Pro Tip: Avoid lifting the lid too often—every peek adds 20 minutes to cooking time.)
Step 5 – Add Cheese & Serve
Sprinkle shredded cheese on top 10 minutes before serving. Let melt, then dish out warm.
