Creating the Slow Cooker Steak and Cheddar Potato Casserole is simple and rewarding. Follow these steps to ensure a delicious result:

1. Prepare the Steak: Season the beef steak pieces with salt, black pepper, garlic powder, and onion powder. Toss to coat evenly.
2. Layer Ingredients: In the slow cooker, layer the diced potatoes and onions at the bottom. Add the seasoned steak pieces on top.
3. Add Corn: Sprinkle the corn over the steak layer for an extra touch of flavor and texture.
4. Combine Liquids: In a bowl, mix together the beef broth, heavy cream, and Worcestershire sauce. Pour this mix over the casserole layers in the slow cooker.
5. Cook the Casserole: Cover the slow cooker with its lid and set it on low for 6–8 hours or high for 4–5 hours. Cooking on low will yield the most tender results.
6. Melt the Cheese: About 30 minutes before serving, add 1½ cups of shredded cheddar cheese on top of the casserole. Cover and let the cheese melt.
7. Serve: Once cooked, stir the casserole gently to combine ingredients. Adjust seasoning to taste if needed.
8. Garnish: Top with additional shredded cheese and fresh parsley for a beautiful presentation if desired.

These straightforward steps will guide you in creating this incredible dish with minimal hassle.
