Let’s dive into the process of crafting this comforting dish. Follow these straightforward steps, and you’ll be on your way to a delightful meal:

1. Begin by seasoning the steak pieces with salt, pepper, garlic powder, and onion powder.
2. In a large skillet, sear the steak on all sides until browned, about 5 minutes. This helps lock in the flavor.
3. Layer half of the potatoes at the bottom of your slow cooker, followed by half of the onion and half of the cheese.
4. Add the seared steak on top, then add the remaining potatoes, onion, and cheese.
5. In a small bowl, mix together the beef broth and Worcestershire sauce. Pour this mixture over the ingredients in the slow cooker.
6. Cover and cook on low for 6-8 hours or until the potatoes are tender and the flavors have melded together.
7. About 30 minutes before serving, stir in the cornstarch mixture to thicken the sauce.
8. Once the casserole is ready, give it a final taste and adjust seasonings if necessary.

Cooking this dish always brings back memories of my grandmother’s kitchen, where I’d watch her create magic with simple ingredients. It’s a reminder that great food doesn’t have to be complicated.
