Preheat your oven to 375°F (190°C) to prepare for baking.
In a large mixing bowl, combine the ground beef, finely chopped onion, minced garlic, breadcrumbs, beaten egg, Worcestershire sauce, and a generous pinch of salt and black pepper. Mix thoroughly until all ingredients are evenly incorporated.
Form the meat mixture into four oval patties, each approximately 1 inch thick.
Heat a large skillet over medium heat and add a drizzle of oil. Once hot, add the patties and sear them for about 4 minutes on each side until they are nicely browned. They do not need to be fully cooked at this stage. Remove the patties from the skillet and set aside.
In a greased 9x13-inch baking dish, arrange half of the sliced potatoes in an even layer at the bottom. Season lightly with a sprinkle of salt and black pepper.
Carefully place the browned meat patties over the layer of potatoes, ensuring they are evenly spaced.
Arrange the rest of the sliced potatoes over the patties, again seasoning lightly with salt and black pepper.
Gently pour the beef broth over the entire dish, making sure to cover all the potatoes.
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes.
After 45 minutes, remove the foil, sprinkle the shredded cheddar cheese generously over the top, and return the dish to the oven uncovered. Bake for an additional 15 minutes until the cheese is melted and bubbly, and the potatoes are fork-tender.
Once finished baking, remove the dish from the oven and allow it to cool for a few minutes. Just before serving, garnish with freshly chopped parsley.
Notes
Serve directly from the baking dish for a rustic appeal.
