Preheat the oven to 375°F (190°C) and grease a 9 x 13-inch baking dish. Brown the ground beef and onion, then drain excess grease before adding the seasonings. Stir in the cream of mushroom soup, sour cream, and beef broth, then melt 1 cup of cheddar into the mixture. Top with the remaining cheese and bake uncovered for 20–25 minutes until hot and bubbly. For a deeper golden topping, broil for 1–2 minutes, watching closely. Rest for 5 minutes before serving and garnish with optional fresh parsley. Refrigerate leftovers in an airtight container for up to 4 days. Nutrition values are estimates, assuming 6 servings.
