Cook the pasta in boiling water until 1–2 minutes short of the package's full cooking time, then drain. Keep a little pasta water to loosen the filling if it looks dry.

Brown the ground meat in a skillet, breaking it into small pieces. Drain excess fat before mixing it with the sauce and other filling ingredients.

Preheat your oven to 375°F (190°C).

Cook the egg noodles according to package instructions until al dente.

In a large skillet, brown the ground beef with the mushrooms over medium heat.

Once the beef is cooked through, add the beef broth, sour cream, and cream cheese to the skillet, stirring until everything is well combined and creamy.

Mix the cooked egg noodles into the beef mixture until evenly coated.

Transfer the mixture to a baking dish and sprinkle with Parmesan cheese on top.

Bake in the preheated oven for about 20-25 minutes, or until heated through and bubbly.

Let it cool for a few minutes before serving.

Continue baking as necessary until the center is hot and the edges are bubbling. If the topping browns too quickly, cover loosely with foil.

Rest for 5 minutes before serving.
