In a large skillet, melt 2 tablespoons of butter over medium heat. Add sliced mushrooms and cook until tender and browned, about 8-10 minutes.

Gradually whisk in the milk, continue whisking until the mixture thickens, about 3-5 minutes.

Add salt and garlic powder, then stir in shredded Swiss and mozzarella cheeses until melted and smooth.

Combine cooked noodles with the beef and mushroom mixture. Pour cheese sauce over and mix thoroughly. Season with salt and pepper to taste. Serve hot.
