Season and Combine: Season the cheese sauce with salt and pepper to taste. Stir in the cooked macaroni until fully coated.
Transfer and Bake: Transfer the mixture to a greased baking dish. Bake in a preheated oven at 375°F (190°C) for 20-25 minutes, until bubbly and golden brown.
Remove and Rest: Let rest for 10-15 minutes before serving for the best creamy consistency.
