Cook pasta: Bring a large pot of water to a boil, and add salt generously. Cook macaroni according to the packet's instructions. Reserve about 1 cup of pasta water. Drain well.1 lb elbow macaroni/ 450 g
Melt cheese: Shortly before the pasta is cooked, heat a large saucepan. Add grated cheese, cream cheese, mustard, some salt, and pepper. Melt cheese on low heat, constantly stirring, for about 2 minutes. Don't overheat the mixture.8 oz Cheddar cheese/ 220 g + 4 oz mozzarella/ 115 g + 8 oz package cream cheese/ 220 g + 1 teaspoon Dijon mustard + fine sea salt + ground black pepper
Combine: Add drained pasta and about ¼ - ½ of the reserved pasta water (as needed for a creamy consistency) and stir to combine. Adjust the taste with more salt and pepper if necessary. Serve immediately.
Notes
Pasta choice: Any other short pasta shape will be fine.
Don't forget to reserve some pasta water before draining the noodles.
Cheese: You can use other cheese sorts as well - for example, Gouda, Fontina, Swiss, Provolone, and so on.
