Rohlík's Mac and Cheese

Cook pasta in salted water until al dente. Drain and set aside.

Prepare the cheese sauce: In a saucepan over medium heat, melt the butter, add the flour, and whisk for one minute until the mixture thickens. Slowly pour in the milk and cream, whisking constantly.

Add Dijon mustard, smoked paprika, salt, and pepper. Then gradually stir in the cheddar, Gruyère, and Parmesan until the cheese is completely melted and the sauce is smooth.
