This classic macaroni and cheese is extra creamy and rich with a great cheddar flavor.
Cook the macaroni noodles in a large pot of salted water according to package directions, draining them a minute before the "al dente" cooking time.
Heat the milk in the microwave or on the stove top until very hot but not boiling.
In a heavy bottomed sauce pot, melt the butter over medium heat. Whisk in the flour and continue to cook, whisking constantly, until the mixture turns a light brown color. Remove from heat. Slowly start pouring in the milk, whisking constantly. The mixture will look very thick at first and will thin out as you whisk in the remainder of the milk. Return the pot to the heat and cook the mixture, whisking continuously, another 3-5 minutes or until thickened. The sauce should coat the back of the spoon. If you put a little bit on a spoon and run your finger through it, the line from your finger should remain. Stir in the salt and ground mustard. Remove 1 cup of the sauce and store it in airtight container in the fridge to be used for creamy soups or sausage gravy.
Return the remaining sauce to the stove. Over low heat, add the cheeses, stirring to melt. If you're unable to melt in all the cheese, add a bit more milk, a Tablespoon at a time, until the cheese is melted completely. Add the cooked pasta to the cheese and stir until well coated and heated through. Taste and season with salt and pepper if needed or simply serve hot with a sprinkle of parsley.
I recommend Barilla or Ronzoni large elbows for the pasta. For the cheese, look for a good quality aged cheddar, preferably aged over 9 months. I recommend Tillamook.
This recipe makes 3 cups of bechamel sauce, but you'll only need two to make the mac and cheese. Save the third cup to make a creamy soup or delicious sausage gravy.
