How to make the best Mac & Cheese?


  • 1 lb. dried elbow pasta
  • ½ cup unsalted butter
  • ½ cup all-purpose flour
  • 1 ½ cups whole milk
  • 2 ½ cups half and half
  • 4 cups grated medium sharp cheddar cheese divided (measured after grating)
  • 2 cups grated Gruyere cheese divided (measured after grating)
  • ½ Tbsp. salt
  • ½ tsp. black pepper
  • ¼ tsp. paprika


  1. Preheat the oven at 325℉ for 15-20 minutes. Grease a 9-by-13 baking tray with butter or vegetable oil.
  1. In a large pot, add plenty of water. Add salt. When the water comes to a rolling boil, add dry pasta. Cook the pasta until al dente. Drain the pasta water. Do not rinse the pasta. Toss it with some olive oil to keep it from sticking.
  1. Grate the cheese and divide it into 3 portions. Separate 3 cups for the sauce, 1 1/2 cups for the inner layer, and 1 1/2 cups for the topping.
  1. In a large saucepan, melt butter. Add the flour and whisk it well until combined in butter or until the mixture is homogenous and sandy. Cook the butter with flour for about 1 minute.
  1. Then pour some milk while whisking the mixture continuously. When the mixture is creamy, add the rest of the milk while whisking.
  1. Keep whisking and heating the mixture on medium heat until it becomes thick and creamy like a condensed soup.
  1. Now remove the mixture from the heat. Finish off with spices and grated cheese. Whisk the cheese in while the mixture is still hot so that it melts and the sauce is smooth.
  1. In a separate bowl, mix the sauce with pasta. Pour half of this pasta mixture into the greased baking tray. Sprinkle with 1 ½ cup of grated cheese. Top with the rest of the pasta mixture.
  1. Top off the pasta mixture with the remaining 1 ½ cup of grated cheese. Slide the tray in the oven and bake for 15-20 minutes or until the cheese has turned golden and is bubbling.
