Ingredients

  • Kosher salt
  • 1 pound elbow macaroni
  • 2 1/2 cups half and half
  • 1/8 to 1/4 teaspoon cayenne pepper
  • 1 pound cream cheese, room temperature
  • 8 ounces sharp Cheddar, shredded (about 3 cups)
  • 3 ounces gruyere cheese, shredded (about 1 cup)
  • 1 cup panko bread crumbs
  • 4 tablespoons unsalted butter, melted

Method

  • Set an oven rack 6 inches from the heat source and preheat the oven to 425 degrees F.
  • Bring a large pot of salted water to a boil.
  • Add the macaroni and cook until it is al dente, about 6 minutes.
  • Strain, reserving 1 3/4 cups of the pasta water.
  • Set aside.
  • Heat the half-and-half and cayenne in a large saucepan over medium heat until it just comes to a simmer.
  • Continue simmering until the half-and-half is reduced to 1 1/2 cups, about 15 minutes.
  • Add the cream cheese and stir until melted.
  • Whisk in the Cheddar and Gruyere until all the cheese is melted and the sauce is smooth.
  • Add the macaroni and the reserved pasta water to the saucepan and stir to combine.
  • (It will look very loose, but the pasta will suck up a lot of the sauce as it bakes.)
  • Season to taste with salt if needed.
  • Pour into a 13-by-9-inch baking dish.
  • Toss the bread crumbs with the butter and a sprinkle of salt in a small bowl and sprinkle evenly over the top of the macaroni and cheese.
  • Bake until the cheese is bubbly and the bread crumbs are lightly browned and crispy, about 10 minutes.
