  • Bring a large pot of salted water to a boil.

  • Add the warm milk and whisk gently over medium heat until the mixture has bubbled and thickened enough to coat the back of a spoon, about 10 minutes.
  • Stir in the salt, pepper, mustard, and most of the grated cheese, reserving 1/2 cup.
  • Add the pasta and toss to combine.
  • Distribute the mixture evenly in the prepared skillet or baking dish, and sprinkle the remaining cheese over the top.
  • Bake for 2025 minutes, until bubbling and browned.
