Make-Ahead Macaroni and Cheese

Serves 8 to 10

  1. Pulse the bread, Parmesan, garlic, and 2 tablespoons of the butter in a food processor until coarsely ground.
  2. Do ahead: Divide the crumb mixture between 2 zipper-lock bags and freeze for up to 2 months.
  3. Bring 4 quarts of water to a boil in a Dutch oven, or large pot, over high heat.
  4. Add 1 tablespoon salt and the pasta and cook, stirring often, until barely softened, about 3 minutes.
  5. Drain the pasta, then spread it out on a rimmed baking sheet to cool.
  6. Heat the remaining 6 tablespoons butter, the flour, mustard, and cayenne in the now-empty pot over medium-high heat, stirring constantly, until golden and fragrant, 1 to 2 minutes.
  7. Slowly whisk in the broth and cream and bring to a boil.
  8. Reduce the heat to medium and simmer until slightly thickened, about 15 minutes.
  9. Off the heat, whisk in the colby, cheddar, 1 teaspoon salt, and pepper until smooth.
  10. Stir the cooled pasta into the sauce, breaking up clumps, until well combined. Divide the pasta mixture between two 8-inch square baking dishes. Cool to room temperature, about 2 hours.
  11. Do ahead: Cover the dishes tightly with plastic wrap and foil, and freeze up to 2 months.
  12. To Serve

  13. Adjust an oven rack to the middle position and heat the oven to 375°F. Remove the foil from the casserol and reserve. Microwave the casserole until the mixture is thawed and beginning to bubble around the edges, 7 to 12 minutes, stirring and replacing the plastic halfway through the cooking time. (If preparing both dishes, microwave them 1 at a time.) Discard the plastic and cover the pan with the reserved foil.
  14. Bake for 20 minutes.
  15. Remove the foil and sprinkle with 1 bag of the frozen bread crumbs. (If preparing both dishes, sprinkle the second bag of crumbs over the second dish.)
  16. Continue to bake until the crumbs are golden brown and crisp, about 20 minutes longer.
  17. Let cool for 10 minutes and serve.
