Homemade Mac and Cheese

Instructions

1. 01

   Arrange a rack in the middle of the oven and heat the oven to 350°F. Coat a 9x13-inch baking dish with butter.

2. 02

   Bring a large pot of heavily salted water to a boil. Add 1 pound dried elbow macaroni and cook for 2 minutes less than package directions for al dente. Meanwhile, grate 1 1/2 pounds medium cheddar cheese on the large holes of a box grater (about 6 cups). Reserve 1 cup of the cheese for sprinkling.

3. 03

   Drain the macaroni. Melt 6 tablespoons unsalted butter in the now-empty pot over medium heat. Sprinkle in 1/4 cup all-purpose flour, and stir until it turns golden and begins to smell toasted, 1 to 1 1/2 minutes.

4. 04

   Slowly whisk in 5 cups whole milk or half-and-half, 1/2 cup at a time, until no lumps of flour remain. Bring to a boil. Reduce the heat to medium-low and continue cooking, whisking frequently, until the sauce is thickened and clings to the back of a spoon, 5 to 7 minutes. You may need to adjust the heat to low to prevent the milk from boiling over.

5. 05

   Remove the pot from the heat. Add the remaining 5 cups cheese, 1 3/4 teaspoons kosher salt, and 1/4 teaspoon black pepper, and stir until the cheese is melted. Add the macaroni and stir to combine.

6. 06

   Transfer half of the macaroni and cheese to the baking dish and spread into an even layer. Sprinkle with half of the reserved cheese. Repeat layering the remaining macaroni and cheese and shredded cheese. Sprinkle paprika over the top if desired.

7. 07

   Bake until the mac and cheese is bubbling around the edges and the cheese on top is melted and golden brown in spots, about 10 minutes.

8. 08

   Make ahead: Cover the unbaked, assembled mac and cheese with aluminum foil and refrigerate for up to 2 days or freeze for up to 3 months. Thaw in the refrigerator overnight. Bake, still covered, at 350°F until heated through and bubbling around the edges, about 20 minutes. Uncover and bake until the cheese on top is golden brown, 15 to 20 minutes more.Storage: Refrigerate leftovers in an airtight container for up to 4 days. The mac and cheese will lose some of its creaminess upon refrigeration, add a splash of milk during reheating to loosen the sauce.
