½teaspoonfreshly ground black pepper(or more to taste)
1 ½packages(24 ounces) dried cavatelli(or ziti, penne, or any short pasta)
Instructions
Preheat the oven to 400 F. Butter a shallow 4-quart baking dish.
Bring a large pot of water to a boil, salt it generously, and let the water return to a boil.
Meanwhile, make the panko topping: Melt the butter in a small saucepan over low heat or place it in a medium-size microwave-safe dish and heat it in a microwave oven until melted, about 15 seconds. Add the panko and the Parmesan and stir until well combined. Set the panko topping aside.
Make the sauce: Melt the butter in a large, heavy saucepan over medium heat. Whisk in the flour and red pepper flakes, if using. Cook, stirring, until the flour is blond in color, about 4 minutes. Gradually whisk in the milk. Increase the heat to medium-high and let it come to a simmer, whisking frequently. Reduce the heat to medium-low and let the sauce simmer until it starts to thicken, about 5 minutes. Add the cream, grated cheese, Parmesan, mustard, salt, and black pepper, stirring until everything is smooth. Taste for seasoning, adding more salt and/or black pepper as necessary.
Add the pasta to the boiling water and cook it until barely al dente (follow the package directions, but stop a minute or two before the pasta is completely tender). Set aside 1 cup of the pasta cooking water, then drain the pasta.
Whisk the reserved pasta cooking water into the cheese sauce, combining it thoroughly. Add the pasta to the cheese sauce and stir to combine. Spoon the pasta mixture into the prepared baking dish. There will appear to be a lot of sauce. Some of it will be absorbed into the pasta as it cooks, and in my book, saucy is better than dry.
Sprinkle the panko topping evenly over the pasta and bake it until golden and bubbling, 30 to 40 minutes. Let the pasta sit for a few minutes before serving.
Notes
You can prepare the macaroni and cheese up to the point of baking and let it sit at room temperature for up to 2 hours. If you want it to keep longer, you can refrigerate it for up to 1 day. Either let the macaroni and cheese come to room temperature before baking or, if you’re taking it straight from the refrigerator, add about 15 minutes to the baking time.Also, you can wrap the macaroni and cheese very well with aluminum foil and freeze it for up to 3 months. Either defrost it in the fridge (this takes about 24 hours) or add about 30 minutes to the baking time— leave the foil on the casserole for the first 30 minutes of baking so the top doesn’t get too brown.No matter what, if you’re going to refrigerate or freeze the dish before baking, hold off on the panko topping. It’s best if you add it just before baking.
