Green Chile Mac and Cheese

1 Cook the macaroni very al dente: Bring a large pot of salted water to a boil (a tablespoon of salt for every 2 quarts of water). Add the macaroni pasta. Return to a rolling boil, and boil, uncovered, for about 2 minutes less than the cooking time given on the pasta box instructions.

The pasta should be mostly cooked, but still a little too firm to eat; it will complete its cooking in the oven.

When the pasta is ready, drain it into a colander and run cold water over it to stop the cooking.

2 Preheat the oven to 400°F.

3 Make a roux with butter and flour: In an ovenproof pot such as a casserole or Dutch oven, heat the butter over medium heat. When the butter is melted and bubbly, stir in the flour to make a roux. Cook this, stirring often, for about 2 minutes. You don’t want the roux to brown.

4 Slowly whisk in milk, then the cheeses: Add the milk to the roux, a little at a time, stirring constantly so that lumps do not form. Whisk until smooth.

Stir in the cheeses third at a time, stirring to incorporate after each addition.

5 Stir in pasta, chiles, corn, lime juice, salt: Add the macaroni, chiles, corn and lime juice and stir until well combined. Taste for salt, add a teaspoon, less or more, if needed.

6 Top with panko and bake: Top the mac and cheese with panko or breadcrumbs. Bake uncovered for 25 to 30 minutes at 400°F, or until the breadcrumbs are lightly browned.

Remove from oven and let cool for 10 minutes before serving.
