This classic béchamel-based mac and cheese is loaded to the hilt with cheese. Not only do we pack as much cheese as we can into the sauce itself, but we then mix the cooked pasta and cheese sauce with additional grated cheese, for tiny pockets of stretchy, melty bits throughout. One of the benefits of this method is that you can get enhanced browning in the oven, especially on the bottom and sides of the baking dish, thanks to the flour and butter in the sauce.
Why It WorksThe cheesiest. Read the Whole Story
- Extra grated cheese folded into the pasta and cheese sauce creates tiny pockets of stretchy, melted, intensely flavored cheese.
- A buttery panko bread crumb topping bakes up crisp and with a light crunchiness.
- Kosher salt
- 1 pound (450g) elbow macaroni
- 7 tablespoons (105g) unsalted butter, divided
- 2 tablespoons (16g) all-purpose flour
- 2 cups (475ml) milk
- 1 1/2 pounds (680g) grated sharp Cheddar cheese (see note above)
- 1 teaspoon (5ml) hot sauce, such as Frank's Red Hot
- 1/2 (2g) teaspoon mustard powder
- 1/4 (1g) teaspoon garlic powder
- 1/2 pound grated Gruyere cheese (see note above)
- 1 cup (2 ounces; 55g) panko bread crumbs
Preheat oven to 400°F. In a medium pot of salted boiling water, cook elbow macaroni until just shy of al dente, about 2 minutes less than package cooking time. Drain, then transfer pasta to large mixing bowl and toss with 2 tablespoons (30g) butter until butter is melted and pasta is evenly coated. Set aside.
In a large saucepan, melt 2 tablespoons (30g) butter over medium-high heat (do not allow it to brown). Add flour and whisk to form a paste. Continue to cook, stirring, until raw flour scent is gone, about 1 minute. Whisking constantly, add milk in a thin, steady stream, whisking constantly and thoroughly and getting into all corners of the pan to maintain a homogeneous texture. Sauce will initially become very thick, then get very thin once all the milk is added.
Heat, stirring, until sauce comes to a simmer and begins to thicken slightly. Working in increments, whisk in Cheddar cheese until a smooth emulsified cheese sauce forms. Whisk in hot sauce, mustard powder, and garlic powder. Season with salt if necessary.
Scrape cheese sauce into pasta and mix until evenly coated. Let cool slightly, then add grated Gruyere and mix well. Scrape pasta into a 9- by 13-inch baking dish and smooth surface to an even layer.
Add panko to a small mixing bowl. Melt the remaining 3 tablespoons (45g) butter, then add to panko and mix until evenly coated. Season with salt. Scatter panko all over surface of mac and cheese in an even layer. Bake on top rack until browned and bubbling, about 45 minutes (ovens can vary, check often to prevent top from burning).
Let mac and cheese rest 15 minutes, then serve. Leftover mac and cheese can be refrigerated for up to 5 days; it reheats surprisingly well in the microwave or oven.
