Method
Cook the macaroni
- Heat the oven to 350°F.
- Coat a 9x13-inch baking dish with cooking spray.
- Bring a large pot of water to a boil.
- Add the 2 teaspoons kosher salt and 1 pound elbow macaroni, and cook for 7–8 minutes, until just al dente.
- Drain the macaroni well.
Make the cheese sauce
- Melt 4 tablespoons of the unsalted butter in a large saucepan over medium heat.
- Whisk in the all-purpose flour and cook for 1 minute.
- Gradually whisk in the whole milk and cook, whisking often, for 5–8 minutes, until the sauce thickens and coats the back of a spoon.
- Remove the saucepan from the heat.
- Stir in the dry mustard, 3/4 teaspoon kosher salt, black pepper, and sharp cheddar cheese until the cheese is melted.
Assemble and bake
- Stir the drained macaroni into the cheese sauce.
- Transfer the mixture to the prepared baking dish.
- Melt the remaining 2 tablespoons unsalted butter.
- Toss the melted butter with the panko breadcrumbs.
- Sprinkle the panko mixture evenly over the macaroni.
- Bake uncovered for 20–25 minutes, until bubbling at the edges and golden on top.
- Rest for 10 minutes before serving.
Notes
For the smoothest sauce, whisk the milk in gradually and freshly shred the cheddar so it melts evenly. Refrigerate leftovers for up to 4 days; freeze for up to 2 months. For a gluten-free version, use gluten-free pasta, flour, and breadcrumbs.
