Method
Make the mac and cheese
- Heat the oven to 350°F.
- Grease a 9x13-inch baking dish.
- Cook the macaroni in a large pot of boiling water seasoned with 1 tablespoon of the salt until 2 minutes shy of the package directions for al dente.
- Drain the macaroni.
- While the macaroni cooks, melt the butter in a large saucepan over medium heat.
- Whisk in the flour and cook for 1 minute.
- Gradually whisk in the milk and cook, whisking often, until the sauce thickens enough to coat the back of a spoon, 5 to 7 minutes.
- Remove the saucepan from the heat.
- Whisk in the 3 cups of cheddar, the remaining 1/2 teaspoon salt, the dry mustard, and the black pepper until smooth.
- Stir the drained macaroni into the sauce.
- Transfer the mixture to the prepared baking dish.
Top and bake
- Combine the remaining 1 cup cheddar, the panko, and the olive oil in a bowl.
- Scatter the mixture evenly over the macaroni.
- Bake until the topping is golden and the sauce bubbles around the edges, 20 to 25 minutes.
- Let rest for 10 minutes before serving.
Notes
For an extra-crisp topping, spread the panko mixture evenly over the macaroni. Refrigerate leftovers for 3 to 4 days; freezing is fine, though the sauce may be less creamy after thawing. For a gluten-free version, use gluten-free macaroni and breadcrumbs.
