Method
Prepare the pan
- Heat the oven to 375°F.
- Coat a 9x13-inch baking dish with nonstick cooking spray.
Cook the pasta
- Bring a large pot of water to a boil.
- Add 1 tablespoon of the kosher salt and the macaroni.
- Cook for 6 minutes or 2 minutes less than the package directions.
- Drain the macaroni well.
Make the cheese sauce
- 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 bring to a gentle simmer.
- Cook for 5–7 minutes, whisking often, until thick enough to coat the back of a spoon.
- Remove the saucepan from the heat.
- Stir in the Dijon mustard, dry mustard, paprika, black pepper, and remaining 1/2 teaspoon kosher salt.
- Add the Gouda and cheddar in handfuls, stirring until melted.
Assemble and bake
- Stir the drained macaroni and lobster into the cheese sauce.
- Transfer the mixture to the prepared baking dish.
- Toss the panko with the melted butter.
- Scatter the panko evenly over the macaroni.
- Bake for 15–20 minutes, until the topping is golden and the sauce is bubbling at the edges.
- Let the macaroni and cheese rest for 10 minutes before serving.
Notes
For the best texture, cook the pasta just until the stated doneness so it does not overcook in the oven. Refrigerate leftovers for up to 3 days; freezing is not recommended because the cheese sauce may separate. For a gluten-free variation, use gluten-free pasta, flour, and panko.
