Method
Prepare the oven, pasta, and sauce
- Preheat the oven to 375°F.
- Coat a 9x13-inch baking dish with nonstick cooking spray.
- Bring the 4 quarts water to a boil in a large pot.
- Add the macaroni and 1 tablespoon salt to the boiling water, and cook for 2 minutes less than the package directions for al dente, usually 6-8 minutes.
- Drain the macaroni.
- While the pasta cooks, melt 4 tablespoons butter in a large saucepan over medium heat.
- Whisk in the flour.
- Cook for 1 minute.
- Gradually whisk in the milk.
- Cook, whisking often, for 5-7 minutes until the sauce thickens enough to coat a spoon.
- Remove from the heat and stir in the dry mustard, black pepper, and remaining 1/2 teaspoon salt.
- Stir in the cheddar and Gruyere a handful at a time until melted and smooth.
Assemble and bake
- Fold the drained macaroni and lobster into the cheese sauce.
- Transfer the mixture to the prepared baking dish.
- Melt the remaining 2 tablespoons butter.
- Toss the melted butter with the panko.
- Scatter the topping evenly over the macaroni.
- Bake for 20-25 minutes until the topping is golden and the sauce bubbles around the edges.
- Rest for 10 minutes before serving.
Notes
For a smooth sauce, stir in the cheeses a handful at a time until melted. Refrigerate leftovers for 3-4 days; freezing is possible, though the sauce texture may change. For a gluten-free adaptation, use gluten-free pasta, flour, and breadcrumbs.
