Sauce Ingredients

  • ½ cup unsalted butter (divided) 6 tablespoons for cooking, remaining for topping
  • 1 small onion (diced)
  • 2 cloves garlic (minced)
  • ½ cup all-purpose flour
  • ½ cup chicken or vegetable broth
  • 3 ½ cups milk (warmed to 115 degrees F)
  • 12 ounces Gruyere cheese (shredded) High-quality cheese recommended
  • 8 ounces cheddar cheese (shredded)
  • 1 cup Parmesan cheese (grated, divided) Use all but 2 tablespoons in the sauce
  • 2 teaspoons kosher salt
  • ½ teaspoon black pepper
  • ½ teaspoon nutmeg
  • 1 ½ pounds cooked lobster meat Freshly cooked or thawed if frozen

Topping

  • ¼ cup panko breadcrumbs
  • 1 Tablespoon remaining Parmesan cheese
  • Fresh chopped parsley (for garnish)

Instructions
 

Preparation

  • Preheat the oven to 375 degrees F. Spray a 4-quart casserole dish with cooking spray and set aside.
  • Cook the pasta in salted water according to the package directions until al dente. Drain and set aside.

Cooking the Sauce

  • In a medium saucepan, melt 6 tablespoons of butter over medium heat.
  • Add the diced onion and cook for 4-5 minutes until soft and translucent.
  • Stir in the minced garlic and sauté for 30 seconds, until fragrant.
  • Sprinkle in the flour and cook over low heat for 2 minutes, whisking constantly, until it turns golden.
  • Whisk in the broth while scraping the bottom of the pan for any brown bits.
  • Then, still whisking, pour in the warmed milk. Bring to a gentle simmer over medium heat, cooking until the mixture thickens and becomes smooth.
  • Remove the saucepan from heat, then add the Gruyere, cheddar, all but 2 tablespoons of Parmesan, salt, pepper, and nutmeg. Stir until all the cheese has melted and is combined.
  • Add the cooked macaroni and lobster to the sauce and stir well to coat.
  • Transfer the mixture to the prepared casserole dish.

Topping and Baking

  • Melt the remaining butter and mix it into the panko breadcrumbs and remaining Parmesan cheese, then sprinkle this mixture on top of the mac and cheese.
  • Bake for 15-20 minutes, or until the sauce is bubbly and the top is golden brown.
  • Garnish with fresh chopped parsley and serve hot.

Notes

Serve hot from the oven for best flavor and texture. Can be enjoyed as a main dish or side. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave. Consider adding spices for additional flavor and using freshly shredded cheese for better melting.
