Add pasta to a large pot of boiling water and cook to almost al dente, about 4-5 minutes.

Drain and set aside.

Preheat oven to 400 degrees.

Add 4 tbsp butter to a saucepan over medium heat.

Melt then add onion and garlic and cook until softened.

Add flour, stirring to combine and let cook a minute.

Then whisk in milk slowly until smooth.

Bring to a boil then reduce heat and simmer until thick.

Season with salt, pepper, and nutmeg and remove from heat.

Stir in cooked lobster {sometimes I add shrimp too}, reserving the meat from two lobster claws for garnish.

Pour into a greased 9X13 baking dish.

In a small bowl, mix together breadcrumbs, 2 tbsp melted butter, and Parmesan cheese.

Sprinkle on top of macaroni.

Bake for 15 minutes, until golden and bubbly.

Top with lobster claw meat for a garnish and serve warm.
