In a large pot of generously salted boiling water, cook the elbow macaroni or cellentani pasta until al dente. Drain thoroughly and set aside.

In a skillet, melt 1 tablespoon of butter over medium heat. Add the chopped lobster meat and seafood seasoning, cooking for 3 to 5 minutes until heated through. Remove the lobster from the skillet and set aside.

In the same pot used for pasta (or a clean large saucepan), melt the remaining 4 tablespoons of butter over medium heat. Whisk in the all-purpose flour until a smooth paste (roux) forms. Gradually pour in the whole milk while continuously whisking to prevent lumps, allowing the mixture to thicken. Stir in the heavy cream, onion powder, kosher salt, and freshly ground black pepper.

Reduce heat to low. Add the shredded sharp cheddar, Fontina, and grated Parmigiano Reggiano cheeses, stirring continuously until completely melted and the sauce is smooth and creamy.

Gently fold the cooked pasta and prepared lobster meat into the cheese sauce until everything is evenly coated. Transfer the mixture into a baking dish greased with non-stick cooking spray.
