Preheat your oven to 375°F (190°C).
In a large pot, cook the macaroni according to the package instructions until al dente. Drain and set aside.
In a separate saucepan, melt the butter over medium heat. Once melted, add the flour and whisk continuously for about 2 minutes until the mixture turns slightly golden.
Gradually pour in the milk while whisking constantly to create a smooth roux. Continue whisking until the mixture thickens and comes to a gentle boil.
Reduce the heat to low and stir in the garlic powder, onion powder, paprika, salt, and pepper. Allow the flavors to meld for a few minutes.
Add the shredded cheddar cheese to the sauce, reserving a small amount for topping. Stir until the cheese is fully melted and the sauce is smooth and creamy.
Fold in the cooked lobster meat and the drained macaroni, ensuring they are evenly coated with the cheese sauce.
Transfer the mixture to a greased baking dish, spreading it out evenly. Sprinkle the remaining shredded cheese on top.
Place the baking dish in the preheated oven and bake for approximately 20-25 minutes, or until the cheese is golden and bubbling.
Once cooked, remove the dish from the oven and let it cool for a few minutes. Garnish with fresh parsley for an added touch of freshness and color.
Serve the Lobster Macaroni and Cheese while still warm and savor each delectable bite.
