Step 1: Prepare the Pasta
Bring a large pot of salted water to a boil. Add the pasta and cook until al dente according to package instructions. Drain and set aside.
Step 2: Prepare the Lobster
If using whole lobster tails, steam or boil them for about 5-7 minutes until the shells turn bright red. Let them cool slightly, then remove the meat and chop into bite-sized pieces.
In a small skillet, melt 2 tablespoons of butter over medium heat. Add the lobster meat, Old Bay seasoning, and lemon juice. Sauté for about 2 minutes to enhance the flavor. Remove from heat and set aside.
Step 3: Make the Cheese Sauce
In a large saucepan, melt 4 tablespoons of butter over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant.
Sprinkle in the flour and whisk continuously for about 1-2 minutes to cook out the raw flour taste.
Slowly pour in the milk and heavy cream, whisking constantly to prevent lumps.
Stir in the Dijon mustard, smoked paprika, salt, and pepper. Continue cooking over medium heat until the sauce thickens, about 5 minutes.
Reduce the heat to low and gradually add the cheddar, Gruyère, and Parmesan cheese, stirring until fully melted and smooth.
Step 4: Combine Everything
Add the cooked pasta to the cheese sauce, stirring to coat every piece in that creamy goodness.
Gently fold in the sautéed lobster meat, ensuring it’s evenly distributed throughout the mac and cheese.
Step 5: Make the Crispy Topping
In a small bowl, mix the panko breadcrumbs, melted butter, garlic powder, salt, and Parmesan cheese. Stir to combine.
Step 6: Assemble and Bake
Preheat your oven to 375°F (190°C).
Transfer the mac and cheese mixture to a greased 9x13-inch baking dish.
Sprinkle the breadcrumb topping evenly over the top.
Bake uncovered for 20-25 minutes or until golden brown and bubbly.
Remove from the oven and let it rest for 5 minutes before serving. Garnish with fresh parsley and enjoy!
