  • Unsalted butter: lets you control seasoning and ensures a clean creamy foundation for the sauce
  • All-purpose flour: thickens the béchamel smoothly without lumps measure carefully to avoid a gluey texture
  • Whole milk plus half and half: combines creaminess with structure in the sauce room temperature helps prevent curdling when mixed
  • A pinch of nutmeg: adds warmth and complexity to the cheese sauce so don’t skip this touch

Instructions

Build The Base:
Preheat your oven to 400 degrees Fahrenheit and prepare a 3-quart baking dish with butter or cooking spray to prevent sticking and promote browning. Set aside.
Prep The Topping:
In a small bowl combine panko breadcrumbs, melted butter and grated Parmesan cheese. This mixture will crisp nicely on top to provide texture contrast.
Cook The Pasta:
Bring a large pot of salted water to a vigorous boil. Add your pasta and cook according to package directions until just al dente meaning the pasta has a slight bite. Drain and reserve a quarter cup of pasta water to adjust sauce later if needed.
Combine The Cheese:
While pasta is cooking, mix your shredded Gruyere, sharp cheddar, and white cheddar in a large bowl. This blends cheese flavors evenly and is ready to add to the sauce quickly.
Make The Cheese Sauce:
In a large pot or Dutch oven, melt butter over medium low heat. Stir in the flour and cook for approximately two minutes to form a roux which removes the raw flour taste and thickens the sauce. Slowly whisk in the whole milk in a steady stream to avoid lumps then add the half and half gradually. Stir in nutmeg, mustard powder, garlic powder, and pepper. Bring this to a boil then reduce heat to low and gently simmer, stirring often until the sauce thickens and is smooth.
Melt The Cheese:
Remove the pot from heat and add half the cheese mixture stirring until completely melted. Stir in remaining cheese until silky and incorporated creating a luscious sauce.
Combine Pasta And Lobster:
Add the drained pasta to the cheese sauce and stir to coat. Fold in half the lobster meat carefully to keep pieces intact. If sauce feels thick add reserved pasta water a little at a time. Taste and add salt and pepper to your liking.
Assemble The Dish:
Transfer the cheesy lobster macaroni mixture evenly into the baking dish. Sprinkle remaining lobster pieces on top then add the breadcrumb topping for a nice crust.
Bake To Perfection:
Place the baking dish in the oven and bake for 20 to 25 minutes until bubbly and golden on top. Watch carefully to avoid overbaking which dries out the mac and cheese.
How To Cook Lobster Tails:
It is best to cook the lobster tails a day ahead to save time. Boiling or baking both work well. Boil lobster tails in heavily salted water about one minute per ounce until internal temperature reaches 135 degrees Fahrenheit. Cool in ice water and remove meat carefully. Alternatively bake tails brushed with butter and seasoning at 450 degrees for about 8 to 10 minutes and then cool and remove meat. This advance step guarantees juicy tender lobster in your mac and cheese.

Ingredient Swaps

Feel free to use elbow macaroni or shells if cavatappi is unavailable the key is that it grabs sauce. Substitute Monterey Jack or mozzarella for the third cheese if you prefer a milder melt. For a dairy-free version try a mix of dairy-free cheeses and plant milk with a thickener like cornstarch.

Serving Ideas

Serve this lobster mac and cheese with a simple green salad dressed lightly with lemon vinaigrette to cut through richness. A crisp white wine like Sauvignon Blanc pairs wonderfully with the seafood and creamy cheese.
