Lobster mac and cheese is comfort food taken to its most luxurious extreme. Everything you love about classic mac and cheese — creamy sauce, tender pasta, golden breadcrumb topping — gets elevated to special-occasion status with the addition of sweet, succulent lobster meat. It is decadent, indulgent, and absolutely worth every calorie.
The cheese sauce here uses a blend of sharp cheddar for tang, Gruyère for creaminess and nutty depth, and a touch of cream cheese for silkiness. Folding in generous chunks of lobster right before baking means the shellfish stays tender and sweet rather than becoming rubbery. The breadcrumb topping is the finishing touch — golden, buttery, and crunchy against the creamy pasta below.
Ingredients
- 1 pound cavatappi or elbow macaroni
- 12 oz cooked lobster meat, cut into chunks
- 2 cups shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 1/2 cups whole milk
- 1 cup panko breadcrumbs mixed with 2 tablespoons melted butter
- 1 teaspoon Dijon mustard
Instructions
- 1
Preheat oven to 375°F. Cook pasta until 2 minutes shy of al dente, drain, and set aside.
- 2
Melt 3 tablespoons butter in a large saucepan over medium heat. Whisk in flour and cook for 1 minute. Gradually add milk, whisking constantly, until smooth and thickened, about 4-5 minutes.
- 3
Remove from heat and stir in the cheddar, Gruyère, and Dijon mustard until completely melted and smooth. Season with salt, pepper, and a pinch of cayenne.
- 4
Fold the pasta and lobster chunks into the cheese sauce. Pour into a greased 9x13 baking dish.
- 5
Top evenly with the buttered panko breadcrumbs.
- 6
Bake for 20-25 minutes until bubbling around the edges and golden on top. Let rest for 5 minutes before serving.

Tips & Storage
Pro Tips
Do not overcook the pasta in the initial boil — it will continue cooking in the oven.
If using frozen lobster tails, steam them for 5-6 minutes, then shock in ice water before removing the meat.
Add a tablespoon of sherry to the cheese sauce for an extra layer of flavor.
For an even more golden top, broil for the final 1-2 minutes, watching carefully.
Storage
Refrigerate covered for up to 3 days. The pasta absorbs sauce as it sits, which is normal.
Reheating
Reheat covered in a 350°F oven for 15-20 minutes. Add a splash of milk before reheating to restore creaminess.

Frequently Asked Questions
- What type of lobster should I use?
- Cold-water lobster tails (Maine or Canadian) have the sweetest, most tender meat. Pre-cooked lobster tails from the seafood counter are convenient and work well.
- Can I use a different pasta shape?
- Yes, shells, cavatelli, and penne all hold the cheese sauce well. Avoid long pasta like spaghetti.
