A Creamier Take on Lobster Mac and Cheese
Unlike baked lobster macaroni and cheese recipes that can be dense or dry around the edges, our stovetop version stays creamy and smooth from start to finish. Gruyère and mascarpone create a rich, velvety sauce with enough depth to complement the lobster without overpowering its naturally sweet flavor, while cavatappi holds the sauce perfectly in every bite.
We’ve tested a few different versions of macaroni and cheese with lobster and found that cooking the dish entirely on the stovetop consistently delivers superior results. Both the lobster and pasta stay tender and the sauce remains smooth and silky. A handful of fresh chives adds a subtle, sweet onion note that brightens the dish without competing with the seafood.

Ingredient Notes and Substitutions
A few key ingredients make this recipe work – here’s what to know. A complete list with quantities is in the recipe card below.
- Pasta: Choose a short, ridged pasta that can hold plenty of sauce. Cavatappi is our favorite because its corkscrew shape catches the creamy cheese sauce, but shells or rotini will work too.
- Lobster: Lobster tails are a practical choice because they’re easy to find, often go on sale, and cook quickly. For a more budget-friendly version, substitute shrimp for some of the lobster (details below).
- Gruyère: Use young Gruyère, around 6 months old, for the smoothest melt and mild, nutty sweetness. Fontina is an acceptable substitute, but avoid sharp cheeses that overpower the delicate flavor of the lobster like cheddar or Parmesan.
- Mascarpone: Mascarpone gives the sauce its velvety texture and gentle milky sweetness. It melts in easily and softens the nuttiness of the Gruyère without competing with the lobster.
- Chives: Fresh chives add a subtle, sweet onion note that balances the richness of the cheese sauce. They also bring a little color to an otherwise creamy dish.
A Quick Look at Preparation
How to Make Lobster Mac and Cheese
Here’s how this dish comes together, along with a few tips for the best results. Full instructions are in the recipe card below.
This macaroni and cheese with lobster comes together in several steps, each one designed to build flavor. The lobster tails are simmered first, then the pasta is cooked in the same water to pick up a subtle layer of seafood flavor.


The cheese sauce starts with a simple roux of butter and flour, followed by warm milk whisked in gradually to create a smooth texture. Next the Gruyère is added, and as soon as it’s incorporated, the mascarpone is stirred in for richness and a soft, creamy finish.


To finish the dish, the cooked pasta, lobster, and fresh chives are folded gently into the sauce. Before serving, let the mac and cheese rest off the heat for about 5 minutes so the sauce can cool slightly and the flavors can come together.

This stovetop cooking method helps the lobster stay tender and sweet, and prevents the sauce from separating the way baked versions sometimes can.
Tips for Success
- Warming the milk before whisking it into the roux helps the sauce come together smoothly and lump-free.
- Grate your Gruyère just before using if possible. Pre-shredded cheese often contains anti-caking agents that can keep the sauce from melting as smoothly.
Serving Suggestions
- As a side dish: Serve lobster mac and cheese as a side dish with grilled filet mignon, strip steak, or steakhouse-style ribeye for a special occasion dinner.
- As a main course: Serve as an entrée with a crisp green salad dressed with a lemon vinaigrette to balance the richness of the sauce.
Lobster and Shrimp Variation
Lobster and shrimp share a naturally sweet flavor profile so they can work nicely together in this dish. You can substitute 3 ounces of large shrimp (31 to 40 per pound) for each lobster tail you want to replace. Cook the lobster first, then briefly poach the shrimp in the same water (1-1/2 minutes). You can also sauté them in butter if preferred.

Creamy Stovetop Lobster Mac and Cheese
Ingredients
- 2 or 3 lobster tails (5-ounces each)
- 12 ounces pasta, cavatappi, rotini, or shells
- 3-3/4 cups whole milk
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- Salt and freshly ground pepper
- 8 ounces Gruyère cheese, coarsely grated
- 6 ounces mascarpone cheese
- 2 tablespoons chopped fresh chives
Instructions
- Bring a large pot of generously salted water to a boil. Reduce the heat to a steady simmer, add the lobster tails, and cook until the shells are bright red and the meat is opaque, 4 to 5 minutes. Use tongs to transfer to a plate and let cool.
- Return the water to a boil. Add the cavatappi and cook until al dente according to package directions. Drain and set aside.
- When the lobster tails are cool enough to handle, remove the meat from the shells and cut it into bite-sized chunks. To remove the meat easily, use kitchen shears to cut through the top shell, then gently pull the shell apart.
- Warm the milk in a saucepan or microwave until hot but not simmering.
- Melt the butter in a large, heavy saucepan over medium heat. Add the flour and whisk until smooth. Continue cooking, whisking constantly, until the mixture is pale golden, about 3 minutes.
- Gradually whisk the warm milk into the flour mixture until smooth. Cook, whisking frequently, until the sauce thickens enough to coat the back of a spoon, 7 to 8 minutes. Season to taste with salt and pepper.
- Reduce the heat to low and stir in the Gruyère until melted. Add the mascarpone and stir until smooth and creamy.
- Add the cooked cavatappi, lobster meat, and chives. Stir gently until well combined. Remove from the heat and let stand for 5 minutes before serving.

Thanks for this great recipe! Made it tonight and it was delicious. I used frozen claw and knuckle meat since that’s what I had available, and penne pasta since I don’t have a corkscrew noodle style for my pasta machine. I also added 1-2 tablespoons of sour cream to get it used up. So glad I found this recipe; simple ingredients, nothing complicated, and so tasty!
Hi Jennifer,
We’re thrilled to hear you liked the mac and cheese. I’ll bet it was great with homemade pasta. Thanks for taking the time to leave a comment and for the tip about the sour cream.
