Lobster mac and cheese is one of those uber-fancy once-in-a-while entrees on a restaurant menu.
Why not make the same rich and creamy, delish dish at home for both amazing flavor and lower price?

Easy Lobster Mac and Cheese
- The reviews are in! Homemade lobster mac and cheese rivals any of the restaurants near or far. Make it at home and impress the guests!
- It’s rich, creamy and delicious.
- While this dish isn’t cheap, it’s a great way to stretch 2 small lobster tails to feed a crowd!
- Use freshly cooked lobster, lobster tails, or even lobster meat.
- No Lobster?! No problem! Substitute canned crab, lump crab meat, or even cooked shrimp in place of lobster. Many stores carry frozen cooked lobster meat which would work well in this recipe too.
Grill some garlic bread and serve!
What’s in Lobster Mac & Cheese?
PASTA: This recipe uses cavatappi (corkscrew) pasta but any medium shape with ridges or tubes to hold the sauce works well.
SEAFOOD: Lobster has a sweet, buttery flavor that is perfectly complemented by the rich flavors of the cheese. But if lobster isn’t easily found, try smoked salmon, crab, scallops, or shrimp.
SAUCE: This is made with a roux using butter and flour (but don’t worry, it’s easy) and adding milk/light cream. Once thickened the cheeses are stirred in for a rich cheese sauce.
How to Make Lobster Mac and Cheese
Gourmet has never been this easy to make:
- Cook pasta – Make the topping & set aside. Boil the pasta al dente (firm).
- Make Sauce – Make a roux with butter, flour, & seasonings, then create the cheese sauce (per recipe below.)
- Add pasta – Add sauce to pasta with half the lobster. Stir to combine.
- Add Topping – Spread into a baking dish, top with remaining lobster & breadcrumb topping.
- Bake – Bake until the top is golden brown, garnish, & serve!
Tips for a Creamy Lobster Mac and Cheese
- Shred the cheeses from a block, pre-shredded cheeses have additives and do not melt well.
- Remove the sauce from the heat before stirring in the cheese. If overheated the cheese can separate or cause a grainy sauce.
- Ensure the lobster is cooled before adding to the pasta.
- Do not overcook or the pasta will become dry.
What Goes with Lobster Mac & Cheese?
Choose elegant sides that have a tangy flavor to them to offset the richness of the lobster mac and cheese. Roasted Asparagus with Tarragon Vinaigrette, Balsamic Roasted Brussels Sprouts, a crunchy salad like Easy Arugula Salad, and of course some Homemade Focaccia Bread for dipping into the cheesy sauce!
How to Store
Keep leftover lobster mac and cheese in an airtight container in the refrigerator for about 3 days. Reheat it on the stove and add a little milk or cream to thin it out a bit. Pasta does not freeze well, so enjoy lobster mac and cheese while it’s fresh!

Superb! Better than any restaurant! Hubby says it’s the best lobster mac n cheese he’s ever eaten!
I made this with leftover lobster meat from our NYE dinner and it was sooo good! I used gruyere and sharp cheddar cheese and made it exactly as written. My whole family loved it and now they won’t want to eat mac and cheese any other way! 😂
Was a lovely Christmas dinner with a very crispy crunchy salad with chickpeas too only change was adding some garlic powder. Made in a 9×13 glass pyrex. Sooo good we ate luke kings and queens I assembled it in the morning and baked it at my host’s house later that day following your make in advance instructions. Perfect!
Only had 12 ounces of pasta butter. It kept it from drying out in the oven and it was creamy and delicious.
We had this for Christmas Dinner, it was fabulous. It does make a big serving. Can it be frozen?
I haven’t tried freezing this recipe so I can’t say for sure. Let us know how it goes!
