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.

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:

  1. Cook pasta – Make the topping & set aside. Boil the pasta al dente (firm).
  2. Make Sauce – Make a roux with butter, flour, & seasonings, then create the cheese sauce (per recipe below.)

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.

Notes

This recipe uses cooked lobster meat. Use tails or a whole lobster if you prefer. You can cook just tails by broiling them (broiled lobster tail recipe here) or boiling in water below. Two to three small tails should be enough but you can add extra if you'd like.
No Lobster?! No Problem. Substitute other favorites seafood in this recipe such as lump crab meat, shrimp, scallops, salmon or a combination!
To Boil Lobster Tails for Meat Bring a large pot of heavily salted water to a boil. Place 3 lobster tails (approximately 3-3.5 oz each) in the boiling water and let simmer 3-4 minutes or just until cooked through. The thickest part of the meat should reach 140°F. Check them early to ensure they do not overcook.

  1. Recipe says cook time is 40 min but bake for only 20-25. Is 40 the total for the pasta, sauce, lobster and final casserole?

    1. The cooking time counts for 20 minutes of baking and 20 minutes to prepare the sauce while the pasta is boiling.

  2. I’m going to attempt to make this for my sisters bday celebration next month! I’m super excited!!! Thank you for sharing :0)

    1. This recipe is an absolute favorite of mine! Glad you enjoyed it as much as I do, Judith!!

    1. Hi Mark, for best results I would serve immediately after baking. If you want to prep ahead you could try prepping up to Step 8 and set aside and just combine everything in the casserole dish before baking. We would love to hear how it turns out for you!
