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.)

  1. Add Topping – Spread into a baking dish, top with remaining lobster & breadcrumb topping.
  2. 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.

How to Store

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.
To prepare one day ahead: Store the topping (and extra lobster for the top) separately. Remove the baking dish from the fridge 45 minutes before baking. To heat, cover the baking dish with foil and bake covered for 20 minutes. Remove the foil and stir (you can add a bit of warm milk if needed to keep a creamy consistency). Top with the reserved lobster and topping and bake uncovered for an additional 10 minutes or until browned.

  1. Hey, I’m making this recipe tonight. What is light cream? Is that light cream cheese?? Please clarify! Thank you. I’m excited to cook it tonight.

    1. Hi Jenny, light cream is 18-30% milk fats. So you can use half and half in it’s place if you don’t have light cream.

  2. Fantastic! Followed the recipe exactly and we argued what amounts the three of us had taken as we all wanted more eyeing each others plates!5 stars

  3. This was delicious!! I followed it exactly and it came out fantastic. Next time I make it I will add more lobster or add some shrimp !! Yum5 stars

  4. I’ve made this several times – delicious! I’ve made it with lobster and shrimp. It’s my go to macaroni and cheese recipe when I splurge.5 stars

  5. Had to sub in shrimp. Was creamy and delectable. Didn’t have old bay, so looked up a copy cat recipe and used what I had. I can’t use black pepper, either. A touch of cayenne and ginger helped over come that. Def will make again. Shrimp Mac is a new fav for me.5 stars

  8. Delicious. Baked in oven in rectangular slow cooker crock. Kept warm in slow cooker on table for buffet. Everyone raved! Mild flavor so tasted lobster flavor.

    1. I would pre-cook and chop them similar to the lobster. If you try it I would love to hear how it turns out!

  9. This was fantastic! We cut it in half (but still used 2 small lobster tails) and took the advice of another reviewer and cooked the pasta in the same water the lobster was boiled in. So, so good.5 stars

  10. I have made this recipe twice now, once at Thanksgiving and most recently I made this as a side dish at a neighbors Christmas party. Both times it was amazing and everyone commented on how wonderful it was. If you are looking for a Lobster Mac and Cheese recipe, I highly recommend this one.5 stars
