Lobster Mac and Cheese

Lobster mac and cheese (or anything with lobster really) tends to feel like those dishes that are reserved for special occasions or that might be too difficult to whip up at home. But I’m telling you, this lobster mac could not be easier! It’s rich, it’s cheesy, it’s the kind of stick to your ribs comfort food that will turn any day around. We love our classic Baked Mac and Cheese but this one is great as a full meal. I love this dish for cold weather months (and of course for special occasions as well). There’s just something so good about a bubbly baked version of mac and cheese that I can’t get enough of. The butter, tender lobster pairs so perfectly with the creamy four cheese blend. The texture, the taste, the buttered breadcrumbs on top, what’s not to love!

Make mac and cheese for every meal with more recipes like this Instant Pot Buffalo Chicken Mac & Cheese or creamy Bacon Mac and Cheese!

What kind of lobster is best for a recipe like this?

I like to use pre cooked lobster to save time and effort. You can ask the meat counter at your local supermarket and they’ll know exactly what you’re talking about. Imitation lobster should not be used. If you want to cook your own lobster tails, choose a cold water variety like Maine lobster for something with a sweet and buttery flavor that pairs perfectly with the rich, creamy cheese sauce!

How To Make Lobster Mac and Cheese

  • Preheat. Preheat the oven to 350°F. Lightly butter a 9×13 inch casserole dish and set aside.
  • Boil. Bring a pot of water to a boil and cook the macaroni according to package directions. Drain and set aside.
  • Whisk. In a large pot, melt 2 tbsp butter. Once melted, stir in the flour. Whisk to combine and cook for 1 minute to create a roux.
  • Add. Slowly add in the milk and heavy whipping cream. Whisk to combine. Season with a pinch of salt and pepper. Bring to a boil and lower heat to simmer for 10 minutes, stirring occasionally.
  • Sprinkle. Remove the pan from the heat and stir in the shredded cheeses, 3-4 handfuls at a time, until the sauce is smooth.
  • Pour. Pour the sauce and the lobster into the pasta and stir to combine. Pour the lobster mac into the prepared baking dish and spread out evenly.
  • Melt. In a small bowl, melt 2 tbsp of butter. Add the panko breadcrumbs to the bowl and stir. 
  • Top. Top the lobster mac and cheese with an even layer of breadcrumbs.Add a sprinkling of the green onions over top and place into the oven on the center rack.
  • Bake. Bake for 15 minutes until the cheese sauce is bubbling.
  • Serve. Garnish with additional green onions and enjoy!

Storing Lobster Mac and Cheese

Once cooled, store any leftover mac and cheese in an airtight container in the fridge for up to 4 days. Reheat in the microwave or oven until warmed through. Be VERY careful not to overheat it, or you’ll dry out the pasta and make the lobster meat rubbery. 

Ingredients Notes for Lobster Mac and Cheese

  • Macaroni –  I like to use traditional elbow macaroni here but any kind of short pasta will do.
  • Butter – Salted or unsalted, divided between the cheese sauce and the breadcrumb topping.
  • Flour – This will be combined with the butter to make a roux which helps thicken the cheese sauce.
  • Milk – Whole milk is the best in recipes like this but you can use 2% if you’ve got that. 
  • Heavy Whipping Cream – A combination of heavy cream and milk give the best consistency for our cheese sauce.
  • Cream Cheese – Full fat, softened to room temperature for easier mixing.
  • ShreddedCcheese – I used a blend of cheddar, gruyere, and havarti. You can use any combo of cheeses that are your personal favorite! I do recommend using the cream cheese, as well as either a white or yellow cheddar. Then pick at least one more cheese like a gruyere, asiago, parmesan, or even fontina.
  • Lobster – You can use pre-cooked lobster for this recipe to save yourself a bit of work and time. Don’t be tempted to use imitation lobster, it is not as good and not actually lobster!
  • Breadcrumbs – You want the panko style of breadcrumbs. These are thicker and give a heartier texture.
  • Green Onion – About 3 stalks, diced. 
  • Optional Spices – I personally keep seasonings simple in this recipe with just salt and pepper. That is our preference to let the lobster shine! However, you can use whatever seasonings you love! Good additions would be smoked paprika, Cajun seasoning, or even a pinch or two of Italian seasoning.
