Why You’ll Love This Lobster Mac and Cheese Recipe

I probably don’t need to convince you to make this mac and cheese, but here are some reasons just in case:

  • Cheesy. Mac and cheese should be loaded with cheesy goodness, and this recipe won’t disappoint.
  • Creamy. This mac and cheese is creamy without being soupy. I’m drooling just thinking about it!
  • Lobster loaded. We’re not skimping on lobster. If you’re making lobster mac and cheese, you probably want those big chunks of fresh lobster meat, and that’s exactly what you’re getting.
  • Easy. You might think mac and cheese is a feat only for professional chefs. But making mac is absolutely for all those fellow home cooks out there!
  • Big pan = leftovers! Enough said.

Lobster Mac and Cheese Ingredients

  • Elbow pasta – you can use a different type of short pasta but elbows are classic!
  • Hand-grated mozzarella cheese – I recommend hand-grating all of your cheeses. This helps the cheese melt evenly and smoothly. Mozzarella adds stringy goodness!
  • Hand-grated sharp cheddar cheese – sharp cheddar adds a rich flavor.
  • Hand-grated Emmental or Jarlsberg cheese – Emmental or Jarlsberg are relatively inexpensive Swiss cheeses. You can use gruyere cheese, but it’s more expensive. Any of these cheese will add a buttery, nutty flavor that complements the lobster.
  • Hand-grated parmesan cheese – parmesan or Parmigiano-Reggiano and lobster are like PB&J! It’s a great garnish on top of your mac at the end of the baking process.
  • Cooked lobster meat – you can steam your own lobster but I recommend getting pre-cooked lobster meat which can usually be found at your grocery store or local fish market.
  • Whole milk – whole milk helps us get that creamy finish!
  • Half and half – some half and half adds a bit more indulgence than just whole milk alone.
  • All-purpose flour – flour creates a roux.
  • Butter – butter creates a roux.
  • Chives – chives, garnished on top, add a pop of freshness and brightness.

How to Make Lobster Mac and Cheese

Lobster mac and cheese at home is the BEST type of lobster mac and cheese!

  1. Prepare.

    Lightly grease a 9×13” pan. Preheat oven to 350 degrees.

  2. Pasta.

    In a large pot, boil your elbows for the cook time on the box minus 1 minute for extra al-dente pasta. Drain. Add 1 tablespoon of butter and toss to coat.

  3. Begin roux.

    In a separate medium pan over low heat, add the remaining 4 tablespoons of butter. Let melt. Increase heat to medium, add flour and whisk until incorporated.

  4. Add milk.

    Slowly add milk, and then half and half, whisking them into the flour mixture. Add salt and pepper to taste.

  5. Heat.

    Whisk for about 6-12 minutes over medium heat (depending on how cold your ingredients were when you started) until it passes the wooden spoon test. Stir constantly!

  6. Wooden spoon test.

    The wooden spoon test will help check whether your roux has thickened. When the roux is steaming hot and about to simmer, you’ll feel a bit of resistance as the roux thickens. Use your finger to trace a line on the back of a wooden spoon. If there is a creamy coating on the back of the spoon and the line remains strong and visible (not faint), the roux is thick enough and it’s done! See video for visual instructions.
    Perform the wooden spoon test to check whether the mac and cheese roux has thickened enough.

  7. Add cheese.

    When roux has thickened, turn heat off and add the mozzarella, Emmental (or Jarlsberg), and sharp cheddar (NOT the parmesan). Stir until the cheese melts.

  8. Combine.

    Pour the cheese mixture into the pasta and toss. Add about 75% of the lobster. Toss.

  9. Pan.

    Pour pasta mixture into your pan, smoothing out into an even layer.

  10. Bake.

    Bake for 25 minutes. With about 7 minutes left, sprinkle parmesan cheese and remaining lobster, and finish baking. Serve with snipped chives!

Lobster Mac and Cheese Expert Tips

  • For the best results, I suggest manually grating all of your cheeses if possible. Pre-grated or shredded cheese often contain an anti-caking agent, which might cause the cheese to separate from the other components in your macaroni and result in a less creamy result.
  • Opt for regular mozzarella —avoid using fresh mozzarella.
  • I use the coarse setting on a cheese grater.
  • If you’d rather steam your own lobsters, place the lobsters into a big pot with two inches of boiling water. Steam them, covered, in the boiling water for approximately 20 minutes. Afterward, crack and measure out 1 pound of meat. Consult your fishmonger for advice on the number of lobsters to purchase, taking into consideration the season, lobster shell type (hard or soft), and available sizes!
  • Both Emmental and Jarlsberg cheeses belong to the Swiss cheese category. While gruyere is an option, Emmental and Jarlsberg are more budget-friendly choices that still offer amazing flavor.

Variations & Substitutions

  • Use a different type of short pasta like cavatappi or shells.
  • Sprinkle 1-2 cups of breadcrumbs on the top of the mac after you add the parmesan cheese.
  • Bake your mac longer for a more golden brown top and thicker interior.
  • Add in a tablespoon or two of truffle oil for truffle lobster mac and cheese.
  • Top with different herbs or spices like tarragon, basil, chervil or saffron.

What to Serve With Lobster Mac and Cheese

Serve lobster mac and cheese in so many different ways. It can be a side dish or main dish depending on your mood! You can serve with a simple vegetable like Broiled Asparagus, or even as a steakhouse dinner with a Pan-Seared Tenderloin Steak! I also love this Green Goddess Salad that’s healthy and fresh, a perfect match for the mac.

Storage

  • To store: Store in the fridge, covered once cooled, for up to 4 days.
  • To reheat: Reheat mac and cheese right in the pan (or in a separate dish), covered with foil at 350 degrees until hot. Reheat time depends on how much mac you’re reheating.
  • To freeze: You can freeze lobster mac and cheese for up to 3 months. Defrost in the fridge before reheating.

Frequently Asked Questions (FAQs)

Is this lobster mac and cheese creamy?

Yes, it’s creamy and cheese…oh my!

Can I use pre-shredded/grated cheeses?

I recommend hand-grating all of your cheeses. Pre-grated/shredded cheese includes an anti-caking agent which can cause the cheese to separate from the other ingredients in your mac and not melt as smoothly. It’s not a mandatory but definitely recommended. I use the coarse setting of a cheese grater.

Can you steam your own lobsters instead of buying precooked lobster meat?

Yes, you can! Add lobsters to a large pot with 2 inches of boiling water. Steam in boiling water, covered, for 20 minutes. Crack and measure out 1 pound of meat. Ask your fish monger how many lobster to buy. It depends on the season (hard/soft shell and lobster sizes available!).
