This dish features tender lobster pieces folded into creamy, cheesy macaroni topped with flavorful herbed breadcrumbs. The cheese sauce combines sharp cheddar, Gruyère, and Parmesan with spices for depth. The breadcrumb topping is toasted with fresh parsley, chives, lemon zest, and a touch of garlic powder to add crispness and aroma. After baking until golden and bubbling, it offers a decadent main course ideal for pescatarian menus and comfort food lovers alike.
The first time I made lobster mac and cheese was for my husband's birthday. I'd been saving those two beautiful lobster tails in the freezer for something special, and the way the kitchen smelled when that herbed butter hit the breadcrumbs made me realize this wasn't just dinner anymore. We stood around the oven watching the top turn golden brown, neither of us able to wait that extra five minutes I'd planned for resting.
Last winter my sister came over when she was feeling down, and I made this without telling her there was lobster involved. Her face when she took that first bite and discovered the chunks of sweet seafood tucked into the creamy noodles was absolutely priceless. Sometimes the best meals are the ones that surprise you.
Ingredients
- 340 g (12 oz) elbow macaroni: The curves catch the cheese sauce perfectly, and I always cook it just shy of al dente since it'll finish in the oven
- 2 cooked lobster tails: About 300 g of meat works beautifully, and chopping it into bite-sized pieces means every forkful gets some lobster love
- 3 tbsp unsalted butter: Use this for the roux base because controlling the salt matters when you're adding salty cheeses later
- 3 tbsp all-purpose flour: This creates the silky foundation for your cheese sauce, and whisking constantly prevents any lumps from forming
- 720 ml (3 cups) whole milk: Whole milk gives you that rich restaurant-quality texture that skim milk just can't deliver
- 120 ml (½ cup) heavy cream: The secret ingredient that makes the sauce feel impossibly luxurious and helps it stay creamy after baking
- 170 g (6 oz) sharp cheddar cheese: Sharp gives you that classic cheese flavor we all crave in mac and cheese
- 85 g (3 oz) Gruyère cheese: This melts beautifully and adds a nutty depth that pairs incredibly well with lobster
- 55 g (2 oz) Parmesan cheese: Finely grate it yourself because the stuff in the shaker can has anti-caking agents that make the sauce grainy
- 1 tsp Dijon mustard: You won't taste mustard, but it enhances the cheese flavor the way a pinch of salt enhances chocolate
- ½ tsp smoked paprika: This adds a subtle smoky note that bridges the gap between the seafood and the cheese
- 60 g (2 oz / 1 cup) fresh breadcrumbs: Making your own from day-old bread gives you better texture and control over the seasoning
- 2 tbsp unsalted butter: For toasting the breadcrumbs until they're golden and fragrant
- 2 tbsp fresh parsley: Finely chopped brings a bright pop of color and fresh flavor to cut through all that richness
- 1 tbsp fresh chives: Their mild onion flavor plays so nicely with both the lobster and the cream sauce
- 1 tsp lemon zest: This bright little spark makes everything taste lighter and fresher
Instructions
- Preheat your oven:
- Get it to 190°C (375°F) and grease a 2-liter baking dish with butter so nothing sticks later.
- Cook the pasta:
- Boil those elbow macaroni in salted water until just al dente, drain well, and set aside.
- Start your roux:
- Melt 3 tablespoons butter in a medium saucepan over medium heat, whisk in the flour, and cook for one full minute while stirring constantly.
- Build the sauce:
- Gradually pour in the milk and cream, whisking like your life depends on it, then simmer for 3 to 4 minutes until it thickens enough to coat the back of a spoon.
- Add all that cheese:
- Remove from heat and stir in the cheddar, Gruyère, Parmesan, mustard, paprika, salt, and pepper until everything's melted and smooth.
- Combine everything:
- Fold in the cooked macaroni and chopped lobster meat, then pour the whole glorious mixture into your prepared baking dish.
- Make the topping:
- Melt 2 tablespoons butter in a skillet, add the breadcrumbs, and cook for 2 to 3 minutes until golden and fragrant.
- Finish the crumbs:
- Stir in the parsley, chives, lemon zest, and garlic powder, then sprinkle this mixture evenly over the mac and cheese.
- Bake until bubbly:
- Pop it in the oven for 20 to 25 minutes until the top is golden brown and the sauce is bubbling up around the edges.
- The hardest part:
- Let it rest for 5 minutes before serving so the sauce has a chance to set slightly.
My friend Lisa claims this is the dish that made her finally understand why people spend money on good cheese. We served it at our annual holiday potluck last year, and honestly, nobody talked about anything else for the rest of the night.
Making Ahead
You can assemble everything up to 24 hours in advance, but hold off on the breadcrumbs until you're ready to bake. Cover the dish tightly and store it in the refrigerator, then add another 10 minutes to the baking time since it'll be cold going into the oven.
Cheese Swaps
Fontina works beautifully instead of Gruyère if you want something milder, and Swiss cheese brings a lovely nutty flavor. Just avoid pre-shredded cheese since the anti-caking coating prevents it from melting smoothly into that silky sauce we're after.
Serving Suggestions
A crisp green salad with an acidic vinaigrette cuts through the richness perfectly. Keep the sides simple since this dish is definitely the star of the show.
- A glass of buttery Chardonnay complements both the lobster and the cheese sauce
- Steamed broccolini with lemon adds a fresh green element to the plate
- Garlic bread is unnecessary here but honestly who am I to stop you
Every time I make this, I'm reminded that some dishes are worth every bit of effort and every single calorie. Enjoy every bite of this indulgent comfort food.
