Ingredients You’ll Need
For the Mac & Cheese:

2 tbsp unsalted butter
2 tbsp all-purpose flour
2 cups whole milk (warm)
1 cup heavy cream
2½ cups sharp cheddar cheese, shredded
1 cup Gruyère cheese, shredded (or use mozzarella for a milder taste)
½ cup Parmesan cheese, grated
1 tsp Dijon mustard
½ tsp garlic powder
½ tsp smoked paprika
Salt and black pepper to taste
1½ cups cooked lobster meat (claw and tail, chopped into bite-size pieces)
1 tbsp lemon juice
For the Topping:
¾ cup panko breadcrumbs
2 tbsp unsalted butter, melted
2 tbsp Parmesan cheese
1 tsp chopped parsley (for garnish)
Tools You’ll Need
Large pot for boiling pasta
Medium saucepan for cheese sauce
Baking dish (9×13 or similar size)
Whisk
Mixing spoons
Measuring cups and spoons
Small bowl for breadcrumb topping
Step-by-Step Instructions
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil.
Add macaroni and cook until just al dente (about 1-2 minutes less than package directions).
Drain and set aside. Do not overcook—it will continue cooking in the oven.
Step 2: Make the Roux
In a medium saucepan, melt 2 tbsp of butter over medium heat.
Add flour and whisk constantly for 1-2 minutes to form a smooth paste (this cooks out the raw flour taste).
Step 3: Build the Cheese Sauce
Slowly whisk in the warm milk and cream, stirring until smooth.
Simmer for 3-4 minutes, stirring often, until slightly thickened.
Stir in Dijon mustard, garlic powder, smoked paprika, salt, and black pepper.
Reduce heat to low, then add cheddar, Gruyère, and Parmesan cheese.
Stir until melted and smooth.
Step 4: Add the Lobster & Pasta
Gently stir the cooked pasta into the cheese sauce.
Add chopped lobster meat and lemon juice, folding everything together.
Taste and adjust seasoning as needed.
Step 5: Transfer to Baking Dish
Pour the lobster mac and cheese into a greased 9×13 baking dish.
Smooth the top with a spatula.
Step 6: Make the Topping
In a small bowl, mix panko breadcrumbs, melted butter, and Parmesan cheese.
Sprinkle evenly over the top of the mac and cheese.
Step 7: Bake to Golden Perfection
Preheat oven to 375°F (190°C).
Bake uncovered for 20-25 minutes, or until bubbly and the top is golden brown.
If needed, broil for an extra 1-2 minutes for a crispier topping (watch closely!).
Step 8: Garnish & Serve
Remove from oven and let sit for 5 minutes before serving.
Sprinkle with chopped parsley for a fresh finish.
Serve warm and enjoy the creamy, cheesy, lobster-loaded goodness.
Tips for Success
Use Real Cheese – Pre-shredded cheese has additives. Grate your own for the smoothest sauce.
Don’t Overcook Pasta – Slightly underdone pasta will absorb the sauce perfectly in the oven.
Balance the Richness – A splash of lemon juice keeps the dish from being too heavy.
Mix Lobster Last – Fold it in gently to avoid breaking the delicate pieces.
Customize the Cheese – Try Fontina, Monterey Jack, or White Cheddar for different flavors.
Serving Suggestions
As a Main Dish – Pair with a green salad or roasted asparagus.
As a Side – Perfect next to grilled steak, chicken, or baked fish.
With Bread – Serve with garlic bread or crusty rolls to soak up every bit of sauce.
Fancy Dinner – Add a drizzle of truffle oil before serving for extra elegance.

Microwave: Use a microwave-safe dish and reheat in 30-second intervals, stirring between each.
