3 tablespoons all-purpose flour
3 cups whole milk, warmed
1 teaspoon Dijon mustard

1 teaspoon paprika

Cheese

How to Make Oven-Baked Lobster Mac and Cheese

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil.

Cook the macaroni until al dente according to package directions.

Drain and set aside.

Step 2: Make the Roux

In a large saucepan, melt the butter over medium heat.

Whisk in the flour and cook for 1–2 minutes until lightly golden.

Step 3: Add the Milk

Slowly pour in the warm milk while whisking continuously.

Cook until the mixture thickens enough to coat the back of a spoon.

Step 4: Season the Sauce

Stir in:

Dijon mustard
Salt
Black pepper
Paprika

Mix thoroughly.

Step 5: Add the Cheese

Reduce heat to low.

Gradually add the cheddar and Gruyère cheeses.

Stir until completely melted and smooth.

Step 6: Combine Pasta and Lobster

Fold the cooked pasta into the cheese sauce.

Gently stir in the chopped lobster meat.

Mix until evenly distributed.

Step 7: Transfer to Baking Dish

Lightly grease a baking dish.

Pour in the lobster mac and cheese mixture.

Sprinkle Parmesan cheese over the top if desired.

Step 8: Bake

Preheat oven to 375°F (190°C).

Bake uncovered for 20–25 minutes until golden brown and bubbling around the edges.

Step 9: Rest and Serve

Allow the dish to rest for 5–10 minutes before serving.

This helps the sauce set while maintaining its creamy texture.

Storage Instructions

Allow leftovers to cool completely before storing.

Refrigerate in an airtight container for up to 3 days.

Because of the rich cheese sauce, the pasta will thicken slightly when chilled.

Reheating Tips

For the best texture:

Reheat in the oven at 325°F (165°C)
Add a splash of milk or cream
Cover with foil to prevent drying out

Microwave reheating works well for individual portions.

Expert Tips for Success

Don’t Overcook the Pasta

Cook only to al dente since the pasta continues cooking in the oven.

Use Warm Milk

Warm milk blends smoothly into the roux and prevents lumps.

Fold Lobster Gently

Avoid overmixing to keep the lobster pieces intact.

Freshly Grate the Cheese

Freshly grated cheese melts more smoothly than pre-shredded varieties.

Let It Rest

A brief resting period allows the sauce to thicken slightly for perfect serving consistency.
