Ingredients

• 12 oz elbow macaroni, uncooked
• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 3 cups whole milk, warmed
• 1 teaspoon Dijon mustard
• 1 teaspoon salt, plus more for pasta water
• ½ teaspoon black pepper
• 1 teaspoon sweet or smoked paprika
• 2 cups shredded sharp cheddar cheese
• 1 cup shredded Gruyère cheese
• 1 lb cooked lobster meat, chopped
• ½ cup grated Parmesan cheese, optional
• 1 cup panko breadcrumbs or plain breadcrumbs, optional
• 2 tablespoons melted butter, optional
• 2 tablespoons fresh parsley, chopped, optional

Instructions

1. Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Bring a large pot of salted water to a boil. Cook the elbow macaroni until just al dente, about 1 minute less than the package directions. Drain well and spread the pasta evenly in the prepared baking dish.
3. In a medium saucepan, melt the butter over medium heat. Add the flour and whisk continuously for 1 to 2 minutes to create a smooth roux.
4. Slowly whisk in the warmed milk. Continue cooking for 4 to 6 minutes, whisking often, until the sauce thickens and coats the back of a spoon.
5. Stir in the Dijon mustard, salt, black pepper, and paprika. Reduce the heat to low.
6. Add the cheddar and Gruyère cheese gradually, whisking until fully melted and smooth. Stir in the Parmesan cheese if using.
7. Gently fold the chopped lobster meat into the creamy cheese sauce.
8. Pour the lobster cheese sauce evenly over the macaroni. Stir gently so all of the pasta is coated.
9. For a crispy topping, combine the breadcrumbs with melted butter and sprinkle evenly over the dish.
10. Bake for 20 to 25 minutes, until the edges are bubbling and the topping is lightly golden. For a deeper golden crust, broil for 1 to 2 minutes while watching closely.
11. Let the baked lobster mac and cheese rest for 5 to 10 minutes before serving. Garnish with fresh parsley if desired.

Health and Nutrition Benefits

Lobster is a lean source of protein that can help make this comforting pasta dish more satisfying. It also provides important nutrients such as vitamin B12, zinc, selenium, and omega-3 fatty acids. Cheese and milk add calcium and protein, while using homemade cheese sauce lets you control the ingredients and flavor.

For a more balanced meal, serve lobster mac and cheese with steamed green beans, roasted broccoli, a fresh salad, or lemony asparagus.

Tips and Variations

• Replace lobster with cooked shrimp or crab for a delicious seafood mac and cheese variation.
• Add lightly steamed broccoli, peas, or spinach for extra vegetables.
• Use smoked paprika for a deeper, smoky flavor.
• Prepare the casserole up to one day ahead, cover, refrigerate, then bake when ready. Add 5 to 10 extra minutes to the baking time.
• For a lighter version, use 2% milk and reduce the cheese slightly.
• Serve with a crisp salad, roasted vegetables, or warm crusty bread.

This creamy lobster mac and cheese casserole is rich, cheesy, comforting, and guaranteed to make any dinner feel extra special.
