Creamy Crab Mac and Cheese

Creamy Crab Mac and Cheese pairs tender lump crab with elbow macaroni and a smooth three-cheese sauce. Sharp white cheddar adds bold flavor, Gruyère brings a nutty finish, and mozzarella keeps every bite creamy and satisfying. Old Bay, Dijon, smoked paprika, and fresh chives complement the crab without hiding its delicate sweetness.

A buttery Parmesan-panko topping bakes into a light golden crust, giving the dish just enough contrast while the center stays rich and saucy. Although it feels special enough for holidays or entertaining, the method is straightforward and made with familiar ingredients. Serve it as a comforting main dish or an elevated side alongside a crisp salad or roasted vegetables. It is warm, generous, and just luxurious enough to make an ordinary dinner feel a little more memorable.

Recipe Yield: 6 servings

INGREDIENTS

12 oz elbow macaroni
8 oz cooked lump crab meat, drained and picked over
1 ½ cups shredded sharp white cheddar
1 cup shredded Gruyère
½ cup shredded mozzarella
3 tbsp unsalted butter
3 tbsp all-purpose flour
2 cups whole milk
1 cup heavy cream
1 tsp Dijon mustard
1 tsp Old Bay seasoning
½ tsp garlic powder
½ tsp smoked paprika
1 tsp sea salt
½ tsp black pepper
2 tbsp chopped fresh chives
1 cup panko breadcrumbs
2 tbsp melted butter
2 tbsp grated Parmesan cheese

INSTRUCTIONS

1. Preheat and cook the pasta:
Preheat the oven to 375°F. Lightly butter a 9×13-inch baking dish. Cook the macaroni for 1 minute less than the package directions for al dente. Drain well and set aside.

2. Make the roux:
Meanwhile, melt 3 tbsp butter in a large saucepan or Dutch oven over medium heat. Whisk in the flour and cook for 1–2 minutes until smooth and lightly bubbling.

3. Build the creamy base:
Gradually whisk in the milk and heavy cream. Cook, whisking often, until the sauce gently simmers and coats the back of a spoon, about 4–6 minutes.

4. Season the sauce:
Stir in the Dijon mustard, Old Bay seasoning, garlic powder, smoked paprika, sea salt, and black pepper until evenly combined.

5. Melt the cheeses:
Remove the pan from the heat. Add the cheddar, Gruyère, and mozzarella a handful at a time, stirring gently after each addition until melted and smooth.

6. Fold in the pasta and crab:
Add the cooked macaroni and stir gently to coat. Carefully fold in the crab meat and chopped chives, keeping the larger crab pieces intact.

7. Prepare the topping:
In a small bowl, mix the panko breadcrumbs, melted butter, and Parmesan until evenly coated.

8. Bake until golden:
Transfer the mac and cheese to the prepared baking dish. Sprinkle the breadcrumb topping evenly over the surface. Bake for 18–20 minutes, until the edges are bubbly and the topping is lightly golden.

9. Rest and serve:
Let the Creamy Crab Mac and Cheese rest for 5 minutes before serving. Garnish with additional chives if desired.

Helpful Tips to Perfect This Recipe

• Drain the crab thoroughly: Excess liquid can thin the cheese sauce. Pick through the crab carefully for shells while keeping the larger pieces intact.
• Grate the cheese fresh: Cheese shredded directly from the block melts more smoothly and helps prevent a grainy sauce.
• Watch the final bake: Remove the dish once the edges are bubbling and the topping is golden. Overbaking can dry the sauce and make the crab less tender.
