How to Make Creamy Crab Macaroni and Cheese
Step 1: Prepare the Pasta
Cook 16 oz of cavatappi pasta in salted boiling water until al dente.
Drain and set aside.
Step 2: Make the Cheese Sauce
In a saucepan, melt ½ cup unsalted butter over medium heat.
Whisk in ½ cup all-purpose flour, 1½ tsp seafood seasoning, ½ tsp garlic salt, ½ tsp ground mustard, and ¼ tsp black pepper.
Cook for 1-2 minutes.
Gradually whisk in 5 cups of whole milk, bringing the mixture to a gentle boil.
Reduce heat and simmer for 3-5 minutes until thickened.
Step 3: Add Cheeses
Stir in 2 oz of softened chive and onion cream cheese until melted.
Add 3 cups of shredded Cheddar and Monterey Jack cheese blend, stirring until smooth.
Step 4: Combine Pasta and Crab
In a large mixing bowl, combine the cooked pasta and 1 lb of jumbo lump crab meat.
Pour the cheese sauce over the mixture and stir until well combined.
Step 5: Assemble the Dish
Preheat the oven to 350°F (175°C). Grease a 13×9-inch baking dish.
Layer half of the pasta mixture into the dish, sprinkle with 1 cup of shredded cheese, add the remaining pasta mixture, and top with another cup of shredded cheese.
Step 6: Prepare the Topping
In a small bowl, mix 2 tbsp melted unsalted butter, ½ cup panko breadcrumbs, 1 tbsp grated Parmesan cheese, and ¼ tsp seafood seasoning.
Sprinkle the topping evenly over the casserole.
Step 7: Bake
Bake uncovered for 30-40 minutes, or until the top is golden brown and the edges are bubbly.
Garnish with 1 tbsp of chopped fresh Italian parsley before serving.
What to Serve It With
Green Salad: A crisp salad with a light vinaigrette balances the richness of the mac and cheese.
Steamed Vegetables: Broccoli, asparagus, or green beans make excellent side dishes.
Garlic Bread: Adds a crunchy contrast and is perfect for sopping up any extra cheese sauce.
White Wine: A chilled glass of Chardonnay or Sauvignon Blanc complements the seafood flavors.
Variations / Substitutions

Spicy Kick: Incorporate a pinch of cayenne pepper or diced jalapeños for heat.
Gluten-Free: Use gluten-free pasta and breadcrumbs to accommodate dietary needs.
Different Cheeses: Experiment with other cheese combinations like Fontina, Asiago, or Pepper Jack.
Storage & Leftovers
Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheating: Reheat individual portions in the microwave at 50% power to avoid drying out the crab meat.
