  • Prep Time: 15 minutes
  • Cook Time: 30 minutes
  • Total Time: 45 minutes
  • Servings: 4


  • 2 cups of dry Macaroni
  • 6 oz. Claw Crab Meat
  • 8 oz. Shrimp, peeled and deveined
  • 8 oz. Sour Cream
  • 4 Tablespoons Butter
  • 2 Tablespoons Flour
  • 1 Spring Onion, finely chopped
  • 1 can Evaporated Milk
  • 8 oz. block Sharp White Cheddar Cheese, grated
  • 4 oz. block Mozzarella Cheese, grated
  • ¼ cup Panko Bread Crumbs
  • Salt and Black Pepper, to taste


  1. Prep Your Station: Start by boiling a pot of salted water. Preheat your oven to 375°F (190°C).
  2. Cook the Macaroni: Pour the 2 cups of dry macaroni into the boiling water. Cook according to the package instructions until al dente. Once done, drain and set aside.
  3. Seafood Sauté: In a skillet, melt 2 tablespoons of butter over medium heat. Add the chopped spring onion, and sauté until translucent. Introduce the shrimp and crab meat to the skillet and cook until the shrimp turn pink. Season with salt and pepper, then remove from heat and set aside.
  4. Cheese Sauce Delight: In a saucepan, melt the remaining butter over medium heat. Whisk in the flour and cook for a minute to form a roux. Gradually add the evaporated milk, whisking constantly to avoid lumps. Once the mixture thickens, reduce the heat to low. Stir in the grated sharp white cheddar and mozzarella until smooth and creamy. Season with salt and pepper. Now, fold in the sour cream.
  5. Combine & Layer: Mix the macaroni and seafood sauté into the cheese sauce until everything is well-coated. Transfer this heavenly mixture to a baking dish.
  6. Crispy Topping: Sprinkle the panko bread crumbs over the top of the mac and cheese for that crispy contrast we all love.
  7. Bake to Perfection: Place your dish in the preheated oven and bake for about 20 minutes or until the top turns golden brown.
  8. Serve & Savor: Let your Seafood Mac and Cheese rest for a few minutes out of the oven. Then, serve and watch faces light up with pure joy.

The Secrets Behind Perfect Seafood Mac and Cheese:

  • Fresh Ingredients: Always choose fresh seafood. The freshness of the crab and shrimp elevates the entire dish.

Serving Suggestions:

  • Serve with a light green salad drizzled with vinaigrette to balance the richness of the dish.
  • A chilled glass of white wine or sparkling water with a lemon wedge complements the creamy textures beautifully.

Frequently Asked Questions (FAQs):

  • Can I use other types of seafood? Absolutely! Lobster or scallops would be fantastic additions or substitutes.
  • Is it freezer-friendly? Yes, store in an airtight container, and it can be frozen for up to 2 months.
  • What’s the best cheese substitute? Gruyère or Fontina can be used in place of cheddar for a different taste.
