Ingredients

  • 1 (16 ounce) package elbow macaroni cooked 2 minutes less than al dente, drained and rinsed with cold water
  • 7 tablespoons butter divided
  • ¾ pound medium shrimp peeled, deveined and chopped into ½ inch pieces
  • ½ cup Italian seasoned panko bread crumbs
  • 1 cup diced yellow onion
  • 2 teaspoons minced fresh garlic
  • cup all-purpose flour
  • 3 cups whole milk
  • teaspoon ground nutmeg
  • ½ teaspoon Old Bay Seasoning
  • 1 ½ teaspoons kosher salt more or less, to taste
  • ¾ teaspoon freshly ground black pepper more or less, to taste
  • 1 ⅓ cup grated Parmesan cheese 4 ounces
  • 1 ⅓ cup shredded Swiss cheese 5 ⅓ ounces
  • 1 ⅓ cup shredded sharp cheddar cheese 5 ⅓ ounces
  • ½ pound cooked lump crab meat
  • chopped fresh parsley optional garnish

Instructions

  • Preheat your oven to 400 degrees . Spray a 3 quart baking dish with cooking spray; set aside.
  • Begin cooking your macaroni according to package directions (2 minutes less than al dente). Drain in a colander and rinse with cold water after cooking.
  • While macaroni is cooking, melt 1 tablespoon of the butter in a large skillet over medium high heat.  Add shrimp and cook, stirring constantly, just until pink on both sides (about 3 minutes).  Remove shrimp with a slotted spoon and transfer to a plate. Set aside.
  • In a 6 quart Dutch oven or large pot over medium heat, melt the remaining 6 tablespoons of butter.  Transfer 2 tablespoons of the melted butter to a medium bowl and toss with the panko bread crumbs.
  • Add diced onions and garlic to melted butter in the pot and cook until softened, about 3 to 4 minutes, stirring constantly.
  • Add flour and stir constantly until a paste is formed.
  • Slowly pour in milk. Stir until smooth and there are no lumps.
  • Bring to a simmer and simmer until thickened (about 1 minute), stirring constantly.
  • Season with salt, pepper, nutmeg and Old Bay Seasoning. Stir to combine.
  • Remove pot from burner.  Add cheeses and stir until cheeses are melted and smooth.  Fold in macaroni, shrimp and crab meat.
  • Transfer to the prepared 3 quart baking dish and spread evenly.
  • Sprinkle evenly with buttery panko bread crumb mixture.
  • Bake (uncovered) for 15 to 20 minutes, or until bread crumb topping is golden brown and sauce is bubbling around edges.
  • Sprinkle with chopped fresh parsley when serving, if desired.

Notes

To store:  Allow to reach room temperature and store in an airtight container in the fridge for up to 3 days.  When reheating, you may need to add a couple of tablespoons of milk, as the macaroni will continue to absorb the sauce.
