Main Ingredients

  • 12 oz (340 g) Elbow macaroni (or cavatappi)
  • ½ lb (225 g) Large shrimp, peeled & deveined
  • 3 Tbsp Unsalted butter
  • 2 Tbsp All‑purpose flour
  • 2 cups (480 ml) Whole milk
  • 1 ½ cups (170 g) Sharp cheddar cheese, shredded
  • 1 cup (110 g) Mozzarella cheese, shredded
  • ¼ cup (20 g) Parmesan cheese, grated
  • 2 Tbsp Cajun seasoning
  • 1 tsp Smoked paprika
  • ½ tsp Garlic powder
  • ¼ tsp Cayenne pepper
  • ½ tsp Salt
  • ¼ tsp Freshly ground black pepper
  • ½ cup Panko breadcrumbs

Instructions
 

Preparation

  • Cook macaroni according to package directions; drain and set aside. In a large bowl, toss shrimp with 1 tablespoon of Cajun seasoning, smoked paprika, garlic powder, cayenne pepper (if using), salt, and black pepper; set aside.

Cooking

  • In a large oven-safe skillet or Dutch oven, melt 2 tablespoons of butter over medium heat. Add the seasoned shrimp and cook for 2-3 minutes per side, until pink and cooked through; remove shrimp and set aside.
  • Add the remaining 1 tablespoon of butter to the skillet. Whisk in the flour and cook for 1 minute, stirring constantly, to create a roux.
  • Gradually whisk in the whole milk, ensuring no lumps form. Bring the mixture to a simmer, then reduce heat to low.
  • Stir in the sharp cheddar, mozzarella, Parmesan cheese, and remaining 1 tablespoon of Cajun seasoning until melted and smooth. Add the cooked macaroni and shrimp to the cheese sauce and stir to combine.
  • In a small bowl, melt 2 tablespoons of butter. Stir in the panko breadcrumbs until evenly coated. Sprinkle the buttered panko over the mac and cheese.
  • Bake in a preheated oven at 375°F (190°C) for 15-20 minutes, or until the topping is golden brown and bubbly.

Notes

For extra spice, increase the amount of cayenne pepper or add a dash of hot sauce to the cheese sauce. You can also add some diced bell peppers or onions to the skillet with the shrimp for added flavor and vegetables.
