Ingredients
  

  • 8 oz elbow macaroni
  • 2 tbsp butter
  • 1 tbsp all-purpose flour
  • 1½ cups whole milk
  • 1 cup heavy cream
  • 1 tsp Dijon mustard
  • ½ tsp garlic powder
  • ½ tsp smoked paprika
  • 1 tsp salt and black pepper to taste
  • 1 cup sharp cheddar cheese shredded
  • 1 cup Gruyère cheese shredded

  • 1 tbsp parsley chopped, optional garnish

Instructions
 

  • Preheat oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.
  • Cook macaroni until al dente. Drain and set aside.
  • In a saucepan, melt butter over medium heat. Stir in flour and whisk 1 minute to form a roux.

  • Stir in Dijon, garlic powder, paprika, salt, and pepper. Mix in cheeses until melted and smooth.
  • Fold in cooked seafood and macaroni. Transfer to baking dish.
  • Combine breadcrumbs with olive oil and sprinkle over top.
  • Bake for 25–30 minutes until golden, bubbly and hot in the center (165°F). Garnish with parsley, if desired.

Notes

For extra decadence, mix in a little truffle oil or top with extra Parmesan and broil for a crispy finish. Refrigerate leftovers within 2 hours and eat within 3 to 4 days; reheat to 165°F.
