Print Recipe

A creamy, golden-baked seafood dish with shrimp and scallops in a rich cheese sauce.

Ingredients

Scale
  • 1/2 lb shrimp, peeled and deveined
  • 1/2 lb scallops (or chunks of white fish like cod)
  • 2 tbsp butter
  • 2 cloves garlic, minced
  • 1 tbsp flour
  • 1 cup milk
  • 1/2 cup heavy cream
  • 1/2 cup grated Gruyère or mozzarella
  • 1/4 cup grated Parmesan cheese
  • Salt & pepper to taste
  • 1/2 tsp paprika
  • 1/4 tsp nutmeg (optional)
  • Fresh parsley for garnish
  • Optional: splash of white wine for added depth

Instructions

  1. Melt butter and sauté garlic until fragrant. Stir in flour and cook for 1 minute.
  2. Slowly whisk in milk and cream, then add paprika, nutmeg, salt, and pepper. Cook until thickened, then stir in half the cheese.
  3. Lightly season shrimp and scallops, then quickly sear in a hot pan for 1–2 minutes per side.
  4. In buttered ramekins or a baking dish, add seafood, then pour over the cheesy cream sauce. Top with remaining cheese and Parmesan.
  5. Bake at 400°F (200°C) for 15–18 minutes until hot and golden brown. Broil for 1–2 minutes for extra bubbly topping. Let rest 5 minutes, garnish with parsley, and serve.

Notes

  • Do not overcook the seafood—just sear lightly before baking.
  • For extra flavor, add a splash of white wine to the cream sauce.
  • Let the gratin rest for 5 minutes after baking for better texture.
