Description

Seafood Gratin brings together succulent ocean treasures baked under a golden, crispy breadcrumb blanket that melts in your mouth. Your dinner guests will savor each creamy, cheesy bite of this classic coastal comfort dish.


Ingredients

Scale

Seafood:

  • 1 pound seafood mix (shrimp, scallops, and crab)

Dairy:

  • 4 tablespoons butter
  • 1 cup heavy cream
  • ½ cup milk
  • 1 cup grated Gruyere or cheese blend

Aromatics and Seasonings:

  • 3 cloves garlic, minced
  • 1 medium onion, finely chopped
  • 2 tablespoons parsley, chopped
  • 1 tablespoon lemon juice
  • ½ cup breadcrumbs
  • Salt and pepper to taste

Instructions

  1. Warm your oven to a precise 375°F, ensuring the rack sits in the center position for even heating.
  2. Melt 4 tablespoons of butter in a large skillet over medium heat. Sauté 1 finely chopped medium onion and 3 minced garlic cloves until they turn translucent and fragrant, about 3-4 minutes.
  3. Add 1 pound of seafood mix to the skillet, stirring gently to coat with butter. Cook for exactly 5 minutes, then remove from heat.
  4. Whisk together 1 cup heavy cream, ½ cup milk, 1 tablespoon lemon juice, salt, and pepper in a separate mixing bowl until smooth.
  5. Fold the sautéed seafood into the cream mixture, then stir in ½ cup of grated Gruyere cheese.
  6. Grease a baking dish thoroughly. Pour the seafood mixture into the dish, spreading it evenly.
  7. Sprinkle the remaining ½ cup of cheese and ½ cup breadcrumbs across the top of the gratin.
  8. Slide the dish into the preheated oven and bake for 25-30 minutes until the top turns a golden brown and the edges bubble.
  9. Remove from oven and let rest for 5 minutes. Garnish with 2 tablespoons of freshly chopped parsley before serving.

Notes

  • Always use fresh seafood for the best flavor and ensure it’s properly cleaned before cooking.
  • Select a mix of seafood like shrimp, scallops, and white fish to create depth and variety in the gratin.
  • Grate your own cheese instead of using pre-shredded for a smoother, more even melting texture.
  • Toast breadcrumbs separately in a pan with a little butter before sprinkling on top to enhance their golden crunchiness.
