  • 2 cloves garlic minced
  • 150 ml heavy cream
  • 150 ml fish stock or broth
  • 50 g butter
  • 2 tbsp fresh parsley chopped
  • 1 tbsp olive oil
  • q.s. salt and pepper to taste
  • 100 g grated cheese Gruyère, Emmental, or Parmesan
  • q.s. breadcrumbs optional, for extra crunch

Equipment

  • Chef's knife
  • Cutting board
  • Large pot for boiling
  • Large skillet
  • Medium baking dish about 9x13 inches

Method
 

  1. Preheat your oven to 200°C (390°F).
  2. Peel and thinly slice the potatoes (about 1/8-inch thick) and parboil them in salted boiling water for 10 minutes.
  3. Drain the potatoes in a colander and let them steam dry.
  4. In a large skillet, heat olive oil and half the butter over medium heat; add chopped onion and garlic, cooking until soft.
  5. Add shrimp and mussels to the skillet, sauté for 2-3 minutes, then set aside.
  6. Pour fish stock into the skillet, scraping up browned bits, then stir in heavy cream; let simmer for 5 minutes, thickening slightly.
  7. Butter a baking dish; layer parboiled potato slices, cod fillet chunks, shrimp, and mussels, pouring two-thirds of the creamy sauce over the seafood.
  8. Sprinkle half of the fresh parsley, then add the final layer of potatoes and pour the remaining sauce over everything.
  9. In a bowl, mix grated cheese with breadcrumbs, then sprinkle on top; dot with remaining butter.
  10. Bake for 20-25 minutes until golden and bubbly.
  11. Let the gratin rest for 5-10 minutes before serving.
