01 - Preheat oven to 350°F. Line an 8-inch loaf pan with parchment paper and lightly coat with oil.
02 - Place fish fillets in a saucepan, cover with water, and simmer over low heat for 6–8 minutes until just cooked through. Drain thoroughly and flake into pieces using a fork.
03 - Whisk together eggs, heavy cream, crème fraîche, Parmesan, lemon zest, and lemon juice in a large bowl until smooth and well combined.
04 - Stir in chopped shallot, fresh dill, parsley, capers if using, and breadcrumbs until evenly distributed.
05 - Gently fold in flaked fish and chopped shrimp. Season generously with salt and black pepper.
06 - Transfer mixture to the prepared loaf pan. Smooth the surface evenly and drizzle with olive oil.
07 - Bake for 30–35 minutes until the center is set and the top develops a golden color.
08 - Allow to cool for at least 15 minutes before removing from the pan. Slice and serve warm or at room temperature, garnished with additional herbs and lemon wedges if desired.
