This classic Cioppino seafood stew is a magnificent, high-protein dish that brings the fresh flavours of the coast to your kitchen. Inspired by the traditional fishermen's stews of San Francisco, this recipe features a vibrant tomato and white wine broth infused with fennel and aromatics. The combination of tender squid, meaty white fish, and fresh shellfish creates a sophisticated yet comforting meal that is perfect for a weekend dinner party or a special family treat.
To elevate the dish, we pair the savoury stew with crisp gremolata toasts. Rubbed with fresh garlic and topped with a zesty lemon-parsley butter, these toasts are ideal for soaking up the delicious juices. Using a mix of sustainable hake or cod makes this a versatile and healthy choice for anyone looking to increase their seafood intake. Serve in large bowls at the centre of the table for a truly sociable dining experience.

How to make Cioppino Seafood Stew with Gremolata Toasts
Back to contentsMince 2 of the garlic cloves. In a large pot over medium heat, heat oil. Add onion, fennel, celery, 1/2 teaspoons salt, and 1/4 teaspoons pepper and cook, stirring occasionally, until softened, 6 to 8 minutes. Add the minced garlic and red-pepper flakes. Continue to cook, stirring constantly, until garlic is golden and fragrant, 1 to 2 minutes more.
Reduce heat to medium-low and add squid. Cook, stirring occasionally, until squid is opaque and tender and the released juices reduce, 15 to 20 minutes. Add tomato paste and oregano and cook, stirring, 1 minute.
Add wine, raise heat to medium-high, and cook until cooking liquid is reduced by half, 5 to 7 minutes. Add tomatoes with their juice, bay leaves, clam juice, and stock. Bring to a boil, reduce to a simmer, and cook, covered, 30 minutes. Stir in 1/4 teaspoons each salt and pepper. Taste and adjust seasoning.
Meanwhile, in a small bowl, mix the butter, 1 tablespoon parsley, lemon zest, and 1/4 teaspoons salt together. Cut remaining garlic clove in half and rub the cut sides on the toasts. Spread the flavoured butter on the toasts.
When ready to serve, heat the pot to medium and add clams, cover, and cook for 3 minutes. Stir in the prawns and mussels. Arrange the fish on top of the stew, cover, and simmer until shellfish opens and fish and prawns are firm and opaque, about 5 minutes more. Discard bay leaves and stir in remaining 2 tablespoons parsley.
Serve cioppino immediately in large soup bowls with gremolata toasts alongside.
