Cioppino is a hearty San Francisco-born seafood stew built on a tomato-wine broth, loaded with whatever the day’s catch offers—typically Dungeness crab, clams, mussels, shrimp, and firm white fish. This version, inspired by the classic Italian-American fishermen’s stew, layers deep flavor from fennel, garlic, and red pepper flakes, then finishes with fresh herbs and a squeeze of lemon. It’s a showstopping one-pot meal that feels special but comes together in about an hour, perfect for a weekend dinner or a festive gathering.
Ingredients
- 1/4 cup (60 ml) olive oil
- 1 large yellow onion, diced (about 1 1/2 cups / 200 g)
- 1 fennel bulb, trimmed and thinly sliced (about 1 cup / 130 g), fronds reserved for garnish
- 4 cloves garlic, minced
- 1/2 teaspoon red pepper flakes (adjust to taste)
- 1 cup (240 ml) dry white wine, such as Sauvignon Blanc or Pinot Grigio
- 1 (28-ounce / 794 g) can crushed tomatoes
- 3 cups (720 ml) seafood stock or clam juice
- 1 bay leaf
- 1 teaspoon dried oregano
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon black pepper
- 1 pound (450 g) firm white fish fillets (cod, halibut, or sea bass), cut into 2-inch chunks
- 1 pound (450 g) large shrimp, peeled and deveined (tails on or off)
- 1 pound (450 g) mussels, scrubbed and debearded
- 1 pound (450 g) Manila or littleneck clams, scrubbed
- 1 cooked Dungeness crab (about 2 pounds / 900 g), cleaned and cracked into pieces (or 1 pound / 450 g lump crabmeat)
- 1/4 cup (15 g) fresh parsley, chopped
- 2 tablespoons fresh lemon juice, plus lemon wedges for serving
Instructions
- Heat the olive oil in a large Dutch oven or heavy pot over medium heat. Add the onion, fennel, and a pinch of salt. Cook, stirring occasionally, until softened and translucent, about 8–10 minutes.
- Add the garlic and red pepper flakes; cook for 1 minute until fragrant. Pour in the white wine, scraping up any browned bits from the bottom. Let the wine simmer for 2–3 minutes, until slightly reduced.
- Stir in the crushed tomatoes, seafood stock, bay leaf, oregano, salt, and black pepper. Bring to a boil, then reduce heat to low and simmer uncovered for 20 minutes to meld the flavors.
- Add the fish chunks to the broth. Gently push them down so they are mostly submerged. Cook for 3–4 minutes, until the fish is just opaque and flakes easily. (Fish is safe at 145°F / 63°C, the USDA FSIS safe minimum.)
- Add the shrimp, mussels, and clams. Cover the pot and cook for 5–7 minutes, until the mussels and clams have opened and the shrimp are pink and cooked through. Discard any that remain closed.
- Gently fold in the crab pieces (or lump crabmeat) and heat for 2–3 minutes, just until warmed through. Be careful not to break the crab.
- Remove the bay leaf. Stir in the parsley and lemon juice. Taste and adjust seasoning with salt and pepper.
- Ladle the cioppino into large bowls, making sure each gets a share of seafood and broth. Garnish with reserved fennel fronds and serve with lemon wedges on the side.
Tips
- Use a variety of seafood: The beauty of cioppino is flexibility. Swap in scallops, calamari, or lobster if you like. Just adjust cooking times—scallops and calamari need only 2–3 minutes.
- Don’t overcook the fish: Add the fish in order of firmness; dense fish like cod can go in first, while delicate sole should be added last. Keep the heat at a gentle simmer, not a rolling boil, to avoid breaking the fish.
- Make it ahead: The broth can be made a day in advance and refrigerated. Reheat gently, then add the seafood just before serving—this keeps everything fresh and perfectly cooked.
- Substitute for seafood stock: If you can’t find seafood stock, use chicken broth or water with a splash of clam juice. The flavor will be slightly different but still delicious.
Serving Suggestions
Serve cioppino with crusty sourdough bread or garlic bread for dipping into the rich broth. A simple green salad with lemon vinaigrette balances the meal. For a festive touch, serve in wide bowls with a crab cracker and an extra bowl for shells. A glass of the same white wine used in the stew pairs beautifully.
Variations
- Spicy Cioppino: Add 1–2 chopped fresh chilies (like serrano or jalapeño) with the garlic, or increase the red pepper flakes to 1 teaspoon.
- Tomato-less version: For a lighter broth, skip the crushed tomatoes and use 4 cups (960 ml) of seafood stock, plus a splash of white wine and a pinch of saffron.
- Add sausage: Brown 1/2 pound (225 g) of Italian sausage (casings removed) before the onions for a heartier, meatier stew.
- Use frozen seafood: Frozen shrimp, clams, and fish work well—just thaw them in the refrigerator overnight and pat dry before adding.
Storage and Reheating
Refrigerate leftovers in an airtight container within 2 hours of cooking. The stew will keep for up to 3 days. To reheat, warm gently in a pot over medium-low heat, adding a splash of water or stock if it’s too thick. Avoid boiling, as the seafood can become rubbery. For best texture, remove the seafood pieces before reheating the broth, then add them back in just to warm through. Freezing is possible for up to 2 months, but the texture of the shellfish may suffer; thaw overnight in the fridge and reheat gently.
Frequently Asked Questions
What is the best fish for cioppino? Use firm, white, mild fish like cod, halibut, sea bass, or snapper. They hold up well in the broth without falling apart. Avoid oily fish like salmon or mackerel, which can overpower the delicate flavors.
Can I use frozen seafood? Yes, frozen seafood is a convenient and often more affordable option. Thaw it in the refrigerator overnight, pat dry with paper towels, and add it as directed. Frozen clams and mussels should be thawed and then cooked until they open; discard any that don’t.
How do I clean and debeard mussels? Scrub the shells under cold running water to remove sand. To debeard, grab the fibrous
