Livorno's legendary fish soup with a medley of seafood in rich tomato broth. This high protein mediterranean family feast is fresh and perfect for a special coastal-inspired dinner.
Heat 3 tbsp olive oil in a heavy-bottomed soup pot over medium heat. Add diced onion, celery, and carrot, sautéing until soft and translucent (about 8 minutes).
Add minced garlic and red pepper flakes, stirring constantly for 1 minute until fragrant; do not let garlic brown.
Pour in 0.5 cup dry white wine, raising the heat to medium-high; simmer for 2 minutes to allow the alcohol to evaporate.
Add the canned crushed tomatoes, sea salt, and black pepper. Reduce heat to low, cover, and simmer for 12 minutes to meld flavors.
Stir in fish fillets and calamari; cover and cook gently for 5 minutes. Add shrimp, clams, and mussels, nestling them into the broth. Cover and steam until the shellfish open and shrimp turn pink (about 6–8 minutes).
Taste and adjust seasoning if needed; stir in chopped fresh parsley just before serving. Discard any shellfish that do not open.
