Light, brothy fish stew with shellfish and tomatoes from southern Italy. This high protein mediterranean dish is a fresh, healthy family dinner perfect for a calorie deficit or dash diet.
Heat the olive oil in a large Dutch oven over medium heat for 1 minute until shimmering, but not smoking.
Add the onion and celery, sautéing for 3–4 minutes until translucent. Stir in the minced garlic and cook for 1 minute until fragrant.
Pour in the cherry tomatoes and cook, stirring occasionally, until softened and some juices release, about 4 minutes.
Increase heat to medium-high, add white wine, and simmer for 2 minutes to let the alcohol evaporate by half.
Add fish stock, bring to a gentle boil, then reduce to a simmer over low heat. Season with red pepper flakes, salt, and pepper.
Place white fish pieces gently in the broth and simmer uncovered for 5 minutes, making sure not to stir vigorously.
Add shrimp, calamari, and mussels. Cover and cook for 6–8 minutes until the shellfish open and seafood is just cooked through.
Sprinkle with chopped parsley and taste for seasoning. Discard any mussels that do not open.
Serve immediately in shallow bowls with extra parsley, ensuring each portion has a mix of seafood and brothy tomatoes.
