Step 1: Prepare the Ingredients
Clean the Seafood: Rinse the shrimp, mussels, and squid under cold water. Ensure the mussels are scrubbed and debearded. If using whole fish, clean and cut into chunks.
Chop the Vegetables: Finely chop the onion, garlic, carrot, and celery. This mirepoix adds depth to the stew.
Step 2: Sauté the Base
Heat the Olive Oil: In a large pot or Dutch oven, heat the olive oil over medium heat.
Cook the Vegetables: Add the onion, garlic, carrot, and celery. Sauté until the vegetables are soft and fragrant, about 5-7 minutes.
Step 3: Build the Flavor
Add the Tomatoes and Wine: Stir in the crushed tomatoes and white wine. Let it simmer for about 5 minutes, allowing the alcohol to cook off and the flavors to meld.
Add Stock and Spices: Pour in the fish stock and add the red pepper flakes. Season with salt and black pepper. Bring the mixture to a gentle boil.
Step 4: Cook the Seafood
Add the Seafood: Gently add the mixed seafood to the pot. Stir to combine and reduce the heat to low. Cover and let simmer for about 10-15 minutes, or until the seafood is cooked through.
Check for Doneness: The shrimp should be pink, the mussels should be open, and the fish should flake easily with a fork.
Step 5: Serve
Taste and Adjust Seasoning: Before serving, taste the stew and adjust the seasoning as needed.
Garnish and Enjoy: Ladle the Caciucco into serving bowls, garnish with fresh parsley, and serve with crusty bread on the side for dipping.
Variations
Seafood Choices: Feel free to substitute the seafood based on your preference. Clams, scallops, or even firm tofu can be great alternatives for a vegetarian option.
Spice Level: Adjust the amount of red pepper flakes for more or less heat. For a milder flavor, omit them entirely.
Tomato Base: If you prefer a thicker stew, add a tablespoon of tomato paste along with the crushed tomatoes.
