Step 1: Prepare the Ingredients
Start by prepping all your seafood and vegetables. Chop the onion and mince the garlic. Rinse the seafood under cold water and pat dry.
Step 2: Sauté the Base
In a large pot, heat the olive oil over medium heat. Add the chopped onion and sauté for about 5 minutes until translucent. Then, add the minced garlic and red pepper flakes, cooking for another minute until fragrant.
Step 3: Build the Stew
Add the diced tomatoes to the pot, cooking for about 2-3 minutes. Then, pour in the fish stock and bring the mixture to a simmer. Season with salt and pepper.
Step 4: Add the Seafood
Once the broth is simmering, add the calamari and cook for about 5 minutes. Next, stir in the white fish and mussels (or clams). Cover and cook for another 5-7 minutes until the mussels open up and the fish is cooked through. Finally, add the shrimp and cook for an additional 3 minutes.
Step 5: Finishing Touches
Once everything is cooked, remove the pot from the heat. Stir in the lemon zest and garnish with chopped parsley.
Step 6: Let It Stand
Allow the Cacciucco to sit for about 10 minutes. This helps the flavors meld together beautifully.
Step 7: Serve
Serve the Cacciucco hot, with slices of crusty Italian bread for dipping.
