Step 1: Prepare the Crostini
Preheat your oven to 400°F (200°C).
Arrange the baguette slices on a baking sheet.
Drizzle olive oil over the slices, making sure they’re lightly coated.
Toast in the oven for about 8-10 minutes, or until golden brown.
Rub the toasted bread with the halved garlic for added flavor. Set aside.
Step 2: Make the Cacciucco
In a large pot, heat the olive oil over medium heat.
Add the chopped onion, carrot, and celery. Sauté for about 5-7 minutes until the vegetables are soft.
Stir in the garlic and red pepper flakes, cooking for another minute until fragrant.
Add the diced tomatoes and cook for 3-4 minutes until they break down slightly.
Pour in the fish stock and white wine. Bring the mixture to a simmer.
Add your seafood (shrimp, mussels, clams, and fish) to the pot. Cook for about 5-7 minutes or until the seafood is cooked through and the mussels have opened.
Season with salt and pepper to taste.
Let it stand for 10 minutes to allow the flavors to meld together.
Step 3: Serve
Ladle the Cacciucco into bowls, garnishing with chopped parsley.
Serve with crostini on the side for dipping.
