Equipment Needed

Preparation Time

  • Prep Time: 20 minutes
  • Cooking Time: 35 minutes
  • Total Time: 55 minutes
  • Servings: 4–6

Step 1: Prepare the Fish

Rinse the fish fillets under cold water and pat dry with paper towels.

Remove any remaining bones and cut the fish into bite-sized chunks. Set aside while preparing the broth.

Fresh fish is the key to achieving the best flavor and texture in this soup.

Step 2: Build the Flavor Base

Heat olive oil in a large soup pot over medium heat.

Add:

  • Onion
  • Celery
  • Carrot

Cook for 5–6 minutes until softened.

Add minced garlic and cook for another minute until fragrant.

The vegetables create a flavorful foundation that enriches the broth.

Step 3: Add Tomatoes and Seasonings

Stir in:

  • Diced tomatoes
  • Tomato paste
  • Oregano
  • Thyme
  • Bay leaf
  • Saffron (if using)

Cook for 3–4 minutes until the tomatoes begin to soften and release their juices.

This step deepens the soup's color and flavor.

Step 4: Simmer the Broth

Pour in the fish stock.

Bring the mixture to a gentle boil.

Reduce heat and simmer for 20 minutes.

As the broth cooks, the vegetables soften completely and the herbs infuse their aromas throughout the soup.

Step 5: Add the Fish

Carefully add the fish pieces to the simmering broth.

Cook for 6–8 minutes.

Avoid vigorous boiling, as delicate fish can break apart.

The fish should become opaque and flaky while remaining tender and moist.

Step 6: Finish the Soup

Remove the bay leaf.

Stir in:

  • Lemon juice
  • Fresh parsley

Taste and adjust seasoning with additional salt and pepper if needed.

The lemon brightens the flavors and balances the richness of the broth.

Step 7: Serve

Ladle the hot soup into serving bowls.

Garnish with:

  • Fresh parsley
  • Lemon wedges
  • A drizzle of olive oil

Serve immediately with warm crusty bread for dipping.
