How to Make Acqua Pazza – Italian Poached Fish
Tender white fish simmered in a light tomato and white wine broth creates a fresh, rustic Italian seafood dish that tastes like the coast. Follow the step-by step photos and see the recipe card at the bottom for a printable version.
- Pat the fish completely dry. Season both sides generously with salt and pepper.
- Heat olive oil in a large skillet over medium heat. Add the fish and sear for 2-3 minutes per side until lightly golden. Remove and set aside (it will finish cooking later).
- In the same pan, add onion and fennel. Cook about 5 minutes until softened and slightly caramelized.
- Stir in garlic and red pepper flakes. Cook for about 30 seconds until fragrant. Pour in white wine and let it simmer for 2-3 minutes to reduce slightly.
- Add cherry tomatoes, water and salt. Bring to a gentle simmer and cook until they begin to burst, about 20 minutes. Return the fish to the pan. Spoon broth over the top, cover, and simmer gently for about 6-10 minutes until the fish is tender and flakes easily.
- Turn off heat. Add basil and parsley. Drizzle with a little extra olive oil. Serve immediately with crusty bread to soak up the pan juices.
Acqua Pazza FAQs
To make this recipe ahead-of-time, prep the broth 1 day ahead, add and cook the fish fresh when serving. To store, refrigerate in broth up to 2 days. You can reheat gently on low, spooning broth over fish while warming. Make sure to finish with a drizzle of olive oil to bring it back to life.
The literal translation of this Italian dish, ‘Acqua pazza’, means “crazy water” . It comes from southern Italy, where fishermen would cook freshly caught fish in simple seawater with a few tomatoes and herbs. The “crazy” part refers to how simple and improvised the broth is – just a light, flavorful liquid that lets the fresh fish shine.
Firm white fish like cod, halibut, sea bass, or snapper work best.
The fish is ready when it flakes easily with a fork and turns opaque throughout, usually after just a few minutes of simmering.
Absolutely. Shrimp, mussels, clams, or scallops all work beautifully in the flavorful tomato broth.
Serving Suggestions
This acqua pazza is best served with plenty of Italian Crusty Bread to soak up every spoonful of the light tomato and white wine broth. I love pairing it with light sides like Lemon Arugula Salad, crispy Oven Roasted Potatoes, or Roasted Fennel for a balanced meal. It also goes beautifully with Tomato Focaccia or Homemade Pasta.
My Pro Tips
Recipe Tips
- Always pat the fish dry before searing for better color
- Don’t overcook the fish – it should just flake and stay tender
- Let the tomatoes burst naturally – this builds the best flavor
- Use a good quality olive oil at the end, it makes a difference
- Keep the simmer gentle, never boil the fish
