What to serve with Italian stewed fish?

Classic choice is bruschetta or ciabatta to mop up the sauce. Pasta (linguine, spaghetti) or polenta also pair beautifully. For a lighter option, go with rice or roasted vegetables.

Can Italian stewed fish be made ahead and how to store it?

The tomato-vegetable sauce can be made up to 2 days in advance and refrigerated. Add the fish only right before serving — reheated fish loses its texture and becomes mushy.

How to reduce the heat in Italian stewed fish without losing flavor?

Simply omit the chilli or reduce it to a small pinch of flakes. The Italian character is preserved through the capers, basil, and lemon zest.

Why does the sauce turn watery when stewing fish and how to thicken it?

Tomatoes release a lot of liquid — keep the pan uncovered while simmering. Let the sauce bubble for 10–15 minutes over medium heat without a lid until it reaches the consistency you want.

Note from Sergei

Sergei Martynov

“The beauty of stewed fish lies in its gentle simplicity. Unlike frying or grilling, stewing treats fish with tenderness — a low, steady simmer in wine-enriched tomato sauce with cherry tomatoes that burst and release their sweet juice. I've learned the hard way that high heat is the enemy here: you want the sauce to barely bubble, just enough movement to cook the fish through without breaking it apart. A firm-fleshed fish like cod, monkfish, or halibut works best. The Italian tradition of acqua pazza taught me that the best fish dishes are often the least complicated ones.”

Add the fish to the sauce in the last 8-10 minutes of cooking — this is just enough time to cook it through without falling apart. If you add it too early, you'll end up with fish flakes in tomato soup.

Method

In a large skillet with high sides, heat the olive oil over medium heat. Add the onion and garlic and sauté until soft, about 5 minutes.
Add the bell peppers and cook for another 3-4 minutes.
Pour in the tomatoes with their juice, add the olives, capers, oregano, basil and red pepper flakes. Stir and braise over low heat for 10 minutes.
Place the fish fillets on top of the vegetables, season with salt and pepper. Cover with a lid and braise over low heat for 10-12 minutes until the fish separates easily into pieces.
Add the juice and zest of the lemon and stir gently. Serve sprinkled with fresh parsley.

FAQ

Firm, mild-flavoured varieties are ideal: cod, halibut, sea bass, or sea bream. Tilapia fillet also works well — just add it at the very end as it only needs 5–6 minutes.

The residual heat continues cooking the white fish fillets for 2-3 minutes after you remove it from the pan. I pull my stewed fish when it looks slightly underdone in the center — it finishes perfectly on the plate.
