Provençal Fish Stew

Why This Provençal Fish Stew Works

As the pot heats up, the onion, leeks, garlic, and fennel soften in the olive oil. They lose their bite and start to taste sweeter and milder, so the base of the stew is smooth instead of sharp. While they cook, the saffron, thyme, oregano, bay leaf, and orange zest warm up in the oil and spread through the vegetables, so that flavor is already in the liquid before any seafood goes in.

Once the tomatoes, fish stock, and wine start to simmer, the liquid thins out the tomatoes but also picks up body from them. Over several minutes, the broth becomes more unified and a little thicker, so it can cling to the fish and shrimp instead of feeling watery.

When the fish, mussels, and shrimp go in, they gently poach in that hot broth. The steady simmer cooks the seafood through without tearing it apart. Fish stays moist and flaky, shrimp stays tender, and the mussels open and loosen into the stew. Right at the end, parsley goes on fresh so it doesn’t wilt away, and the toasted baguette soaks up the broth without falling apart.

Mistakes To Avoid

Letting the fish and shrimp simmer too long turns them tough and dry. The delicate pieces start to break apart in the pot, so instead of nice chunks of fish, the stew ends up with stringy bits and rubbery shrimp floating around.

Adding the shellfish and fish before the broth is at a steady simmer often leads to uneven cooking. Some pieces sit in cooler liquid and stay slightly raw in the center while others, closer to the heat, overcook and go mushy.

Crowding the pot with whole, thick fillets can cause the outside of the fish to flake off while the center is still underdone. As people stir, those big pieces fall apart, and the stew turns cloudy and full of tiny shreds instead of clean pieces of seafood.

Throwing the mussels in without checking and discarding cracked or open ones can spoil the whole pot. A bad mussel can give off a strong off-smell and taste that spreads through the broth and makes the stew unpleasant.
