Cod is a patient fish, and it rewards a slow braise in olive oil with onion, garlic, and tomato, absorbing the sauce without losing itself entirely. Parsley finishes the dish with freshness, pulling together what the long, gentle heat has built. It is the kind of thing Margaux's grandmother would have set on the table without explanation, knowing it needed none.

Method
Pat the cod fillets dry with a clean kitchen towel. Season lightly on both sides with sea salt and black pepper. Set aside at room temperature while you build the braise.
In a wide Dutch oven or heavy-bottomed sauté pan, warm the olive oil over medium-low heat. Add the diced yellow onion with a pinch of salt and let it sweat gently for 8–10 minutes, stirring occasionally, until softened and translucent but not browned.
Add the sliced garlic and cook for another 2 minutes until fragrant and golden at the edges.
Nestle in the anchovy fillets and stir them into the onions and garlic. Let them melt and dissolve into the oil — this is the secret depth, a true Provençal touch.
Gently nestle the seasoned cod fillets into the tomato braise, laying them flat and spacing them apart. Spoon some of the braise over the top of each fillet.
Scatter the torn basil leaves over the top. Let the dish rest for 2–3 minutes off the heat so the herbs bloom in the warmth.

Dutch OvenSafety & Storage
Cooking Temperature
Fish must reach internal temperature of 145°F (63°C) throughout. Verify thickest part of cod fillets reaches safe temperature before serving. Use calibrated food thermometer.
Cross Contamination
Raw fish products (cod and anchovies) can cross-contaminate other ingredients and surfaces. Use separate cutting boards and utensils for raw fish. Clean and sanitize all equipment after handling raw fish before using for other ingredients.
High Risk Population
Pregnant women, young children, elderly, and immunocompromised individuals are at higher risk from undercooked fish. Ensure fish is fully cooked to opaque throughout and flakes easily when tested with a fork.
Storage
Leftover cod in tomato braise must be refrigerated within 2 hours of cooking. Store in airtight containers at 40°F (4°C) or below. Consume within 2-3 days. Reheat to 165°F (74°C) until steaming hot throughout.
Handling
Cod fillets should be patted dry and kept cold until cooking. Do not leave fish at room temperature for more than 30 minutes total during preparation and seasoning. Keep fish on ice or in refrigerator until ready to cook.
Allergen Warning
Both cod and anchovies contain fish allergens. Individuals with fish allergies should avoid this dish entirely. Cross-contact between fish types is possible.
Pro Tips
Technique
The anchovies are not for fishiness, mon ami — they melt completely into the braise, leaving only a deep, savory hum that you cannot achieve any other way. Do not skip them, and do not rush this step. Let them dissolve slowly into the onions until you cannot see them anymore.
Substitution
No cod at your fishmonger? Sea bass or thick-cut hake work beautifully here. The only rule: firm, white-fleshed fish that can hold its shape in the braise without falling apart.
Reheating
This braise is even better the next day, when the tomatoes have had time to deepen. Reheat gently over low heat, spooning the sauce over the fish as it warms. A splash of water or white wine loosens it perfectly.
From the chef
There is a moment in late summer, when the tomatoes are so ripe they practically fall from the vine, and the boats come into Saint-Tropez with their fresh catch — that is when I make this dish. It is not mine alone; every grandmother along the coast has her version, a humble braise where the sea meets the garden in the enamel pot. I have simply kept faith with their way: slow, patient, generous with the olive oil, and always, always letting the tomatoes and the herbs do the talking.
