Mediterranean baked cod is one of the lightest, most flavorful fish dishes you can make. White fish like cod takes on the flavors of its cooking environment readily — so surrounding it with cherry tomatoes, olives, capers, lemon, and good olive oil results in fish that is herbaceous, tangy, and deeply satisfying despite being genuinely lean. One pan, 30 minutes.
Ingredients
Build the Base
In a baking dish, combine cherry tomatoes, olives, capers, garlic, and half the olive oil. Toss and season. Spread in an even layer. This is the bed your fish will rest on as it bakes — it creates steam and flavored liquid that bastes the cod from below.
- Preheat oven to 400°F (200°C)
- Roast the vegetable base for 10 minutes until tomatoes start to blister
- Season cod fillets, place on top of the base
- Lay lemon rounds over each fillet, drizzle with remaining olive oil
- Return to oven for 12–15 minutes until cod flakes
- Finish with fresh herbs and a drizzle of raw olive oil
"The best olive oil is for finishing, not cooking. Add a generous pour of your best cold-pressed olive oil directly onto the cooked fish just before serving. Heat destroys its subtle flavors — raw, it transforms everything."
This preparation works beautifully with any firm white fish — halibut, haddock, sea bass, or Chilean sea bass all work. Avoid thin, delicate fillets like sole or flounder, which overcook in the time the vegetables need.
