Mediterranean Baked Cod with Tomatoes, Olives, and Lemon

This Mediterranean baked cod is a bright one-pan dinner built around flaky white fish, burst cherry tomatoes, briny olives, capers, garlic, lemon, and olive oil. The sauce comes together in the baking dish while the fish cooks, making the recipe quick enough for a weeknight but special enough for guests.

Use fresh or fully thawed cod fillets and adjust the baking time for their thickness. The fish is ready when it flakes easily and reaches a safe internal temperature, while the tomato and olive mixture becomes glossy and fragrant.

Ingredient Notes

Cod or another white fish

Choose cod, haddock, pollock, or another firm white fish fillet of similar thickness. Pat the fish dry so the seasoning adheres and the surface roasts rather than steams.

Tomatoes, olives, and capers

Cherry tomatoes release enough juice to create a light sauce. Kalamata olives add salt and fruitiness; rinse them if they are especially salty. Capers bring a sharp briny note, so add salt gradually.

Lemon and herbs

Add lemon slices before baking for aroma and finish with juice and parsley after baking. Oregano, thyme, or basil can replace the parsley or be added alongside it.

How to Make Mediterranean Baked Cod

1. Heat the oven and season the fish

Heat the oven to 220°C (425°F). Pat the cod dry and season with black pepper, oregano, and a modest amount of salt.

2. Build the tomato-olive base

Add tomatoes, olives, capers, garlic, olive oil, and chili flakes if using to a baking dish. Toss to coat, then roast for 10 minutes so the tomatoes begin to soften.

3. Add the cod

Make spaces in the tomato mixture and place the cod fillets in the dish. Top with lemon slices and drizzle with a little more olive oil.

4. Bake until flaky

Bake for 12–18 minutes, depending on the thickness of the fillets. The cod should flake easily and be opaque in the center. For a precise check, fish is generally considered done at 63°C (145°F) measured in the thickest part.

5. Finish the sauce

Spoon the tomato juices over the fish. Add lemon juice, parsley, and a final drizzle of olive oil. Serve immediately with bread or a grain.

Serving Suggestions

Serve the cod with crusty bread or spoon it over couscous, rice, or bulgur to catch the sauce. A crisp Greek horiatiki salad balances the warm fish, while air fryer tandoori vegetables add another colorful vegetable side. For a larger Mediterranean spread, add stuffed grape leaves.

Tips for Tender Fish

• Thaw frozen fish completely in the refrigerator and pat it dry.
• Choose fillets of similar thickness so they finish together.
• Roast the tomato mixture first to avoid overcooking the fish while the vegetables soften.
• Start checking the cod at 12 minutes; thin fillets finish quickly.
• Let the fish rest for 2–3 minutes before serving, but do not leave it at room temperature for extended periods.

Variations

Use salmon for a richer version, add sliced fennel for a sweet anise note, or stir in white beans for a more substantial one-pan meal. Replace capers with chopped green olives if that is what you have. A small pinch of saffron gives the tomato broth a luxurious finish.

Storage and Reheating

Refrigerate cooked fish promptly in a shallow airtight container. USDA guidance recommends using cooked fish leftovers within 3–4 days when refrigerated at 4°C (40°F) or below. Reheat gently until steaming hot, preferably in a covered pan with a spoonful of the tomato sauce to prevent drying.

Frequently Asked Questions

Can I use frozen cod?

Yes. Thaw it completely in the refrigerator, then pat it very dry before seasoning. Cooking from frozen can release excess water and change the baking time.

How do I know when cod is cooked?

The flesh should be opaque and flake easily with a fork. A thermometer inserted into the thickest part should read 63°C (145°F).

Can I prepare the tomato mixture ahead?

Yes. Chop the ingredients and refrigerate them separately or assemble the tomato base for up to one day. Add the fish shortly before baking for the best texture.

Is this recipe gluten-free?

The fish and tomato-olive base are naturally gluten-free. Serve with rice or certified gluten-free bread, and check stock or packaged seasonings if needed.
