Ingredients
Method
- Heat the oven: Preheat to 425°F (220°C). Lightly oil a 9x13-inch baking dish or similar pan.
- Prep the base: In the pan, toss tomatoes, red onion, garlic, olives, and capers with 2 tablespoons olive oil, 1 teaspoon dried oregano, a pinch of red pepper flakes, and a big pinch of salt and pepper.
- Roast the veggies: Spread evenly and roast for 10–12 minutes, just until the tomatoes start to burst and the onions soften.
- Season the fish: Pat cod dry. Rub with 1–2 tablespoons olive oil, salt, pepper, and a light sprinkle of oregano. Zest half a lemon over the fillets if you like extra brightness.
- Nestle and bake: Take the pan out. Stir in the juice of half a lemon with the vegetables. Nestle the cod fillets on top. Spoon some of the mixture and juices over each piece.
- Finish in the oven: Bake 10–14 minutes, depending on thickness. The cod is done when it flakes easily with a fork and turns opaque (internal temp about 145°F/63°C).
- Add fresh herbs and feta: Squeeze the remaining lemon over the fish. Scatter parsley (and dill, if using) and crumble feta on top. Taste and adjust salt, pepper, or lemon as needed.
- Serve: Spoon the pan juices over each plate. Serve with bread, rice, or orzo to catch the sauce.
Why This Recipe Works
- High heat, short time: Baking the cod at a fairly high temperature keeps it moist and flaky without overcooking.
- Layered Mediterranean flavors: Tomatoes, olives, capers, garlic, oregano, and lemon create a quick pan sauce that tastes long-simmered.
- One-pan convenience: The veg and aromatics cook under and around the fish, so cleanup is minimal.
- Flexible and forgiving: You can use fresh or canned tomatoes, different olives, and even swap in other white fish if needed.
- Balanced and light: Plenty of protein, heart-healthy fats from olive oil, and bright acidity make it satisfying without feeling heavy.

How to Make It
- Heat the oven: Preheat to 425°F (220°C). Lightly oil a 9×13-inch baking dish or similar pan.
- Prep the base: In the pan, toss tomatoes, red onion, garlic, olives, and capers with 2 tablespoons olive oil, 1 teaspoon dried oregano, a pinch of red pepper flakes, and a big pinch of salt and pepper.
- Roast the veggies: Spread evenly and roast for 10–12 minutes, just until the tomatoes start to burst and the onions soften.
- Season the fish: Pat cod dry.
Rub with 1–2 tablespoons olive oil, salt, pepper, and a light sprinkle of oregano. Zest half a lemon over the fillets if you like extra brightness.
- Nestle and bake: Take the pan out. Stir in the juice of half a lemon with the vegetables.
Nestle the cod fillets on top. Spoon some of the mixture and juices over each piece.
- Finish in the oven: Bake 10–14 minutes, depending on thickness. The cod is done when it flakes easily with a fork and turns opaque (internal temp about 145°F/63°C).

Scatter parsley (and dill, if using) and crumble feta on top. Taste and adjust salt, pepper, or lemon as needed.
- Serve: Spoon the pan juices over each plate. Serve with bread, rice, or orzo to catch the sauce.
How to Store
- Refrigerator: Store leftovers in an airtight container for up to 2 days.
Keep the fish separate from sides to prevent sogginess.
- Reheat gently: Warm in a 300°F (150°C) oven for 8–10 minutes, or microwave in short bursts at 50% power. Avoid overcooking.
- Freezing: Not ideal. Cooked cod can turn mushy after thawing, and tomatoes lose texture.
- Next-day ideas: Flake cold cod over a salad with the leftover tomatoes and olives, or tuck into a warm pita with yogurt sauce.
Health Benefits
- Lean protein: Cod is low in fat and high in protein, supporting muscle repair with fewer calories.
- Omega-3s: While cod has less than fatty fish, it still contributes heart-friendly omega-3 fatty acids.
- Mediterranean staples: Olive oil, tomatoes, garlic, and herbs align with a heart-healthy eating pattern linked to better long-term wellness.
- Lower sodium control: Using olives and capers provides big flavor, so you can add less salt overall.
- Antioxidants: Tomatoes, garlic, and herbs bring vitamins and protective plant compounds.
Pitfalls to Watch Out For
- Overcooking the fish: Cod goes from perfect to dry fast.
Start checking at 10 minutes.
- Watery sauce: If using canned tomatoes, drain them well. Roast the vegetables first to reduce moisture before adding the fish.
- Too salty: Olives, capers, and feta are salty. Rinse capers, pat olives dry, and season the fish lightly until the end.
- Bland flavor: Don’t skimp on lemon zest, fresh herbs, and good olive oil.
They make the dish sing.
- Crowded pan: If the pan is packed tight, the veggies steam instead of roast. Use a larger dish or two smaller ones.
Recipe Variations
- With potatoes: Par-roast thinly sliced baby potatoes with olive oil and oregano for 20 minutes, then add the tomato-olive mix and proceed with the recipe.
- Spicy harissa twist: Add 1–2 teaspoons harissa paste to the vegetables before roasting for gentle heat and depth.
- Orange and fennel: Swap red onion for sliced fennel and add a few strips of orange zest; finish with orange juice plus lemon.
- Herb-forward: Use fresh oregano and mint instead of dill. Add a handful of chopped spinach or arugula at the end to wilt in the heat.
- Different fish: Try haddock, pollock, halibut, sea bass, or tilapia.
Adjust baking time to the thickness.
- Tomato-free: Use roasted red peppers and artichoke hearts in place of tomatoes for a sweeter, milder base.
FAQ
Can I use frozen cod?
Yes. Thaw completely in the refrigerator overnight, then pat very dry. Excess moisture can water down the sauce and prevent good roasting.
What if I don’t have Kalamata olives?
Use any briny olive you like, such as Castelvetrano or green olives.
Just pit and halve them. The flavor will shift slightly, but it will still be delicious.
How do I know when the fish is cooked?
The flesh turns opaque and flakes easily with a fork. If you have a thermometer, aim for 145°F (63°C) in the thickest part.
Can I make this dairy-free?
Absolutely.
Skip the feta or use a dairy-free alternative. The dish has plenty of flavor from herbs, olives, lemon, and garlic.
What sides go well with this?
Crusty bread, lemon rice, orzo, couscous, or a simple green salad. Roasted asparagus or sautéed greens also pair nicely.
Is cod sustainable?
Look for certifications like MSC or guidance from reputable seafood guides.
Availability and sustainability vary by region and fishery.
Can I meal-prep this?
You can prep the vegetable base in advance and keep it chilled. Bake the fish fresh for the best texture, since reheated cod can dry out.
Final Thoughts
Greek-style baked cod proves that simple ingredients can deliver big flavor. With a handful of pantry staples and fresh herbs, you get a bright, satisfying meal that feels special yet fits any weeknight.
Keep the heat high, watch the timing, and finish with lemon and herbs for the best result. Serve it family-style with plenty of bread to soak up the sauce, and enjoy a little Mediterranean sunshine at your table.
