Mediterranean baked cod
August 5, 2026 · 3 min read
Cod is a mild, forgiving fish that turns a weeknight dinner into something that reads like the coast of Greece with almost no effort. Halved cherry tomatoes, kalamata olives, capers, and sliced garlic go into a bowl with olive oil and lemon, then over the fillets, and the oven does the rest. One dish, about 20 minutes, and roughly 280 calories a serving of fish, vegetables, and olive oil — three foods the MIND pattern leans on.
The tomatoes are the engine here. As they bake they collapse and release their juice, which mixes with the olive oil and lemon into a light pan sauce that keeps the lean cod moist. Don't skip patting the fillets dry first, or they steam instead of soaking that up.
Ingredients
- 4 cod fillets (about 6 oz each)
- 2 cups cherry tomatoes, halved
- 1/2 cup kalamata olives, pitted and halved
- 2 tablespoons capers, drained
- 4 garlic cloves, thinly sliced
- 3 tablespoons olive oil
- 2 tablespoons fresh lemon juice
- 1 teaspoon dried oregano
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 tablespoons fresh parsley, chopped
Steps
- Heat the oven to 400°F. In a bowl, toss the cherry tomatoes, olives, capers, sliced garlic, olive oil, lemon juice, and oregano until everything is coated.
- Pat the cod fillets dry and lay them in a baking dish. Season the tops with the salt and pepper.
- Spoon the tomato-olive mixture over and around the fillets, letting the tomatoes tuck into the gaps. Bake 18 to 20 minutes, until the cod flakes at the thickest point and the tomatoes have softened and burst.
- Scatter the chopped parsley over the top and spoon the pan juices over each fillet before serving.

Notes and swaps
Any firm white fish stands in for cod — halibut, haddock, and pollock all bake the same way, though thicker cuts may want a few extra minutes. Thin fillets cook fast, so start checking at 15 minutes and pull them the moment the flesh flakes.
No kalamatas? Any brine-cured black olive works, and a spoon of extra capers pushes the whole dish more savory. For more vegetables in the pan, add sliced zucchini or a handful of spinach in the last five minutes. A pinch of red pepper flakes with the oregano gives it a low, warm heat.
Serve it over farro, brown rice, or a slice of whole grain bread to catch the juices. Say what went in the pan and MIND Diet Companion (coming soon to the App Store) shows how the day is shaping up against the pattern — no weighing, no barcode scanning.
FAQ
Is baked cod good for the MIND diet? Yes. Fish is one of the food groups the MIND pattern asks for at least once a week, and baking it with tomatoes, olives, and olive oil brings in vegetables and the pattern's core fat in one dish.
How do I know when the cod is done? The flesh turns opaque and flakes when you press it with a fork at the thickest part. For most 6-ounce fillets that lands around 18 to 20 minutes at 400°F. Pull it as soon as it flakes, since cod dries out if it sits in the heat.
Can I use frozen cod? Yes. Thaw it fully in the fridge and pat it very dry, then bake as written. Frozen fillets hold more water, so a thorough drying keeps the pan from going watery.
What should I serve with it? Farro, brown rice, or a wedge of whole grain bread soaks up the pan juices, and a simple green salad rounds it out. See read a recipe at a glance for how the bake order fits together, and the MIND diet for where fish and olive oil sit in the wider pattern.
Can I make it ahead? The tomato-olive mixture can be tossed a day early and kept in the fridge, so dinner is just seasoning the cod and spooning it over. Bake it fresh, though — reheated fish loses the flaky texture.
