Servings and timing

This recipe yields 4 servings. Total time required is approximately 25 minutes — 5 minutes for preparation and 20 minutes for baking.

Variations

  • Add Lemon: Place thin lemon slices over the cod before baking for added brightness.
  • Spicy Option: Add a pinch of red pepper flakes or sliced chili for a gentle kick.
  • Use Different Fish: Substitute cod with haddock, halibut, or sea bass if preferred.
  • Herb Swap: Use fresh basil or parsley instead of rosemary for a different flavor profile.
  • Vegetable Addition: Add thinly sliced zucchini or bell peppers to the tomato mixture for a more substantial dish.

storage/reheating

Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, place in a preheated 325°F (160°C) oven for 10–12 minutes or until warmed through. Avoid microwaving for too long, as it may dry out the fish. This dish is not ideal for freezing due to the delicate texture of the cod and the moisture from the vegetables.

FAQs

Can I use frozen cod fillets?

Yes, but be sure to thaw them completely and pat dry before baking to avoid excess moisture.

What type of olives are best for this recipe?

A mix of green and black olives provides a balance of flavor, but you can use whichever you prefer or have on hand.

Is cod a sustainable choice?

Look for cod that is certified sustainable by organizations like MSC (Marine Stewardship Council) for the most environmentally responsible option.

Can I make this recipe ahead of time?

It’s best enjoyed fresh, but you can prepare the tomato and olive mixture a few hours ahead and add the cod just before baking.

What should I serve with Mediterranean baked cod?

Serve with couscous, quinoa, roasted potatoes, or a fresh green salad for a complete meal.

How do I know when the cod is done?

The fish should be opaque and flake easily with a fork. An internal temperature of 145°F (63°C) indicates doneness.

Can I add capers to this recipe?

Yes, capers add an extra burst of briny flavor and pair beautifully with the olives and tomatoes.

What if I don’t have fresh herbs?

Dried herbs work perfectly well. Adjust quantities to taste, typically using half the amount of dried as you would fresh.

Is this dish dairy-free?

Yes, this recipe is naturally dairy-free and suitable for those avoiding lactose.

Can I cook this in a cast iron skillet?

Yes, a cast iron skillet works well and can go straight from oven to table for serving.

Mediterranean Baked Cod with Tomatoes & Olives is a simple yet elegant dish that celebrates the bold, clean flavors of the Mediterranean diet.
