Key Ingredients

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

• Cod Fillets: Choose thick, wild-caught portions for the best results. This mild white fish provides a wonderfully tender texture while soaking up all surrounding juices.
• Cherry Tomatoes: These add beautiful color and sweet, jammy moisture. As they bake, they burst open to create a rustic, natural pan sauce.
• Kalamata and Green Olives: I highly recommend using a mix of both varieties. They inject an incredible, briny pop of saltiness that defines the classic Mediterranean flavor.
• Red Onion: Slice them thinly to ensure they soften nicely in the oven. They provide a beautiful purple hue along with a subtle, sweet crunch.
• Olive Oil: Always select high-quality extra virgin varieties. This healthy fat coats the fish beautifully and keeps the low-carb macros perfectly balanced.
• Garlic and Herbs: Fresh minced cloves and oregano provide a deeply aromatic backbone. They elevate the entire flavor profile without adding unnecessary carbohydrates.

How to make this Mediterranean Baked Cod

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Step 1- Pat the cod fillets completely dry using a clean paper towel.

Step 2- Arrange the fish in a large baking dish and season generously with salt, pepper, and dried oregano.

Step 3- Scatter the cherry tomatoes, sliced olives, thin red onions, and minced garlic evenly over the fillets.

Step 4- Drizzle extra virgin olive oil and fresh lemon juice over the entire mixture.

Step 5- Bake at 400°F for 15 minutes until the fish flakes easily with a fork.

Common Mistakes to Avoid

• Overcooking the seafood: Leaving the fish in the oven for too long will make the texture dry and rubbery.
• Skipping the paper towel: Forgetting to pat the fillets dry will introduce excess moisture and make the sauce watery.
• Using low-quality oil: Choosing a cheap, refined oil will rob the dish of its signature, rich Mediterranean depth.

Required Equipment

• Ceramic baking dish: Distributes heat evenly to ensure your fish cooks perfectly through the center.
• Sharp chef's knife: Allows you to slice the red onions and olives swiftly and safely.
• Citrus squeezer: Extracts maximum juice from the fresh lemons while easily catching unwanted seeds.

Caleb’s Recipe Tips

If your cod fillets vary in thickness, please try to place the thinner tail pieces toward the center of your dish. This simple arrangement ensures that everything cooks at the exact same rate. Trust me, I have learned this the hard way after burning many thin edges! Also, do not hesitate to toss a few capers into the mix if you happen to love an extra punch of salty, briny flavor.

Storage Instructions

First, let your leftover fish cool completely down to room temperature before moving it. Afterward, transfer the remnants into a shallow, airtight glass container to preserve the clean flavor profile. You can safely keep it in the refrigerator for up to two days. However, I strongly advise against freezing this cooked dish because freezing completely ruins the delicate texture of the vegetables.
