Lemon Baked Cod in Oven

One of our favorite easy healthy dinners will always be baked fish – it is light, full of flavor, and so easy.

Baked cod is especially easy and good – cod is a lighter fish with less fat than some fishes, it flakes beautifully, and it has a mild non-fishy flavor.

Most people know cod from fish and chips – but it is fabulous baked in the oven because of it's fast cooking and flaky texture.

If you are worried about fishy flavor, cod is a great fish to choose because it has a light, buttery flavor and is generally not a “fishy” fish.

Cod's flavor is so light, it is the go-to choice for fish and chips, fish frys, and is fabulous baked.

How to bake Cod

We love to bake cod because it is fast and easy – with proper cooking temperatures and times. If you cook fish for too long, or at a wrong temperature, it can quickly overcook, resulting in a dry, flavorless fish.

These steps will help you find the right temperature to cook your fish at, every time.

Preheat your oven to 450 degrees for a thicker cod fillet, or 350 degrees for a dressed fish.
Rinse cod and pat dry with a paper towel. Make sure there is no extra liquid on the fish to help ensure it cooks properly.
Place your fish in a single layer in a well prepared pan or baking dish. We like to use olive oil or coconut oil cooking spray to prevent the fish from sticking – or a little bit of garlic butter!
Brush fish with some kind of fat or sauce (butter, olive oil, or a sauce like the tomato and caper sauce we use in our Tuscan Baked Fish) to help keep fish moist and flavorful.
Season with herbs, spices, and aromatics.
For these baked cod filets, weigh your filets and plan to bake fish at 350 degrees for 6-9 minutes for every out ounces.
Watch fish carefully as it cooks to check for opaqueness to be sure fish doesn't overcook.

Baked Cod Fish Recipe Tips for Success

Since cod is a widely available fish, you can find fresh or fresh frozen fish at almost every grocery store or fishmonger – it is one of the most popular fish in America and abroad, so it is easy to find.

How to reduce fishy smells. If you've had fishy cod, and are trying to get the best flavor, please consider some of our tips below to cut down on fishy smell and flavor:

Rinse fish with cold water. Fish can collect bacteria and get a fishy smell in your refrigerator – if your fish has a slightly fishy smell, you can rinse it with COLD water to help rinse away the smell. Pat fish dry before cooking. Do not rinse fish with hot water, as it will start to cook the fish.
Soak fish in milk. It sounds totally weird, but soaking fish in milk for 20 minutes takes away any fishy smell. Pat dry before cooking.
Use acid. Lemon juice is one of the most flavorful and fragrant ways to take away any fishy smell. We're using lemon to pull out the light, sweet flavor of baked cod – and reducing the fishy smells.

Know when cod is cooked. Cod is cooked at 145 degrees – but thankfully it is an is an easy fish to tell when it is done by sight and an easy method called the flake test without a thermometer.

Do the flake test. To do the flake test, poke your fork into the thickest part of your fish at a 45 degree angle. Gently twist your fork and pull up some fish. To tell by the look of the fish, look for how translucent or opaque the fish looks.

Tell if it's done by the look. Fish that is not done cooking will still look a little translucent, and won't flake with with light twisting. Fish that is fully cooked will be bright white and fully opaque. These methods work to tell when cod is done using any method – grilling, baking, frying, or poaching.
