Perfect for when you need a quick meal: Made in one dish with tomatoes, olives and onions, this Mediterranean Baked Cod is an easy and healthy weeknight dinner!
Baking fish makes prep so simple, and adding olive oil, tomatoes, olives and garlic to the baking dish infuses the fish with so much flavor!
Does fish intimidate you? Because confession: It definitely intimidates me. Which is why, honestly? 99% of the time, I bake my fish. For proof, see my Garlic Butter Lemon Baked Cod, or my Crispy Oven Fried Fish!
It’s easy, it creates a sauce as it bakes and it’s as hands-off as it will get with fish. Although I have recently discovered the ease and deliciousness of Air Fryer Salmon… But that’s almost like baking, so there you go. Baked fish is the best ?
I first shared this mediterranean-inspired cod recipe a few years ago, but thought it deserved new photos. So here it is again, all new and shiny!
This recipe for baked cod

Ingredients you’ll need
Here is a visual overview of the ingredients in the recipe. Scroll down to the printable recipe card at the bottom of this post for quantities!
Ingredient notes
- Cod: This recipe is delicious with any white fish that bakes in 15-20 minutes. Choose thicker, firmer fish fillets for best results.
- Tomatoes: Feel free to use regular tomatoes vs cherry tomatoes. I recommend removing at least part of the seedy part to keep the dish from turning out watery. Dice the tomatoes into 1-inch pieces before adding to the dish.
- Red onion: Feel free to leave these out if you’re sensitive to onion.
- Olives: If you don’t like olives, leave them out. Capers are a great substitute, if you like those. Green olives can also be used, but I personally prefer black ones (Kalamata are my favorite!).
- Butter: The butter is technically not needed, but it does yield a super delicious sauce and helps to keep the fish from drying out. Feel free to cut the amount in half or leave it out entirely for a slimmer dish. If you leave it out, brush the top of the fish with olive oil.
- White wine: This recipe is delicious with white wine, but works great with just water, too. So don’t worry if you don’t want to use the wine, it’s not essential to the success of the recipe.

- If you have skin-on fillets, place the fish with the skin down to reduce the risk of sticking.
Recipe FAQs
How long to bake cod
The exact baking time depends on the thickness of your fish pieces. Around 20 minutes is what mine usually need.
It’s best to check the temperature with a kitchen thermometer (FYI, this is an affiliate link and I’ll make a commission for purchases made after clicking through).
What temperature should cod be cooked to?
I cook the fish until it reaches an internal temperature of 145°F (check with a kitchen thermometer (FYI, this is an affiliate link and I’ll make a commission for purchases made after clicking through) in the thickest part of the fish).
Another tell-tale sign your fish is done is opaque flesh that flakes easily.

Serving ideas
We love serving the baked cod with rice. It’s also delicious with a big leafy green salad and a chunk of my super easy Homemade French Bread on the side to mop up all of that sauce!
If you want to keep your meal low carb/keto friendly, try the fish over cauliflower rice!

MY HOUSE SKELLS AMAZING, THE FISH AND VEGETABLES CAME OUT WONDERFULLY. TOTAL SUCCESS. THANK YOU!!

Made this tonight, it was wonderful with no changes. Served with cauliflower rice and roasted asparagus, a perfect meal. Super easy and with only one dish used, makes for easy clean up, too.
Karen says
Easy and tasty recipe!
Kelly in Utah says
Delicious. Easy to prepare. I add a few capers for a tangy taste. I like it better with butter. Use an aluminum pan for easy cleanup
Sherry says
Not only is this recipie easy, it’s also absolutely delicious!
Nora says
I’m so glad, Sherry!
Grace pietruszka says
Excellent easy healthy recipe will make again for sure
Janice says
Made this today. Used haddock and added a bed of spinach in the baking dish. Absolutely delicious.
Elle says
Very good and easy! I did use EVOO instead of butter and juice of one lemon instead of the wine. Lovely!
Nora says
I’m so glad, Elle!
Lynn B says
We made this recipe just as you posted it. It was so easy, and truly delicious. My husband took one bite and said “we can have this again”.
Nora says
Now that is a compliment, Lynn! I’m so glad you and your husband enjoyed the cod!
Ron says
Enjoyed the recipe, especially for its simplicity and great flavour.
I added raisins and the juice of half of a lemon and it really was delicious. The raisins contrasted nicely with the capers .
Thanks for sharing.
Nora says
I’m so glad, Ron!
Nim says
I made this dish tonight, and it came out absolutely amazing. I did throw the veg in the oven 10 mins before adding the cod and garlic, which to my surprise gave a lot of natural water. So when I added the cod I didn’t add much water at all. It was so nice. I used a baguette to mop up the sauce from the casserole dish. I served the fish itself on a buttered Mediterranean rice! Mind blown! Thank you for this recipe.
Nora says
I’m so glad, Nim! And your serving suggestions sound spot on.
Carrie says
Hi Nim, I love to sauté my veg, garlic and peppers just a tad to marinate the flavors and you really should not have much water if you do the sauté or oven unless you are using a lot of tomato’s. I typically get rid of the insides of the tomato as it is not really needed but that’s personal preference and of course dietary need preference. You want to keep the veg crisp so it does not get over cooked when you place it all in the oven. I am currently making the dish and I am sure it will be devine. I will update this once we have indulged and I get a few moments. I think this recipe is spot on and thankful that Nora is sharing it with us:) Happy Eating Everyone!
Michelle says
This was very easy to make and tasted ok. There was a lot of liquid in the pan when it was finished cooking. If I make again, I might leave the wine out.
Nora says
Michelle, the liquid in the pan is kind of my favorite part of the recipe, it’s such a delicious pan sauce to serve with rice, pasta, potatoes… My family will fight over it. It also helps a lot to keep the fish juicy. But I understand if this particular part of the recipe wasn’t to your taste, and I hope you’ll like it better without the wine.
Carol Karcher says
I just made this and it will remain my go to cod recipe for life! ABSOLUTELY DELICIOUS!
Nora says
Carol, I love your comment! It’s definitely my personal go to cod recipe for life, so I’m glad I was able to share it with you.
Welma says
Thanks for the recipe
My boss love it
Nora says
I’m so glad, Welma!
Kathryn says
After cooking this, I added it to “My Favorite”. It is so easy and relatively fast. It takes the same amount of time from start to finish as cooking some rice to go with it, about 45 minutes. I like Black rice which looks great with white fish and is low glycemic.
Nora says
I’m so glad, Kathryn! And sounds delicious with the black rice, I’m sure it looks amazing on the plate.
Kathryn Clark says
I added Feta cheese slices under the cod along with spinach which I pre-wilted in the microwave. This recipe is great without these additions, but they give it a new delicious taste.
Sarah says
Hi! Do you think I could successfully throw a can of artichokes and/or mushrooms in there? Thank you! Excited to make!!
Nora says
Sarah, I think that would be lovely!
Kathryn Clark says
I just made this recipe with a couple of small changes. I crumbled feta cheese with the vegetables and replaced the water with white wine. It was very delicious and very, very fast and easy to make! I also served it with black rice which was a nice contrast to the cod. Black rice is my favorite type of rice because it has a mild nutty flavor and has a low glycemic index. I found this on Pinterest and am putting it in my “favorite recipes”collection.
Sandra McKee says
Delicious…added capers and substituted white wine for water…yum!
Nora says
That sounds delicious!
Connie says
This recipe was absolutely delicious and so easy! Great flavor combos. I added capers just because I had them and never get to use them. Thanks for posting!
MandyG says
Delicious. The combination of the flavors was fantastic. Thank you.
Martha says
This we a great recipe that I added to my regular rotation. I added Thyme and dill. Excellent.
Paula says
I’ve made this recipe twice, once with Kale and once with spinach. It is very tasty. I had leftovers, minus the fish and I scrambled it with an egg and some feta cheese. It was amazing! I love this dish and it is so versatile. It will be
E part of my monthly menu. Thank you!
