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!

Ingredients you’ll need

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.

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!

This was fantastic and soooo easy. My husband said it was the best fish dish I have ever made. I made 2 portions in individual bakers and skipped the olives in his. I forgot the butter, but I don’t think I really missed it (I did drizzle a healthy dose of olive oil over everything before baking). I was going to add some spinach toward the end of baking but forgot that also. Added chopped fresh basil before serving. I served with bread since we aren’t a huge rice family, and we soaked up every bit of the juices with it.
