Why You’ll Love This
As a chef and caterer, I’ve come to appreciate quick, easy meals made with simple ingredients. When they work, they are magic! And this baked cod recipe is no exception. I can’t tell you how excited I get when the simplest recipes turn out much better than the sum of their parts.
Simple ingredients with synergistic flavors—my favorite type of meal in under 30 minutes.
Baked Cod Recipe Ingredients
- Wild Cod: Or you can substitute with another type of white fish fillet, like halibut, or you could try this with salmon. Opt for wild ocean fish for the cleanest flavors and most nutrients. Look for fresh cod like, Alaskan Cod, True Cod, or Atlantic Cod- at least an inch thick. This ensures even cooking time with the tomatoes. Frozen cod fish also work, but just make sure to thaw it first and pat dry.
- Tomatoes: Fresh summer tomatoes work best here, like cherry tomatoes or grape tomatoes.
- Shallot and fresh garlic cloves: Add punchy, aromatic flavor.
- Extra virgin olive oil: Gives delicious richness to the dish, creating a fragrant sauce.
- Vinegar: Use sherry vinegar or red wine vinegar for a touch of acidity and brightness.
- Fresh lemons: To give the dish a bright, summery feel.
- Fresh basil leaves: Basil pairs perfectly with the tomatoes, basil, garlic and lemon.
- Seasoning: Salt and black pepper, optional Aleppo chili flakes or red pepper flakes.
baked cod Instructions
Preheat oven to 425F.
Step one: Pour olive oil and vinegar into a 9×13 inch baking dish. Sprinkle the shallots and garlic into the dish, then add the tomatoes, salt, pepper, and lemon slices. Toss the tomato mixture together. Roast 10 minutes, then give the pan a good shake.
Step two: Pat the fish dry and brush with a little olive oil and season with kosher salt and pepper, and Aleppo chili flakes if using.

Step three: Nestle the cod filets into the baking dish between the tomatoes. Reduce heat to 400F and bake 8-10 minutes. Give the pan another good shake, then scatter with lemon zest. Bake for 3-4 minutes more until golden brown, or until the fish is cooked through and fork tender. If you have a thermometer, the ideal internal temperature is 145F.
Step four: Remove from the oven and add the torn basil leaves. Toss them around with the tomatoes, allowing the herb to wilt. Then garnish each piece of cod with some of the basil.
Serve immediately, making sure to gather up some of the delicious juices to drizzle over top! Add a squeeze of fresh lemon juice if you’d like, or garnish with fresh herbs, like parsley.

Storage
Leftovers taste great for up to 3 days! Let cool, then store in an airtight container in the fridge.
Serving Suggestions
Serve the Baked Cod with black rice, creamy polenta, risotto, cauliflower rice, or with a side of grilled veggies, Roasted Broccoli Salad, or this Baked Zucchini with Garlicky Parmesan Breadcrumbs.

This is one of my favorite seafood recipes! I know you’ll love this one- it is surprisingly good for how easy it is. Give it a try and let me know what you think!

Can leftovers be frozen?
Hi Natalie- I haven’t tried freezing this- it should be fine- my only hesitation is fish may crumble a bit when reheated.
I have made this about 5 times now using multi-colour tomatoes and basil from the garden, and have loved it every time. It is lovely paired with Parmesan cheese and peas orzo.
Awesome Graham!
It was amazing !! I just used sliced Roma tomatoes since I didn’t have cherry tomatoes .
It was delicious !! Thank you so much for this recipe – perfect for my dinner on intermittent fasting and low carb🤗
Oh perfect Cindy!
Hello just getting the ingredients ready and you have red wine vinegar or sherry vinegar. But it doesn’t indicate when to use this in the instructions. Wait your advIce, thank you.
Oops, fixed it sorry- add with the oil.
Went to supermarket snd there was a pack of reduced Atlantic cod so Just made this I used 3 large old tomatoes chopped which I had in and dried basil which I had it was absolutely delicious my mouth is still zinging! I served it with mashed sweet potatoes. A fantastic and simple recipe! Thank you 😊
Made it for dinner last night. So easy and delicious. I used fresh herbs from my hydroponic garden….yum. Thanks for the recipe.
I absolutely love this recipe and this time I made the garlicky breaded zucchini, which are to die for!
I have made this with cod and wondered if tilapia would work too?
Yes, just watch baking time- it may cook much quicker as it is usually thinner.
How long do you let it bake and at what degree?
Scroll down to the recipe card, below the post. 🙂
Was a hit! My first time cooking fish and very impressed, so much flavour. My boyfriend even asked for this on his birthday! Thanks Sylvia 🙂
Unfortunately this dish didn’t do it for me. I followed the recipe to a tee. I felt like the Cod was fairly bland, it just tasted like whatever I seasoned it with (so basically, salt, pepper, chili flakes, and lemon). It definitely was healthy and looked beautiful, but the flavors weren’t there for me. Any suggestions? Or is cod just simply a more mild fish?
It is definitely a mild, not oily fish. Maybe it is just not for you?
Made this tonight as just what I needed to use available ingredients. It was very tasty and can be altered accordingly.
🙌 Great to hear.
What could I substitute for the tomatoes? My household isn’t a fan of tomatotes.
What about red bell pepper?
Just made this recipe and it was amazing! What is the best way to reheat the left overs?
I would just gently bake- 350F
Thank u!
easy to make, but help with European measurements,but overall very good.
Thank Nigels!
What do you think i could use instead of the lemons?
Hi Abby you could leave them out? Or lime?
So glad I found this dish makes the fish so much more enjoyable and definitely going in my folder to use again. I did sautéed potatoes and courgette to go with it, the perfect match.
Perfect!Glad it worked for you! 🙌
Very good. I’d recommend piercing the tomatoes before cooking. Since I didn’t have fresh basil, I sprinkled the cod with crab seasoning.
where does all the sodium in this recipe come from? just the salt? I think I may try mrs dash instead
I’m sorry Gary there was an error in the calculator. Fixed now. 🙂
This recipe is 10/10. It was affordable, easy to make, healthy and most importantly, delicious! Definitely a recipe to add to your repertoire!
thanks Sophia!
Made this tonight for the 1st time, PERFECT! I followed the instructions as given (maybe I added a little more garlic 😉) and the whole family loved it. Even my son who hates cooked tomatoes ate the whole thing! He said these were the only kind of cooked tomatoes he’d ever eat. Woah.. Perfectly cooked fish, light and flaky. Served over quinoa (another thing my sons not terribly fond of) and he still ate it all. Really simple but that’s what makes it great. So very delicious, 5+ stars. Thank you!!
Awesome to hear Mark – so happy your son liked this!
Substituted salmon for cod. Simple and tasty, served it at a party as a second heavier entree and it worked well.
This was so delicious and beautiful! And dead simple. I’ve made it twice so far. I even love eating the slightly roasted lemon slices. I serve it with steamed zucchini. This is going into our regular rotation!
I like eating the lemon too! Glad you liked it. 😉
Loved this! The lemon flavor was perfectly subtle and exactly right. We had it with your pesto zucchini noodles. Easy, cheap, and healthful. Thank you!
Love your pairing! great idea! Thanks!
Made this last night as I surprisingly had everything on hand. Used cherry tomatoes from my garden and frozen cod filets. Excellent! My family says “Make it again mom!”. Thanks Sylvia for a simple tasty recipe.
Im so excited to try this. I’m new to cooking fish and this looks really easy and doable. Plus cod is so affordable where I live. Do you think frozen cod is ok to use?
