Pro Tips for Amazing Baked Cod
Here you’ll find some pro tips to help you make the most amazing baked cod with veggies possible.
- Easily swap out or add more veggies. This dish is super versatile, so swap in the veggies you love most. Cherry tomatoes, asparagus, broccoli, and zucchini all work great if you need some inspiration.
- Chop all veggies into similar-sized pieces. To promote even cooking and yield the best possible texture, chop all the veggies into similar-sized pieces.
- Use your favorite boneless white fish. If cod fillets aren’t your protein of choice or you just have another boneless white fish on hand, use it! It will work just as great. Mahi mahi and halibut are both great options.

What Goes Well With Baked Cod
The juices that develop while the cod is baking are wonderful spooned over steamed white rice. If you want to go a bit healthier, opt for quinoa or buckwheat or a simple side salad. If you decide to chill this dish and eat it cold, serve it as a spread over a piece of buttery sourdough or your favorite crackers. Yum!

FAQ
How can you tell if baked cod is done?
Baked cod is done with the fish turns opaque in color and easily flakes with a fork. If you still can’t tell, check that the internal temperature has reached 145°F.
What other spices can you add to baked cod?
If you’d like to elevate the baked cod with additional spices, use some cajun seasoning, onion powder, or garlic powder in addition to the salt and pepper. If you’re into herbs, add some fresh parsley or basil to the mix. Additionally, a spritz of lemon juice is always a welcome addition to cod.
Can you use a different sauce for this recipe?
If you don’t have roasted garlic pasta sauce, use any other red sauce you can get your hands on. Stay away from creamy or cheesy sauces, as the citrus from the tomatoes is really what makes this dish so good.
Why did my baked cod turn out so tough?
Your cod likely turned out too tough if you over-baked it. White fish can be extremely finicky, so make sure to keep a close eye on it and remove it once it’s flakey.
Should you bake the cod uncovered?
To protect the cod from turning rubbery, bake it covered with aluminum foil. This will also create a subtle steaming effect and make your cod super moist.

Hi there- I'm so glad this recipe brought back fond memories for you. Thanks for commenting!
Hi! Where did you purchase the cod? ?
I dont have a specific place. I use to get it at Costco, lately Trader Joes.
Also do you bake it uncovered?
I covered it while it was baking.
Any brand pasta sauce will work? I'm gathering my ingredients to make this I LOVE dishes like these!!
Yes, you can make it with any past sauce. I would stay away from cheesy sauce.
Hi Natalya! From my understanding, you sautéed the vegetables all separately, right? Is there a reason for that?
I usually do them all separate because they have more of the golden color much quicker.
