This Parmesan Baked Cod Recipe is so popular! It's even loved by toddlers and people who don't like fish! It's the best cod, and it's keto, low carb and gluten free!

Several years ago, if anyone would've told me I'd be head over heels for a cod recipe, my response would've been, "What you talkin' 'bout, Willis?"
But this Parmesan Baked Cod with garlic butter blew me away and became an instant family favorite. And, it quickly became the most popular recipe on Cooking with Mamma C, garnering fans from around the world.
Allow me to explain. I once tried baccalà (that's Italian for dried, salted cod) and decided I didn't care for it. (But I recently made fried baccalà and loved it!)

I was completely unaware that baccalà had an alter ego - the moist, mild-tasting, sturdy, so-good-it-could-pass-for-a-poor-man's-lobster fresh cod.
So, I didn't eat cod for two whole decades.
What?!!

Yes, folks, I missed out on what has now become my favorite variety of fish. I'm so glad I eventually let a fish clerk talk me into making cod back in 2014.
That's when I took my beloved Parmesan Chicken Drumsticks with Garlic Butter recipe and turned it into a baked cod dish. A gluten-free, low-carb, keto-friendly cod recipe that even picky eaters love. It's perfect for Lent or any night of the week!
Ingredients

The coating for the fish consists of freshly grated Parmesan cheese, lemon zest, paprika, parsley and garlic powder. The other key ingredients are butter and lemon. And don't forget the cod!

How to make Parmesan Baked Cod
See the card at the end of this post for the full recipe, but here's an overview.

- Mix freshly grated Parmesan with garlic powder and paprika.
- Add lemon zest and chopped parsley to the mixture. I use this zester (affiliate link).
- Dip the cod in melted butter, then dredge it in the cheese mixture, pressing it onto the fish.
- Drizzle any extra butter over the fish.
- Bake the cod at 400 degrees F for 15 minutes.
- Squeeze lemon juice over the baked cod.
The Parmesan-crusted cod comes out of the oven in a nice pool of garlic butter begging for bread to be dipped in it. If carbs and gluten aren't issues for you, go for it!

Frequently asked questions
Now, since there are so many comments on this post, I'll share my answers to some of the most common questions about this cod recipe.
Can I prep this in advance for company?
Sure! Earlier on the day you want to serve it, dip the cod fish in the melted butter and coat it with the Parmesan mixture. Then, refrigerate it in a single layer, covered lightly with foil instead of plastic wrap, which would stick to the coating.
Remove the pan(s) of fish from the fridge 15 minutes before the cod needs to go in the oven. You might need to bake the cod slightly longer than 15 minutes if your pans are chilled, so just cut into one of the thicker pieces to see if it's ready.

Can I use frozen cod?
For best results, use fresh cod, but you can use frozen if you thaw it first. Make sure to pat the fish dry with paper towels.
Can I use fresh garlic?
Yes, several readers have substituted a chopped garlic clove for the garlic powder with great results.
What can I substitute for fresh parsley?
Try a teaspoon of dried parsley or dried basil.
Can I use bottled lemon juice?
Yes, use what you have. Next time, you can try it with the lemon zest and fresh lemon juice.
What if I don't have paprika?
Skip the paprika and then, after the fish is cooked, see if it needs extra black pepper or even a bit of red pepper.
Can I make this with haddock?
Yes. Haddock can be used as a substitute for cod.
Would this work with shrimp?
Shrimp tastes delicious with these ingredients. Here is the recipe for Baked Parmesan Shrimp with Garlic Butter.

What to serve with it
Keto-friendly options include lemon broccoli, steamed asparagus or this carrot salad. Gluten-free sides with more carbs include rice or Amish Brown Butter Mashed Potatoes.
And if none of that matters, don't forget the bread!

Parmesan Baked Cod Recipe (Keto, Low Carb, GF)
Video
Ingredients
- ¾ cup freshly grated Parmesan cheese
- ½ lemon (zest, plus juice)
- 2 tablespoons fresh parsley (cut small or chopped)
- ½ teaspoon garlic powder
- 1 ¼ teaspoon paprika
- 3 tablespoons salted butter* (See notes. Use up to 5 tablespoons if you want extra butter sauce)
- 1 ½ pounds fresh cod
Instructions
- Preheat the oven to 400 degrees F. Grease a rimmed baking sheet with cooking spray. Place the grated Parmesan on a dinner plate and add the garlic powder and paprika.
- Wash the lemon and pat it dry. Cut it in half and make zest from one of the halves by using a zester or grater to shave off the yellow part of the skin, adding it to the cheese mixture.
- Rinse the parsley and pat it dry. Cut it with scissors or chop it before adding it to the cheese mixture. Toss the cheese mixture with a fork to blend it.
- Rinse the fish in cold water and rub your thumbs along the surface to see if there are any bones to remove. Pat the fish dry with paper towels.
- Melt the butter in a small pan on the stove or microwave it in a bowl. Set up an assembly line from left to right with the fish, the butter, the cheese mixture, and the sheet pan.
- Use a fork to dip each piece of fish in the butter on both sides, then in the cheese mixture, coating both sides and patting the topping onto the cod with the fork. Place the coated fish onto the sheet pan, top with any excess melted butter and bake for 15 minutes. The cod is done when it can be easily flaked with a fork.
- Squeeze lemon juice over the fish and serve with bread for dipping in the garlic butter (you can place the pan on the table for informal dinners) or spoon the butter over rice, mashed potatoes or polenta. Store leftover cod in the refrigerator for up to three days.
Notes
- Use one garlic clove chopped or pressed instead of the garlic powder.
- Use dried parsley or dried basil instead of fresh parsley.
- Use bottled lemon juice if you don't have fresh.
- Use haddock or another thick white fish instead of cod.
- If you don't have paprika, add a little black pepper after the fish is cooked.
- If you don't have fresh cod, you can use frozen. Just make sure it's thawed completely and patted dry first.

Dianne Cummings says
My husband and I thought this was very good. Will make again!
Mamma C says
Hi Dianne - I'm glad you enjoyed this cod recipe! Thanks for letting me know.
Andre says
I tried this tonight and the flavor was great!! I did find it a bit greasy though. I will use egg whites next time to see if that helps.
Mamma C says
Hi Andre - I'm glad you enjoyed the flavor. You could try using less butter next time.
Nancy Lee says
This was great! I’ve added it to our regular meal plan. Loved that it cooks at the same temp and for the same length of time as my cornbread. I use unsalted butter, and hubby adds way too much salt. So it was perfect!!
Mamma C says
Hi Nancy - I'm glad this cod worked so well for you! I love it when I can bake two things at once in the oven.
Kathy Ramuchak says
So easy and quick to make ! I loved it. Made a couple slight changes. I put sliced almonds on top and put the fish on top of cooked spinach. 😋
Mamma C says
Hi Kathy - I love the idea of adding sliced almonds and spinach!
Cori says
Very tasty!
Mamma C says
Hi Cori - I'm glad you enjoyed this cod recipe!
Sandi says
Excellent!!!! I didn’t have garlic powder so I used fresh and minced it very fine. I also didn’t have parmigiana I use pecorino Romano cheese. I also didn’t have lemon so I omitted it.
Although I didn’t follow the recipe it was still awesome. I will definitely make this again. Next time I’ll make sure I have all of the ingredients.
Mamma C says
Hi Sandi - I'm so glad you enjoyed this!
Katherine Horton says
I made this over the weekend and it was the best cod I have ever eaten. I did add a touch of cayenne just because!! Thank you for a wonderful easy delicious meal. Served with rice pilaf and fresh asparagus, heaven!!
Mamma C says
Hi Katherine - I love hearing that! Your side dishes sound excellent with it too.
Melanie Swarthout says
Very good. Both my husband and I love this dish. We have it weekly.
Mamma C says
Hi Melanie - That's great to hear! Thanks so much for letting me know.
Suzanne says
VERY BLAND!! No salt was in the recipe .. should have had real garlic in the butter. Sorry but just wasn't good at all!
Mamma C says
Hi Suzanne - It sounds like you used unsalted butter. I use salted butter and find it's plenty salty with the Parmesan. I added a note to the recipe to add salt if using unsalted butter. As with any recipe, you can add salt to your liking.
Mary B says
Made this tonight for my family. I used COSTCO cod, so I doubled the parm and seasonings because I had so much fish. This recipe was delicious and best yet I didn't have to make two separate dishes because I'm on the Keto diet. Printed this recipe as a keeper to make often.
Mamma C says
Hi Mary - I'm glad this cod recipe worked so well for you! It's perfect for anyone doing keto. Enjoy.
