Garlic Parmesan Baked Cod
There are nights when I want to cook something that feels a little special without turning the kitchen upside down.
This baked cod is exactly the recipe I reach for.
It looks like something you’d order at a nice seafood restaurant, but it comes together with a handful of simple ingredients and hardly any effort.
The best part is what happens in the oven. The butter melts with the garlic and coats every piece of fish, while the Parmesan slowly turns golden on top.
By the time it’s done, there’s a rich buttery sauce sitting in the bottom of the baking dish that’s too good to leave behind.
I always end up spooning it over the fish one last time before serving.
The cod itself stays tender enough to flake apart with a fork. Every bite has buttery garlic, little pockets of melted Parmesan, plenty of chopped parsley, and just enough black pepper to balance everything out.
If you’re serving it with mashed potatoes, rice, or even a loaf of crusty bread, make sure nothing goes to waste because that sauce deserves to be eaten too.
This is the kind of dinner that’s easy enough for a Tuesday night but nice enough to serve when people come over.
Nobody ever guesses how little work actually went into it.

How to Make Garlic Parmesan Baked Cod
Get everything ready
Preheat your oven to 400°F (200°C).
Lightly butter or spray an oval or rectangular baking dish. You don’t need anything fancy, just something that holds the fillets snugly. Keeping them close together helps the butter pool around the fish instead of spreading too thin.
Pat each cod fillet dry with paper towels. It only takes a minute, but it makes a noticeable difference. The butter and Parmesan stick better, and the fish bakes instead of steaming.
Season both sides lightly with salt and plenty of freshly cracked black pepper.
Arrange the fillets in a single layer.
Make the garlic butter
Melt the butter in a small saucepan over medium-low heat.
Add the minced garlic and stir constantly for about a minute. You aren’t trying to brown it. Once it smells fragrant, it’s ready.
Stir in the Italian seasoning, paprika and onion powder.
Take the pan off the heat and mix in the lemon juice.
Pour almost all of the garlic butter over the cod, making sure each fillet gets coated. Some of the butter will run underneath the fish, and that’s exactly what you want.
Add the Parmesan
Scatter the freshly grated Parmesan evenly over each piece of cod.
Don’t worry if some cheese falls into the butter around the edges. As it bakes, it melts into the sauce and gives it even more flavor.
Bake
Place the baking dish into the oven and bake for 12 to 15 minutes, depending on how thick your fillets are.
The fish is done when it flakes easily with a fork and looks opaque all the way through.
If you’d like those lightly browned spots across the Parmesan like you see in the photos, switch the oven to broil for the last minute or two. Stay close because Parmesan can go from perfectly golden to burnt surprisingly fast.
Finish the dish
As soon as the cod comes out of the oven, spoon some of the buttery garlic sauce from the bottom of the dish back over the top of each fillet.
Finish with a generous sprinkle of chopped fresh parsley.
You’ll notice the butter has mixed with the melted Parmesan and garlic to create a rich sauce surrounding the fish. That’s one of the best parts of the whole recipe.
Serve immediately while everything is hot.
A Few Tips That Make a Difference
Freshly grate your Parmesan if you can. It melts much better than the pre-shredded kind, which often contains anti-caking agents.
Try not to overcook the cod. Fish continues cooking for a couple of minutes after it leaves the oven, so it’s better to pull it slightly early than a minute too late.
If one fillet is much thinner than the others, check it first. You can always remove it and let the thicker pieces finish cooking.
Don’t throw away the sauce left in the baking dish. Spoon it over mashed potatoes, rice or vegetables. It’s full of garlic, butter and melted Parmesan.
What to Serve With Garlic Parmesan Baked Cod
Because the fish is rich and buttery, simple sides work best.
Creamy mashed potatoes are probably my favorite because they soak up every bit of the garlic butter sauce.
It also goes well with:
- Buttered rice
- Roasted asparagus
- Steamed green beans
- Roasted broccoli
- Garlic bread
- Simple garden salad
- Lemon roasted potatoes
Storage
Leftovers keep well in an airtight container in the refrigerator for up to 3 days.
Keep the remaining sauce with the fish rather than storing it separately. It helps prevent the cod from drying out.
Reheating
Warm the cod gently in a 325°F oven for about 10 minutes.
Spoon the garlic butter over the fish before reheating so it stays moist.
The microwave works too, but use short bursts at 50% power. Cod is delicate, and overheating it can make it dry.
Frequently Asked Questions
Can I use frozen cod?
Yes, but thaw it completely first and pat it dry with paper towels. Too much moisture will water down the garlic butter sauce.
How do I know when cod is finished cooking?
The fish should separate easily into flakes with a fork while still looking moist. If you have an instant-read thermometer, the thickest part should register 145°F (63°C).
Can I use another type of fish?
Absolutely. Haddock, halibut and pollock all work well with the same garlic butter and Parmesan topping. Just adjust the baking time depending on the thickness.
Why did my fish turn watery?
Cod naturally releases some moisture as it cooks, but drying the fillets well beforehand helps. Using a baking dish that’s too large can also make the sauce seem thinner because it spreads out more.
Can I make this ahead?
You can prepare the garlic butter several hours ahead and keep it in the refrigerator. Assemble everything just before baking for the best texture.
Can I add more cheese?
Definitely. If you love a cheesier topping, increase the Parmesan to 1 cup. It creates an even thicker golden crust while still allowing the buttery garlic sauce to shine underneath.
