Baked Fish with Lemon Garlic Butter
This baked fish is our absolute favorite baked white fish recipe. It's cooked in a delicious lemon garlic butter sauce until tender and flaky. It's a 20 minute dinner recipe you don't want to miss!
This baked fish recipe is delicious served with some mashed potatoes (or low-carb cauliflower rice!) and some roasted broccoli on the side.

This is a recipe for making baked white fish. There are several kinds you can choose from: cod, lingcod, grouper, snapper, tilapia. White fish are mild-flavored so it's a good choice if you're unsure about eating fish.
Bonus that they tend to be very inexpensive!
We love this recipe as it is full of bright lemon flavor that goes so well with the mild-tasting fish.
If you love lemon fish, also try our lemon pepper fish!

How to bake fish
This is a very easy recipe. Here's what you're going to do:
- Lay some lemon slices in a baking dish.
- Season the fish with salt and pepper and put it on top of the lemons.
- Melt some butter and add garlic and lemon zest to it before spooning or brushing it onto the fish.
- Now pop the fish into the oven for 10 minutes and dinner will be ready!

How long to bake fish?
One of the great things about making baked fish is that it cooks quickly so you can get a healthy dinner on the table fast.
The exact cooking time varies a little, depending on the thickness of the fish fillets. In a 425 degree Fahrenheit oven the fish will be cooked in 10-12 minutes.
Because white fish is pretty thin, it can be a little tricky to use an instant-read meat thermometer. If you want to try, fish is fully cooked when it reaches an internal temperature of 140 degrees.
How can I tell when the fish is finished cooking
When cooked, the fish will become completely opaque – rather than the slightly translucent color it has when raw. And it will flake easily with a fork.

Seasonings for oven baked fish
Lemon is a classic flavor with baked white fish. In this recipe, we add some garlic to the mix. But other flavors work well, too. To switch it up, try sprinkling on 1 teaspoon of any of the spices below when you season the fish with salt and pepper. Keep the rest of the recipe the same!
- Italian seasoning
- Dill
- Thyme
- Rosemary
- Basil
- Smoked paprika
What is the best kind of fish to bake
This recipe works best with a mild-flavored white fish. Some of our favorite kinds of white fish are:
- Cod
- Lingcod (pictured)
- Tilapia
- Haddock
- Grouper
- Rockfish
- Sole
Does the fish need to be flipped part way through baking?
Nope! White fish is very delicate and would fall apart if you tried to flip it. Simply leave it to bake on one side.

Truly restaurant style! Amazingly quick to make too. I made this recipe using fresh caught Florida Grouper (never frozen). Follow the recipe, as Ms. Stevens has written it, and you will look like a pro!
Brilliant recipe, easy and quick, so delicious
Does this need parchment paper or foil above the fish to cook?
No we bake this fish uncovered.
So easy, delicious, and elegant looking!
Outstanding!!!!!! Quick and Easy!!!!! Even a meat and potatoes man will enjoy this. Served the fish over wild rice and added tumeric to the Italian herbs.
This recipe is SUPERB!! SOOOOO delicious, ty for sharing it. My sides were pierogi casserole and cream peas!!! š¤¤š¤¤
Yummy
Super easy and super delicious! I made it with Lake Michigan Whitefish. YUM! I added dill because I didn’t have parsley š My fish had to cook about 10 minutes longer but it was a little thick. Thanks so much! I’ll be making this again!
Just made this with fresh Lake Michigan whitefish. Superb! Accompanied by dill potatoes, & fresh local corn & beets.
Thanks for this tasty & easy entree!
I love this recipe! I have tried it with Haddock, Cod and Pollock all were delicious! Thank youš
My dish came out perfect. Thanks. The garlic and lemon made it all delightful.
How much fish do I need for 45 heads?
A lot! Count on 8 ounces of raw fish per person – which will give you 6 ounces of cooked fish per serving.
Absolutely delicious! Juicy fish, not dry. The next time I will use a little less pepper.Ā
I used Tilapia fillets and they were delicious! Sides were flavored wild rice and salad. I will definitely make again. Thank you! Elaine
Easy delicious dinner. Family loved the fish and the baking time was very short. Will be using this recipe again.
Thank you for the help, my dish turned out delicious!
I made this recipe weeks ago and will be preparing it again, this evening .
I do like this recipe a lot.
Thank you.0
Hi. Was wondering if you could substitute olive oil for the butter and if so how much?
Thanks
Yes! You can use 4 tablespoons of olive oil instead. š
Tried this recipe with Northern Pike and it turned out fabulously. Did require a longer baking time as the fillets were quite thick. Will now be using this recipe on a regular basis. Thank you!
It’s great. Thank you š
This was fantastic and so quick and easy to make. Ā Thank you for sharing!!
Are you supposed to eat the lemons?
The lemons are there to flavor the fish. I squeeze their juices over top sometimes, but I wouldn’t want to eat them.
How did you get that singe on yours. Did you use those small torch, put it on broil for a minute, cook on the top rack?
A 2-minute broil at the end. It’s not in the recipe as we felt it was too much of a risk that the fish would overcook. š
Good deal with fresh Lake Huron whitefish
Best Ever!
Great Recipe for Fish!
I have made it so many times & the family just Love it!
I too have made this about 5 times, so good and easy to fix. In fact have it ready to go in the oven right now. Thank you for the recipe.
Wow! Most tender, flaky fish dish ever!!! It was a huge hit. I used tilapia and put lemon slices both under and over the fillets. We are allergic to garlic, so I added the parsley to the butter before I basted the fish. Excellent!!
I tried this recipe with halibut and it worked great. So thank you for that! I also tried it with salmon, which I know is not a white fish, but thought it was worth a shot. It wasn’t quite as good because the fillet was thicker and had to be watched more carefully in the oven. Also, it needed more heat. But all in all, this recipe is a keeper, and it’s even opening my mind to eating more fish.
I tried this recipe with halibut. It worked great … thank you. š
Would this work with salmon?
I think it would work well with salmon.
Hi Kristen, I came across your recipe this evening and had nothing laid out to cook. As O went through my freezer I found a pack of tilapia. So When I found your recipe, I wondered if it would be ok to use it on frozen fish. I tried it and my son loved it. Thanks for your recipe. I’ve never baked fish before and it turned out great. I will look for more of your recipes.
This was a quick & easy recipe! I used catfish and the flavor was amazing ! Ā I used the extra seasoning a like suggested !! Thank you very much šĀ
Wow! Thank you for the recipe.
yummy & simple
Could I make this with hake?
Yes, that would work well!
My family loved this recipe and gave it 5 stars. We will definitely use this recipe again. It is really delicious and a crowd pleaser. It was super easy to make which is great. Thank you for sharing it.
This was a really easy recipe. Even my fish hating son liked it. I love fish. Fish was a staple in my home growing up.
So quick and easy to make. Came out delicious! My kids loved it! I’ll be making this again.
This looks quick and easy. Most importantly, I think my son will actually eat it. He is not a fish lover. Fish was a staple when I grew up. We lived very close the Baltic Sea and a fish monger would come around once a week with fresh caught fish. The grocery stores of course had fish as well.
Cant’ believe how easy it was!
This was a great recipe. Thanks for sharing it!
Delicious with just lemon and salt and pepper and garlic. I served with steamed rice and fresh microwaved buttered carrots. It was a fast and delicious recipe for cod fish.
Wonderful recipe, I used Pollock filets, Italian dressing and added capers.
Thank you !
Super easy way to prepare haddock! Came out delicious. Served over farro with roasted asparagus, and drizzled some of the leftover butter sauce over the top. Yum!
I made this Baked Fish recipe using Cod and followed the recipe except I add a sprinkle of Italian Spice mix and toasted sliced almonds. My family loved it!Ā
Thank you so much for this recipe and the many others I have tried and enjoyed.
