This Baked Fish recipe comes with a Lemon Cream Sauce and is made in ONE baking dish! Yup, just throw it all in one pan, bake it, and you end up with a tender juicy fish in a creamy lemon sauce. The the juices of the fish mingles in with the sauce while it’s baking, as if made from the best fish stock!
This is a reader-favourite recipe included by popular demand in my debut cookbook “Dinner”!

Baked Fish
If the idea of baked fish conjures up the words pale, colourless and bland, then this one’s going to be a game changer for you!!
It’s an effortless 15 minute recipe one pan recipe where fish is baked with a creamy lemon sauce. It’s the sort of recipe you can make no matter how hectic your household is, or on a lazy Sunday night because it’s this easy:
Mix butter, cream, garlic, mustard and lemon;
Pour over fish; and
Bake – no flipping required.
And out comes this – tender baked fish fillets with a beautiful lemon cream sauce that’s perfect with fish!
This recipe will work for most fish, but is especially great for white fish fillets

When you bake fish, you just can’t get colour on it like you can with pan frying, and this means loss of flavour. So I like to either have a flavoured crumb, like I do for my other Emergency Fish recipe, Parmesan Crusted Fish (10 minutes, no messy dredging!) or a Sauce.
The Lemon Cream Sauce for Fish
This recipe really is all about that Lemon Cream Sauce for fish which is made in the same pan while the fish is baking. It’s a simple sauce which actually tastes pretty unimpressive when you first mix it up.
But once it’s baked and the fish juices mix in with it, it transforms into an incredible sauce. It’s basically like making a sauce with real homemade fish stock – just like fine dining restaurants do!
What this tastes like
The recipe name implies that the sauce is rich but actually, it is not! I describe it as kind of light and fresh, yet a bit creamy. You will be thankful there is a decent amount of sauce because it’s perfect for mopping up with bread or spooning over mashed potato!

What you need
Not very much!
White Fish fillet – any fairly flat white fish fillet is fine here, about 2 cm/ 4/5 ” thick or less. Any thicker, and the fish will take longer to bake which will thicken the sauce too much so you’ll need to thin it with a splash of water.
Escallot/French onion – those small onions, they’re more delicate than normal onions so they work well in a quick fish recipe like this. Use the white part of green onions as a sub, or really finely minced normal onion.
Dijon Mustard – sauce thickener. Can sub with other non seedy mustards.
Garlic – goes in almost everything in my world!
Cream – use heavy / thickened cream if you can, to help with sauce consistency. Low cal sub – evaporated milk. It’s not quite the same, but I’ve been known to use it when I’m trying to be “healthier” 😂
Butter – there is no substitute! 😂
Lemon – lime would work in an emergency situation. Sub: 1/3 cup white wine simmered to reduce to 2 tbsp, use in place of lemon in recipe.

Yesterday was a day of experimenting with slow cooked curries. So there was plenty of downtime spent doing THIS!

And from when I originally published this recipe in October 2016:
From a little camping trip last weekend – getting smashed in the waves at beautiful Jimmy’s Beach, NSW Australia. He’s a sucker for punishment, that one. I really have to keep an eye on him to make sure he doesn’t get swept away by a rip!!

Dear Nagi,
By “cream” do you also mean sour cream? I have a delicious heavy sour cream in my fridge (hoping I can use it).
Thanks(:
Well this is just absolutely blimin delicious AND super easy too…yum!!! Thanks Nagi
This is the best fish dish I’ve ever made. The sauce is so incredible. My four children all loved it so much. I couldn’t find enough fresh fish at the market for our family so I used frozen. I added the sauce/ onions for the last ten minutes of cooking. For fun I made your corn bread on the side which was also so incredible. I’m so excited to make the cornbread for Thanksgiving, and I think we might have this fish every week. because it was sooooooooo good!!
Just made it for the first time and we all enjoyed it. Thanks a lot for sharing this recipe😍
Made this for the second time tonight. I forgot how delicious it was. Served with mashed potato, peas and pamesan crisps. Delicious
Oh my goodness! Made this for the first time today and it was simply delicious. Thank you so much.
Wahoo, that’s great to hear Nicki!!! N x
I just made this…and omg…its absolutely delicious…thank you…thank you…thank you
I used boring, frozen whiting fillets and the finished dish tasted like a fancy restaurant entree. Yummm! I served it with your recipe for mushroom rice recipe and steamed zucchini. Thanks for yet another brilliant recipe.
Wahoo, that’s awesome Christine!! N x
Great recipe. Made this yesterday for Sunday dinner and the family loved it! Love your videos and recipe format. Keep up the good work, Nagi.
This was fantastic and will certainly be part of my recipe collection!
perfect dinner last night. thank you for this amazing super quick delicious recipe
This recipe is a keeper! it is a great meal, weeknight or not. The timing was spot on which I greatly appreciate. Will definitely make again
I had bread in the oven so prepared this on the stovetop. Browned the fish for a couple of minutes then sauted the shallot and onion and added the remaining ingredients. Returned the fish to the skillet and spooned the sauce over while it cooked for a few more minutes. DELICIOUS! Thanks for a great recipe.
Soooo delish! Made this with your easy baked risotto, foil pack carrots and Outback copycat rolls. 5 stars!
This was sooo delicious and easy! Perfect quick meal for a uni student like me 🙂
Awesome Natasha!!! That’s great! N x
Just delicious and sooo easy
Yes! That was so delicious. Made it exactly as you said to and it was so yummyyy!
Would winter skate be good in this recipe. Trying to find meals for my husband who requires a good diet, and has medical issues, trying to please him all I can.
WOWZA! So quick, easy and so very delicious!!
Just made and served this with pickerel (big huge pieces). It came out delish. I think i can just cut back on the lemon a tad. Broil last minute for golden crisp edges would have been nice touch. Dash of parm topping to finish. My wife approved. Thank you for this recipe!! Much love.
