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.

Life of Dozer
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!!
First time making this and it was absolutely delicious. And so easy. I found that the sauce was perfect for two fillets of seabass (so I would double the quantity of sauce if using four fish fillets). I sautéed the shallots to soften them a bit before adding this to the sauce. I accompanies this with the sautéed green beans with garlic (another RTE recipe). I admit I even licked the plate! Definitely a winner. I will add some capers to the sauce next time per some of the comments.
I was so saddened to hear about Dozer’s passing. You were such a great mom to him. I think you should know this fish was absolutely delicious!! The sauce was the star and I am going to make it to spoon over veggies too! I threw in a couple of tablespoons of capers and they added a nice flavor. We finished every bite of the cod! Thank you so much, your recipes are always delish!!
I made this tonight for myself for Valentine’s Day dinner and omg, it was so so delicious! I used Halibut fish and also made whipped cauliflower mash with green beans and it was the perfect combo and blend of flavors. Def making it again, 10/10!
I made this for the first time for a dinner party. It’s a simple recipe, but everyone said it was delicious and restaurant quality. I definitely recommend giving it a try! This one is being added to my repertoire. I read a few comments beforehand that said to make a bit more sauce, and that was a brilliant idea and really helped – so I’d do this!
Thank you, RecipeTinEasts, for such a lovely dinner recipe! The flavors are so simple, yet outstanding! We served the fish and delicious sauce over rice with steamed snow
peas and a crisp white wine!
Absolutely DELICIOUS! Came out perfect the first time I tried it at a partyGot great comments. Thanks 😊
This was really good! For the Americans/Canadians: I used half & half, regular yellow onion, and frozen cod from Costco. I did not add any salt. Next time I’ll reduce the dijon, but my husband thought it was perfect. Very easy. Will make often.
Wonderful recipe. I substituted about two tablespoons of finely chopped capers in lieu of the onion. Gave the sauce a really nice tangy, savory flavor.
I tried this recipe with frozen sea bass and it was amazing i was just refering back to it since i have salmon i wanted to use the same recipe for NYE but i just learned it is not ideal with salmon. Any salmon recipe you recommend that tastes as good as this??
Absolutely delicious. My husband loved it. I used Basa fillets.
Made this last night for my husband and I, and while it tasted very good, we were both a little put off by the firmness, for lack of a better word, of the shallots. In a sauce such as this, I think you would normally sauté the shallots first, since you don’t expect there to be a “bite” in the finished dish.
Very, very tasty. Totally agree with doubling the sauce. It’s a keeper and already on repeat in our household.
Made this recipe 10+ times now and it never fails to impress. My only tip would be to double the quantity of the sauce, cook some pasta whilst the fish is cooking, remove the fish and then stir the sauce through the pasta. Some frozen peas added at the end of the pasta cook makes it a delicious, easy and complete meal. I’ll be trying it with prawns tonight!
This was so much better than I expected, quick, easy and delicious. I did add the lemon zest for extra kick and it was worth it.
Bloody beautiful!!
Looking to make this today, would this work with cod?
Perfect recipe! First time I used Bluebone, today I am using Snapper.. Family favourite!
Delicious!! I used a 1kg bag of frozen basa fillets, my baking dish was probably a bit crowded but was still very nice. Served with baked cauliflower and a rocket/parmasen salad.
Silly simple but the result is Restaurant Quality!
Well done, Nagi.
😘
This is the 4th time making it and every time we say, why don’t we make this more often?!? It’s so good. We put the leftover sauce over our rice/rice pilaf.
