This Lemon Butter Sauce for fish is outrageous – 3 minutes, 2 ingredients, totally restaurant worthy.

The secret is browned butter – calledΒ Beurre noisetteΒ in French. Learn how to pronounce it so you can loftily tell your family and friends β€œwe’re having French tonight!” (But don’t tell them how simple it is?)

Restaurant-style Lemon Butter Sauce for Fish!

Great quality fish is not cheap. But worthy of investment because:

  • it’s good for you;

  • a beautiful piece of fish requires very little done to it to make a meal that you’d pay serious $ for at a fancy seafood restaurant; and

  • they’re quick to cook.

And so I present to you, your new favourite posh-yet-easy-and-super-quick way with fish: Pan fried until golden then drizzled with a 3 minute Lemon Butter Sauce that you’re going to go nuts over.

The Lemon Butter Sauce

The Lemon Butter Sauce is just made with butter and lemon.Β But it’s not β€œjust” butter and lemon.

It’sΒ brown butter and lemon.

If you’re new to brown butter, this is going to change your world – it’s addictive. Brown butter is everything you love about melted butter, boosted with an incredible nutty, toasty aroma.

The French call itΒ Beurre noisette.Β The literal translation is β€œhazelnut butter”, and even though hazelnuts don’t come into the equation at all, we get it. πŸ™‚

How to make Lemon Butter Sauce

3 minutes, 3 steps, 2 ingredients:

  • Melt butter;

  • Leave until the butter turnsΒ brown and the smell suddenly changes and becomes nutty – about 3 minutes;

  • Stir through lemon juice.

The recipe video is helpful if you’re a first timer to browned butter – especially the pre and post comparison.

Quick Tips

While brown butter is simple to make, if it’s on too high a heat, it can go from nutty perfection to burnt in seconds. So here are a few quick tips:

  • Use a silver based small skillet or pot so you can see when the butter changes colour;

  • Make the Lemon Butter Sauce before the fish so you can concentrate on getting it right. It stays warm for up to 30 minutes – but if you are delayed and it solidifies, it only takes 10 seconds in the microwave to melt it back to its original state; and

  • Don’t try to make the Lemon Butter Sauce in the same skillet as the fish – the pan will be too large.

Use sparingly – it’s rich!

And you don’t need much – this stuff is rich!Β The recipe makes slightly more than you need because running out of sauce in the middle of dinner is dismal, but in all honesty, my standard serving is 1 tablespoon of Sauce per fillet of fish.

It looks a lot browner in the bowl than it does when you drizzle it over the fish. Which is actually perfect – it’s a bright yellow Lemon colour once drizzled. πŸ™‚ If it was just plain melted butter, you wouldn’t have that same intense deep yellow colour that you see on the plate – nor would it pool on the plate like in the photo below.

The fish fillet is pictured in this post withΒ the Kale and Quinoa Salad I published on Monday. πŸ™‚ Keeps forΒ daysΒ in the fridge, my friends! Don’t think of it as a trendy β€œhealth food” salad. It’s just a darn tastyΒ filling salad that just happens to star 2 superfoods. Tested and proven!

Here are a few more ideas for things to serve this fish with:

  • Mashed potato or mashed cauliflower (for a low carb option)

  • For a true indulgent restaurant experience, try Paris Mash – the richest, creamiest mashed potato in the world

  • Curried Basmati Rice – this aromatic pilaf would be terrific paired with the fresh fish flavour

  • A garden salad or leafy greens with French Vinaigrette or Italian Dressing

  • Broccoli Salad or Magic Broccoli (the best roasted broccoli ever!)

Recipe VIDEO above (helpful for pre-post browned butter). A Lemon Butter Sauce with Crispy Pan Fried Fish that would be perfectly at home in a posh restaurant, yet is so quick to make at home! Browning the butter gives the sauce a rich, nutty aroma which pairs beautifully with fresh lemon, as well as thickening the sauce and giving it a gorgeous golden colour.

Ingredients

Lemon Butter Sauce:

  • 60 g / 4 tbsp unsalted butter , cut into pieces
  • 1 tbsp fresh lemon juice
  • Salt and finely ground pepper

Crispy Pan Fried Fish:

  • 2 x thin white fish fillets (120-150g / 4-5oz each), skinless boneless (I used Bream, Note 1)
  • Salt and pepper
  • 2 tbsp white flour
  • 2 tbsp oil (I use canola)

Serving:

  • Lemon wedges
  • Finely chopped parsley, optional
Prevent screen from sleeping

Instructions

Lemon Butter Sauce (see video):

  • Place the butter in a light coloured saucepan or small skillet over medium heat.
  • Melt butter then leave on the stove, whisking / stirring very now and then. When the butter turns golden brown and it smells nutty – about 3 minutes, remove from stove immediately and pour into small bowl. (Note 2)
  • Add lemon juice and a pinch of salt and pepper. Stir then taste when it has cooled slightly. Adjust lemon/salt to taste.
  • Set aside – it will stay pourable for 20 – 30 minutes. See Note 3 for storing.

Crispy Pan Fried Fish:

  • Pat fish dry using paper towels. Sprinkle with salt & pepper, then flour. Use fingers to spread flour. Turn and repeat. Shake excess flour off well, slapping between hands if necessary.
  • Heat oil in a non stick skillet over high heat. When the oil is shimmering and there are faint wisps of smoke, add fish. Cook for 1 1/2 minutes until golden and crispy on the edges, then turn and cook the other side for 1 1/2 minutes (cook longer if you have thicker fillets).
  • Remove immediately onto serving plates. Drizzle each with about 1 tbsp of Sauce (avoid dark specks settled at the bottom of the bowl), garnish with parsley and serve with lemon on the side. Pictured in post with Kale and Quinoa Salad.

Recipe Notes:

1. I like using this sauce for thin fillets because I find you get the best sauce to flesh coverage, and also because thin fillets tend to mean less fish (the sea bream in the photos are only around 120g/4oz each) so you’re not having to pour over loads of Sauce (it is quite rich). I also love how the edges of thin fish fillets go nice and crispy!
Having said that though, this sauce is suitable for almost any white fish fillet, but I’d avoid rich, oily fish like salmon and mackerel.
FROZEN FISH is also fine – thaw thoroughly and pat very well with paper towels to remove excess water.
2. BROWNING BUTTER: At first, it will spit a bit (water in butter cooking out), then it will bubble, then it will foam. Little brown bits will start appearing on the base of the pan – THEN you will smell the nuttiness. Smell is the most important sign – when it smells amazing, take it right off!
3. Storing Brown Butter: You’ll only need around 1 tbsp of Sauce per serving – it’s very rich – but this recipe makes slightly more because it’s hard to make a smaller quantity. Use leftovers to jazz up vegetables, mashed potato, or even spread on toast! Β Refrigerate and use within 1 week, or freeze. To use as Sauce, microwave in 10 second increments.
4. GENERAL NOTE: If you’re an experienced cook, you can try your hand at making the sauce in the pan after cooking the fish. First wipe it clean (yes you lose pan flavour, but it’s nice to have a β€œclean” looking sauce), lower heat then make the sauce once the pan has cooled. I personally find it easier to make the Sauce first in a smaller pan – easier to control colour change. Also I like using my black non stick pan for the fish and you can’t see the colour of the butter in dark coloured pans.
5. Nutrition per serving, assuming 1 tbsp of Sauce (it’s a rich sauce, you don’t need much) and assuming 1/2 tbsp of oil is discarded after cooking the fish (my estimation by scraping out remaining oil). The fish weight seems small but it looks larger on the plate because I used a thin fillet (bream).Β

    Hi Nagi, I am wondering if you could make the brown butter sauce and use it in a packet of fish and veggies covered and cooked in foil or would it burn the brown butter? I have some recipes for cooking fish in a packet in the oven and thought this might be a great addition. I guess if there is a chance that it could burn since it is browned butter, then I could just add to the packet when it comes out of the oven. It wouldn’t be the same as cooking in it but I think it would be delicious any way you can use it…lol! Thanks for your super recipes!!

    Thank you for your attention to detail. I do have a lot of experience in the kitchen, but I like that you did step-by-step instructions, like patting the fish dry before dredging in flour (and then shaking off excess flour). And heating the pan before adding the oil to it. I especially liked where you said that the fish would not stick if you wait for it to unstick itself–totally right! Husband and I loved this recipe and will make again. We made it with fresh-caught speckled trout from the Gulf of Mexico! Thanks! We plan to try more of your recipes!

    Great recipe and super easy. I made whiting in the oven, seasoned lightly with cajun seasoning. Added a little coriander and black pepper in the sauce which was good, but was also good without.

    My butter sauce didn’t turn out too well….first, I only had salted butter (figured I wouldn’t add salt at the end). It immediately foamed up and was hard to watch the mixture. I let it go 3 min and took off. After I put the very dark liquid in a bowl and added lemon juice, it was like a chemical reaction…..foaming and spitting fiercely. After, it was very bitter.

    Was it the butter? Something else? I’ll try again with the correct butter.
