The Ultimate Sauce For Seafood!
If you want to feel like a fancy restaurant chef (from home, no less!), make this foolproof lemon beurre blanc. One taste of this creamy, buttery lemon sauce and you’ll be spooning it over everything, especially elevated seafood recipes where the rich, creamy texture really shines. Though it’s great with chicken too!
The sauce finishes over low heat with a splash of heavy cream and cold butter slowly swirled in to create a beautiful emulsion. I love it spooned over tender, buttery sole meunière or a simple pan-seared Chilean sea bass. It’s pure elegance and will (rightfully) make you look like a total star in the kitchen! 👩🏻🍳👨🏼🍳

Expert Tips So Your Sauce Doesn’t Break!
Nobody wants a broken sauce. Here’s how to make sure it doesn’t happen to you!
- Add the butter slowly. Allow each cube of butter to melt into the sauce before adding more. I like to add 2-3 tablespoons at a time, but the butter must be cold!
- Monitor the temperature and be patient. When adding butter, keep the temperature over low heat, no higher.
- Do not let the mixture boil after adding butter. This will cause the sauce to separate.



A Classic Pairing with Seafood
Salmon, scallops, Chilean sea bass, shrimp, lobster! Really any fish or crustacean is improved upon with silky smooth lemon beurre blanc on top.
Keep the sides simple with sautéed or roasted vegetables, creamy, garlic-infused mashed potatoes, and crusty bread for soaking up the beautiful sauce.

Variations on French Butter Sauce
Once you’ve nailed down the method (most important), you can begin to play around with variations. Try adding fresh herbs—stir in one tablespoon of chopped, fresh herbs (dill, tarragon, or chives are fantastic) once the sauce has finished.
Don’t have white wine vinegar? Substitute with other vinegars, such as red wine, tarragon, or anything that is light in color (not balsamic). You can also make a beurre rouge by using red wine in place of white wine!

This bright, delicate sauce is truly luscious and will make you look like a well-trained restaurant chef. Be sure to give it a try and drop a ⭐️⭐️⭐️⭐️⭐️ rating and review to let us know what you think! (P.S. this one is already so loved by many readers!)

Equipment
Ingredients
- 9 Tbsp unsalted butter divided, cold, cubed
- 1 medium shallot finely chopped
- ½ cup dry white wine
- 2 Tbsp white wine vinegar
- 2 Tbsp fresh lemon juice about ½ large lemon
- 2 Tbsp heavy cream
- Kosher salt to taste
Instructions
- Sweat the shallot. Heat 1 Tbsp butter in a nonreactive saucepan over medium heat. Add minced shallot and cook until translucent, about 2-3 minutes.
- Add liquid. Pour in ½ cup white wine, 2 Tbsp white wine vinegar, and 2 Tbsp fresh lemon juice. Cook over medium-high heat till the mixture reaches a simmer. Reduce temperature to medium, then let the sauce thicken and reduce, about 4 minutes. Add the heavy cream, stir, then turn the heat down to low.
- Emulsify with butter. Add 2-3 Tbsp of cold, cubed butter. Swirl the pan (or whisk) until the butter has emulsified into the sauce. Repeat with remaining butter. Taste, then season with a pinch or two of Kosher salt, as needed. Serve immediately.
Notes
- Leftovers: When stabilized with heavy cream, beurre blanc will last for up to 3 days in a fridge. While beurre blanc can technically be frozen for up to 1 month, it just won’t have the same smooth consistency when thawed. I recommend enjoying it fresh.



This was a home run on the Chilean Sea Bass. I just wish it was a little more healthy! Thank you for the recipe.
A perfect combination! Agree, totally wish beurre blanc could be an every day occurrence, but alas, best saved for special occasions. Glad you enjoyed! xo, Ari
Alright, I’ll just say this, I don’t like extra sauces on my food. I didn’t even make this for myself. I simply asked my girlfriend what she might like with Chilean Sea Bass. She told me she liked a sauce like this.
I don’t care for sea food, so trying to make that, and trying to make this sauce was a new challenge for me, a way to test me.
She used to work at a high end restaurant in Pittsburgh and this was on the list of menu items they served. I followed the recipe and instructions word by word. The sauce not only held up during the prep, but almost 30 minutes later it still held strong. When I served it to her, she absolutely loved it. Said it was even better than the high end restaurant here.
I personally had to try it afterward and it still is not for me, but it didn’t matter. Her pallet is much more refined than mine when it comes to fine dining and I’m happy to simply impress her when I get the chance. For the record I added about a 1/4 teaspoon of kosher salt. For her it was enough….for me, I probably would have needed another half teaspoon. It was good enough for her to tell me to save the rest.
For that, I give this recipe 5 stars. I’m always looking for ways to up my cooking skills and this one is saved to my favorites now.
Happy I found this recipe because I’d have never considered making this for anyone until now.
Thanks for this wonderful feedback, David! I’m so glad your girlfriend loved it, and it sounds like you knocked it out of the park. Well done! xo, Ari
This was exactly what I wanted to go with my salmon. I’ve had it in a few restaurants and love the way it goes with it and with rice.
It was fairly easy to make and came together quickly. I had to sub the white wine vinegar with champagne vinegar.
Will definitely be making this again.
Thanks
Love hearing this, thanks so much! xo, Ari
I have not tried this recipe but am excited to find it. We eat often at Hopkins Ice House in Texarkana, and they serve what they call their Le Blanc sauce with their fish dinner. From the start, husband often ordered the fish, but gave me the sauce as he did not prefer it.
I, having ordered sweet potato with my dinner, tried it for dipping in his sauce. As you noted, above, I now want to pour it over everything.
Now I have a question: We make our own wines and some are grape from our own vineyard, but some are experimental country wines. Our lemon experiment went straight to vinegar very rapidly.
Of course, you may not know, but I wonder if that vinegar, which is still mildly alcoholic and lemony, would make this recipe turn out well? I feel silly asking, but even if you don’t know, I did want to plainly THANK YOU for publishing this recipe! <3
Hi Katharine! I’m sorry, I don’t know whether that would work or if it would make the sauce too acidic. If you’re willing, you could try two half batches of the sauce (one as written, one with the lemon vinegar) and do a side-by-side taste test. If it works out, you’ll know you can use that ingredient again int he future. And if not, you’ll still have some of the lemon beurre blanc (as written) to enjoy. xo, Ari
Perfect! A truly delicious and easy to make sauce that made my tastebuds sing. Thank you!
Thanks so much, Karen!! Love this will all kinds of seafood recipes! xo, Ari
Great sauce! It took me a while the first time to make but I’m sure next time it’ll probably be 20 mins
Also I doubled the recipe but used a stick n a half of butter (I’m on a diet and 2 sticks is crazy lol)
And the seasonings I just added a pinch of kosher salt, Italian herbs, and fresh dill
Love this, looks incredible. And so smart to double the recipe! Glad it worked with less butter. Enjoy! Ari
I added a little bit of fresh dill, tarragon and lemon zest. It’s phenomenal. Put it on top of flounder and crab that we just caught. It was perfect.
I love the addition of fresh herbs and lemon — sounds perfect! Thanks for sharing, Angi! Cheers, Ari
It was the perfect consistency and flavor for my fresh pan seared halibut! Thank you
I always love hearing this! Thanks, Sarah! This is my go-to sauce for any and all fresh seafood. Really glad you enjoy it too. Cheers, Ari
