Beurre Blanc (Recipe, Tips and Troubleshooting)
Click the stars to rate!
For a long time, I was nervous to try a beurre blanc sauce; I thought it was only for top chefs! But in reality, it’s super easy and a basic in French cuisine; a staple, even! Once you understand the “chemistry” behind it, it acts as a great base that you can vary to your heart’s content. Here, in my recipe guide, I’ve included all my little technical tips so you never miss a trick.

What Is Beurre Blanc?
Beurre blanc is simply an emulsion of butter and an acidic liquid (wine, vinegar or lemon). If you remember your chemistry lessons, fat and water don’t mix naturally. To achieve this, you need to create a bond between the two: this is called an emulsion, and it’s what happens when you make beurre blanc!
Beurre blanc is pronounced “bur BLAHN” (with a soft ‘r’ and a silent ‘c’) and literally translates to ‘white butter’ in French. So before getting down to technique, let’s start with the ingredients.
Ingredients For a Classic Beurre Blanc Sauce
To make beurre blanc, you need butter and acidic liquid. Here are the essentials for the traditional version:
- Butter: Use soft butter, cut into small cubes. Be careful to choose a quality butter with at least 82% fat content.
- White wine: This is the liquid base. Choose a dry white wine (Sauvignon, Chardonnay or Pinot Gris).
- White wine vinegar: I really like to use white balsamic vinegar, because it’s softer and more fragrant.
- Shallots : One or two, depending on size. They add the characteristic taste of beurre blanc. They are thinner than onions.
- Salt and pepper

My 5 tips for successful beurre blanc!
Before you get started, read these tips carefully. They’ll help you avoid the beginner’s mistakes I made myself in the early days!
- Prepare at the last minute: Sadly, beurre blanc doesn’t keep very long, and is difficult to reheat without breaking down. Ideally, it should be served straight away.
- Reduce the liquid base: Take the time to gently cook out the wine/shallot mixture until it’s syrupy. In my experience, this is what gives the sauce its character and helps the ingredients emulsify.
- Butter must be very cold: This is my number-one takeaway for you! Don’t take your butter out of the fridge until the last minute. It’s the thermal shock from the frozen butter in the hot reduction that creates a creamy texture.
- Add the butter a little at a time: If you add all the butter at once, the emulsion won’t set. I suggest adding the cubes one by one (or two by two), whisking well between each addition.
- Check the temperature: This is the only technical point. Never heat the beurre blanc above 149°F/ 65°C; otherwise the fat will separate out and the mixture will split. The ideal beurre blanc temperature range for perfect consistency is between 122 and 131°F (50 and 55 °C).

Ingredients
- 125 g soft butter cold and diced
- 1-2 shallots very finely chopped
- 100 ml dry white wine
- 50 ml white wine vinegar or white balsamic vinegar
- Salt and pepper
Instructions
- Pour the white wine, vinegar and shallots into a saucepan. Bring to the boil and reduce by half (or a little more) over medium heat until the liquid becomes syrupy.
- Reduce heat to minimum. Add the cold butter cubes one at a time, whisking vigorously between each addition to create an emulsion. Remove from heat, season with salt and pepper.
- To obtain a smooth texture, strain the sauce through a sieve (or chinois) to remove the shallot pieces. Serve immediately.
Notes
The Most Common Mistakes And How To Avoid Them
Although beurre blanc is super quick to make, it can go wrong very quickly. When learning to make a classic beurre blanc, I messed up a batch or two, but I quickly learned how to fix a broken butter sauce. Here are the most common mistakes I try to avoid:
Slicing the butter or splitting the sauce: This is the classic mistake. You notice it right away: the fat separates from the liquid and the sauce becomes oily. In my experience, this is often due to overheating a butter emulsion technique above 149°F/ 65°C.
My tip: Immediately remove the pan from the heat and add a tablespoon of iced water or cold liquid cream. Whisk vigorously and the emulsion should come back together.
The sauce becomes too runny: If your sauce doesn’t coat your spoon well and is thin, it’s probably because you didn’t reduce your wine-and-shallot base enough to begin with. That, or you didn’t add enough butter.
My tip: Next time, make sure your reduction is syrupy before adding the first cube of butter. In the meantime, add a few more cubes of butter and leave it to cool slightly.
A sauce that’s too thick: On the other hand, I’ve sometimes been too generous with the butter, or the sauce has cooled too much, and it becomes a little compact.
My tip: Add a teaspoon of white wine or warm water and whisk gently over very low heat to loosen the texture.
Too acidic: Depending on the wine or vinegar you use, the taste can be a little too pungent.
My tip: No need to start all over again! Add just a little more butter or a pinch of sugar to soften the acidity and rebalance the flavours.
What To Serve With Beurre Blanc?
I consider a beurre blanc an elegant sauce and I usually serve it classically, with delicate, low-fat foods to create that lovely contrast between creaminess, freshness and acidity.
Here are a few ideas for serving your French white wine butter sauce at home:
- Fish: A classic of French cuisine! The creaminess of the butter and the acidity of the white wine are delicious well with cod, pike-perch or salmon fillets. I also love it with seared scallops.
- Seasonal vegetables: In France, we often serve it over white or green asparagus in spring. I also love to pour it over steamed early vegetables (baby carrots, fresh peas or green beans), or even artichoke hearts.
- Shellfish: For a special occasion, serve your beurre blanc with grilled shrimps, langoustines or even half a lobster. The contrast between the sweet flesh of the shellfish and the acidity of the sauce is incredible!
- And don’t forget the starch! This sauce is perfect when drizzled over white rice or fluffy steamed potatoes.
Ideas for Variations on Beurre Blanc
Once you’ve mastered the beurre blanc base, it’s easy to have fun varying the flavours:
- Lemon version: Replace vinegar with lemon juice for a fresher sauce. I feel it’s perfect with oily fish like salmon or trout.
- Fresh herbs: I sometimes add snipped chives, dill or chervil just before serving.
- Spices: Infuse a few strands of saffron into the white wine, or add a pinch of Espelette pepper at the end for a spicy kick. Yum!
Great site for French cooking. Beurre Blanc is a wonderful addition to fish.
