One of my favorite meals is filet mignon with Béarnaise Sauce. I actually love it so much it was served at my wedding many years ago. There is something so rich and decadent about it, but it’s also insanely easy to make.

Many people have never even attempted making it because the name alone just sounds intimidating, and if that’s you, I promise it’s completely doable.

This recipe is quick and very easy to put together in just 10 minutes. Also, if you struggle with how to add more healthy fats to your Keto diet, this sauce will get you there because in addition to being rich, buttery and creamy, it’s loaded with healthy fat.

🔪 How to Make Béarnaise Sauce

Add the white wine, white wine vinegar, lemon juice, shallots, salt, pepper, and half of the tarragon leaves, in a saucepan. Bring to a boil and simmer over medium heat for a few minutes, until the mixture is reduced to just under ¼ cup.

Add the mixture to an immersion blender and allow to cool for a few minutes.  Add the egg yolks and mix for a few seconds.

Add the butter in a heatproof cup with a pour spout and heat up in the microwave (or heat directly in another saucepan).

Once the butter is hot, the milk solids will sink to the bottom, discard those and keep the clarified butter to use in the sauce. You should end up with just over ¾ cup.

Tip: This is the easiest way to make clarified butter and it’s great to have on hand for dipping seafood like crab and lobster in. The absence of the milk solids also gives it a higher smoking point, which is great to use when making pancakes, so they don’t burn.

Then VERY SLOWLY stream in the hot butter while mixing with the immersion blender stick.

Tip: The butter must be hot in order to cook the raw egg yolks. Slowly streaming it also helps to emulsify the sauce and thicken it up. Don’t rush this step, otherwise it won’t come together and you’ll have to start all over.

Continue mixing, gently pulling up and down until the sauce is emulsified and perfectly thickened. Add the remaining tarragon and pulse for 2 seconds.

If the sauce is too thick, mix in a tiny bit of hot water.

Serve immediately (the sauce will thicken as it cools) over the protein or veggies of your choice.

Store leftovers in an airtight jar in the fridge for a few days. When you’re ready to use it again, reheat it in the microwave for about 20 seconds, just to take the chill out and loosen it up some. Whisk in a little hot water until you get the right consistency and you’re good to go!

What is Béarnaise Sauce?

Béarnaise is a rich and creamy yellow French sauce made from a reduction of vinegar and wine mixed with shallots and tarragon, thickened with egg yolks and butter. It is often served with steak at fine dining restaurants and high-end steakhouses.

Is Béarnaise Sauce Keto? Does Béarnaise Sauce Have Carbs?

Béarnaise sauce is most definitely keto friendly, due to it’s high healthy fat content and very low carbs. In fact, it’s one of my favorite ways to add more healthy fats to my meals that happen to be lacking in fat. Serve it over veggies and you’ve hit your macros easily!

What is the Main Herb of Béarnaise?

Wonderfully unique and delicious tarragon! It’s very underutilized and underappreciated in my opinion, but adds fantastic flavor to chicken, fish and even baked herb bread.

What is the Difference Between Béarnaise and Hollandaise sauce?

Both sauces have an egg yolk and butter base with white wine, but Hollandaise Sauce, also known as French Mother Sauce, uses lemon juice as the acid, where Béarnaise Sauce uses white wine vinegar instead.

In this recipe, I love both sauces so much, that I actually combined elements from both sauces to create one glorious sauce that can be used on so many different things. I’ve listed some great ideas below.

Does Béarnaise Have Raw Eggs?

While you start off with raw eggs, the heat from the butter helps to gently cook the eggs, making it safe to eat. This is why I specify in the directions, that the butter must be hot.
