Easy Bearnaise Sauce in a Blender

There’s nothing more satisfying than beautifully prepared beef that is drizzled with a buttery, creamy Easy Bearnaise Sauce. Not only will this recipe tantalize your taste buds, but will give you a restaurant-worthy sauce that is both delicious and uncomplicated. 

Boy did I use to be intimated by the daunting task of making a bearnaise sauce. It seemed I could never get the whisking in of the butter quite right. It would result many times in the most unpredictable and disappointing conclusion. I literally just about gave up on the notion.

And then wonder of all wonders happened. Somewhere I heard that you could make an Easy Bearnaise Sauce in a blender or food processor. What? No more whisking in a double boiler? It’s true! This recipe is simple enough for a novice but brings the feel of an expert.

What is Bearnaise Sauce

Bearnaise sauce is an “offspring” of the beloved hollandaise which is one of the so-called five “mother sauces” in the French world.  Both are a luxurious sauce that enhances whatever dish they’re served with. They’re similar in appearance but differ in flavor because of the ingredients. 

What are the ingredients of this Easy Bearnaise Sauce?

Acidics. Dry White Wine, Champagne Vinegar, and Lemon Juice. These acids provide a balance to the richness of butter. They’re also added to help keep the egg yolks from curdling. 

Shallot. Shallots have a sweet but mild flavor with a hint of garlic which is why they work great in the bearnaise sauce. They’re not overpowering but hang subtly in the background to enhance the overall flavor. 

Whole Black Peppercorn. These ebony little creatures release spice notes of intense, fruity pungency into the sauce. It’s quiet in its application, but noticeably missing if left out. 

Fresh Tarragon. Tarragon, in my opinion, is what makes this Easy Bernaise Sauce worthy of acclamation. The licorice-like flavor it distributes throughout makes it so profoundly delicious. Leave this out, and you are left with a somewhat bland sauce.

Egg Yolks. The egg yolks are what helps thicken the sauce. Remove your eggs from the refrigerator an hour or two ahead of time and let them come to room temperature. 

Clarified Butter. Clarified Butter is butter that contains ONLY butterfat, no milk solids or water as does regular butter. In Sauces, James Peterson says “clarified butter gives a thicker and smoother sauce while whole butter is airier, runnier, and more buttery tasting.” You can use either one but with the understanding that the consistency will be different. Culinaryhill.com has a great link on how to clarify your own butter.

Making Bearnaise Sauce the Easy Way

1. Simmer and reduce the wine, vinegar, shallot, lemon juice, tarragon, and peppercorns.

This is where the distinct flavor of this Easy Bearnaise Sauce originates. Combine these ingredients and bring to a low boil, then turn down the heat and simmer until it is reduced by half. It will take 10-15 minutes. Remove from the heat and strain through a metal sieve. Use a spoon to press out all the liquid. Set aside and let cool. 

2. Use a blender to combine the liquid, egg yolks, and extra tarragon. 

This is where “easy” begins. No double boiler, no whisking until your arm falls off, and no more failed bearnaise sauce. Enter the magic of the blender. Add the reduction liquid, beaten eggs, and extra tarragon to the blender. Blend for about 30 seconds.

3. Emulsify Melted Butter into the above mixture. 

Melt the butter in the microwave for 45-60 seconds until it is hot and bubbling but be careful not to burn. Open the spout or remove the center stopper of the blender. Turn the blender on high and pour the hot butter through the opening in a slow steady stream. The sauce should have the consistency of thin mayo. This process should take about 30 seconds. Blend for another 10 seconds once all the butter is in.

If it is too thin, blend for another few seconds. If it’s too thick, thin it down with a small amount of water.

Note: The heat from the butter is used to cook the egg yolks. But to be fully on the safe side, I recommend using pasteurized eggs. I have instructions on my Aged Eggnog post on how to properly pasteurize eggs. You can also buy pasteurized eggs as well at Whole Foods or Sprouts.

Can this Easy Bearnaise Sauce be reheated?

It’s best to serve Bearnaise Sauce immediately. But if you do have leftovers, it can be refrigerated and then reheated. 

Two ways to reheat: 1) Spoon the cold sauce into a double broiler and simmer it over medium heat whisking it continually until the sauce is warm. 2) Add the refrigerated sauce to a microwave-safe bowl. Heat at 50% power in 15-second intervals, making sure to whisk in between intervals. Be careful to not overheat.
