Sauces & Condiments
This classic Knorr-inspired Béarnaise sauce delivers the velvety emulsion and aromatic herb freshness that elevates steak, fish, and vegetables to restaurant-quality. The secret lies in carefully balancing butter, egg yolks, and vinegar while maintaining a smooth, glossy finish—no shortcuts here.
I’ve refined this recipe over years to ensure the sauce remains stable, rich, and packed with tarragon’s signature brightness.
The foundation of a perfect Béarnaise starts with a proper reduction of white wine vinegar and shallots, which forms the acidic backbone before blending with egg yolks. A slow, gentle heat ensures the emulsion never breaks, while fresh tarragon and parsley add that unmistakable herbal depth.
Unlike store-bought versions, this sauce stays silky and flavorful even after reheating.
What sets this recipe apart is its foolproof emulsification technique, where butter melts into the yolk mixture in fine ribbons, creating a luxurious, golden sauce. The result is a velvety, tangy condiment that clings beautifully to grilled meats or roasted vegetables, adding a touch of elegance to any dish.
Store it properly in the fridge for up to 3 days, or freeze for longer use—just whisk gently before serving. Whether you’re serving a Sunday roast or a weeknight steak, this Béarnaise transforms simple proteins into something extraordinary. Let’s make it.
Ingredients for knorr bearnaise sauce
Nine essential ingredients transform into restaurant-quality Béarnaise sauce, perfect for steak and seafood.
| Ingredient | Amount | Notes |
|---|---|---|
| White Wine Vinegar 🍷 | ½ cup | High-quality, aged variety preferred |
| Shallots 🧅 | 2 whole | Finely minced, skin removed |
| Fresh Tarragon 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Flat-Leaf Parsley 🌿 | ¼ cup | Finely chopped, stems removed |
| Large Egg Yolks 🥚 | 3 whole | Fresh, room-temperature preferred |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed, high-fat content |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain preferred |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Cracked peppercorns preferred |
| Granulated Sugar 🍚 | 1 tsp | Fine grain for smooth texture |
The white wine vinegar forms the acidic backbone of this sauce, so aged, high-quality vinegar is non-negotiable—avoid cheap cooking vinegars. Shallots should be finely minced (a food processor works best) to dissolve completely into the vinegar reduction. Fresh tarragon is critical for that signature herbal brightness; dried tarragon lacks complexity and won't deliver the same depth. For the best results, source tarragon from specialty markets or grow your own—it's worth the investment. The parsley acts as a subtle bridge flavor, so Italian flat-leaf parsley provides the best texture and mild herbal note without overpowering.
No fresh tarragon? Dried tarragon at one-third the amount works in a pinch, though the flavor will be muted. Substitute shallots with 1/4 cup finely minced yellow onion if needed, but the flavor profile shifts slightly. For the egg yolks, room temperature is essential—cold yolks won't emulsify properly. If you accidentally use cold yolks, warm them gently over a double boiler before incorporating. The butter must be cold and cubed—adding it too quickly will cause the sauce to break. For a lighter version, reduce the butter to 1/2 cup, though the sauce will be less rich. Always whisk in the butter very slowly to maintain the emulsion.
This sauce must be used within 3 days when refrigerated, as the emulsion begins to separate over time. To reheat, gently warm over low heat while whisking constantly—never microwave, as this will cause the sauce to curdle. For longer storage, freeze in ice cube trays, then transfer to a sealed container. Thaw overnight in the fridge and whisk gently before use. The sauce thickens as it cools, so reheat only until just warm to restore its silky texture. Always strain through a fine-mesh sieve before serving to ensure a velvety finish.

Step-by-step instructions for perfect Bearnaise sauce
Master this classic French emulsion with precise technique and fresh herb balance.
Infuse the Vinegar with Shallots and Herbs
In a small saucepan, combine the 0.5 cup white wine vinegar, 2 whole shallots, 1 tsp granulated sugar, 0.5 tsp Diamond Crystal kosher salt, and 0.25 tsp freshly ground black pepper. Bring to a gentle simmer over medium-low heat and cook for 8-10 minutes until the shallots are completely tender and the liquid reduces by half. You'll notice the mixture takes on a deep amber color and develops an aromatic complexity—this is your flavor foundation.
Remove from heat and stir in the 0.25 cup chopped fresh tarragon and 0.25 cup chopped fresh flat-leaf parsley. Let the herb mixture steep for 10 minutes while covered. This infusion step is crucial—it imparts the signature herbaceous notes that distinguish classic Bearnaise. Strain through a fine-mesh sieve into a clean bowl, pressing gently on the solids to extract maximum flavor. Discard the solids and let the infused vinegar cool to room temperature.
Whisk Egg Yolks and Gradually Incorporate Butter
In a heatproof bowl, whisk the 3 whole large egg yolks until pale and slightly thickened. Place this bowl over a saucepan of barely simmering water, ensuring the bottom of the bowl doesn't touch the water. This double boiler method gently warms the yolks without scrambling them. The yolks should reach 160°F—just warm enough to thicken slightly but not cook.
With the yolks at this precise temperature, begin whisking continuously while slowly drizzling in the 1 cup cold unsalted butter, 1 tablespoon at a time. Start with a very slow stream—this gradual incorporation is what creates the stable emulsion. The mixture will transform from a thin liquid to a thick, creamy sauce as the fat emulsifies with the yolks. This process should take 5-7 minutes of constant whisking. If the sauce breaks (separates), immediately whisk in 1 teaspoon of the reserved herb-infused vinegar to re-emulsify.
Incorporate the Herb-Infused Vinegar
Remove the bowl from the double boiler and let it cool slightly for 2 minutes. The sauce should now be thick and glossy. Gradually whisk in the cooled herb-infused vinegar, 1 tablespoon at a time, until fully incorporated. The sauce will lighten in color and develop its signature tangy-sweet balance. Taste and adjust seasoning with additional kosher salt or black pepper if needed—Bearnaise should be bright, balanced, and herb-forward.
For a silky texture, strain the sauce through a fine-mesh sieve into a clean saucepan. This removes any potential lumps and ensures a velvety consistency. Place the saucepan over low heat and gently warm, stirring constantly, until it reaches 150°F. The sauce is now ready to use immediately or can be kept warm in a thermos for serving. For best results, use within 2 hours of preparation, as the emulsion may separate over time.
Pro Tips For Making Knorr Bearnaise Sauce
- Cook Shallots Slowly: I learned this the hard way—charred shallots ruin the sauce. Simmer them in the butter until they’re translucent, not golden, or you’ll end up with bitter bits. Keep the heat low and stir often; patience here means a silky texture later.
- Strain Twice: The first strain removes the shallots, but the second—through a fine-mesh sieve—catches those stubborn herb stems and tiny bits that make the sauce gritty. Skip it, and you’ll taste every piece of tarragon stem in every bite.
- Temper Yolks Like Your Life Depends on It: Warm the yolks gradually with the emulsion, a splash at a time, or they’ll curdle faster than you can say “ruined sauce.” Use a whisk and go slow—this isn’t the time to rush, even if you’re impatient like me.
- Use Cold Butter: Cold butter blends smoother and keeps the sauce from breaking. Cut it into chunks, let it soften slightly, then fold it in at the end—no melting ahead of time. The result? A glossy, stable sauce that won’t separate when it hits the plate.

Herb-Forward Variations
Swap tarragon for fresh thyme and rosemary to create a Provençal twist—simmer 1 sprig each with the vinegar reduction for 5 minutes before straining. Add ½ tsp dried oregano to the final whisked sauce for an Italian-inspired Bolognese Béarnaise, perfect over grilled lamb chops. 🌿
Spicy Kick Options
For heat lovers, stir in ½ tsp cayenne pepper or 1 tsp hot honey during the final whisking stage. For smoky depth, add ½ tsp smoked paprika to the vinegar reduction.
I like adding a pinch of chipotle powder for a subtle Mexican-inspired warmth that pairs beautifully with grilled shrimp. 🌶️
Lighter Versions
Reduce butter to ½ cup and replace with ¼ cup olive oil for a lighter Mediterranean version. Use lemon zest instead of sugar and add 1 tbsp fresh dill to the herb infusion.
This works wonderfully with roasted vegetables or grilled fish. For a dairy-free option, substitute butter with avocado oil and use aquafaba (chickpea brine) instead of yolks—though texture will be slightly thinner. 🥑
Sweet & Tangy Twist
Add 1 tbsp honey or maple syrup to the vinegar reduction for a sweet-and-sour Béarnaise that complements pork tenderloin or glazed carrots. I also like adding ½ tsp vanilla bean paste to the final whisked sauce for a luxurious touch.
This variation balances the richness of butter with bright acidity and natural sweetness. 🍯
Dairy-Free Adaptation
Replace butter with vegan butter or coconut oil for a dairy-free version. Use 1 tbsp cornstarch mixed with 2 tbsp cold water to stabilize the emulsion instead of egg yolks.
For extra richness, add 2 tbsp tahini** to the final sauce—this adds a nutty depth that works well with roasted vegetables or grilled tofu. 🌱

Frequently asked questions
Why does my homemade Bearnaise sauce keep breaking?
The most common causes are adding butter too quickly or heating the egg yolks too fast. Always whisk constantly and add butter 1 tablespoon at a time while maintaining a gentle heat. If it breaks, immediately whisk in 1 teaspoon of the herb-infused vinegar to re-emulsify. Cold yolks or butter can also cause separation—ensure both are at room temperature before starting.
Can I make Bearnaise sauce without a double boiler?
Yes! Use a heatproof bowl placed over a saucepan of barely simmering water, ensuring the bowl doesn't touch the water. If you don't have a double boiler, a metal bowl works perfectly. The key is maintaining gentle, indirect heat to warm the yolks to 160°F without scrambling them. A thermometer helps monitor temperature precisely.
What's the best way to reheat leftover Bearnaise sauce?
Never microwave it—this will cause the emulsion to break. Instead, place the sauce in a clean saucepan over low heat and whisk constantly until just warmed to 150°F. Add a splash of cold water if it thickens too much. For best results, use the sauce within 2 hours of reheating, as the emulsion may weaken over time.
How can I make this sauce lighter or dairy-free?
For a lighter version, reduce butter to ½ cup and replace with ¼ cup olive oil. For dairy-free, substitute butter with avocado oil or vegan butter and use 1 tbsp cornstarch mixed with 2 tbsp cold water to stabilize the emulsion. The texture will be slightly thinner, but still flavorful.
What's the secret to getting that perfect golden color?
The golden hue comes from properly reducing the vinegar with shallots and sugar until it's deep amber. Also, ensure your butter is high-fat content (like European-style) and whisk it in slowly while maintaining a smooth, continuous ribbon. The final straining step removes any potential discoloration from the herbs.
