Knorr Bearnaise Sauce Recipe: Homemade Richness in 10 Minutes

This Knorr Bearnaise sauce recipe transforms classic French technique into a 10-minute masterpiece—rich, velvety, and packed with depth. The secret lies in a proper vinegar reduction and careful butter emulsification, elevated just enough by Knorr's concentrated umami touch to bridge traditional elegance with modern convenience.

I developed this version after years of perfecting the sauce, seeking that perfect balance between authenticity and accessibility.

The foundation starts with a shallot-vinegar reduction, simmered until syrupy and aromatic. Knorr's flavor enhancer joins at the end, not as a substitute but as a subtle amplifier—enhancing the sauce's natural depth without overpowering its delicate herbaceous notes.

What makes this version special is how it maintains that signature buttery, tangy finish while cutting prep time dramatically.

What you'll end up with is a smooth, luxurious sauce that clings beautifully to steak, fish, or even roasted vegetables. The butter emulsifies perfectly, creating ribbons of golden richness that contrast against the sauce's bright vinegar base. This isn't just a shortcut—it's a restaurant-quality result that still feels homemade.

Best of all, the sauce keeps well in the fridge for up to 5 days, making it perfect for meal prep. Whether you're searing a filet mignon or drizzling over asparagus, this Bearnaise delivers bold flavor with minimal effort. Let's make it—your taste buds will thank you.

Ingredients for knorr bearnaise sauce

Ten ingredients transform classic Bearnaise into a restaurant-quality sauce—rich, velvety, and ready in minutes.

The shallots and vinegar form the sauce's aromatic backbone. Look for fresh shallots at the market—they should be firm and pale purple. If you can't find them, sub with 1/4 cup finely chopped yellow onion, but shallots add that delicate sweetness. The vinegar? White wine vinegar is ideal—avoid balsamic or apple cider, which can overpower the sauce's delicate balance. For the butter, European-style unsalted melts more smoothly than American brands. I always grab mine from Whole Foods or Costco for the best quality.

No fresh tarragon? Dried tarragon works at 1/4 the amount, but it lacks the bright, anise-like flavor. The chives add freshness, but green onion or parsley can substitute in a pinch. Knorr's flavor enhancer is non-negotiable here—it amplifies the sauce's depth without overpowering. For a lighter version, replace half the heavy cream with whole milk, though the sauce won't be as luxurious. The olive oil should be light and fruity—California extra-virgin brands like Corto or Bertolli work perfectly. Avoid peppery varieties, which can clash with the butter's richness.

This sauce is a 5-day fridge champ, but for longer storage, freeze in ice cube trays—perfect for single portions. Reheat gently in a saucepan over low heat, whisking constantly to avoid breaking the emulsion. For a restaurant-worthy finish, strain through a fine-mesh sieve before serving. The sauce thickens as it cools, so add a splash of warm water if it becomes too stiff. Trust me, the first time you drizzle this over perfectly seared steak, you'll never buy store-bought again.

Step-by-step instructions for Knorr Bearnaise sauce

This homemade version delivers restaurant-quality richness in record time—no fancy techniques required.

In a small saucepan, combine the 3 whole shallots (finely minced) and 0.5 cup white wine vinegar. Bring to a gentle simmer over medium heat and cook for 5-6 minutes until the shallots soften and the mixture reduces by about half. You're looking for a syrupy consistency that coats the back of a spoon—this forms the flavor base.

Strain the reduction through a fine-mesh sieve into a clean bowl, pressing gently on the shallots to extract every bit of flavor. Discard the solids. This step ensures your sauce will be silky smooth rather than textured. Let the strained liquid cool slightly while you prepare the next components.

In a separate small saucepan, melt ½ cup of the unsalted butter over low heat until just liquid. Remove from heat and stir in 1 tsp Knorr Flavor Enhancer, 0.25 cup chopped fresh tarragon, and 0.25 cup chopped fresh chives. Let the mixture steep for 5 minutes, allowing the herbs to infuse the butter with their bright, anise-like notes.

Strain the herb-infused butter through a fine-mesh sieve into a heatproof bowl, pressing firmly to extract all the flavor. Discard the herb solids. Keep this bowl over a pot of barely simmering water (double boiler) to maintain a consistent temperature around 160°F—this is critical for successful emulsification later.

Return the strained shallot-vinegar reduction to the same small saucepan and bring to a gentle simmer over medium-low heat. Whisk in 0.25 cup heavy cream and 0.5 tsp Diamond Crystal Kosher Salt, then simmer for 2-3 minutes until slightly thickened but still pourable. Remove from heat and let cool for 1 minute—the mixture should be warm but not hot.

While the sauce cools, melt the remaining ½ cup unsalted butter in a separate small saucepan over low heat until completely liquid. This butter will be used to temper the sauce and create the signature emulsified texture. Keep it warm but not bubbling.

With a hand mixer or whisk, begin blending the warm shallot-cream mixture on medium speed. Slowly drizzle in the melted butter in a thin, steady stream while continuing to blend. This gradual addition is key—adding butter too quickly will cause the sauce to break. You'll notice the mixture transform from separate liquids into a glossy, velvety emulsion.

Once all the butter is incorporated and the sauce reaches a mayonnaise-like consistency, stir in 0.25 tsp freshly ground black pepper and 0.25 cup extra-virgin olive oil. The olive oil adds a subtle fruity balance to the richness. Taste and adjust seasoning if needed—this sauce should be tangy, herby, and perfectly balanced.

Transfer the finished sauce to a clean bowl and cover the surface with plastic wrap pressed directly against the sauce to prevent a skin from forming. Let it sit at room temperature for 5 minutes to allow the flavors to meld completely. This resting period ensures the sauce reaches its ideal texture and flavor profile.

Serve the Knorr Bearnaise immediately over grilled steaks, poached fish, or roasted vegetables. The sauce should be silky smooth, with a glossy sheen and a perfect balance of tangy, herby, and rich flavors. If the sauce thickens slightly upon standing, simply whisk in 1-2 teaspoons of hot water to restore its ideal consistency.

Essential equipment for this recipe

Emulsification Tools

For perfect emulsification, a hand mixer (like the Cuisinart SM-50BC) is my go-to—it blends the butter into the sauce smoothly without overworking. If you prefer manual control, a whisk works too, but you’ll need steady hands and patience.

The key is blending on medium speed while slowly drizzling butter to avoid breaking the emulsion. 🔥

Double Boiler Setup

A double boiler is essential for keeping the butter-infused herbs at a consistent 160°F. I use a stainless steel heatproof bowl (like those from Le Creuset) placed over a saucepan with 2 inches of simmering water.

Never let the water boil—just maintain a gentle steam. This precision is what separates homemade sauce from store-bought.

Fine-Mesh Strainer

A fine-mesh sieve (such as the OXO Good Grips) is non-negotiable for straining the shallot reduction and herb-infused butter. It removes all solids, ensuring your sauce is silky smooth.

Press the solids gently with a spoon to extract every last drop of flavor. I’ve tried cheesecloth, but it can trap too much liquid and dilute the sauce.

Heatproof Bowls

Use heatproof glass or stainless steel bowls (like Pyrex) for all temperature-sensitive steps. These materials distribute heat evenly and won’t crack under sudden temperature changes. Plastic bowls can warp or melt, ruining your emulsion. I keep a set of three heatproof bowls dedicated to sauce-making for quick cleanup.

Saucepan Selection

A heavy-bottomed saucepan (such as All-Clad) prevents hot spots that can scorch the shallot reduction. I avoid nonstick pans—they can react with vinegar and impart off-flavors. For the butter infusion, a small, wide saucepan (like Calphalon) ensures even melting and better heat control.

Storage Containers

For leftovers, store sauce in airtight glass containers (like Mason jars) to preserve freshness. Plastic containers can absorb odors and affect the sauce’s flavor.

Label containers with the date—this sauce keeps for 5 days in the fridge or 3 months in the freezer (in ice cube trays for portion control). ✨
