Knorr Béarnaise Sauce Recipe: Classic French Flavor in Minutes

This classic French sauce elevates any dish with its rich, tangy depth and aromatic tarragon. I’ve refined this method to capture the authentic flavor without the traditional complexity.

The key is balancing the acidity of vinegar with creamy butter and fresh herbs. A foolproof technique ensures the emulsion stays smooth and velvety, just like the original.

You’ll achieve a restaurant-quality sauce that pairs perfectly with steak, fish, or vegetables. The tarragon and shallots create layers of flavor that make every bite unforgettable.

No advanced skills required—just simple steps and precise timing. This is Béarnaise as it was meant to be.

Ingredients for Knorr Bearnaise Sauce

Classic French ingredients create a rich, velvety sauce with aromatic depth and tangy brightness.

The tarragon is non-negotiable here—fresh tarragon has a distinct anise-like flavor that dried simply can’t replicate. Whole Foods or Trader Joe’s usually carry it in the herb section. For the white wine vinegar, good quality brands like Colavita or Lucini make a difference. Shallots should be firm and dry, never sprouting. Use a dry white wine like Sauvignon Blanc (whatever you’d drink).

No tarragon vinegar? White wine vinegar plus a pinch of dried tarragon works. Out of white wine? Substitute dry vermouth for similar acidity. Fresh chervil is traditional but hard to find—skip it or use a bit of fresh parsley. For the butter, European-style unsalted has higher fat content, which helps the emulsion. If you’re worried about raw eggs, pasteurized eggs are a safe alternative.

This sauce is best served immediately but can be held in a thermos for up to 1 hour. Leftover Béarnaise can be refrigerated for 2 days (reheat gently in a double boiler). Do not microwave—it will break the emulsion. The clarified butter can be made a day ahead and stored in the fridge.

Step-by-Step Instructions for Knorr Béarnaise Sauce

Master this classic French technique with precise timing and temperature control for perfect results.

Step 1: Reduce the Shallot and Herb Infusion

Combine the 0.25 cup White Wine Vinegar, 0.25 cup White Wine, 2 tbsp Shallots, 2 tbsp Fresh Tarragon, 1 tbsp Fresh Chervil, and 1 tsp Black Peppercorns in a small saucepan. Bring to a gentle simmer over medium heat.

Reduce the mixture until the liquid has decreased by half, about 3-4 minutes. You want a concentrated, aromatic base with visible steam rising and the shallots softened. Strain the mixture through a fine-mesh sieve, pressing on the solids to extract maximum flavor, then discard the solids.

Step 2: Clarify the Butter

Melt the 1 cup Unsalted Butter in a separate small saucepan over low heat. As the butter melts, the milk solids will separate and settle to the bottom. Skim off any foam that rises to the surface with a spoon.

Continue heating until the butter is completely melted and the liquid is clear with milk solids settled at the bottom—about 5 minutes. Carefully pour the clarified butter into a measuring cup, leaving the milk solids behind. This ensures a smooth, stable emulsion in your final sauce.

Step 3: Temper the Egg Yolks

In a heatproof bowl, whisk the 3 whole Egg Yolks with the 0.25 tsp Salt and 1 tsp Lemon Juice until pale and slightly thickened, about 1 minute. Place the bowl over a pot of barely simmering water, ensuring the bottom doesn’t touch the water.

Slowly drizzle in the strained vinegar reduction while whisking constantly. Continue whisking over the double boiler for 2-3 minutes until the mixture thickens enough to coat the back of a spoon. The mixture should be pale yellow and slightly ribbony.

Step 4: Emulsify with Clarified Butter

Remove the bowl from heat and begin whisking in the clarified butter very slowly, a few drops at a time at first, then in a thin, steady stream. This gradual addition is crucial for a stable emulsion. The sauce will begin to thicken and take on a creamy, pale yellow appearance.

If the sauce becomes too thick, whisk in a teaspoon of warm water to loosen it. Continue adding the butter until fully incorporated, about 3-4 minutes total. The finished sauce should be thick but pourable, with a smooth, glossy texture.

Step 5: Adjust and Serve Immediately

Taste the sauce and adjust seasoning if needed. If it’s too thick, whisk in a small amount of warm water. If it’s too thin, briefly return the bowl to the double boiler and whisk for another 30 seconds.

Serve the béarnaise immediately over grilled meats, fish, or vegetables. The sauce will hold in a warm spot for up to 1 hour, but it’s best enjoyed fresh while the emulsion is at its peak. Stir occasionally to maintain consistency.

Wine and Beer Pairings for This knorr bearnaise sauce

White Wine Pairings

A crisp Sauvignon Blanc from Loire Valley mirrors the sauce’s tarragon notes beautifully. The bright acidity cuts through the rich butter base, creating a perfect balance on your palate. 🍷

Red Wine Options

For red lovers, a light Pinot Noir from Burgundy complements without overpowering. Its earthy undertones harmonize with the shallots and herbs in the sauce. Serve slightly chilled at 60-65°F.

Beer Pairings

A Belgian Saison with its peppery notes and dry finish pairs wonderfully. The effervescence cleanses your palate between bites. I love Saison Dupont with this sauce over grilled steak. 🍺

Champagne Sparkle

Brut Champagne or Prosecco adds a celebratory touch. The bubbles contrast the creamy texture while the acidity balances the richness. A 5-ounce pour is the perfect portion.

Non-Alcoholic Choice

Sparkling water with a squeeze of lemon works surprisingly well. The carbonation and citrus mimic wine’s palate-cleansing properties. Serve in a wine glass for the full experience.
