Ingredients for Knorr Bearnaise Sauce

Classic French flavors with minimal effort and accessible ingredients for home cooks.

The butter is critical—use high-quality unsalted from a trusted brand like Land O’Lakes or Kerrygold. Clarifying it removes milk solids that could cause separation. The egg yolks should be fresh, room temperature for maximum emulsification. Whole Foods or Trader Joe’s carry reliable shallots and fresh herbs. For the wine, any dry white works, but a crisp Sauvignon Blanc adds the right acidity.

No tarragon? Dried tarragon at one-third the amount works in a pinch, though fresh is ideal. Missing chervil? Skip it—the tarragon carries the flavor. For a shortcut, the Knorr package provides the base, but purists may omit it and boost the herbs. White wine vinegar can be swapped for apple cider vinegar, though the flavor profile shifts slightly.

Finished sauce keeps 1-2 days in the fridge in an airtight container. Do not freeze—it will separate. For best results, use immediately. If it breaks, whisk in 1 tsp hot water to re-emulsify. Always discard if left at room temperature for more than 2 hours.

Step-by-Step Instructions for Knorr Bearnaise Sauce

This refined technique preserves the classic French character while keeping preparation straightforward.

Step 1: Clarify the Butter

Melt the 0.5 cup Unsalted Butter in a small saucepan over medium heat. As it melts, the milk solids will separate and sink to the bottom. Continue heating for 3-4 minutes until the liquid turns clear and the milk solids are golden brown.

Carefully pour the clarified butter through a fine-mesh strainer into a heatproof bowl, leaving the milk solids behind. This step is essential for a smooth, stable sauce. Set the clarified butter aside in a warm place—it should remain liquid but not hot when you add it later.

Step 2: Reduce the Aromatics

In a small saucepan, combine the 2 tbsp White Wine Vinegar, 2 tbsp Shallots, 2 tbsp Dry White Wine, 1 tbsp Fresh Tarragon, 1 tsp Fresh Chervil, 0.25 tsp Salt, and 0.125 tsp White Pepper. Bring to a gentle simmer over medium heat.

Cook for 4-5 minutes until the liquid reduces by half and the shallots are nearly translucent. The mixture should be fragrant and slightly syrupy. Remove from heat and let cool for 2 minutes—adding hot liquid to egg yolks would scramble them.

Step 3: Whisk the Egg Yolks and Sauce Mix

In a heatproof bowl, whisk together the 3 whole Egg Yolks and the 1 package Knorr Bearnaise Sauce Mix until smooth and slightly thickened. The mixture should have no lumps and a pale, creamy appearance.

Place the bowl over a pot of barely simmering water, ensuring the bottom doesn’t touch the water. Whisk constantly for 1-2 minutes until the mixture lightens in color and begins to thicken. This gentle heat tempers the eggs, creating a stable base for the sauce.

Step 4: Emulsify with Clarified Butter

Slowly drizzle the warm clarified butter into the egg mixture, whisking constantly. Start with a thin stream, then increase to a steady pour as the sauce begins to emulsify. This process should take 3-4 minutes—rushing it risks breaking the emulsion.

Continue whisking until all the butter is incorporated and the sauce is thick enough to coat the back of a spoon. If it becomes too thick, whisk in a splash of warm water to adjust the consistency. The sauce should be smooth, creamy, and pale yellow.

Step 5: Finish and Serve

Remove the sauce from the heat and stir in any remaining fresh herbs if desired. Taste and adjust seasoning with additional salt or white pepper as needed. Bearnaise sauce is best served immediately while still warm.

Keep the sauce warm in a thermos or a bowl set over warm water if not serving right away. If it thickens too much upon standing, whisk in a small amount of warm water to restore the creamy texture. This sauce pairs beautifully with grilled steaks, fish, or vegetables.

Essential Equipment for Great knorr bearnaise sauce

Double Boiler Setup

I always use a heatproof glass or stainless steel bowl that fits snugly over a saucepan. The bowl should not touch the water—keep it 1-2 inches above simmering water. I recommend All-Clad stainless steel for even heat distribution and durability. 💡

Whisk Selection

A balloon whisk with a comfortable grip is essential for constant motion. I prefer OXO Good Grips for its ergonomic handle. Avoid silicone whisks—they don’t provide enough control for emulsifying this delicate sauce.

Fine-Mesh Strainer

For clarifying butter, a fine-mesh strainer catches all milk solids. I use Cuisinox—it’s sturdy and fine enough to strain even small particles. This ensures your sauce stays smooth and stable without any risk of separation.

Small Saucepan

Use a 1-2 quart saucepan for reducing aromatics—too large and the liquid evaporates too quickly. I swear by Le Creuset enamel-coated cast iron for even heating. The light color lets you monitor the reduction process easily.

Thermometer

A candy or instant-read thermometer helps monitor butter temperature. Keep clarified butter between 160-180°F when adding to eggs. I use ThermoWorks for precision. Never let the butter get too hot or it will scramble the yolks.

Serving Tools

For serving, a small gravy boat or squeeze bottle keeps the sauce warm. I love OXO’s angled gravy separator for elegant presentation. Keep a warm water bath nearby to maintain the perfect consistency. 🔥
