Is Arrowroot Starch Slurry a good fat-free substitute for Egg in Béarnaise Sauce?

Yes. Arrowroot thickens the sauce but does not emulsify, resulting in a Béarnaise that lacks richness and can separate easily. Use a ratio of 1 teaspoon arrowroot starch mixed with 2 tablespoons water per 1 egg yolk.

⭐ Aquafaba (Best Fat-Free Option)

3 tablespoons aquafaba per 1 egg yolk

Quick tip: Aquafaba provides a light, stable emulsion similar to egg yolk, preserving the sauce’s creamy texture without altering flavor significantly.

Aquafaba, the liquid from cooked chickpeas, contains proteins and starches that act as emulsifiers and stabilizers, closely replicating the egg yolk’s role in Béarnaise sauce. Its ability to trap air and bind fat makes it an excellent substitute in emulsified sauces.

For best results, use aquafaba at room temperature and whisk vigorously to achieve a stable emulsion. It’s important to monitor the sauce closely as aquafaba can be less heat stable than egg yolks, so gentle heating is advised.

Compared to traditional egg yolks, aquafaba produces a slightly lighter texture and a very mild legume note, which is usually masked by the herbs and vinegar in Béarnaise, maintaining the overall flavor profile effectively.

Arrowroot Starch Slurry

1 teaspoon arrowroot starch mixed with 2 tablespoons water per 1 egg yolk

Quick tip: Arrowroot thickens the sauce but does not emulsify, resulting in a Béarnaise that lacks richness and can separate easily.

Arrowroot starch acts as a thickening agent by gelatinizing when heated, which can help mimic the viscosity of Béarnaise sauce. However, it does not provide emulsifying properties, so the fat and acid components may separate.

Add the slurry slowly while whisking and avoid overheating to prevent a slimy texture.

The final sauce will be thicker but lack the smooth, creamy mouthfeel and stability of an egg-based Béarnaise, making it a less ideal substitute.
