⭐ Whole Soy Milk (Best Vegan Option)

1:1 substitution (1 cup whole soy milk per 1 cup whole milk)

Quick tip: Offers a similar protein and fat content to whole milk, but may impart a slight bean-like flavor.

Whole soy milk contains comparable protein and fat levels to whole milk, which supports the emulsification process in Hollandaise sauce. The proteins help stabilize the mixture, while the fat adds creaminess.

To use soy milk successfully, ensure it is unsweetened and unflavored. Heat gently and whisk continuously to avoid separation. Soy milk can sometimes cause a slight beany aftertaste.

The sauce will be slightly less rich and may have a subtle flavor difference, but the texture and stability remain acceptable.

Oat Milk (Barista Blend)

1:1 substitution (1 cup oat milk per 1 cup whole milk)

Quick tip: Barista blends have added fats and stabilizers to mimic dairy creaminess, improving sauce texture.

Oat milk barista blends are formulated with added oils and emulsifiers to better replicate the mouthfeel and fat content of dairy milk. This makes them more suitable for emulsified sauces like Hollandaise.

Use at room temperature and whisk steadily to maintain emulsion. Avoid flavored or sweetened versions as they can alter the sauce's taste.

The final sauce will be slightly less rich than with dairy milk but still creamy and stable, with a mild oat flavor that is generally unobtrusive.
