⭐ Garlic-infused olive oil (Best Dairy-Free Option)
1 teaspoon per 1 tablespoon fresh garlicGarlic-infused olive oil works because it delivers the essential garlic flavor compounds dissolved in fat, which integrates smoothly into the butter-based Béarnaise sauce without introducing fibrous solids that could break the emulsion.
For best results, use a high-quality garlic-infused oil with a mild intensity and add it gradually to maintain the sauce’s balance. Avoid overheating the oil to prevent bitterness.
Compared to fresh garlic, this substitute provides a subtler, more harmonious garlic note that complements the tarragon and shallots without overwhelming the sauce’s delicate texture.
