Add the garlic cloves, aquafaba, lemon juice, and salt to a blender or food processor.

Blend the ingredients until the sauce is mostly smooth.

With the blender/processor motor running, slowly drizzle the oil into the blender or food processor until the sauce is smooth, glossy, and emulsified.

Taste the dressing and blend in more salt, lemon juice, or garlic as needed. Transfer finished sauce to an airtight container or enjoy it right away.
