Greek Yogurt (Best Option)
1:1 (1 cup Greek yogurt per 1 cup heavy cream)Greek yogurt works well because it has a thick, creamy consistency and a moderate fat content that mimics heavy cream’s mouthfeel. Its protein content helps stabilize emulsions, which is essential for salad dressings.
To ensure the dressing isn’t too thick, you can thin Greek yogurt slightly with a small amount of water or lemon juice. Avoid overheating as yogurt can curdle.
The final dressing will be tangier and thicker than with heavy cream, adding a fresh flavor dimension while maintaining creaminess.
