Greek Yogurt (Best Option)
1:1 (1 cup Greek yogurt per 1 cup sour cream)Greek yogurt contains live cultures that provide the necessary acidity to tenderize the chicken and replicate the tangy flavor of sour cream. Its thick consistency helps the breading stick effectively, creating a crispy crust upon frying.
To ensure success, use full-fat Greek yogurt for optimal moisture and richness. Avoid overly watery or low-fat versions as they may thin the batter and reduce crispiness.
Compared to sour cream, Greek yogurt yields a slightly tangier flavor and a similarly tender texture, making it the closest and most reliable substitute in fried chicken recipes.
