⭐ Greek Yogurt (Best Nut-Free Option)
1 cup Greek yogurt per 1 cup sour creamGreek yogurt has a thick, creamy texture and a tangy flavor profile similar to sour cream, making it an excellent substitute in cream sauces. The protein content helps maintain sauce stability during gentle heating.
To avoid curdling, add Greek yogurt off the heat or temper it by gradually mixing some warm sauce into the yogurt before combining fully. Avoid boiling the sauce after adding yogurt.
The final sauce will be slightly less rich but equally creamy and tangy, with a subtle difference in flavor that is generally well accepted.
