⭐ Greek Yogurt (Best Gluten-Free Option)
1:1 (1/4 cup Greek yogurt per 1/4 cup sour cream)Greek yogurt contains live cultures that provide a tangy flavor similar to sour cream, and its thick, creamy texture closely replicates sour cream’s mouthfeel. The protein content helps it maintain stability when mixed into hot dishes like chili.
To prevent curdling, stir the yogurt in at the end of cooking and avoid boiling the chili after adding it. Using full-fat Greek yogurt ensures a richer texture and better flavor balance.
Compared to sour cream, Greek yogurt may be slightly less rich but offers a comparable tang and creaminess, making it the most seamless substitute in chili.
