⭐ Greek Yogurt (Best Nut-Free Option)
1/4 cup Greek yogurt per 1/4 cup sour creamGreek yogurt works well because it contains live cultures that provide acidity similar to sour cream, which enhances flavor complexity in stir-fry dishes. Its thick texture mimics sour cream’s creaminess without curdling easily when heated.
To avoid curdling, add Greek yogurt towards the end of cooking and stir gently over low heat. Avoid boiling after adding to preserve texture.
Compared to sour cream, Greek yogurt delivers a slightly more pronounced tang and a firmer texture, which can brighten the dish while maintaining the creamy mouthfeel expected in stir-fry sauces.
