⭐ Greek Yogurt (Best Nut-Free Option)
1:1 (1 tablespoon Greek yogurt per 1 tablespoon sour cream)Greek yogurt works well because it has a similar protein structure and acidity level to sour cream, which helps maintain the sauce’s balance of flavors and texture. The live cultures in yogurt contribute to the tanginess that complements the sweet and savory elements of teriyaki sauce.
For best results, use full-fat Greek yogurt to preserve richness and avoid curdling by adding it towards the end of cooking or off heat. Stir gently to maintain smoothness.
Compared to sour cream, Greek yogurt may be slightly less rich but offers a fresh tang that enhances the sauce without overpowering it, keeping the traditional teriyaki flavor profile intact.
