Greek Yogurt (Best Option)
1:1 (1 cup Greek yogurt per 1 cup cream cheese)Greek yogurt works well because it has a similar protein and fat content to cream cheese, which helps emulsify the marinade and tenderize proteins through its acidity. The lactic acid in Greek yogurt breaks down muscle fibers, enhancing tenderness.
For best results, use full-fat Greek yogurt and strain it if too watery to achieve a consistency closer to cream cheese. Avoid over-marinating as the yogurt's acidity can make proteins mushy.
Compared to cream cheese, Greek yogurt yields a lighter marinade with a tangier taste and slightly less richness, which can brighten the flavor profile without sacrificing texture.
