⭐ Greek Yogurt (Best Gluten-Free Option)
1/4 cup Greek yogurt per 1/4 cup sour creamGreek yogurt works well because it has a thick, creamy texture and a tangy flavor profile similar to sour cream, which helps maintain the moisture and acidity balance in the frittata. The lactic acid in Greek yogurt aids in tenderizing the eggs and enhancing flavor complexity.
For best results, use full-fat Greek yogurt to replicate the richness of sour cream. Avoid using low-fat versions as they can make the frittata slightly drier. Stir gently to incorporate without overmixing to preserve the airy texture.
Compared to sour cream, Greek yogurt yields a slightly tangier and denser frittata, but the difference is subtle and generally well-received.
