⭐ Sour Cream (Best Nut-Free Option)
1:1 (replace Greek yogurt with equal volume of sour cream)Sour cream has a comparable fat content and acidity level to Greek yogurt, which helps to tenderize the meat and add moisture. The lactic acid in sour cream also aids in protein breakdown, contributing to a softer texture.
For best results, use full-fat sour cream to match the richness of Greek yogurt. Avoid low-fat versions as they may not provide enough moisture. Stir it gently into the meat mixture to ensure even distribution.
The final meatloaf will have a slightly richer flavor but remain moist and tender, closely resembling the texture and taste achieved with Greek yogurt.
