⭐ Greek Yogurt (Best Gluten-Free Option)
1:1 (1/4 cup Greek yogurt per 1/4 cup sour cream)Greek yogurt works well because it has a similar acidity and creamy consistency to sour cream, which helps tenderize the meat and adds moisture. The lactic acid in Greek yogurt also aids in protein breakdown, contributing to a tender meatloaf.
For best results, use full-fat Greek yogurt to replicate the fat content of sour cream, which helps maintain moisture and richness. Avoid overmixing to prevent the yogurt from breaking down and releasing too much liquid.
Compared to sour cream, Greek yogurt may impart a slightly tangier flavor and a denser texture, but it generally enhances the meatloaf's moistness and binding without overpowering the other ingredients.
