⭐ Sour Cream (Best Nut-Free Option)
1:1 (replace Greek yogurt volume for volume)Sour cream works well because it has a similar fat content and acidity level as Greek yogurt, which helps activate the gluten network in the dough and contributes to the characteristic chewiness of bagels. The acidity also enhances yeast activity and flavor development.
For best results, use full-fat sour cream and ensure it is well incorporated into the dough to maintain consistent hydration. Avoid low-fat or non-fat versions as they can alter texture and moisture balance.
Compared to Greek yogurt, sour cream may produce a slightly richer flavor but will not significantly change the texture or rise of the bagels, making it an excellent direct substitute.
