⭐ Greek Yogurt (Best Gluten-Free Option)
1:1 (1 cup Greek yogurt per 1 cup sour cream)Greek yogurt works well because it has a similar protein and fat content to sour cream, which helps maintain the dough's elasticity and moisture balance. Its natural acidity also contributes to the flavor profile typical of bagels.
For best results, use full-fat plain Greek yogurt and avoid varieties with added flavors or sweeteners. If the yogurt is too thick, slightly thin it with a teaspoon of milk or water to match sour cream's consistency.
Compared to sour cream, Greek yogurt produces bagels with a slightly tangier taste and a similarly tender crumb, preserving the characteristic chewiness and moisture.
