Preheat the oven to 350°F (175°C). Line a large rimmed baking sheet with parchment paper.

Add the flour and yogurt to a large bowl. Stir with a spatula just until incorporated and a slightly sticky dough forms. Use your hands to fully bring the dough together if needed. If the dough is too sticky, add 1 tablespoon of flour at a time until smooth and workable.

Form the dough into a thick, round disc, then divide it evenly into 9 pieces. Roll each piece into a ball and place it on the prepared baking sheet, spacing the rolls about 2 inches apart. Brush the tops with egg wash if desired. Bake for about 25 minutes or until golden brown.
