Add the flour and yogurt to a large mixing bowl and mix until a thick dough forms. Add more yogurt if needed.

Dust a surface with flour and knead the dough for a few minutes, forming it into a ball. Let it sit at room temperature for up to 10 minutes.

Cut the dough into four sections, roll each into a ball, and poke a thumb hole in the center to form bagels.

Line a baking sheet with parchment paper and place the bagels on the sheet. Brush with egg wash and sprinkle with seasoning if desired.

Bake at 350°F (177°C) for 22-24 minutes. Gluten-free bagels may require an additional 5 minutes.

Let bagels cool for 5 minutes on a wire rack before serving.
