Preheat oven to 375°F (190°C) or preheat air fryer to 280°F (140°C).

In a large bowl, combine flour with baking powder and salt. Add Greek yogurt, then quickly stir until it comes to form a dough.

Transfer the protein dough over a clean floured surface and knead to form a soft ball. Divide into 4 equal size pieces.

One at a time, roll each piece of dough into a log about 6 inches (15 cm) in length and shape into a ring.

Optionally, brush the surface of each bagel with egg or egg white wash, then sprinkle your favorite seeds on top.

Transfer the bagels to a parchment paper-lined baking sheet. Bake in hot oven for 20 to 25 minutes, or until the top is golden brown.

Let cool for at least 15 minutes before serving.

For air frying, place 2 to 3 bagels in the basket, leaving enough space between each. Air fry at 280°F (140°C) for 15 to 20 minutes.

Let cool for at least 15 minutes before serving.
