Preheat the air fryer to 350 degrees F.

In a medium bowl, whisk together the gluten-free flour, baking powder, and kosher salt.

Add the Greek yogurt and stir until a shaggy dough forms.

Knead the dough in the bowl for 45 seconds until mostly smooth; if sticky, knead in additional flour 1 tablespoon at a time until workable.

Rest the dough for 2 minutes.

Divide dough into 13 pieces, roll each into a short rope, and pinch ends together to form mini rings with slightly large holes.

Sprinkle everything bagel seasoning on top and press gently to adhere.

Arrange bagels in a single layer in the air fryer basket with space between them; cook in batches if needed.

Air fry for 10 minutes until lightly golden and set.

Cool for 3 minutes before slicing and serving.
