Rinse and chop the serrano peppers finely.
In a mixing bowl combine Greek yogurt, all-purpose flour, baking powder, chopped serrano peppers, and salt and stir until they are fully combined together.
Knead the dough using your hands to form a ball of dough. When it's finished, the dough shouldn't be sticky and should be smooth.
Once this is done you will want to place the dough on a surface drizzled with all purpose flour (I used a cutting board). Shape the dough into a ball and cut into 4 equal pieces. Flour your finger and poke a hole through each dough ball. Stretch the center of the hole and create a bagel shape. If it's sticky sprinkle a little bit of flour. Repeat for all the dough balls.
Meanwhile, grease your air fryer basket with oil. I grease mine by brushing oil generously on the bottom grate. Furthermore, follow your air fryer directions for preheating to 290°F for 5 minutes.
Once the bagels are put together, using a pastry brush, brush the top of the bagels with a lightly beaten egg. Further top the bagels with your favorite toppings. I have used sesame seeds.
When it’s preheated, place the bagels in a single layer. Set the time and temperature at 290°F for 15 to 18 minutes. Make sure they are separated out or else they will stick to each other when ready. Every air fryer is different, check the bagel after the 15-minute mark and add or reduce the timing according to your fryer. Finally, let the bagels cool before cutting them. Enjoy
