In a large bowl, add egg and whisk. Add cottage cheese and whisk again to combine.
Add flour, baking powder, baking soda, and salt and mix again to combine.
Add cheese and chives and mix again until combined. It may be easier to mix with your hands at this point as the dough will be very thick.
Sprinkle a little flour onto a clean counter or cutting board. Shape the dough into a ball and roll it out until it is about 1 inch thick. Slice into thirds both ways to create 9 biscuits.
Line air fryer basket with parchment paper and spray with oil spray.
Add biscuits to the air fryer and space them about 1 inch apart if possible. Spray the tops of the biscuits with oil spray.
Air fry at 350F for 10 minutes until golden brown on top and puffed up. Flip biscuits and air fry for 2 more minutes.
