In a bowl, combine the shredded chicken, mayo, sour cream, shredded cheese, jalapenos, cilantro, taco seasoning, salt and pepper.
Lay out the tortillas and divide the chicken filling evenly among them. Spread the mixture over each tortilla and then tightly roll it up, with the seam facing down. (You can use toothpicks to secure them and prevent them from unrolling.)
Repeat with all the tortillas- you should get 8-10 small taquitos.
Spray the air fryer basket with cooking spray and add the rolled taquitos in. (Depending on the size of your air fryer, you may need to cook in batches, do not overcrowd the basket.)
Air fry at 400°F for 8-10 minutes, until the filling is melty and the tortillas are golden and crispy. (For extra crunch, flip halfway through the cooking time.)
Top with your favorite toppings and serve immediately.
