Preheat your air fryer to 370ºF (187ºC) for 5 minutes.
Prepare the smoky rub. In a small bowl, combine the avocado oil and liquid smoke. Mix the paprika, garlic powder, onion powder, salt, and black pepper in another bowl.
Season the ribs. Rub the smoky oil mixture evenly over the country style ribs, ensuring they're well-coated. Then, sprinkle and massage the dry seasoning mixture over the ribs, ensuring they’re evenly seasoned.
Air fry country style ribs. Place the boneless ribs in the air fryer, arranged in a single layer. If your air fryer is small, you may need to cook the ribs in batches. Air fry the ribs at 370ºF (187ºC) for 20 - 25 minutes, flipping them halfway through.
After 20 - 25 minutes, glaze with barbecue sauce. Brush a generous layer of barbecue sauce onto both sides of the ribs. Make sure to coat them evenly.
Continue air frying. Air fry for another 5 - 7 minutes at 400ºF (204ºC). This will caramelize the sauce and create a deliciously sticky glaze.
Check for optimal tenderness. Ensure the internal temperature of the boneless ribs reaches between 195ºF and 205ºF (90ºC - 96ºC) using a meat thermometer. This will guarantee the most tender and flavorful country style ribs.
Serve and enjoy. Once done, remove the ribs from the air fryer and rest for 5 - 10 minutes. Then, serve your succulent air fried country style ribs with your favorite sides and savor the amazing flavors!
