Prepare the ribs. Flip the rack of spare ribs over so the bone side is facing up. Use a butter knife or your fingers to gently lift the thin membrane. Use a paper towel to grip and remove the membrane from the back of the ribs. This step is essential for optimal seasoning adherence.
Cut the ribs into 2 to 4 pieces based on your air fryer's size.
Preheat your air fryer to 380ºF (193ºC) for 5 minutes.
Create a rib rub seasoning blend. Combine the brown sugar, smoked paprika, garlic powder, onion powder, cayenne pepper, and dried thyme in a small bowl.
Season pork ribs. Sprinkle the dry rub mixture evenly over both sides of the rib pieces. Gently press the rub onto the meat for an even coating.
Air fry spare ribs. Place the seasoned rib pieces in a single layer in the air fryer. Cook at 380ºF (193ºC) for 30 - 40 minutes, flipping halfway.
Brush with BBQ sauce. About 10 minutes before the ribs are done, brush a layer of barbecue sauce on both sides. This step adds a final burst of tantalizing flavor and a sumptuous glaze.
Check for doneness. Confirm the ribs reach an internal temperature of 145ºF (63ºC) using a meat thermometer. Extend the cooking time by 5 - 10 minutes for even more tenderness if desired.
Once cooked, remove and let the spare ribs rest at room temperature for 5 minutes. This ensures the juices redistribute, creating a succulent and satisfying eating experience.
Serve & enjoy your air fried spare ribs and relish in a hassle-free and delicious meal.
