Bring your sirloin to room temperature 30 minutes before cooking.
Preheat your air fryer to 350ºF (177ºC).
Prepare pork spice blend. Combine the olive oil, garlic powder, smoked paprika, Italian seasoning, salt, and black pepper in a small bowl.
Season the pork sirloin. Pat the pork sirloin roast dry with paper towels. This will help achieve that delightful crispy texture. Then, rub the delightful spice blend all over the pork sirloin roast.
Air fry pork sirloin roast. Place the pork in the air fryer, ensuring it doesn't touch the sides to ensure even cooking. Air fry at 350ºF (177ºC) for 45 - 60 minutes, flipping the roast halfway through. This technique guarantees a beautifully golden crust and succulent interior.
Check for doneness. Use an instant-read thermometer to check the internal temperature. Make sure the pork reaches 145ºF (63ºC) for safe consumption.
Rest and slice the meat. Once it reaches the safe temperature, remove the pork sirloin roast from the air fryer and let it rest for 5 - 10 minutes. This step allows the juices to evenly distribute. Now, go ahead and slice the roast into your desired portions.
Serve and enjoy your air fried pork sirloin roast. Pair it with your favorite sides, such as roasted vegetables, creamy mashed potatoes, or a refreshing salad. These pairings will complement the flavors impeccably.
