1. Pat the pork loin dry with paper towels to remove any moisture. This step is crucial for a nice crust.

2. If your pork loin has a fat cap, score it lightly with a sharp knife to help render the fat during cooking.

3. In a small bowl, mix together olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper. If using brown sugar and cayenne pepper, add those as well.

4. Rub the seasoning mixture all over the pork loin, ensuring it is evenly coated. This step is key for seasoning pork roast and preparing pork loin for air fryer.

5. Preheat your air fryer to 360°F (182°C). Preheating ensures even cooking from the start.

6. Place the seasoned pork loin in the air fryer basket.

7. Cook at air fryer cooking temperature of 360°F for 25-30 minutes. Turn the pork halfway through the cooking time to ensure even cooking.

8. Use a meat thermometer to check the internal temperature. The pork is done when it reaches 145°F (63°C).

9. If you want a glaze, brush the pork loin with honey in the last 5 minutes of cooking.

10. Remove the pork loin from the air fryer and let it rest on a cutting board for at least 5-10 minutes. Letting pork rest helps retain its juices, making it more tender and flavorful.
