Air fryer technique tips: pat the pork belly very dry so it crispies fast, and preheat your air fryer for best browning. Use a [digital meat thermometer](https://rocktopgear.com/amazon) to confirm the pork reaches at least 145 degrees Fahrenheit, then rest 3 minutes before serving, per USDA guidance. A light mist from a [quality olive oil sprayer](https://rocktopgear.com/amazon) helps the sprouts blister without excess oil. A raised rack, shake tray, or other keto air fryer accessories can improve airflow for extra crunch.
