Crispy pork belly bites cook in 18 minutes at 400 °F (204 °C) with a shake at the 9-minute mark. The high heat is essential — it renders the fat into the basket while crackling the surface in a way no oven can match at home scale. Cube the belly into 1½–2 inch pieces, toss with five-spice and sugar, and expect to clean the drip tray afterwards.

How to tell it’s done

Cubes are deeply golden-brown on every face with crisp crackling edges; fat has rendered visibly into the basket; the cubes have shrunk by about a third.

Internal temperature: 145 °F / 63 °C. Always verify with an instant-read thermometer.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. None — pork belly renders enormous amounts of fat. Toss the cubes with salt, sugar and five-spice for a Cantonese-style dry rub.

2. 2

   Season

   Season with salt, white pepper, Chinese five-spice, brown sugar, garlic powder, soy sauce (light brush, optional).

3. 3

   Load

   Arrange 1 lb pork belly, cut into 1½–2 inch cubes (about 3–4 servings as a starter) for best convection airflow.

4. 4

   Cook

   Set the air fryer to 400 °F (204 °C) and cook for 18 minutes total, shaking once at 9 minutes.

5. 5

   Check & rest

   Verify the internal temperature reaches 145 °F / 63 °C and rest 2–3 minutes before serving.

6. 6

   Store

   Refrigerate up to 4 days. Reheat at 380 °F for 4 minutes to re-crisp the rendered fat edges.

Watch out for

• !Pork belly fat splatters aggressively at 400 °F. Line the drip tray with parchment (NOT paper towels) or a heat-safe air-fryer liner to make cleanup tolerable. Empty the drip tray halfway through — pooled fat can smoke.
• !Score the skin in a tight crosshatch pattern if the cubes have skin attached. The score lines turn into crackling; an unscored skin stays leathery.
• !USDA-safe internal temperature for pork is 145 °F / 63 °C. Visual cues (rendered fat, deeply browned edges) are reliable but a thermometer in the largest cube is the safer call.
• !Do not exceed 400 °F. At 410 °F+ the rendered pork fat smokes heavily and sets off kitchen smoke detectors.

FAQ about pork belly in an air fryer

What temperature should I cook pork belly at in an air fryer?

Cook pork belly at 400 °F (204 °C). The convection air at this temperature browns the exterior quickly without drying the centre.

How long does pork belly take in an air fryer?

Pork belly takes 18 minutes total at 400 °F (204 °C). Shake the basket once at 9 minutes so both sides cook evenly.

Do you need to shake pork belly in an air fryer?

Yes — shake the basket once at 9 minutes. Loose pieces (pork belly) settle into the basket and the bottom layer stays pale unless you redistribute them halfway through.

Do you need to preheat the air fryer for pork belly?

Preheating is optional for pork belly — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.

What internal temperature is pork belly safe to eat?

Pork belly should reach an internal temperature of 145 °F (63 °C) measured at the thickest point with an instant-read thermometer. Visual checks alone are not a reliable substitute for protein — always confirm with a probe.
