Cooking pork knuckle in an air fryer is a great way to achieve a crispy, tender, and flavourful result without the need for deep-frying. This method also reduces the amount of oil and calories in the dish. The process involves simmering the pork knuckle with spices and seasonings until tender, then draining and air-frying it. The cooking time can vary depending on the desired level of crispness and the specific air fryer being used, but it typically ranges from 20 minutes to 60 minutes at temperatures between 180°C and 450°F.

What You'll Learn
Pre-boiling and seasoning the pork knuckle
To prepare your pork knuckle for air frying, start by pricking the skin with multiple small pinprick holes. This will prevent the skin from bursting during cooking by allowing steam to escape. Next, place the pork knuckle in a large pot and cover it with water. Add seasonings and spices to the water, such as garlic, bay leaves, peppercorns, and a heavy amount of salt. Bring the water to a boil and then lower the heat to simmer until the meat is very tender. The simmering time will depend on the size of the knuckle and the age of the pig, but it can range from one and a half hours to three hours.
After simmering, remove the pork knuckle from the pot and place it on a rack to rest and cool. You can chill the boiled pork in the refrigerator, but it is not necessary to air-dry it before air frying. Once the meat has cooled, the skin should be dry. At this point, you can also pierce the skin again and brush it with a vinegar and salt solution, allowing it to dry overnight in the fridge for crispier skin.
When you're ready to air fry, simply place the pork knuckle in the air fryer basket and cook at the desired temperature and time, typically between 180-200°C for 20-40 minutes, depending on your air fryer model and desired level of doneness. For crispier skin, consider air frying at a higher temperature for a shorter amount of time.

Air fryer temperature and time
The temperature and time for cooking pork knuckle in an air fryer depend on the weight of the knuckle and the wattage of the air fryer. It's recommended to preheat the air fryer to around 350°F (175°C).
For a 500g knuckle, one source recommends cutting the time to 2.5 hours with 30 minutes on higher heat. Another source recommends cooking a 500g knuckle at 180°C for 25 minutes.
For a larger knuckle, one source recommends preheating the air fryer to 400°F and cooking for 40 minutes. Another source recommends preheating to 450°F and cooking for 15 minutes, then reducing the temperature to 350°F and cooking for an additional 10 minutes.
It's important to note that the cooking time may vary depending on the desired level of doneness. For a knuckle that falls off the bone, the internal temperature should reach at least 190°F. For an even more tender knuckle, the internal temperature should reach 202°F.
Additionally, the air fryer's wattage can affect the cooking time. For example, one source with a 2150W air fryer recommends cooking at 180°C for 60 minutes, turning the knuckle once.
Before air frying, it's essential to prepare the pork knuckle properly. This includes pricking the skin with multiple small holes to prevent the skin from bursting during cooking. The pork knuckle should also be seasoned or marinated, and some recipes recommend brining it for up to two days before air frying.

Internal temperature of the pork knuckle
The internal temperature of the pork knuckle is an important factor in determining the doneness and tenderness of the meat. When cooking pork knuckle in an air fryer, it is recommended to cook the meat until it reaches an internal temperature of at least 190°F, which ensures that the meat is fully cooked and will fall off the bone. This temperature reading should be taken after the initial cooking time of around 50 minutes, as per the recipe instructions.
To achieve this internal temperature, it is advisable to use a meat thermometer inserted into the thickest part of the meat, away from the bone. This will provide an accurate reading of the doneness of the pork knuckle. If the desired internal temperature has not been reached, the pork knuckle can be returned to the air fryer for additional cooking time.
For those who prefer their pork knuckle even more tender, it is suggested to cook the meat to a higher internal temperature of 202°F. This extended cooking time will ensure that the meat is extremely tender and practically melts off the bone. The additional cooking time required to reach this temperature will depend on the size of the pork knuckle and the specific air fryer being used.
It is worth noting that the cooking time and temperature settings mentioned in the previous paragraphs may need to be adjusted based on the weight and thickness of the pork knuckle being cooked. A larger or thicker cut of meat will likely require a longer cooking time to reach the desired internal temperature. As such, it is recommended to use a meat thermometer to monitor the internal temperature of the pork knuckle throughout the cooking process.

Air drying the pork knuckle
Air-drying the pork knuckle is an important step in the cooking process. Firstly, you should pierce the skin with multiple small pinprick holes. This will prevent the skin from bursting during cooking as steam will be able to escape. You can then brush the pork knuckle with a vinegar and salt solution. This will help to dry out the skin and give it that crispy texture. You should then leave the pork knuckle to air dry for at least 6 hours. If you are short on time, you can place it in the air fryer for 3 hours to dehydrate. Alternatively, you can leave it to dry overnight in the fridge.
Once the pork knuckle has been air-dried, you can rub it with cooking oil. This will help to ensure that the skin becomes crispy during the air-frying process. You should then place the pork knuckle in the air fryer basket or tray. The air fryer should be preheated to a high temperature, typically between 350°F and 450°F. The cooking time will vary depending on the weight of the pork knuckle and the desired level of crispiness. For a 500g knuckle, 2.5 hours with 30 minutes on a higher heat will be sufficient. For larger knuckles, you may need to cook for up to 50 minutes, or even 60 minutes if your air fryer is powerful.

Reheating the pork knuckle
Preparing the Pork Knuckle for Reheating:
Start by slicing the pork knuckle into smaller, even pieces. This helps the meat reheat more quickly and evenly, preventing overcooking. Place the sliced pork knuckle on a microwave-safe plate.
Sprinkling Water:
Lightly sprinkle some water onto the meat sections of the pork knuckle. Be extremely cautious to avoid getting any water on the skin, as this can impact the crispiness.
Setting Up the Air Fryer:
Set the temperature of the air fryer to 350°F/180°C. This temperature ensures effective reheating without drying out the meat excessively.
Placing the Pork Knuckle in the Air Fryer:
Arrange the sliced pork knuckle in the air fryer basket, ensuring the skin sides face outward. Cover the meat sections with foil to protect them from direct heat, while leaving the skin exposed to achieve crispiness.
Reheating Time:
Place the air fryer basket into the air fryer and heat the pork knuckle for 3 to 4 minutes. Then, use a meat thermometer to check the internal temperature of the thickest part of the meat. The ideal temperature for juicy, thoroughly reheated pork is 165°F/73°C. Depending on your air fryer's performance and the initial temperature of the pork, you may need to adjust the reheating time accordingly.
Crisping the Skin:
If the skin hasn't reached your desired crispiness after the initial reheating, you can try giving it a quick blast of direct heat. Remove the foil and expose the skin to the air fryer's heat for an additional minute or less. Keep a close eye on it to prevent burning.
Serving Suggestions:
Once the pork knuckle has reached the desired temperature and crispiness, remove it from the air fryer and serve immediately. Consider pairing it with sides like wine-braised sauerkraut or mustard potatoes for a delicious meal.
Notes and Tips:
- Be cautious not to overcrowd the air fryer. Allow sufficient space around the meat for proper air circulation. If you have a large quantity of pork knuckle to reheat, consider doing it in batches.
- Avoid getting water on the skin during the reheating process, as this can make the skin soggy and affect its texture.
- Keep in mind that air fryers generate super-heated, dry air, which can quickly dry out the meat if left too long. Monitor the pork knuckle closely during reheating to prevent overcooking.
