Ingredients for air fryer pork knuckle
A few quality ingredients transform pork knuckle into a crispy, tender centerpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Knuckle 🍖 | 2 lb | Bone-in, skin-on for crispiness |
| Coarse Sea Salt 🧂 | 2 tbsp | For dry-brining the skin |
| Black Pepper 🌶️ | 1 tbsp | Freshly ground preferred |
| Garlic Powder 🧄 | 1 tbsp | Or 3 fresh cloves minced |
| Onion Powder 🧅 | 1 tbsp | For depth of flavor |
| Smoked Paprika 🌶️ | 1 tsp | Adds authentic BBQ flavor |
| Dried Thyme 🌿 | 1 tsp | Complements pork well |
| Olive Oil 🫒 | 1 tbsp | For rubbing the skin |
| Apple Cider Vinegar 💧 | 1 tbsp | Balances richness of pork |
| Brown Sugar 🍚 | 1 tbsp | Optional for caramelization |
| Beer 🍺 | ½ cup | Light lager for steaming |
| Chicken Stock 🥣 | ½ cup | For basting liquid |
The pork knuckle is critical—look for bone-in, skin-on cuts at a quality butcher or Whole Foods. Skin thickness of at least 1/4 inch ensures proper crackling. Avoid pre-brined or enhanced pork, as the skin won't crisp as well. I source mine from local farms when possible, but Costco also carries excellent options in bulk for larger gatherings.
No smoked paprika? Regular paprika plus a pinch of cayenne works. Beer can be substituted with apple juice or water, though the flavor will be milder. Fresh garlic and onion can replace the powders—use 3 cloves minced and 1 small onion grated. The brown sugar is optional but adds a nice caramelized finish to the skin.
Pork knuckle can be dry-brined overnight for maximum flavor penetration. Once cooked, it keeps in the fridge for 3-4 days or can be frozen for up to 3 months. Reheat in the air fryer at 350°F for 8-10 minutes to restore crispiness.

Step-by-step instructions for air fryer pork knuckle
This method guarantees crispy skin and fall-off-the-bone meat with minimal effort.
Score and Dry-Brine the Pork Knuckle
Pat the 2 lb Pork Knuckle completely dry with paper towels, focusing on the skin. Using a sharp knife, score the skin in a crosshatch pattern, cutting through the skin and fat but not into the meat. This allows the fat to render out and the skin to crisp up beautifully.
Rub the 2 tbsp Coarse Sea Salt and 1 tbsp Black Pepper all over the pork knuckle, pressing it into the scored skin and the meat. This dry-brine step ensures the skin crisps while keeping the meat juicy. Let it sit uncovered in the refrigerator for 12-24 hours for best results.
Apply the Flavor Rub
Combine the 1 tbsp Garlic Powder, 1 tbsp Onion Powder, 1 tsp Smoked Paprika, and 1 tsp Dried Thyme in a small bowl. Rub this mixture evenly over the entire surface of the pork knuckle, ensuring it gets into all the crevices and scored lines.
In a separate bowl, mix the 1 tbsp Olive Oil, 1 tbsp Apple Cider Vinegar, and 1 tbsp Brown Sugar. Brush this mixture over the skin, which will help with caramelization and add a subtle tangy sweetness to balance the richness of the pork.
Air Fry to Crispy Perfection
Preheat your air fryer to 375°F. Place the pork knuckle skin-side up in the air fryer basket, ensuring it fits without touching the sides. Air fry for 40 minutes at 375°F.
After 40 minutes, carefully flip the pork knuckle and cook for another 30 minutes. Then, flip it back skin-side up and increase the temperature to 400°F. Cook for an additional 10-15 minutes, basting the skin with a mix of 0.5 cup Beer and 0.5 cup Chicken Stock every 5 minutes until the skin is deep golden brown and crispy.
Rest and Serve
Remove the pork knuckle from the air fryer and let it rest for 10-15 minutes before carving. This resting period allows the juices to redistribute, ensuring the meat stays moist and tender.
The skin should be crackling crisp, and the meat should pull away from the bone easily. Serve with your favorite sides, and enjoy the perfect combination of crispy and tender textures.
Pro Tips For Making Air Fryer Pork Knuckle
- Preheat the Air Fryer: Sounds basic, but I learned this the hard way—cold starts give you uneven crispiness. 400°F for 5 minutes before adding the pork knuckle makes all the difference for that crackling skin.
- Score the Skin Deep: Use a sharp knife to cut 1/4-inch slashes in the fat cap before seasoning. After burning one batch, I finally figured out shallow scores don’t let the fat render properly.
- Skip the Overcrowding: Resist the urge to cram it in. The pork knuckle needs space for hot air to circulate, or you’ll end up steaming it instead of crisping.
- Double Season the Meat: Rub the coarse sea salt, black pepper, garlic powder, and onion powder into the scored skin and the meat underneath. My grandmother swore by this, and she was right: it builds layers of flavor.
Storing and reheating this recipe
Refrigerator Storage
Let your pork knuckle cool completely, then wrap it tightly in aluminum foil or place it in an airtight container. It keeps in the fridge for 3-4 days without losing moisture. I always store mine with a paper towel to absorb any excess grease. ❄️
Freezer Storage
For longer storage, wrap the cooled pork knuckle in plastic wrap, then foil, or use a freezer-safe bag. It stays fresh for up to 3 months. Squeeze out all air to prevent freezer burn. I label mine with the date to track freshness.
Air Fryer Reheating
To revive that perfect crackling, preheat the air fryer to 375°F and reheat for 8-10 minutes. Baste with a little beer or chicken stock halfway through to restore moisture. The skin will crisp up almost like fresh. 🔥
Oven Reheating
Preheat your oven to 350°F and place the pork knuckle on a wire rack over a baking sheet. Cover loosely with foil and heat for 15-20 minutes, then uncover and broil for 2-3 minutes to crisp the skin.
Microwave Option
For a quick fix, microwave covered with a damp paper towel on 50% power for 2-3 minutes. Finish in a hot skillet for 1-2 minutes per side to restore some crispiness. Not ideal, but it works in a pinch.

Frequently asked questions
Can I use a bone-in pork shoulder instead?
While you can, pork knuckle has thicker skin that crisps better. Shoulder will work but may not achieve the same crackling texture. Adjust cooking time to 45-50 minutes at 375°F for shoulder.
Why is scoring the skin important?
Scoring allows fat to render out and helps the skin crisp evenly. Without scoring, the skin may stay chewy instead of becoming crackling crisp. Use a sharp knife for clean cuts.
How do I know when it's done?
The skin should be deep golden and crack when pressed. Internal temperature should reach 160°F in the thickest part. The meat will pull away from the bone easily when fully cooked.
Can I skip the dry-brine step?
Skipping dry-brining may result in less crispy skin. If short on time, at least pat the skin very dry and salt it heavily before cooking. The overnight step is ideal for maximum crispiness.
