This air fryer roast pork belly recipe delivers the perfect balance of crispy crackling and juicy, melty layers—no oven required. After years of perfecting pork at Atlanta's Smoky Pig, I've adapted this technique for home cooks using just an air fryer.
The secret lies in scoring the fat cap and controlling the temperature to render fat without drying out the meat.
What sets this apart is the two-stage cooking process: first rendering the fat at a lower temperature, then cranking up the heat for that coveted crackling. You'll need just 5 simple ingredients—pork belly, salt, sugar, five-spice powder, and a splash of apple cider vinegar—and about 90 minutes total time.
The vinegar tenderizes while the five-spice adds depth that complements the caramelized exterior.
By the time it's done, you'll have golden-brown crackling that shatters like glass, revealing tender, pink meat underneath. The fat renders perfectly, creating a sauce that pools in the air fryer basket—save this for basting or serving over rice.
This is the kind of pork that makes people ask for seconds before they even sit down.
Serve with apple sauce for dipping or alongside roasted potatoes and braised greens for a complete meal. The air fryer method means less cleanup than traditional roasting while delivering restaurant-quality results. Let's get cooking—your taste buds will thank you.
Ingredients for air fryer roast pork belly
Five ingredients, one air fryer, and the crispy crackling you crave.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🥓 | 2 lb | Skin-on, fat cap intact |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tbsp | Coarse grain preferred |
| Granulated Sugar 🍚 | 1 tbsp | Light brown preferred |
| Five-Spice Powder 🌶️ | 1 ½ tsp | Homemade or store-bought blend |
| Apple Cider Vinegar 🍎 | 1 tbsp | Unfiltered preferred |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For scoring fat cap |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, for garnish |
Pork belly is the star here—look for thick-cut pieces with a good fat cap at Whole Foods or your local butcher. The fat renders beautifully in the air fryer, so don't skimp on marbling. If you can't find a whole piece, Costco sells pre-portioned slabs that work perfectly. Score the fat cap in a crosshatch pattern before cooking—this is non-negotiable for even crackling. For the five-spice, I always reach for Penzeys blend, but any good-quality mix will do. The vinegar tenderizes the meat while adding a subtle tang that balances the richness.
No five-spice powder? Mix 1/2 tsp each cinnamon, cloves, fennel, star anise, and black pepper—it's a game-changer. Running out of apple cider vinegar? Substitute white vinegar or lemon juice, but reduce to 1/2 tbsp to avoid over-acidifying. The sugar helps caramelize the exterior, but if you're watching carbs, reduce to 1 tsp. Fresh rosemary is ideal, but dried works at 1/4 the amount. Pro tip: Score the belly deeper on the fat side—this is where the crackling forms. And trust me, the extra-virgin olive oil makes all the difference when scoring.
This pork reheats beautifully—just pop it back in the air fryer at 350°F for 10-15 minutes. Store leftovers in the fridge for 4 days, wrapped tightly in foil to preserve moisture. The rendered fat solidifies as it cools, so slice through it to serve. For maximum crispiness, serve immediately after cooking. The crackling loses its crunch after 30 minutes, but the meat stays tender for hours. Portion the fat into small containers—it's pure gold for basting or frying eggs later.
Why You'll Love This Recipe
- Fewer Messy Pans: I swear by this method—just salt, sugar, and five-spice rubbed onto the belly, then a quick spray of vinegar before air frying. No basting, no flipping, no oven mitt burns. The air fryer handles all the fuss while I wipe down one counter.
- Crispy Without the Effort: That crackling skin? It’s not from hours in a 250°F oven—just 15 minutes in the air fryer at 375°F, flipping once. The salt-sugar crust locks in juices while giving you that golden, shatterable edge. Honestly, it’s the closest I’ve gotten to fancy restaurant pork belly without the fancy restaurant price tag.

Step-by-step instructions for air fryer roast pork belly
Transforming pork belly into crispy, melt-in-your-mouth perfection takes just a few key techniques.
Score and Season the Pork Belly
Start by scoring the pork belly in a diamond pattern through the fat cap, cutting about ¼-inch deep and 1-inch apart. This creates channels for the fat to render while allowing the skin to crisp evenly. Use a sharp knife and work quickly to avoid tearing the skin.
In a small bowl, mix together the 1.5 tablespoons Diamond Crystal Kosher Salt, 1 tablespoon Granulated Sugar, and 1.5 teaspoons Five-Spice Powder. The sugar helps caramelize the exterior while balancing the salt's intensity. Rub this mixture all over the pork belly, including inside any scored sections, pressing it into the meat so it adheres well. Let it sit uncovered on a wire rack for 30 minutes at room temperature—this ensures even cooking and maximum crispiness.
Score the Fat Cap and Preheat the Air Fryer
Using a sharp knife, score the fat cap in a crosshatch pattern, making cuts about ½-inch apart. This step is crucial—it prevents the fat from pooling in one place and ensures even browning. Be careful not to cut into the meat below. After scoring, use a paper towel to pat the skin completely dry. Any moisture will steam the skin instead of crisping it.
Preheat your air fryer to 375°F for 5 minutes. While it heats, place the pork belly skin-side down in the air fryer basket. The preheated air fryer will help render the fat immediately, creating that coveted crackling. Don't overcrowd the basket—leave space for air to circulate around the pork belly for even cooking.
Render the Fat and Develop Crispy Skin
Cook the pork belly at 375°F for 30 minutes, then reduce the temperature to 350°F for another 30 minutes. During this time, the fat will begin to render, and the skin will start to crisp. Flip the pork belly skin-side up halfway through—this ensures even browning on both sides. You'll know it's ready when the skin is deep golden brown and the fat has rendered significantly, leaving behind crispy, crackling layers.
Here's the thing—don't open the air fryer during cooking. Every time you peek, you release heat and moisture, which can steam the skin instead of crisping it. If you're worried about doneness, trust the timing and temperature. The pork belly should feel firm to the touch and have a rich, caramelized aroma when it's done.
Rest and Slice for Maximum Juiciness
Once the pork belly is golden brown and crispy, transfer it to a cutting board and let it rest for 10-15 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful. If you slice it too soon, the juices will escape, leaving you with dry, tough meat.
While the pork belly rests, heat a small saucepan over medium heat and combine the 1 tablespoon Apple Cider Vinegar and 1 tablespoon Extra-Virgin Olive Oil. Simmer for 2 minutes to create a simple pan sauce. Once the pork belly has rested, slice it into ¼-inch thick pieces, discarding any large fat chunks if desired. Arrange the slices on a serving platter, drizzle with the pan sauce, and garnish with the 0.25 cup chopped Fresh Rosemary. The rosemary adds a bright, herbal note that cuts through the richness of the pork belly.
Pro Tips For Making Air Fryer Roast Pork Belly
- CUT BELLY IN HALF: Pork belly is thick—don’t fight it. Slice it into two even layers (about 1.5 inches thick) so the air fryer can crisp the outer edges without drying out the center. I learned this the hard way when my first batch came out chewy in the middle.
- SALT BEFORE YOU THINK: Generously coat the pork belly with kosher salt (about 1.5 tablespoons per pound) and let it sit uncovered in the fridge for at least 2 hours—overnight is better. This isn’t just seasoning; it breaks down the fat and makes the crust actually crispy. (Yes, even if you’re impatient like me.)
- CRANK HEAT THEN DROP: Start the air fryer at 400°F for the first 10 minutes to render the fat and get that golden crust going. After that, lower it to 350°F and cook until the internal temp hits 145°F. Skipping the high-heat start means a sad, greasy mess.
- BRUSH WITH VINEGAR MIDWAY: After the first 15 minutes, pull the pork out and brush it with a mix of apple cider vinegar and five-spice powder (1:1 ratio). The acid cuts through the fat and deepens the flavor—don’t skip this, or you’ll miss the real magic. (I know, it sounds weird, but it works.)
Best sauces and condiments for air fryer roast pork belly
Classic Apple Sauce
This is my go-to sauce for pork belly—simple, tangy, and perfect for dipping. Use 2 cups peeled and chopped apples (I love Granny Smith for tartness), ¼ cup apple cider vinegar, 2 tbsp brown sugar, and a pinch of cinnamon.
Simmer for 15 minutes until thickened, then mash slightly. The acidity cuts through the pork's richness beautifully. 🍎
Sweet Chili Glaze
For a Southeast Asian twist, blend ½ cup sweet chili sauce (like Maesri), 2 tbsp honey, 1 tbsp lime juice, and 1 tsp grated ginger. Simmer until slightly thickened, then drizzle over sliced pork belly.
The heat and sweetness balance the pork's fat perfectly. I often serve this with jasmine rice for a complete meal.
Brown Butter Sauce
Brown ¼ cup unsalted butter in a skillet until nutty and golden, then whisk in 1 tbsp heavy cream and 1 tsp soy sauce. Finish with a pinch of white pepper.
This sauce adds depth and a luxurious texture. I like to spoon it over the pork belly just before serving—it melts into the crackling like magic. 🧈
Spicy Hoisin Drizzle
Mix 2 tbsp hoisin sauce, 1 tbsp sriracha, and 1 tsp rice vinegar for a bold, umami-rich drizzle. The hoisin's sweetness contrasts the pork's saltiness, while the sriracha adds a kick.
I brush this on the pork belly during the last 5 minutes of cooking in the air fryer for extra flavor infusion.
Herbed Honey Mustard
Combine 3 tbsp Dijon mustard, 2 tbsp honey, 1 tbsp chopped fresh dill, and 1 tsp apple cider vinegar. This sauce is bright and tangy, cutting through the pork's richness.
I serve it on the side for dipping or drizzle it over the sliced pork belly before garnishing with rosemary.
Smoky Chipotle Crema
Blend ½ cup sour cream, 1 chipotle pepper in adobo, 1 tbsp lime juice, and ½ tsp cumin until smooth. This creamy, smoky sauce adds a layer of complexity.
I love serving it with corn tortillas and sliced pork belly for a fusion-style meal. The heat from the chipotle balances the pork's fat beautifully. 🔥

Frequently asked questions
Can I use pork belly with skin removed for this recipe?
The skin is essential for that coveted crispy crackling! Without it, you'll miss the star of this dish. If you absolutely must use boneless pork belly without skin, look for a thick-cut piece with good marbling—it'll still render beautifully, though the texture will be different. For best results, stick with skin-on pork belly and score it properly for maximum crispiness.
Why does my air fryer pork belly turn out greasy instead of crispy?
Greasy results usually happen when the fat renders too quickly without proper browning. First, score the fat cap deeply in a crosshatch pattern to help render fat evenly. Second, reduce the air fryer temperature to 350°F after the initial 30 minutes at 375°F—this slows fat rendering while allowing the skin to crisp. Finally, never open the air fryer during cooking to prevent steam from interfering with crispiness.
How do I know when the pork belly is fully cooked?
It's done when the skin is deep golden brown and the internal temperature reaches 145°F (measured in the thickest part of the meat). The pork belly should feel firm to the touch and have a rich, caramelized aroma. If you're unsure, let it cook a few more minutes—pork belly continues cooking slightly after removal from the air fryer. The crackling should shatter like glass when pressed gently.
Can I make this ahead of time and reheat it?
Yes! Store cooked pork belly in an airtight container in the fridge for up to 4 days. To reheat, place slices in the air fryer at 350°F for 5-7 minutes until warmed through. For best results, reheat only what you plan to serve immediately—the crackling loses its crispiness over time, but the meat stays tender. The rendered fat solidifies when chilled, so slice through it to serve fresh pieces.
What's the best way to use the rendered fat?
That golden liquid is pure flavor gold! Strain it through a fine-mesh sieve to remove any debris, then store it in a small jar in the fridge. Use it for basting proteins, frying eggs, or sautéing vegetables. You can also drizzle it over roasted potatoes or mix it into sauces for extra richness. Every drop is valuable—don't discard it!
