This air fryer roast pork belly recipe transforms fatty cuts into crispy, caramelized perfection with minimal effort. After years of perfecting pork at Atlanta's The Smoky Pig, I've adapted my restaurant techniques for home cooks—no smoker required.
The secret lies in high heat and careful scoring that creates an irresistible bark while keeping the meat tender inside.
What sets this recipe apart is the air fryer's ability to render fat without a deep fryer, creating a golden, crackling exterior that shatters at every bite.
We'll score the belly in a diamond pattern (critical for even cooking), coat it in just enough oil to encourage browning, and monitor the temperature closely to prevent overcooking. The result? A dish that rivals traditional pit-roasted pork but arrives on your table in under 40 minutes.
By the final minute, you'll have pork so crisp it sounds like crackling when you slice through it, with fat that melts at room temperature. This technique preserves all the rich, savory depth of pork belly while delivering the satisfying crunch home cooks crave.
The best part? Every bite contains that magical contrast between crispy exterior and velvety interior.
Serve thinly sliced with cracklings scattered on top, paired with roasted root vegetables or a simple apple-cider glaze. The air fryer method means you can enjoy this restaurant-quality pork without the hours of smoking or the mess of deep frying. Let's get cooking—your taste buds will thank you.

The pork belly is everything here—thick-cut, 1-inch slices with skin-on for that legendary crackle. Ask your butcher for pork belly if your store doesn't carry it pre-sliced; look for good marbling and avoid anything too lean. I always grab mine from Whole Foods or a local butcher shop—they know how to cut it right. The skin should be intact and the fat should be white and firm. If it smells funky or has yellow spots, walk away. For scoring, a sharp knife is non-negotiable—dull blades crush the meat instead of creating clean cuts. And trust me, the diamond pattern is key—it creates those gorgeous, even crispy pieces.
No avocado oil? Grapeseed or peanut oil work just as well—just avoid anything with a low smoke point. Running out of fresh rosemary? Dried works at one-third the amount, but fresh is worth the trip to the grocery store. The apple cider vinegar adds a bright note that cuts through the richness—substitute with lemon juice if that's what you've got. Want more smokiness? Add a pinch of liquid smoke (just a quarter teaspoon) to the oil mixture. And if you're worried about the sugar caramelizing too much, use brown sugar instead—it's less likely to burn. The herbs? Tear them by hand instead of chopping—releases more flavor.
Pork belly keeps beautifully in the fridge for 3-4 days if wrapped tightly in foil, but honestly, it's best enjoyed fresh. For leftovers, reheat in the air fryer at 350°F for 5-7 minutes until crispy again. The cracklings? Save them—they're pure magic sprinkled over salads or soups. I always make extra because they disappear fast. Store any unused pork belly in the freezer for up to 3 months, but let it thaw in the fridge overnight before cooking. And if you're feeling fancy, save some of the rendered fat to cook eggs in later—it's next-level delicious.

Step-by-step instructions for crispy air fryer pork belly
Here's how to transform simple pork belly into restaurant-worthy crispy perfection.
Score and Season the Pork Belly
Place the 2 lb pork belly skin-side up on a cutting board. Using a sharp knife, make deep diagonal cuts through the fat layer only—about ½-inch apart and ¼-inch deep. This scoring creates crispy pockets while keeping the meat tender. Pat the skin completely dry with paper towels; any moisture will prevent crispiness.
In a small bowl, mix together the 1.5 tbsp Diamond Crystal kosher salt, 1 tsp freshly ground black pepper, 1 tsp garlic powder, and 0.5 tsp smoked paprika. Rub this generously over both sides of the pork belly, pressing the spices into the meat. In another small bowl, whisk together the 1 tbsp apple cider vinegar and 1 tsp granulated sugar. Brush this mixture evenly over the seasoned pork belly. The vinegar will tenderize while the sugar promotes caramelization.
Preheat and Prepare the Air Fryer
Place two sheets of air fryer liners in your air fryer basket. Preheat the air fryer to 375°F for 5 minutes—this ensures even cooking from the start. While it preheats, arrange the 2 sprigs fresh rosemary and 2 sprigs fresh thyme on a small plate. Lightly crush them with the flat side of a knife to release their aromatics, then place them in the air fryer basket along with the pork belly.
Here's the thing—don't worry if the pork belly doesn't fit perfectly. The air fryer will work with what you have, but if it's crowded, you might need to cook it in batches. The key is to leave at least ½-inch space around the edges for proper air circulation, which is what creates that coveted crispy bark.
Cook Until Golden and Crispy
Place the seasoned pork belly skin-side down in the air fryer basket. Cook at 375°F for 25 minutes. After 25 minutes, use tongs to flip the pork belly skin-side up. Increase the temperature to 400°F and continue cooking for another 15-20 minutes until the skin is deep golden brown and crispy. You'll know it's ready when the skin releases easily from the meat and the internal temperature reaches 195°F.
Real talk: The pork belly might look underdone inside at first, but that's normal. The fat will render and the meat will become tender as it rests. Don't be tempted to open the air fryer early to check—every time you do, you lose heat and moisture, which can ruin the crispiness you're working so hard to achieve.
Rest and Slice for Maximum Juiciness
Once the pork belly is perfectly crispy, remove it from the air fryer and transfer it to a cutting board. Tent loosely with aluminum foil 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 skip this step, you'll end up with dry, tough meat.
After resting, slice the pork belly into ½-inch thick slices against the grain. The fat should be beautifully rendered and the meat should be tender enough to pull apart with a gentle tug. Serve immediately while still warm, with the crispy skin on top for that perfect first bite. The rendered fat will pool on the plate—this is the magic that makes every bite irresistible.
Pro Tips For Making Air Fryer Roast Pork Belly
- CRANK THE HEAT FIRST: Start your air fryer at 400°F (200°C) for the first 10 minutes—this sears the skin and renders fat aggressively. After that, drop to 350°F (175°C) to finish cooking evenly. I used to cook it at a steady 375°F and ended up with greasy, uneven crispiness every time.
- SCORE THE SKIN BEFORE SALTING: Use kitchen shears to make shallow cuts (about ¼-inch apart) in the pork belly’s skin before seasoning—this helps the fat render out faster and creates more surface area for crisping. I skipped this once and spent 20 minutes flipping the belly to get even browning.
- SALT IN LAYERS, NOT ALL AT ONCE: Apply half the kosher salt right after scoring, then add the rest halfway through cooking. This prevents the skin from becoming too salty on the outside while the meat stays juicy inside. My first attempt had me dumping all the salt at once, and the crust tasted harsh.
- LET IT REST—NO EXCUSES: Take the pork belly out of the air fryer and tent it loosely with foil for 10 minutes before slicing. This lets the juices redistribute, or you’ll end up with dry, stringy meat. I know, I know—you’re eager to eat it. But trust me, the wait makes it worth it.
Storing and reheating this dish
Refrigerator Storage
Store cooked pork belly in an airtight container with the crispy skin facing up to preserve that coveted texture. I wrap mine tightly in parchment paper first, then transfer to a container—this prevents sogginess.
Keep it refrigerated for up to 4 days, but honestly, it's best enjoyed within 2 days when the fat is still at its peak. The rendered fat will solidify slightly in the fridge, but it'll melt beautifully when reheated. 💪
Freezer Preservation
For longer storage, freeze pork belly in vacuum-sealed bags or heavy-duty freezer bags with all the air removed. I like to portion it into 1-inch thick slices before freezing—this makes reheating easier later. Label with the date and freeze for up to 3 months.
Thaw overnight in the fridge before reheating. Pro tip: Place the frozen pork belly in a cold water bath for faster thawing if you're in a hurry. 🧊
Reheating in Air Fryer
My favorite method for reheating is back in the air fryer at 375°F for 5-7 minutes. Place the slices in a single layer with the crispy side up, then spray lightly with avocado oil to restore that golden bark.
The high heat revives the crispiness while keeping the meat tender. For extra flavor, brush with a little apple cider vinegar before reheating—it cuts through any richness that might have developed during storage. ✨
Oven Reheating Method
If you don't have an air fryer, use a broiler setting for 3-4 minutes per side. Preheat the oven to 425°F and place the pork belly slices on a wire rack over a baking sheet to allow air circulation.
Watch closely—they can go from perfect to burnt in seconds. For extra crispiness, broil for just 2 minutes at the end. This method works well for small batches but can dry out larger portions. 🔥
Microwave Caution
If you're in a real pinch, use the microwave on medium power for 1-2 minutes, covered with a damp paper towel. The result won't be crispy, but it'll be warm and tender.
For better texture, transfer to a skillet and sear for 30 seconds per side on high heat after microwaving. This two-step process gives you back some of that coveted crunch. Honestly, though, I consider this the "last resort" method. 💡
Serving Leftovers
Use your leftover pork belly in creative ways beyond reheating. Chop it into small cubes for tacos, stir-fries, or fried rice. The rendered fat makes everything taste richer. I also love using it in pork belly ramen or as a topping for roasted potatoes.
Save the crispy skin pieces—they're perfect for garnishing soups or salads. Every bite of leftovers reminds me why I fell in love with this cut of meat in the first place. 🍴

Frequently asked questions
Can I use thicker or thinner pork belly slices?
For best results, stick with 1-inch thick slices—this thickness ensures the fat renders properly while the meat stays tender. Thinner slices (½-inch) may cook too quickly and lose moisture, while thicker slices (> 1.5 inches) risk uneven cooking and dryness. The 1-inch target balances crispy exterior and juicy interior perfectly.
Why is my pork belly not crispy?
Crispy pork belly relies on three key factors: dry skin, proper scoring, and consistent high heat. Pat the skin completely dry before cooking, score in a diamond pattern (not too deep), and avoid opening the air fryer early. If it's still soft, try increasing the temperature to 400°F for the final 5-10 minutes.
How do I know when the pork belly is fully cooked?
Use a meat thermometer to check the internal temperature—it should reach 195°F in the thickest part. The skin should also be deep golden brown and release easily from the meat. If you don't have a thermometer, look for these visual cues: crispy, crackling skin and fat that's rendered but not pooling excessively.
Can I make this recipe with boneless pork belly?
Yes, but expect slightly different results. Boneless pork belly cooks faster and may not develop the same dramatic crispy skin. If using boneless, reduce the cooking time by 5-7 minutes and monitor closely. For extra crispiness, brush with avocado oil halfway through cooking. The meat will still be delicious but less luxurious than bone-in.
What's the best way to serve this pork belly?
Slice thinly against the grain and serve immediately with the crispy skin on top. Pair with roasted root vegetables, a tangy apple-cider glaze, or simple steamed greens. The rendered fat makes everything taste richer—
