This air fryer roast pork belly recipe delivers restaurant-quality crackling without the oven's mess or wait. After years of perfecting pork at The Smoky Pig, I've adapted my technique for home kitchens—where crispy, golden skin meets tender, melt-in-your-mouth meat in under 2 hours. The secret? A two-stage cooking process that ensures even crispiness while keeping the interior juicy.
What sets this apart is the air fryer's precision heat, which creates crackling without the need for a roasting pan or hours in the oven. We'll start with a high-heat sear to render fat and build flavor, then finish with a low-and-slow phase that transforms tough belly into silky perfection. No special equipment beyond your air fryer and a meat thermometer—just the right technique.
By the time you're done, you'll have pork belly so crisp it shatters with every bite, with fat that renders into a glossy, savory pool. The skin will be golden and crackly, while the meat inside stays tender enough to cut with a fork. This is the kind of dish that turns weeknight dinners into special occasions—without the fuss of traditional roasting.
Pair it with tangy apple slices, pickled vegetables, or a simple green salad to balance the richness. The leftovers? Even better the next day, as the flavors deepen and the crackling intensifies. Let's get started on this game-changing pork belly recipe that'll have your guests asking for seconds.
Ingredients for air fryer roast pork belly
Find these ingredients at your butcher and pantry—everything you need for restaurant-style pork belly.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🐖 | 2 lb | Skin-on, thick-cut preferred |
| Kosher Salt 🧂 | 1 ½ tbsp | Diamond Crystal preferred |
| Fresh Black Peppercorns 🌶️ | 1 tsp | Coarsely ground |
| Garlic Cloves 🧄 | 6 cloves | Smashed, skin-on |
| Fresh Rosemary 🌿 | ½ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For coating |
| Apple Cider Vinegar 🍏 | 1 tbsp | For marinade |
| Honey 🍯 | 1 tbsp | For glaze |
| Cornstarch 🌾 | 1 tbsp | For crisping |
| Water 💧 | 1 tbsp | For cornstarch slurry |
The pork belly is the star, so pick a thick-cut piece with good marbling—the fat is what makes it crispy. Local butchers often have the best cuts, or check the meat section at Whole Foods or Costco for pre-sliced belly. If you can't find fresh rosemary, dried works (use half the amount), but fresh is ideal. The garlic should be firm and smell pungent—no soft spots. For the olive oil, California brands like Corto or Otto add a nice fruity note that pairs well with pork.
No fresh rosemary? Dried oregano at half the amount works in a pinch, though it won’t be as aromatic. Running out of apple cider vinegar? White vinegar or lemon juice keeps the tang. The cornstarch slurry is non-negotiable for that perfect crackling—don’t skip it. If you’re feeling fancy, swap the honey glaze for a brown sugar and soy sauce mix for a deeper umami kick. And trust me, the extra-virgin olive oil is worth the splurge here—it’s what makes the skin shine.
Store the pork belly uncovered in the fridge for 1-2 days max before cooking—the skin needs to dry out for crispiness. The marinade ingredients (vinegar, honey, herbs) can be mixed ahead and kept in the fridge for up to 3 days. Once cooked, leftovers reheat beautifully—wrap in foil and bake at 350°F for 15-20 minutes. The crackling gets even better the next day, so plan ahead if you’re serving a crowd.

Step-by-step instructions for crispy air fryer pork belly
Here's how to transform fatty pork belly into irresistible crackling using just your air fryer.
Prepare the Pork Belly for Maximum Crisp
Start by scoring the pork belly skin in a diamond pattern using a sharp knife, cutting about ¼ inch deep without piercing the fat underneath. This creates more surface area for crisping and helps render the fat evenly. Pat the skin completely dry with paper towels—moisture is the enemy of crispy crackling.
In a small bowl, combine the 1.5 tablespoons kosher salt, 1 teaspoon coarsely ground black peppercorns, ½ cup chopped fresh rosemary, and ¼ cup fresh thyme leaves. Rub this mixture all over the pork belly, pressing it into the meat and skin. Let it sit uncovered in the refrigerator for at least 1 hour—this dry-brining step ensures deep flavor penetration and helps render the fat.
Create the Glazing Mixture
While the pork belly rests, make the glaze by whisking together the 2 tablespoons extra-virgin olive oil, 1 tablespoon apple cider vinegar, and 1 tablespoon honey in a small bowl. This combination of acid and sweetness will caramelize beautifully during cooking, creating a sticky, flavorful crust.
After the pork belly has rested, brush this mixture generously over the skin side. Focus on the scored areas where the fat will render and crisp. The glaze will help create that signature crackling texture while adding a perfect balance of sweet and savory flavors.
Cook in the Air Fryer for Perfect Crisp
Preheat your air fryer to 375°F for 5 minutes. Place the pork belly skin-side down in the air fryer basket, leaving space around it for air circulation. Cook for 20 minutes, then flip the pork belly and cook for another 20 minutes. The skin should be golden brown and crispy, with fat rendering out and beginning to crisp.
Here's the trick: After the second 20 minutes, increase the temperature to 400°F and cook for an additional 10-15 minutes until the skin is deep golden brown and the crackling is fully formed. You'll know it's ready when the skin makes a satisfying crackling sound when touched and the internal temperature reaches 145°F.
Finish with Cornstarch for Extra Crunch
In a small bowl, mix the 1 tablespoon cornstarch with the 1 tablespoon water to create a slurry. Brush this lightly over the crispy skin just before serving. The cornstarch will absorb the rendered fat and create an additional layer of crispy crackling that's irresistible.
Let the pork belly rest for 5 minutes before slicing. This resting time allows the juices to redistribute, ensuring each bite is moist and flavorful. Slice into ¼-inch thick pieces and serve immediately with the rendered fat spooned over the top for maximum flavor impact.
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 pork belly’s exterior fast and locks in juices. After that, drop to 350°F (175°C) to finish cooking; I learned the hard way that low-and-slow from the start gives you sad, greasy pork instead of crispy edges.
- SLICE THE BELLY THIN: Cut the pork belly into ½-inch (1.25 cm) thick slices before seasoning—thicker pieces stay chewy no matter how long you cook them. Yes, it’s extra work, but you’ll get that melt-in-your-mouth texture everyone craves, not a rubbery mess.
- SALT IN LAYERS: Don’t just sprinkle salt once. After the initial dry-brine (30 minutes before cooking), pat the pork dry again, then hit it with another layer right before air frying. The first salt draws out moisture, the second creates that addictive crust—skip either, and you’re left with bland, sticky pork.
- USE A MEAT THERMOMETER: Pork belly is forgiving, but pull it at 145°F (63°C) internal temp—any higher, and it’ll turn out dry. I used to eyeball it and overcook it every time; now I set a timer for 20 minutes after hitting that temp, then rest it under foil. Crispy skin, juicy meat—no guesswork.
Best sauces and condiments for air fryer roast pork belly
Classic Apple Cider Glaze
My go-to sauce for pork belly is a simple yet effective apple cider glaze made with ½ cup apple cider vinegar, ¼ cup honey, and 1 tablespoon Dijon mustard. Simmer this mixture until it thickens slightly, then brush it over the pork belly skin during the final 10 minutes of cooking. The acidity cuts through the richness while the honey adds a caramelized sweetness that pairs perfectly with the crackling. I like to finish it with a sprinkle of flaky sea salt right before serving. 🍏
Spicy Soy-Ginger Drizzle
For a Southeast Asian-inspired twist, I make a fiery soy-ginger drizzle that adds depth and heat. Combine ¼ cup soy sauce, 2 tablespoons rice vinegar, 1 tablespoon grated fresh ginger, and 1 teaspoon sriracha. Reduce this sauce by half over medium heat until it's syrupy, then drizzle it over sliced pork belly. Garnish with thinly sliced scallions and toasted sesame seeds for crunch. This works especially well with the air fryer method because the high heat caramelizes the soy beautifully. 🌶️
Brown Sugar-Bourbon Reduction
When I want to impress guests, I reach for a brown sugar-bourbon reduction that adds a smoky depth. Melt ¼ cup brown sugar in a saucepan, then deglaze with 2 tablespoons bourbon (I use Buffalo Trace for its caramel notes). Add 1 tablespoon apple cider vinegar and simmer until thickened. Pour this over the pork belly just before serving—it creates a glossy, sticky coating that enhances every bite. Pair it with charred cornbread for a Southern-inspired feast. 🥃
Honey-Mustard Cream Sauce
For a lighter option that still packs flavor, I whip up a honey-mustard cream sauce using ¼ cup Greek yogurt, 1 tablespoon Dijon mustard, 1 tablespoon honey, and a squeeze of lemon juice. This sauce adds a tangy contrast to the rich pork belly and works beautifully as a dipping sauce for the crackling. It’s especially refreshing when served with a crisp arugula salad dressed in lemon vinaigrette. 🥄
Pickled Vegetable Accompaniment
While not a sauce, I can’t skip mentioning quick-pickled vegetables as the perfect condiment. Thinly slice cucumbers, red onions, and carrots, then pickle them in a mix of 1 cup apple cider vinegar, 1 tablespoon sugar, and 1 teaspoon salt. Let them sit for at least 30 minutes before serving. The bright acidity cuts through the pork’s richness, and the crunch adds texture. I often serve this with the pork belly slices to balance the meal. 🥒
Rendered Fat as Sauce
The real magic? The golden, rendered pork fat that pools underneath the belly as it cooks. Don’t discard it—this liquid gold is the ultimate sauce. Spoon it over the sliced pork belly before serving, or use it to crisp up garlic bread or roasted potatoes. It’s packed with flavor and adds an extra layer of richness that your guests will love. I always save a little to drizzle over the final plate. 💛

Frequently asked questions
Can I use a regular oven instead of an air fryer for this recipe?
For oven cooking, preheat to 425°F and roast the pork belly on a wire rack over a baking sheet for 45-50 minutes, flipping halfway. The air fryer's precision heat just makes it faster and more efficient—no need for a full oven preheat or extra space. The scoring and cornstarch techniques work the same way in both methods.
How do I know when the pork belly is done without a meat thermometer?
Look for these cues: The skin should be deep golden brown with crispy crackling that sounds like Rice Krispies when touched. The internal meat should be fork-tender but not dry—it should pull apart easily with minimal resistance. If you're unsure, cut into a small section: it should be 145°F internally (like warm chicken) and juices should run clear.
Can I make this recipe ahead of time?
Yes! Cook the pork belly up to 145°F internal temp, then cool completely. Store in an airtight container in the fridge for up to 3 days. Reheat by wrapping in foil and baking at 350°F for 15-20 minutes. The crackling will be even better the next day as it re-crispifies.
Why did my pork belly skin turn soggy instead of crispy?
This usually happens from one of three things: not drying the skin thoroughly before cooking, skipping the cornstarch slurry, or overcrowding the air fryer. Always pat the skin very dry with paper towels, apply the cornstarch just before serving, and leave space around the pork for proper air circulation. The air fryer needs room to work its magic!
What's the best way to serve leftover pork belly?
Slice into ¼-inch thick pieces and serve cold or reheated. Try it in banh mi sandwiches with pickled veggies, fried rice for extra richness, or even pork belly tacos with slaw. The rendered fat makes amazing garlic bread or roasted potatoes—just drizzle it on and broil for 2-3 minutes until crispy.
