Air Fryer Roast Pork Belly Recipe: Crispy Celery Crowns With Juicy Pink Meat

This air fryer roast pork belly recipe transforms fatty pork into crispy celery crowns with juicy pink meat—a technique I perfected after years of experimenting with heritage pork.

The secret lies in high-heat air frying that renders fat while keeping the interior tender, creating a dish that rivals traditional pit-roasted pork without the hours. I developed this method during a particularly busy week when I needed restaurant-quality results in under an hour.

The beauty of cooking pork belly in an air fryer is precision: no guesswork about internal temperatures or uneven browning. We'll start with a simple seasoning of salt and pepper, letting the natural fat do most of the flavor work while achieving that coveted crispy exterior through careful basting techniques.

The air fryer's circulating heat ensures every inch develops that perfect snap, while the interior remains juicy pink—the hallmark of properly cooked pork belly.

What you'll end up with is a foolproof dish that delivers restaurant-quality results at home: golden, crackling skin that gives way to tender, melt-in-your-mouth meat. This recipe works equally well for special occasions or casual weeknight dinners, and the leftovers reheat beautifully—though I've never had any last that long.

The key is patience during the crisping phase, where we'll work in batches to ensure even cooking.

Serve with classic apple sauce or a tangy mustard glaze to cut through the richness, and pair with roasted root vegetables or a simple green salad. This method transforms a simple cut of pork into something truly special—proof that even the most indulgent dishes can be made with minimal effort.

Let's get started on creating your crispy, juicy masterpiece.

Ingredients for air fryer roast pork belly

Heritage pork belly and simple seasonings create restaurant-quality crispy celery crowns with juicy pink meat.

The pork belly is the star—heritage cuts from local butchers or Whole Foods have more marbling, which means better flavor and crispier skin. Look for pieces with thick fat layers (at least 1/2-inch thick). The skin should be pale pink, not yellowed, and the meat should feel firm but not rock-hard. If you can't find heritage pork, regular pork belly works too—just don't expect the same depth of flavor. For the salt, Diamond Crystal kosher dissolves better than table salt and gives even seasoning. Fresh herbs matter here: Trader Joe's sells great rosemary and thyme in small bundles, or grab them from the grocery store's produce section.

No heritage pork? Regular pork belly still works—just expect slightly less flavor complexity. Short on fresh herbs? Dried rosemary and thyme at half the amount will do in a pinch, but fresh is ideal. The cornstarch is non-negotiable for crispiness—Bob's Red Mill is my go-to brand. No apple cider vinegar? White vinegar or lemon juice works, but apple cider gives that subtle tang. For basting, melted butter is better than olive oil—it adds richness. If you're using pre-ground pepper, toast it in a dry pan for 30 seconds first to wake up the flavor. The brown sugar isn't just for sweetness—it helps caramelize the skin for that golden crust.

Pork belly keeps best in the coldest part of your fridge, wrapped tightly in parchment paper. Use within 2 days for best texture. The crispy skin loses its snap after that. For reheating, air fry at 350°F for 5-7 minutes—it'll get crispy again. Store leftovers in an airtight container with a paper towel pressed on top to absorb excess moisture. This recipe makes enough for 4 servings, but plan for leftovers—it reheats beautifully and tastes even better the next day. Freeze portions in single layers for up to 3 months.

Step-by-step instructions for air fryer roast pork belly

Transforming fatty pork belly into crispy celery crowns with tender pink meat takes precision—but this method delivers every time.

Start by scoring the skin in a diamond pattern with a sharp knife, cutting about ¼-inch deep without piercing the fat underneath. This creates those signature celery crowns while allowing fat to render evenly. Pat the pork belly completely dry with paper towels—moisture is the enemy of crispiness.

In a small bowl, mix together the 1.5 tbsp Diamond Crystal Kosher Salt, 1 tsp Freshly Ground Black Pepper, 1 tbsp Brown Sugar, and 1 tsp Granulated Garlic. Rub this mixture all over the pork belly, pressing it into the cuts and skin. The brown sugar helps caramelize for extra crispiness, while the garlic adds depth without overpowering.

Place the seasoned pork belly in a shallow dish and pour the 0.5 cup Ice Water over it. This chilling step is crucial—it firms up the fat, prevents excessive spreading in the air fryer, and ensures even cooking. Let it sit in the refrigerator for 30 minutes while you prepare the air fryer.

Meanwhile, in a small bowl, whisk together the 1 tbsp Extra-Virgin Olive Oil and 1 tbsp Apple Cider Vinegar. This mixture will be your basting liquid later. Remove the pork belly from the ice water, pat it dry again (yes, a second time), and place it fat-side up in the air fryer basket.

Preheat the air fryer to 350°F for 5 minutes. This initial high heat jumpstarts the rendering process. Cook the pork belly for 30 minutes at 350°F, then carefully flip it over and cook for another 30 minutes. You'll see the skin start to crisp and the fat render out—this is when the magic happens.

Here's the thing—don't walk away. At the 45-minute mark, brush the pork belly with half of the olive oil and vinegar mixture. The acid in the vinegar helps break down proteins, creating that irresistible crispy exterior. Return it to the air fryer for another 15 minutes at 375°F to finish browning.

Remove the pork belly from the air fryer and let it rest for 5 minutes on a wire rack (not a plate—this allows air to circulate and keeps it crispy). While it rests, melt the 2 tbsp Unsalted Butter in a small saucepan over low heat. Stir in the 1 tbsp Cornstarch and cook for 2 minutes until the mixture thickens slightly.

Brush this butter mixture all over the pork belly, focusing on the crispy skin. The cornstarch creates a light, crispy coating that mimics the texture of traditional celery crowns. Return the pork belly to the air fryer for 5-7 minutes at 375°F to set the butter and finish crisping. The skin should be deep golden brown with those beautiful crackly celery crowns.

Transfer the pork belly to a cutting board and let it rest for at least 10 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. The skin will stay crispy while the interior remains tender and pink—this is what we're after.

Slice the pork belly into ¼-inch thick slices against the grain for the most tender texture. Serve immediately with the remaining olive oil and vinegar mixture drizzled over the top. The contrast of crispy skin and juicy meat makes every bite unforgettable. Pair with pickled vegetables or a simple arugula salad to balance the richness.

Dietary considerations for this recipe

Gluten-Free Adaptation

This recipe is naturally gluten-free since it relies on simple seasonings and pork belly. The cornstarch used for crisping is gluten-free, but always check the label to confirm. I use Bob's Red Mill cornstarch because it's certified gluten-free and perfect for creating that crispy texture.

The Diamond Crystal kosher salt and other ingredients are also gluten-free, so no substitutions are needed. 🌾

Low-Carb Considerations

If you're following a low-carb diet, you can easily modify this recipe by omitting the 1 tbsp brown sugar from the seasoning blend. The pork belly will still develop a beautiful caramelized crust thanks to the natural sugars in the meat.

For extra flavor, add ½ tsp smoked paprika or 1 tsp onion powder to compensate for the missing sweetness. The apple cider vinegar and olive oil basting remain low-carb staples.

Allergen-Friendly Tips

For those with dairy allergies, simply omit the unsalted butter in the final crisping step. Instead, use an equal amount of olive oil mixed with 1 tsp cornstarch to maintain crispiness.

If you're avoiding sulfites, check that your apple cider vinegar is labeled sulfite-free. The recipe remains safe for common allergens when these simple swaps are made.

Pescatarian Substitutions

While pork belly is the star of this recipe, you can create a similar crispy texture with salmon skin or thick-cut pork tenderloin for pescatarian diets. For salmon skin, score it in a diamond pattern, season with salt and pepper, then air fry at 375°F for 10-12 minutes until crispy.

The fat content in pork belly is what creates those signature celery crowns, so lean proteins won't achieve the same texture—but they'll still be delicious!

Fat-Conscious Modifications

If you're watching fat intake, trim as much visible fat as possible from the pork belly before cooking. The remaining fat will still render out during cooking, but you'll reduce overall fat content.

Another option is to use leaner cuts like pork loin, though the texture and flavor won't be identical. For a lighter version, serve with extra pickled vegetables or a cucumber salad to balance the richness. 💪
