Air Fryer Roast Pork Belly Recipe: Crispy Celery Crowns Over Savory Herb Gravy

This air fryer roast pork belly recipe delivers restaurant-quality crispiness without the mess of a smoker. After years of perfecting pork belly techniques—from my CIA training to running a 2,000-pound-a-week pit—this method finally cracked the code for home cooks.

The secret? High heat, careful basting, and a crispy celery crown that transforms ordinary pork into something extraordinary.

Most recipes fail because they don't account for the air fryer's rapid heat transfer. I've adjusted temperatures and timing to ensure crispy skin while keeping the meat tender inside.

You'll work with a 2-pound cut (about 1-inch thick), seasoned simply with salt and pepper, then roasted until the edges caramelize and the internal temperature hits 145°F. The celery crown—a technique I learned from Charleston pitmasters—adds texture and visual appeal that turns this into a showstopper dish.

What you'll end up with is golden, crackling pork belly that practically melts in your mouth, topped with a delicate celery crown that adds a satisfying crunch.

The savory herb gravy—made from the rendered pork fat and aromatics—ties everything together, creating a dish that's rich, flavorful, and perfect for special occasions or weeknight dinners. This is the kind of pork belly that makes people ask, "How did you get it so crispy?"

The best part? No smoker required. With just an air fryer, a few simple ingredients, and about 45 minutes of hands-off cooking time, you'll have a dish that rivals any BBQ competition entry. Let's get started on creating pork belly that'll impress even the most discerning guests.

Ingredients for air fryer roast pork belly

Simple ingredients, big restaurant-style results—this pork belly transforms with crispy perfection.

The pork belly is the star, and quality matters. Look for cuts with good marbling—Costco or Whole Foods usually have the best. A 2-pound cut (about 1-inch thick) works perfectly for an air fryer. If yours is thicker, trim it down for even cooking. The celery crown? Use fresh, crisp celery—no wilted stems. For the herbs, grab fresh parsley, thyme, and rosemary from the grocery store's produce section; they'll add that professional touch to your gravy.

No fresh herbs? Dried works at half the amount—just don't skip them entirely. Running low on apple cider vinegar? Lemon juice or white vinegar will do in a pinch, but apple cider adds that perfect tang. The butter in the gravy is non-negotiable—unsalted, full-fat for richness. If you're watching calories, you can use half butter and half olive oil, but trust me on the full-fat version. For the celery crown, if you can't find whole celery sticks, cut regular celery into 3-inch pieces—just make sure they're uniform for even cooking.

Store the pork belly uncovered in the fridge for up to 2 days before cooking—this helps render some fat and concentrate the flavor. The celery crown can be prepped a day ahead and kept in the fridge, but add the vinegar and oil right before air frying. The rendered pork fat from cooking? Save it for gravy or future recipes—it's liquid gold. Leftovers keep for 3-4 days in the fridge, but honestly, this tastes even better the next day as the flavors meld.

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

Transform tender pork belly into irresistible crispy bites with this foolproof air fryer method.

Pat the 2 lb pork belly completely dry with paper towels—this is non-negotiable for crispy skin. Place it fat-side up on a cutting board and score the fat in a diamond pattern using a sharp knife, cutting down to but not through the meat. This creates channels for the seasoning to penetrate and helps render the fat evenly.

Generously rub all sides with the 1.5 tbsp kosher salt and 1 tsp freshly ground black pepper. Press the seasoning into the meat so it adheres well. Let it sit uncovered on a wire rack for 30 minutes at room temperature—this helps the seasoning stick and ensures even cooking. I like to place it on a tray to catch any excess moisture.

Preheat your air fryer to 375°F for 5 minutes. Place the seasoned pork belly fat-side down in the air fryer basket, leaving space around it for air circulation. Cook for 25 minutes, then flip and continue cooking for another 20-25 minutes until the internal temperature reaches 145°F and the skin is deep golden brown with crispy edges.

Here's the thing—don't walk away during this step. The air fryer works fast, and you want to catch that moment when the skin turns from golden to mahogany. If it starts to brown too quickly, reduce the temperature to 350°F for the last 5 minutes to prevent burning. The pork is done when a meat thermometer inserted into the thickest part reads 145°F and the skin is crispy enough to crackle.

While the pork cooks, prepare the celery crowns by cutting the 12 whole celery sticks diagonally into 3-inch lengths. In a small bowl, toss the celery with the 1 tbsp apple cider vinegar and let it sit for 5 minutes. This acidity helps tenderize the celery slightly and adds a bright contrast to the rich pork.

Arrange the celery crowns on a parchment-lined baking sheet and air fry at 375°F for 8-10 minutes until they're tender but still holding their shape. You want them to be slightly charred at the edges for that smoky flavor. Keep them warm while you finish the gravy.

In a small saucepan, melt the 2 tbsp butter over medium heat. Add the sliced onion and cook for 5 minutes until softened. Add the smashed 4 garlic cloves, 4 sprigs fresh rosemary, and 8 whole fresh thyme (stems included) and cook for 2 more minutes until fragrant.

Pour in 1 cup of water (or the pork drippings if you prefer extra flavor) and bring to a simmer. Let it reduce by half, about 8-10 minutes, until it thickens into a rich sauce. Stir in the 0.25 cup chopped fresh parsley and season with additional salt and pepper if needed. The gravy should coat the back of a spoon and be fragrant with herbs.

Transfer the cooked pork belly to a cutting board and let it rest for 10 minutes before slicing. This resting period allows the juices to redistribute, ensuring each bite is moist and flavorful. While it rests, arrange the celery crowns on a platter and spoon the herb gravy over the top.

Slice the pork belly into ½-inch thick slices and serve immediately. The result should be crispy, crackling skin with tender, juicy meat underneath, topped with vibrant celery crowns and herby gravy. This dish is perfect for a special dinner—it's impressive yet simple to make.

Regional styles of this recipe

Charleston-Style Crispy

In Charleston, we take our pork belly seriously—this method comes straight from the Lowcountry tradition of slow-roasting whole hogs. The key difference here? Instead of a smoker, we use the air fryer to mimic that crispy bark while keeping the meat tender.

I learned this technique from Master Chef Chen, who adapted it from traditional Southern pit cooking. The secret is the diamond scoring of the fat—this creates those signature crispy "crowns" that Charleston pitmasters love. 🌟

Georgia BBQ Twist

Back in my hometown of Georgia, we love our pork belly with a sweeter, slightly smokier profile. For a Georgia-style variation, add 1 tbsp brown sugar to your seasoning mix and a splash of hickory-flavored liquid smoke (just ½ tsp) when making the gravy.

This gives it that familiar Southern sweetness while keeping the crispy texture intact. Serve with peach jam on the side for dipping—trust me, it’s a crowd-pleaser at family gatherings. 🍑

Atlanta Pitmaster's Touch

When I was running The Smoky Pig in Atlanta, we perfected this dish for large groups. For a true Atlanta touch, add 1 tsp smoked paprika and ½ tsp cayenne pepper to the seasoning.

We also like to finish the pork with a quick broil in the air fryer for 2-3 minutes at the end to get that extra-crispy skin. Pair it with collard greens and cornbread for a full Southern spread. The cayenne adds just enough heat to balance the richness. 🔥

Southeast Fusion

For a fusion twist, try a Cajun-inspired version by adding 1 tsp Cajun seasoning (like Tony Chachere’s) to the pork’s seasoning. Use green onions instead of celery in the crowns and swap the herb gravy for a spicy remoulade made with mayo, hot sauce, and capers.

This fusion brings the bold flavors of Louisiana to your air fryer pork belly—perfect for a spicy kick without losing the crispy texture. 🌶️

Classic Southeast Sides

No Southern pork belly dish is complete without the right sides. In the Southeast, we pair this with creamy mac and cheese, buttery cornbread, or sautéed okra. For a lighter option, try shaved cabbage slaw with a tangy vinegar dressing.

The crispy pork belly stands up beautifully to these classics, making it a well-rounded meal. These sides are staples in my kitchen—simple, flavorful, and always a hit. 🥗
