Ingredients for air fryer roast pork belly
Restaurant-quality pork belly starts with these 13 essential ingredients—each playing a key role in crispy crusts and rich gravy.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Belly 🐖 | 2 lb | Thick-cut, skin-on preferred |
| Diamond Crystal Kosher Salt 🧂 | ½ cup | For 24-hour dry brine |
| Fresh Celery Stems 🧅 | 1 bunch | Thinly sliced for crown |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for scoring |
| Heavy Cream 🥛 | 1 cup | Full-fat for gravy richness |
| Pork Fatback 🥓 | 4 oz | Diced for gravy depth |
| All-Purpose Flour 🌾 | 2 tbsp | For gravy thickening |
| Fresh Thyme Sprigs 🌿 | 4 whole | For gravy aroma |
| Garlic Cloves 🧄 | 6 cloves | Minced for gravy base |
| Black Peppercorns 🌶️ | 1 tsp | Freshly cracked |
| Apple Cider Vinegar 🍎 | 1 tbsp | For gravy brightness |
| Granulated Sugar 🍬 | 1 tsp | Balances acidity |
| Vegetable Oil 🫒 | 1 tbsp | For air fryer coating |
The pork belly is non-negotiable here—thick-cut, skin-on from Butcher Shop or Whole Foods delivers the best marbling. Look for pieces with visible fat layers; this is what renders into flavor. I always ask for 2-pound slabs since they score better for crisping. The salt? Diamond Crystal dissolves cleaner than table salt, and you'll need it for that 24-hour cure. Trust me, the extra time is worth the melt-in-your-mouth texture. For the celery crown, grab organic bunches—tighter stalks stay crisp longer when thinly sliced.
No thick-cut belly? Regular pork belly with extra scoring works in a pinch, but expect slightly less crisp. Subbing butter for gravy? Olive oil plus extra pork fat keeps it rich. Fresh thyme is ideal, but dried at half the amount won't ruin the dish. The apple cider vinegar can be swapped for white wine vinegar if you're making gravy ahead. For scoring, I use a sharp boning knife—dull blades tear the meat. Pro tip: Chill the pork after scoring to firm up the fat for cleaner cuts. The sugar in gravy? Don't skip it—it rounds out the acidity from the vinegar.
Pork belly keeps 3 days in the fridge post-brine, but cook it within 24 hours for best texture. The celery crown? Wrap it in damp paper towels and store in a sealed container—stays crisp for 2 days. Gravy reheats beautifully—just warm with a splash of cream. For make-ahead meals, freeze portions of cooked pork in gravy; reheat in a 350°F oven** until golden (about 15 minutes). The fatback for gravy? Render it ahead and freeze in ice cube trays for easy future use.

Step-by-step instructions for crispy air fryer pork belly
Transforming pork belly into golden, crackling perfection takes patience—but the air fryer makes it easier than ever.
Dry Brine the Pork Belly for Maximum Crisp
Place the 2 lb pork belly skin-side up on a wire rack set over a baking sheet. Sprinkle all 0.5 cup Diamond Crystal kosher salt evenly over the meat, pressing gently so it adheres. The skin should look uniformly white and dry after salting.
Cover loosely with plastic wrap and refrigerate for 24 hours. This dry brine draws out moisture, ensuring a crispy exterior. Flip the pork belly halfway through if you remember—otherwise, don’t stress. The salt will work its magic either way. After brining, pat the meat dry with paper towels, focusing on the skin where crispiness will form.
Score and Prep for Air Frying
Use a sharp knife to score the pork belly skin in a diamond pattern, cutting about ¼-inch deep without piercing the fat underneath. This creates crispy "windows" while keeping the meat tender. Place the scored pork belly in the air fryer basket and lightly brush both sides with 1 tablespoon vegetable oil—this helps the skin crisp without sticking.
Air fry at 350°F for 45 minutes, flipping halfway. The skin should be golden brown and crispy when done, while the meat remains tender. If you notice the skin browning too quickly, reduce the temperature to 325°F for the second half of cooking. The internal temperature should reach 145°F—use a meat thermometer to check in the thickest part of the meat, avoiding the fat.
Create the Celery Crown Topping
While the pork belly cooks, thinly slice 1 bunch fresh celery stems into ¼-inch rounds. In a small bowl, toss the celery with 1 tablespoon apple cider vinegar, 1 teaspoon granulated sugar, and a pinch of salt. Let it marinate for 10 minutes—this softens the celery slightly and adds brightness.
In a separate pan, melt 0.5 cup unsalted butter over medium heat. Add the marinated celery and cook for 3-4 minutes until tender but still holding its shape. Remove from heat and set aside—this will become the crown topping for your pork belly. The vinegar and sugar balance the celery’s bitterness, making it sweet and tangy.
Make the Savory Gravy
In the same pan used for the celery, add 4 oz diced pork fatback and cook over medium heat until golden and crispy, about 5 minutes. Add 6 minced garlic cloves and 4 whole fresh thyme sprigs, cooking for 1 minute until fragrant. Sprinkle in 2 tablespoons all-purpose flour and stir to coat the fatback.
Slowly pour in 1 cup heavy cream, stirring constantly to avoid lumps. Add 1 teaspoon freshly cracked black peppercorns and simmer for 5-7 minutes until the gravy thickens to a velvety consistency. Taste and adjust seasoning—you might need a pinch more salt or a splash of vinegar to balance the richness. The gravy should coat the back of a spoon but still be pourable.
Assemble and Serve
Slice the pork belly into ½-inch thick slices, keeping the skin intact. Arrange the slices on a platter, fanning them slightly to showcase the crispy skin. Spoon the warm gravy over the top, then scatter the celery crown evenly across the pork. The contrast of crispy, tender, and creamy elements makes this dish unforgettable.
Serve immediately while the skin is still crackling. The celery crown adds a refreshing crunch, while the gravy ties everything together with its savory depth. If you have leftovers, store them separately—reheating crispy pork belly in the air fryer at 300°F for 5 minutes restores its texture beautifully.
Pro Tips For Making Air Fryer Roast Pork Belly
- PREHEAT LIKE IT’S 1985: Your air fryer should scream hot—at least 400°F—before the pork belly goes in. I learned this the hard way after my first batch came out greasy instead of crispy. That initial blast of heat is what locks in the fat and starts the crust right away.
- SALT THE BELLY TWICE: First, dry the pork belly thoroughly with paper towels, then hit it with a heavy hand of Diamond Crystal salt (about 1.5 teaspoons per pound) and let it sit uncovered in the fridge for 12 hours. Rinse it off, pat it dry again, and salt it once more before air frying. Sounds weird, but it works—your crust will be worth the effort.
- DON’T CROWD THE BASKET: Pork belly needs room to breathe, or you’ll end up with soggy fat instead of crispy skin. Cut it into 1-inch-thick slabs and space them at least ½ inch apart. If your air fryer is small, work in batches—trust me, your future self will thank you.
- BASTE WITH THE CREAM: Skip the butter-only basting halfway through—mix equal parts melted unsalted butter and heavy cream (about 2 tablespoons total) for a glossier finish. Brush it on when the pork hits 325°F, then crank the heat back up. The cream adds moisture without making the skin greasy.
Make-ahead tips for air fryer roast pork belly
Prep Ahead Strategy
Start your dry brine the night before—this is the single most important make-ahead step. I always prep my pork belly 24 hours in advance, storing it uncovered in the fridge. The salt draws out moisture while infusing flavor, giving you crispier skin with less effort.
Pro tip: Use a wire rack on a tray to prevent soggy skin during brining. 💡
Gravy Prep Shortcut
Render your pork fatback ahead and freeze it in 1-ounce portions in ice cube trays. When you're ready to make gravy, simply thaw a portion and use it directly—this saves 10 minutes of prep time.
Store the rendered fat in an airtight container for up to 3 months. The fatback adds incredible depth to your gravy without extra cooking time.
Celery Crown Prep
Slice and marinate your celery crown 1 day ahead—store it in an airtight container with the vinegar mixture. When ready to cook, simply sauté it in butter for 3-4 minutes.
This prep step ensures you have a fresh, crisp topping without last-minute chopping. I like to keep the celery refrigerated in its marinade until the final step to maintain texture.
Storage Solutions
Cooked pork belly stores beautifully in the fridge for 3 days when wrapped tightly in plastic wrap and foil. For longer storage, freeze portions in gravy—this preserves both texture and flavor.
When reheating, use the air fryer at 300°F for 5 minutes to restore crispiness. The gravy can be refrigerated separately for up to 5 days or frozen for 3 months.
Reheating Leftovers
To revive leftovers, place pork belly slices in the air fryer basket at 300°F for 5-7 minutes until the skin is crisp again. Add a splash of water to the basket to prevent drying.
For gravy, gently reheat on the stovetop over low heat—never boil, or it will separate. I often reheat gravy in the same pan I made it in for consistency. 🔥
Batch Cooking Tips
Double the recipe and freeze half the pork belly slices with gravy for future meals. When ready to serve, simply reheat in the air fryer. This is perfect for meal prep—just thaw overnight in the fridge.
I often make a big batch on Sundays for quick weeknight dinners. The celery crown can be prepped in advance but is best added fresh when serving for maximum crunch.

Frequently asked questions
Why is the 24-hour dry brine so important for crispy skin?
The dry brine draws out moisture from the skin, creating the perfect surface for crispiness. When you air fry, this dry surface browns beautifully while the fat underneath renders slowly, keeping the meat tender. Skipping the brine means soggy skin—trust me, I’ve tested it both ways!
Can I use regular pork belly instead of thick-cut?
Yes, but you’ll need to score it more aggressively in a diamond pattern to create crispy \"windows.\" Thin-cut belly may cook faster, so check the internal temperature at 145°F and reduce air fryer time to 35-40 minutes. The fat content is what makes pork belly special—don’t skip it!
What if my air fryer isn’t big enough for the whole pork belly?
No problem! Cook the pork belly in batches if needed, but leave space between pieces for proper air circulation. For a 2 lb slab, you might need to flip it once during cooking. The key is maintaining that 350°F temperature consistently—don’t overcrowd the basket.
How do I know when the pork belly is done?
Use a meat thermometer to check the thickest part of the meat (avoiding fat) until it reaches 145°F. The skin should be golden brown and crispy, with no pink remaining. If it browns too quickly, reduce the temperature to 325°F for the second half of cooking time.
Can I make this recipe without the celery crown?
The celery crown adds freshness, but you can serve the pork belly with just gravy and steamed vegetables. For a Southern twist, try serving it with collard greens or cornbread. The gravy is the star—don’t skip that part!
