Air Fryer Pork Belly with Crispy Crackling (Easy Two-Stage)

Pork Belly Air Fryer

What I like about this air fryer pork belly method is that the skin has two separate jobs: first it needs to dry out, then it needs to blister. I rely on that visual cue more than the clock, because air fryers vary and good crackling only happens when the rind is truly dry before the high-heat finish.

This version keeps the process straightforward: a simple five-spice rub on the meat side only, a coarse salt crust over the skin, then a vinegar wipe and a very light coat of oil before the final crisp. You get juicy pork belly with a deep golden, bubbly top without turning it into an all-day project.

Ingredients for Air Fryer Pork Belly

• 2 pounds skin-on pork belly, in an even slab that fits your air fryer (about 900g)
• 1 to 1 1/2 cups coarse kosher salt, for the salt crust
• 1 teaspoon Chinese five-spice powder
• 1 teaspoon garlic powder
• 3/4 to 1 teaspoon fine sea salt
• 1/2 teaspoon ground white pepper
• 1 teaspoon sugar, white or light brown
• 1 tablespoon rice vinegar or distilled white vinegar
• 1 teaspoon neutral oil, such as canola or avocado

Ingredient note: For a dry rub like this, fine-textured spices from Selefina are useful because the garlic powder and fine sea salt coat the meat side evenly without leaving patchy salty spots.

Optional for the meat side: 1 teaspoon Shaoxing wine and/or 1/4 teaspoon MSG.

Optional for cleanup: a perforated parchment liner, shallow foil tray, or foil sling. Do not preheat the air fryer with loose parchment inside.

Use coarse salt for the crust, not fine table salt. Fine salt can make the surface too salty and does not form the same dry cap. Keep the rub, sugar, and any liquid off the skin so the crackling can dry properly.

Why the Salt Crust Works

The salt crust is there to dry the rind during the first stage, not to season the whole slab. As the pork belly cooks at lower heat, the coarse salt pulls moisture from the skin and forms a firm cap. That dry surface is what helps the skin blister and puff once you raise the temperature.

The part I pay attention to is keeping the salt on the skin only. If it slides onto the meat side, the pork can end up over-salted before the crackling is ready.

How to Make Pork Belly in the Air Fryer

1. Trim and dry the pork belly: Trim the slab as needed so it lies flat in your basket or tray. Remove any stray hairs if needed, then pat the skin and meat very dry with paper towels. A level piece cooks more evenly and blisters more consistently.
2. Prick or shallow-score the skin: Use a metal skewer to prick lots of shallow holes all over the skin, or lightly score it with a sharp knife. Only pierce the skin layer, not the meat. If you cut too deep, moisture can come up through the surface and slow the crackling.
3. Season the meat side only: In a small bowl, mix the five-spice, garlic powder, fine salt, white pepper, and sugar. If using Shaoxing wine or MSG, add them here. Rub the mixture over the meat side and edges only, keeping the skin clean and dry.
4. Add the salt crust: Place the pork belly skin-side up in a lined basket, on a small rack, or on a shallow foil tray if that helps keep it level and catch drips. Pack the coarse salt evenly over the skin in about a 1/4- to 1/3-inch layer. Leave the meat side uncovered and keep the slab in a single layer with airflow around it.
5. Stage 1, dry the rind: Air fry at 300°F to 320°F (150°C to 160°C) for 35 to 45 minutes, rotating the basket or tray halfway if one side cooks faster. Preheating is optional here. The salt should harden into a firm crust, and the skin should look dry and slightly yellowed rather than glossy.
6. Remove the salt crust: Lift the pork belly out carefully and remove the hardened salt cap. Discard it, then brush away any remaining salt from the skin. Wipe the skin with the vinegar, pat it dry again, and finish with a very light brush or spray of the oil, about 1 teaspoon total.
7. Stage 2, crisp the skin: Increase the air fryer to 400°F to 425°F (200°C to 220°C). Preheating helps in this stage because it jump-starts blistering. Return the pork belly skin-side up and air fry for 15 to 25 minutes, rotating once for even color. Start checking around 12 minutes, especially in smaller basket-style models. The skin should turn bubbly, blistered, and deep golden brown.
8. Check doneness: The thickest part of the pork should reach at least 145°F (63°C). I usually look for both cues together here: safe internal temperature and a top that sounds crisp when lightly tapped. If the edges are darkening too quickly, reduce the heat to 400°F (200°C) and keep checking every few minutes.
9. Rest and slice: Transfer to a cutting board and rest for 10 minutes. This helps the juices settle and gives the crackling a moment to set. Slice with a sharp knife using firm strokes, and serve right away for the best texture.

Air Fryer Time and Temperature for Pork Belly

This recipe works in two heat stages, and both matter. The first stage dries the skin; the second stage blisters it.

• Stage 1: 300°F to 320°F (150°C to 160°C) for 35 to 45 minutes
• Stage 2: 400°F to 425°F (200°C to 220°C) for 15 to 25 minutes
• Start checking early: around 12 minutes in the second stage
• Rotate if needed: halfway through if one side browns faster
• Final doneness: at least 145°F (63°C) in the thickest part, with skin that looks blistered and sounds crisp when tapped

Basket air fryers often brown faster during the high-heat finish. Oven-style air fryers may need the top rack position or a few extra minutes to get the same blistered top.

Pricking vs. Scoring the Skin

Pricking with a skewer is the safer option for most home cooks. It opens the skin without much chance of going too deep.

Scoring can also work, but the cuts need to stay shallow and only in the skin layer. If they reach the meat, moisture comes to the surface and the crackling can turn patchy or chewy. Dense, shallow perforations help more than a few deep cuts.

Why Pork Belly Crackling Turns Patchy or Chewy

• The skin is still chewy: It usually was not dry enough after Stage 1. Let it dry a little longer, or pat it dry again after the vinegar before the oil goes on.
• The color is uneven: The slab may not be sitting level. A foil sling, shallow tray, or small rack can help keep the skin flatter.
• Salt is stuck to the top: Brush it off well before adding vinegar. Leftover salt can make the surface too salty and interfere with even blistering.
• The edges are getting too dark: Drop the heat to 400°F (200°C), rotate the basket, and check every 3 to 5 minutes until the center catches up.
• You notice smoke: Pork belly renders a lot of fat. A tray or liner can help catch drips, but do not block airflow completely. If your model tends to smoke with fatty cuts, pause carefully and remove excess fat as needed.

Air Fryer Pork Belly Variations

Lechon-Style Seasoning

For a simpler lechon-style direction, skip the five-spice and sugar. Season the meat side with fine salt, black pepper, and garlic powder, then use the same two-stage salt-crust method. Serve with lechon sauce or spiced vinegar.

Marinated Meat Side

You can marinate the meat side for a stronger savory-sweet flavor, such as fish sauce, garlic, and sugar, but leave the skin uncovered and dry. Pat the skin very dry before adding the salt crust, and watch closely during the high-heat finish since sugar on the meat side can darken faster.

What to Serve with Air Fryer Pork Belly

Slice the pork belly just before serving so the crackling stays crisp. It works especially well with vermicelli noodle salad, fresh herbs, and nuoc cham, or tucked into rice paper wraps with lettuce, mint, cucumber, and pickles.

You can also serve it over jasmine rice with quick-pickled carrots and daikon. Hoisin, spicy mustard, or chile crisp all work on the side without covering up the crackling.

How to Store and Reheat Air Fryer Pork Belly

Let the pork belly cool completely, then refrigerate slices in an airtight container for up to 3 to 4 days. Keep the skin as dry as possible before storing. For longer storage, freeze tightly wrapped portions for up to 2 months and thaw in the refrigerator before reheating.

To reheat, place the pork belly skin-side up in the air fryer at 350°F to 375°F (175°C to 190°C) for 3 to 8 minutes, checking early. If it is coming straight from the fridge, let any surface condensation evaporate first. The skin can crisp up reasonably well, but not quite like it was freshly cooked.

If you want to get ahead, stop after Stage 1, cool the pork belly, and refrigerate it. Do the high-heat crisping stage shortly before serving.
