# Air Fryer Pork Belly: Crispy Crackling Every Time
If there's one dish that separates a good air fryer cook from a great one, it's pork belly with perfect crackling. That gloriously crunchy, golden skin that shatters when you bite into it — the kind you'd normally only get at a restaurant or after hours of careful oven roasting. The good news? Your air fryer can deliver that same result in a fraction of the time, with far less fuss and mess.
In this guide, we'll walk you through everything you need to know about cooking pork belly in an air fryer: from choosing the right cut and preparing the skin, to nailing the temperature and timing for crackling that's crispy every single time. Whether you're cooking a full slab for a Sunday roast or slicing it into bite-sized pieces for a weeknight dinner, this is the guide you've been waiting for.

Why the Air Fryer Is Perfect for Pork Belly
Traditional pork belly crackling requires high, dry heat — exactly what an air fryer excels at. The rapid circulation of hot air in an air fryer creates the ideal environment for rendering fat and crisping skin without drying out the meat underneath.
Compared to oven roasting, the air fryer offers several advantages:
- Faster cooking time — a full slab of pork belly can be done in under an hour
- More consistent results — the circulating air ensures even heat distribution
- Less mess — fat drips into the basket tray rather than splattering your oven
- Energy efficiency — uses significantly less electricity than a full-sized oven

Choosing the Right Cut
Not all pork belly is created equal. For the best crackling results, look for:
- Skin-on pork belly — this is non-negotiable. The skin is what becomes crackling, so make sure it's intact
- Even thickness — a uniform slab cooks more evenly than one that tapers at the ends
- Good fat-to-meat ratio — you want visible layers of fat and meat, which is what gives pork belly its rich, melt-in-your-mouth texture
- Score marks already cut — some butchers will score the skin for you, which saves time and effort
In Australia, you can find skin-on pork belly at most butchers, Asian grocery stores, and major supermarkets. Ask your butcher to score the skin if it hasn't been done already — they're usually happy to help.

Preparing the Pork Belly
Preparation is where crackling is won or lost. Follow these steps carefully for the best results.
Drying the Skin
Moisture is the enemy of crackling. The drier the skin, the crispier it will become.
- Pat the pork belly dry with paper towels — both the skin and the meat side
- Place it uncovered on a wire rack in the fridge for at least 4 hours, or ideally overnight
- Before cooking, pat it dry again to remove any remaining moisture
This step is often skipped, but it makes an enormous difference. Don't rush it.
Scoring the Skin
If the skin hasn't been scored, use a sharp knife or a Stanley knife to cut parallel lines about 1 cm apart across the skin. Cut through the skin and into the fat, but not into the meat. This allows the fat to render out and the skin to puff up and crisp.
Seasoning
Keep the seasoning simple to let the pork flavour shine:
- Skin side: Rub generously with fine salt (not flakes — fine salt penetrates better). Some cooks also add a small amount of bicarbonate of soda, which raises the pH of the skin and helps it crisp up faster
- Meat side: Season with salt, pepper, garlic powder, and any other spices you enjoy — smoked paprika, fennel seeds, and Chinese five spice all work beautifully
Let the seasoned pork belly sit at room temperature for 30 minutes before cooking.

Air Fryer Pork Belly: Step-by-Step Method
What You'll Need
- 800g–1.2kg skin-on pork belly slab
- Fine salt
- Olive oil or neutral cooking oil
- Your choice of spices for the meat side
Cooking Instructions
Step 1: Preheat your air fryer
Preheat your air fryer to 400°F (204°C) for 5 minutes. A hot start is essential for getting the crackling process going quickly.
Step 2: Initial high-heat blast
Place the pork belly skin-side up in the air fryer basket. Cook at 400°F (204°C) for 20–25 minutes. This initial blast of heat starts the rendering process and begins to puff and blister the skin.
Step 3: Lower the temperature
Reduce the temperature to 340°F (171°C) and continue cooking for another 25–30 minutes. This allows the meat to cook through gently while the fat continues to render.
Step 4: Final crackling blast
If the crackling isn't fully crisped to your liking, increase the temperature back to 400°F (204°C) for a final 5–10 minutes. Watch it closely during this stage — crackling can go from perfect to burnt quickly.
Step 5: Rest before slicing
Remove the pork belly from the air fryer and rest it on a wire rack for 10 minutes before slicing. This allows the juices to redistribute and makes slicing much easier.
Total Cooking Time
For an 800g–1.2kg slab: approximately 55–65 minutes total, depending on thickness and your specific air fryer model.

Troubleshooting: Why Isn't My Crackling Crispy?
Even with the best preparation, crackling can sometimes be stubborn. Here are the most common issues and how to fix them:
The skin is chewy, not crunchy
This almost always comes down to moisture. Make sure you've dried the skin thoroughly before cooking, and that you're using fine salt rather than coarse flakes. If the skin is still chewy after cooking, blast it at 400°F (204°C) for an additional 5–10 minutes.
The crackling is uneven
This can happen if the pork belly isn't lying flat in the basket. Try to find a piece that fits your air fryer basket without curling up at the edges. If needed, use a small piece of foil to prop up any areas that are lifting.
The meat is dry
If the meat is drying out before the crackling is done, your air fryer may be running hot. Try reducing the temperature by 20°F (about 10°C) and extending the cooking time slightly. An instant-read thermometer is your best friend here — the internal temperature of the meat should reach 160°F (71°C) for safe eating.
The fat isn't rendering
This usually means the scoring wasn't deep enough. The cuts need to go through the skin and into the fat layer. If you notice the fat isn't rendering during cooking, carefully score the skin more deeply (using tongs and a knife) and continue cooking.

Air Fryer Pork Belly Bites
If you prefer bite-sized pieces rather than a full slab, pork belly bites are a fantastic option — and they cook even faster.
Method
- Cut the pork belly into 3–4 cm cubes, skin-on
- Season generously with salt, pepper, garlic powder, and a touch of Chinese five spice
- Preheat the air fryer to 380°F (193°C)
- Cook for 20–25 minutes, shaking the basket halfway through
- For extra crispiness, increase to 400°F (204°C) for the final 5 minutes
Pork belly bites are perfect as a starter, a party snack, or served over steamed rice with a drizzle of hoisin sauce. They're also great for meal prep — they reheat beautifully in the air fryer at 350°F (177°C) for 5 minutes.

Flavour Variations to Try
Once you've mastered the basic method, experiment with these flavour profiles:
Chinese-Style Pork Belly
Marinate the meat side (not the skin) in a mixture of soy sauce, hoisin, honey, garlic, and ginger for 2–4 hours before cooking. The marinade caramelises beautifully during cooking and pairs wonderfully with the crispy crackling.
Fennel and Garlic
Rub the meat side with crushed fennel seeds, garlic, lemon zest, and olive oil. This classic Italian-inspired combination is a crowd-pleaser and works particularly well for a Sunday roast.
Smoky Paprika and Chilli
For those who like a bit of heat, combine smoked paprika, chilli flakes, cumin, and garlic powder. This works brilliantly with pork belly bites served alongside a cooling yoghurt dip.
Honey Soy Glaze
In the last 5 minutes of cooking, brush the meat side (not the skin) with a mixture of honey and soy sauce. The glaze caramelises and adds a gorgeous sticky sweetness that contrasts with the salty crackling.

Choosing the Right Air Fryer for Pork Belly
Not all air fryers are equally suited to cooking a full slab of pork belly. Here's what to look for:
Basket Size
You'll need at least a 5–6 litre basket to fit a standard 800g–1kg slab of pork belly. For larger cuts or if you're cooking for a family, consider a 7–8 litre model or a dual-basket air fryer that gives you more flexibility.
Temperature Range
Make sure your air fryer can reach at least 400°F (204°C) — this is essential for getting the crackling properly crisped. Most modern air fryers can reach this temperature, but it's worth checking before you buy.
Wattage
Higher wattage models (1800W–2400W) heat up faster and maintain temperature more consistently, which is important for crackling. Lower wattage models may struggle to maintain the high heat needed.

Tips for Consistent Crackling Results
After testing this method many times, here are the tips that make the biggest difference:
- Always dry the skin overnight — this single step has the most impact on crackling quality
- Use fine salt, not flakes — fine salt draws out moisture more effectively
- Don't overcrowd the basket — air needs to circulate freely around the pork belly
- Preheat the air fryer — starting with a hot air fryer gives the crackling a head start
- Don't open the basket too often — every time you open it, you lose heat and disrupt the cooking process
- Rest the meat before slicing — this is non-negotiable for juicy results
- Use a meat thermometer — take the guesswork out of doneness

Frequently Asked Questions
Can I cook frozen pork belly in the air fryer?
It's not recommended to cook pork belly from frozen, as the skin won't dry out properly and the crackling will be disappointing. Always thaw pork belly completely in the fridge before cooking.
How do I store leftover pork belly?
Store leftover pork belly in an airtight container in the fridge for up to 3 days. To reheat, place it in the air fryer at 350°F (177°C) for 5–8 minutes. The crackling will re-crisp beautifully.
Can I cook pork belly in a smaller air fryer?
Yes, but you may need to cut the slab into smaller pieces to fit. Pork belly bites (as described above) are a great option for smaller air fryers.
Do I need to use oil on the skin?
A very light brush of oil on the skin can help the salt adhere and promote browning, but it's not strictly necessary. Too much oil can actually prevent the skin from crisping properly.
What's the best internal temperature for pork belly?
Pork belly is safe to eat at an internal temperature of 160°F (71°C), but for the best texture — tender, melting meat — aim for 185°F–195°F (85°C–91°C). At this temperature, the collagen in the meat has broken down and the fat has fully rendered.
