🥘 What is Moo Grob?
Moo Grob (หมูกรอบ) simply means “crispy pork.”
It is one of the most popular Thai dishes, often served in:
- Khao Moo Grob (crispy pork belly on rice)
- Pad Krapao Moo Grob (holy basil stir-fry with crispy pork)
- Pad Kana Moo Grob (stir-fry with Chinese broccoli)
- Noodle soups
- Fried rice
- Or even eaten alone as a snack!
The dish features pork belly cooked until the skin becomes crunchy like glass, and the meat stays soft and flavorful. The secret lies in preparing the skin to puff up during cooking.
My air fryer method makes Moo Grob incredibly simple—no hot oil, no splattering, no long frying time, and no mess.
🍽️ Ingredients (Only 3 Needed!)
Main Ingredient
- Pork belly – 1 large slab (choose one with even layers of meat, fat, and a smooth skin)
Seasonings
- Salt – for skin and seasoning
- Vinegar – helps the skin dry and crackle beautifully
That’s it! No soy sauce, no oil, no special marinade on the skin.
This traditional Thai method relies on good quality pork, drying, and high heat.
📸 Step-by-Step Recipe (Air Fryer Method)
Step 1 — Prepare the Pork Belly
Place the slab of pork belly on a cutting board. Rinse thoroughly and pat completely dry with a towel. Moisture is the enemy of crispy skin, so ensure both the top and bottom are dry.
Step 2 — Boil the Pork Belly (Optional Step)
Some cooks like to boil the pork belly for 10 minutes to soften the skin and help the fat render slightly.
In this recipe, we skip boiling because the air fryer alone creates a perfectly crispy result.
Step 3 — Score the Skin
Use a sharp knife to lightly score the pork skin. This helps the salt and vinegar penetrate and allows the heat to puff the skin more effectively. Do not cut too deep—only the surface layer.
Step 4 — Season the Meat Side
Flip the pork belly over. Rub salt generously into the meat side (not the skin).
Do not season the skin with anything except salt and vinegar.
Step 5 — Dry the Skin
Pat the skin dry again.
Take a moment here—if the skin is not dry, the crackling will not form correctly.
Step 6 — Coat the Skin with Vinegar + Salt
Brush the skin with vinegar (rice vinegar or white vinegar works great).
Sprinkle a thin layer of salt evenly.
This combination dries the skin further and ensures the puffed, bubbly crackling we want.
Step 7 — Air Fry
Place the pork belly skin-side up in the air fryer basket.
- Temperature: 200°C
- Time: 25–30 minutes
Halfway through, check the skin. It should begin to form golden blisters and crackle.
If needed, air fry an extra 5–10 minutes, depending on thickness.
Step 8 — Rest and Slice
Let the pork rest for 10 minutes before slicing. This keeps the meat juicy.
Then slice into thick or thin pieces—your choice!
🧡 Why This Air Fryer Method Works
This simple method creates incredible results because:
1️⃣ Vinegar dries and tightens the skin
Allowing it to crackle without oil.
2️⃣ Salt opens the pores of the skin
Making it crisp faster.
3️⃣ Air fryer heat circulation creates even crisping
Perfect for home cooks.
4️⃣ No oil needed
Traditional Thai Moo Grob requires deep frying.
This version is healthier and easier, with zero splatter.
5️⃣ Minimal ingredients → maximum flavor
The natural flavor of pork belly shines through.

👩🍳 Tips for Perfect Crispy Skin
✔ Dry the skin deeply
Even small moisture can ruin crispiness.
✔ Do not poke holes too deep
Too deep → fat leaks → skin won’t puff.
✔ Air fry skin-side up only
Skin must be fully exposed to heat.
✔ Let it rest before cutting
Prevents moisture from softening the skin.
✔ For extra crispiness:
Add 5–7 more minutes at 220°C at the end.
🔥 Troubleshooting
❗ Skin not crispy?
Dry the skin longer and raise heat at the final stage.
❗ Skin is too hard?
Lower the temperature next time; it may have overcooked.
❗ Pork belly burned on edges?
Trim thinner sections for even cooking.
❗ Meat too dry?
Choose a piece with thicker fat layers.
