Fragrant Crispy Duck, known as Xiang Su Ya, is one of those dishes my family simply cannot resist. There’s a local Sichuan restaurant here in Minnesota that serves an amazing version, and every time we dine there, my kids insist we order it. The duck arrives incredibly aromatic with crispy skin and juicy meat, chopped into bite-sized pieces with the bones intact.

This homemade version is inspired by that restaurant dish and adapted from a recipe by Viet World Kitchen. Over the years, I’ve streamlined the process and tweaked it to make it more practical for home cooking. Instead of the traditional deep-fry method alone, I pressure cook the duck in the Instant Pot to tenderize it, then finish it in the air fryer to crisp up the skin. The result is wonderfully crispy and fragrant without the mess of deep frying.

Why You’ll Like This Recipe

1. Restaurant-quality at home – This dish recreates the bold aromatic flavors of the Sichuan classic Xiang Su Ya without complicated restaurant equipment.
2. Ultra fragrant seasoning – Toasted Sichuan peppercorns and Chinese five-spice give the duck a deeply aromatic flavor.
3. Tender and juicy meat – Pressure cooking or steaming ensures the duck becomes perfectly tender before crisping.
4. Two finishing options – Choose between deep frying for maximum crispiness or air frying for a cleaner and lighter method.
5. Great use of the whole duck – Nothing goes to waste since the cooking juices and rendered fat can be saved for future cooking.

Ingredients and Substitutions

1. Whole duck (about 4–5 pounds) – Fresh duck works best, but frozen duck that has been fully thawed also works well.
2. Sichuan peppercorns – These give the duck its signature numbing fragrance. If unavailable, substitute with freshly ground black pepper, though the flavor will be different.
3. Chinese five-spice powder – Adds warmth and complexity to the seasoning.
4. Table salt – Essential for seasoning and helping the skin dry.
5. Shaoxing rice wine – Adds aroma and helps remove any gamey flavor. Dry sherry is a good substitute.
6. Fresh ginger – Adds fragrance and balances the richness of the duck.
7. Green onions – Provide aromatic sweetness during cooking.
8. Cornstarch – Helps create a crisp crust before frying.
9. Water – Used to form the starch slurry.
10. Light soy sauce – Adds savory depth to the coating.

Comparison of cooking methods

Air Fryer Pros
1. Much less oil required
2. Cleaner cooking process
3. Less splattering and mess
4. Easier for home kitchens
5. Still produces very crispy skin
Air Fryer Cons
1. Slightly less crispy than deep frying
2. Bones won’t become crunchy
3. May require cooking in batches depending on air fryer size
Deep Fryer Pros
1. Maximum crispiness
2. Skin becomes extremely crunchy
3. Even small bones become crispy and edible
4. Closest to restaurant-style results
Deep Fryer Cons
1. Uses a lot of oil
2. Can be messy and splattery
3. Requires more cleanup
4. Strong frying smell in the kitchen
Conclusion: For everyday cooking, I usually choose the air fryer because it’s simple and far less messy. But if you want the ultimate restaurant-style crispiness, the deep fryer definitely wins.

Storage & Reheating

1. Store leftover duck in an airtight container in the refrigerator for up to 3 days.
2. Reheat in the air fryer at 350°F for about 5–8 minutes to re-crisp the skin.
3. Avoid microwaving if possible since it softens the crispy skin.
4. Leftover duck can also be chopped and used in fried rice or noodle dishes.

Frequently Asked Questions

1. Why does the duck need to dry in the refrigerator for 24 hours?
   Drying the skin helps remove moisture so it can crisp properly during frying.
2. Can I skip the Instant Pot step?
   Yes. The duck can be steamed instead, which is the more traditional method.
3. Do I have to cut the duck in half before frying?
   It’s much easier and safer to fry half a duck rather than a whole duck. But you are welcome to keep the duck whole for presentation if you that’s what you prefer
4. Why add cornstarch before frying?
   The cornstarch slurry helps form an extra crispy crust.
5. Can I prepare the duck ahead of time?
   Yes. The duck can be cooked and dried a day in advance, then fried just before serving.

Fragrant Crispy Duck is one of those special dishes that feels restaurant-worthy but is surprisingly achievable at home. The combination of aromatic spices, tender duck meat, and shatteringly crisp skin is incredibly satisfying. While the traditional deep-fry method produces the crispiest results, the air fryer version is impressively good and far more practical for everyday cooking. Either way, once you taste that fragrant crispy skin, you’ll understand why this dish has become a must-order whenever my family visits our favorite Sichuan restaurant.
