+# How to Make Chicken Wings in an Air Fryer
+

+![Chicken Wings](./鸡翅中_1.jpg)
+
+Making chicken wings in an air fryer is convenient. Foods with their own fat, like these, taste great and are even better than KFC's. Plus, you don't **have to wash dishes or pots** afterward.
+
+- Cooking time: 40 minutes (3 minutes prep + 20 minutes thawing + 17 minutes cooking)
+- Actual hands-on time: 5 minutes
+
+Estimated cooking difficulty: ★★
+
+## Essential Ingredients and Tools
+
+- Required: Chicken mid-joint wings (Tyson's Orleans-style chicken wings are recommended; if JD has a sale, a 454g bag with about 12 wings costs around 30+ RMB. I've also bought Shangxian and Sunner brands, but they aren't as convenient. Tyson's comes pre-marinated; if you have time, you can buy unmarinated wings and marinate them yourself.)
+- Optional: Dried basil (sprinkled on top purely for aesthetics)
+- Optional: Yunnan Danshan dipping sauce (can be used as a substitute for BBQ seasoning)
+
+## Quantities
+
+- Chicken mid-joint wings: 6 pieces (Tyson's Orleans-style chicken wings; other brands like Sunner's Dudu Wings may be larger, so adjust according to your appetite)
+
+## Instructions
+
+- Take the chicken wings out of the refrigerator, place them skin-side down on a foil-lined baking tray, sprinkle with dried basil, cover with plastic wrap, and let them thaw naturally for 20 minutes.
+- Sprinkle with dried basil, air fry at 200°C for 10 minutes.
+- Flip the wings, sprinkle with dried basil, and air fry at 200°C for 7 minutes.
+
+## Additional Tips
+
+- It is recommended to buy an air fryer with good temperature control; otherwise, the wings might burn.
