Start by preheating your air fryer to 400°F so it's ready when you need it. While it heats up, dry your shrimp thoroughly with paper towels. Mix the cornstarch, panko breadcrumbs, garlic powder, paprika, salt, and pepper in a large bowl until everything is evenly combined.
Add the dried shrimp to this mixture and toss them gently until each piece is lightly coated, then shake off any excess breading.
Spray your air fryer basket with oil and arrange the shrimp in a single layer, making sure they're not touching. Give the tops a light spray of oil too. Cook for 4-5 minutes, then flip each shrimp and spray again before cooking another 4-5 minutes until they're golden brown and opaque all the way through.
While the shrimp cook, whisk together the mayonnaise, sweet chili sauce, sriracha, honey, and rice vinegar until the sauce is smooth and glossy.
When the shrimp are done, you can either toss them gently in the sauce or drizzle it over them if you want to keep maximum crunch.
Notes
Don't overcrowd the air fryer basket - Shrimp need space for air to circulate around them. Cook in batches if necessary to maintain that crispy coating.
Pat shrimp completely dry - Any moisture on the shrimp will create steam in the air fryer and prevent proper crisping. Take an extra minute to dry them well.
Shake off excess breading - Too much coating will fall off and burn in the air fryer basket. A light, even coating is all you need.
Make the sauce while shrimp cook - The timing works perfectly if you prepare the bang bang sauce during those 10 minutes of cooking time.
Serve immediately - These air fryer bang bang shrimp are best when they're fresh and hot. The coating stays crispiest right out of the air fryer.
