In a mixing bowl, combine the mayonnaise, sriracha, and sweet chili sauce. Whisk thoroughly until the mixture is smooth and well combined. Taste and adjust the spice level if necessary. Set aside.
In another bowl, add the buttermilk. Toss the peeled and deveined jumbo shrimp in the buttermilk until well coated.
In a separate shallow dish, combine the cornstarch and breadcrumbs. Take each shrimp from the buttermilk and dredge in the cornstarch and breadcrumb mixture until fully coated.
Preheat your air fryer to 400°F (200°C) for about 5 minutes.
Spray the basket of the air fryer lightly with avocado oil. Place the coated shrimp in a single layer, making sure not to overcrowd them.
Air fry the shrimp for about 8-10 minutes, flipping halfway through for even cooking. They should be golden brown and crispy when done.
Once cooked, remove the shrimp from the air fryer and place them on a serving platter. Drizzle with the creamy chili sauce and garnish with fresh parsley. Serve immediately for the best flavor and texture.
