Preheat the air fryer to 375 degrees F and spray the basket with cooking spray.
Season the fish generously with kosher salt and black pepper on all sides. Place it skin-side down in the air fryer basket and cook for 10 minutes.
While the fish cooks, combine the honey, soy sauce, fresh garlic, and red crushed pepper.
Brush the fish with the honey garlic glaze, increase the temperature to 400 degrees F. and cook for 2 minutes or until fully cooked through and the top is crispy and golden brown.
Notes
Let the Chilean sea bass sit at room temperature for at least 20 minutes before cooking it. Otherwise, if the fish is too cold, it will cook unevenly.
Make sure you cook the fish for 10 minutes before glazing it, honey burns quickly and if cooked for 12 minutes, it will burn!
