Preheat the air fryer: Set it to 390–400°F (200°C). A hot basket helps the glaze caramelize and prevents sticking.
Mix the glaze: In a small bowl, whisk sweet chili sauce, soy sauce, lime juice, sesame oil, ginger, garlic, and red pepper flakes.
Taste and adjust. It should be sweet, tangy, and a little spicy.
Prep the salmon: Pat the fillets dry with paper towels. Season lightly with salt and black pepper.
Dry fish browns better and helps the sauce stick.
Oil the basket: Lightly spray the air fryer basket or place a piece of parchment designed for air fryers. Don’t block the vents.
Glaze the fillets: Brush about half the glaze over the tops and sides of the salmon. Reserve the rest for basting and serving.
Air fry, skin-side down: Arrange fillets in a single layer with space between them.
Cook for 6 minutes.
Baste and finish: Open the basket, brush on more glaze, and cook 2–4 more minutes, depending on thickness. Aim for an internal temp of 125–130°F for medium, or 145°F for well done. The salmon should flake easily.
Rest briefly: Let the salmon sit 2 minutes.
This keeps it juicy and helps the glaze set.
Garnish and serve: Spoon a bit of the remaining glaze over the top. Add green onions, sesame seeds, and cilantro. Serve with lime wedges.
