Prep the oven and pan: Heat the oven to 425°F (220°C). Line a sheet pan with foil or parchment.
Lightly oil the surface so the skin doesn’t stick.
Make the glaze: In a small bowl, whisk together sweet chili sauce, soy sauce, lime juice, rice vinegar, garlic, ginger, and sesame oil. Add a pinch of red pepper flakes if you want more heat. Taste and adjust: more lime for tang, more soy for salt, more chili sauce for sweetness.
Season the salmon: Pat salmon dry with paper towels.
Sprinkle lightly with salt and pepper. Place filets skin-side down on the prepared pan.
Brush with glaze: Spoon or brush a generous layer of glaze over the tops and sides. Reserve 1–2 tablespoons of glaze for finishing.
Roast: Bake for 8–10 minutes, depending on thickness.
The salmon should be nearly opaque with a little translucence in the center.
Optional broil for caramelization: Switch the oven to broil for 1–2 minutes to blister and thicken the glaze. Watch closely to avoid burning.
Rest and finish: Let the salmon rest for 2 minutes. Brush with the reserved glaze for a glossy finish.
Sprinkle with sesame seeds and scallions. Serve with lime wedges.
