Pat the salmon dry. Use paper towels to remove moisture so the coating crisps up.
Season both sides with salt, pepper, and a pinch of garlic powder.
Mix the sauce. In a small bowl, whisk mayo, sweet chili sauce, sriracha, honey, and vinegar until smooth. Taste and adjust heat and sweetness.
Coat the salmon. Lightly dust each fillet in cornstarch for a thin, crisp crust, or press into panko for extra crunch. Shake off any excess.
Choose your cooking method. Pan-sear: Heat 1–2 tablespoons oil over medium-high heat.
Cook salmon 3–4 minutes per side (skin-side first if using skin-on), until golden and just cooked through.
Oven-bake: Heat oven to 400°F (205°C). Place salmon on a lightly oiled sheet pan. Bake 10–12 minutes, depending on thickness.
Air fry: 390°F (200°C) for 8–10 minutes, lightly oiled basket, until crisp and flaky.
Sauce it up. You can brush the sauce on during the last minute of cooking for a warm glaze, or drizzle generously over the salmon right before serving for a creamy finish.
Garnish and serve. Top with scallions and sesame seeds if you like.
Serve with rice, roasted veggies, or a crunchy slaw.
