Preheat the oven to 425°F (220°C) and position a rack on the top level. Line a rimmed baking sheet with parchment paper or a silicone baking mat.
Lay the salmon fillets on the prepared baking sheet, skin-side-down. Season with a pinch of salt and pepper.
In a small bowl, add the remaining ingredients and whisk well to combine.
Pour this mixture over the salmon and use your clean hands to gently rub it all over the top and sides.
Bake for 12 min and no more than 15 min to avoid overcooking the fish. The salmon should be juicy and flake easily when pressed on the top with a fork. Overcooked salmon is super-firm, dry and it will crumble when you cut into it.
