Preheat the oven to 400°F (204°C) and line a rimmed baking sheet with parchment paper.
Pat the salmon fillets dry using paper towels to ensure proper adhesion of the topping.
Arrange the fillets on the baking sheet and season the tops with kosher salt and black pepper.
Spread approximately 1.3 ounces of Boursin cheese evenly across the top surface of each salmon fillet.
In a small mixing bowl, combine panko breadcrumbs and olive oil, stirring until the crumbs are uniformly coated.
Press the panko mixture firmly into the cheese layer on each fillet to form a crust.
Transfer the baking sheet to the center rack of the oven and bake for 12 to 15 minutes, depending on thickness, until the internal temperature reaches 145°F (63°C).
Remove from the oven and garnish with chopped parsley. Serve immediately with lemon wedges.
