Preheat your oven to 400°F (200°C).
Lightly grease a baking dish with oil or line it with parchment paper.
In a small bowl, combine the Boursin cheese, minced garlic, lemon zest, lemon juice, and half of your chosen olive oil or melted butter. Stir until smooth.
Pat the salmon fillets dry using a paper towel. Drizzle the remaining olive oil or melted butter over each fillet, then season with salt and black pepper.
Place the seasoned salmon fillets in your prepared baking dish with skin side down. Spoon the Boursin cheese mixture evenly over each fillet.
Bake in your preheated oven for 15-20 minutes until it flakes easily and reaches an internal temperature of 145°F (63°C). Let it rest briefly before garnishing with fresh parsley and serving with lemon wedges.
