Preheat your oven to 400°F (200°C). This ensures even cooking and perfectly tender salmon.

Lightly grease a baking dish or line it with parchment paper for easy cleanup and to prevent sticking.

In a small bowl, mix together the Boursin cheese, minced garlic, lemon zest, lemon juice, and half of the olive oil or melted butter until smooth and well combined.

Pat the salmon fillets completely dry with paper towels. Drizzle the remaining olive oil over the fillets and season with salt and black pepper.

Place the salmon fillets in the prepared baking dish, skin side down if using skin-on. Spoon the Boursin cheese mixture evenly over each fillet, spreading gently with the back of a spoon.

Bake in the preheated oven for 15-20 minutes, depending on the thickness of your fillets. The salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).

Remove from the oven and let rest for 2 minutes. Garnish with chopped parsley and serve alongside fresh lemon wedges.
