01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease a baking dish.
02 - Pat the salmon fillets dry with paper towels. Place them skin-side down on the prepared baking sheet.
03 - Drizzle olive oil over the salmon. Season each fillet with salt, black pepper, and crushed red pepper flakes if using.
04 - In a small bowl, combine the Boursin cheese and heavy cream. Mix until smooth and spreadable.
05 - Evenly spread the Boursin mixture over the top of each salmon fillet.
06 - Arrange lemon slices over and around the salmon.
07 - Bake for 15–20 minutes, or until the salmon flakes easily with a fork and the cheese topping is bubbling and lightly golden.
08 - Remove from the oven. Sprinkle with chopped chives and dill before serving.
