Preheat and prep: Heat the oven to 400°F (200°C). Lightly oil a baking dish just large enough to fit the salmon.
Season the salmon: Pat fillets dry.
Rub with olive oil and season both sides with salt and pepper.
Build the base: In the baking dish, add broth or wine, lemon juice, and minced garlic. Scatter any quick-cooking veggies (like tomatoes or asparagus) around the edges. They’ll roast and mingle with the sauce.
Add the Boursin: Place salmon in the dish, skin-side down if using.
Break the Boursin into chunks and dot it evenly over and around the fillets. Sprinkle red pepper flakes if you like heat.
Bake: Bake 10–14 minutes, depending on thickness. Salmon is done when it flakes easily and reaches 125–130°F for medium.
The Boursin will melt into a creamy sauce.
Finish: Spoon the melted Boursin sauce over the salmon. Taste and adjust seasoning with salt, pepper, and a squeeze of lemon.
Garnish and serve: Sprinkle with chopped herbs. Serve with roasted potatoes, rice, or crusty bread to soak up the sauce.
