Season the chicken with salt and pepper, and cook it in a large skillet over medium-high heat with one tablespoon of vegetable oil until golden on one side, approximately 5 minutes.
Flip it, reduce the heat to medium, and cover. Allow to simmer for about 10 more minutes. Transfer to a dish and cover with tin foil to keep warm.
Add the mushrooms, a drizzle of oil and the shallot to the skillet, and sauté until golden.
Deglaze the pan with white wine and reduce this sauce until the wine evaporates.
Remove the pan from the heat and add Boursin Garlic & Fine Herbs, the cooking cream and parsley. Pour the cheese sauce over the chicken.
