Preheat oven to 450. Place a sheet pan in the oven while it preheats.
Add the brussels sprouts plus 2 tbsp olive oil, the salt and pepper to a bowl. Toss to coat.
Remove the sheet pan from the oven & add the remaining olive oil to the pan, then the brussels sprouts face down. Place in the oven for 30 minutes, flipping halfway.
While the Brussels roast, make the Honey-Boursin cream. Heat the honey over medium heat, then add ¾ block Boursin cheese and stir with a wooden spoon until everything is melted together.
Plate the Brussels, then drizzle the top with the cream, cranberries, pistachios, parsley and remaining crumbled Boursin.
