Preheat oven to 350.
In a safe oven dish add Boursin cheese wheel, two lemons cut in half, shallots, garlic head, extra virgin olive oil, salt and pepper. Cook in oven for 40 minutes.
Bring salted water to a boil and cook pasta, saving 2/3 cup pasta water for the sauce.
Once cheese sauce is done cooking in the oven, add pasta, fresh basil, and pasta water. Stir until combined and top with lemon zest.
