Drizzle the spaghetti squash with oil. Place an even number of tomatoes in each squash. Place 1 piece of Boursin on top. Bake 45 to 55 minutes. Cover with foil if Boursin starts to brown.
Instead of reaching for a box of pasta, use this golden-threaded squash in dishes like spaghetti and meatballs, in place of pizza crust, or as the foundation of a baked spaghetti squash casserole.
