Parmesan cheese adds a bit of sharpness to this popular Italian side dish.
Bring milk, salt, and oil to a slow boil in a large saucepan over medium heat. Gradually add polenta, whisking constantly. Reduce heat to low. Cook, stirring often, until thickened, about 3 minutes. Remove from heat. Stir in butter and Parmesan. Drizzle with oil, and season with pepper. Serve immediately.
