The perfect green bean casserole with creamy mushroom sauce, tender green beans, and crispy fried onions. A delightful Thanksgiving side dish!
For best results, fry onions until light golden. They will crisp further when cooled and baked. Make ahead by preparing sauce and beans and storing them in the fridge. Fry onions a day before.
