Featuring fresh green beans and caramelized onions, this homemade green bean casserole is just about as clean as it gets. Rather than relying on a cream-based soup, it's held together by a creamy puree of parsnips and mushrooms! The caramelized onion topping still delivers the buttery onion flavor that we all love, without the deep-fried grease and flour to go along with it. All of our favorite flavors covered, without the heavy food-coma to follow!
