A refined, homemade green bean casserole featuring fresh blanched beans, a rich mushroom cream sauce, and a crunchy topping of fried onions and panko. This recipe avoids the sogginess of traditional versions for a perfect texture.
Do not skip the ice bath when blanching beans to maintain texture and color. Ensure mushrooms are browned well to build flavor. If making ahead, assemble but do not bake until ready to serve to prevent soggy topping. For a vegetarian version, substitute chicken stock with vegetable stock.
