A classic green bean casserole with creamy mushroom sauce, tender green beans, and a crispy fried onion topping. Perfect for holidays or any comforting meal.
For best results, don’t skip blanching and drying the green beans. Add topping during last 5-7 minutes to keep onions crispy. Can be assembled a day ahead without topping; add 10 minutes to initial baking time. Double the topping if desired.
