A classic green bean casserole with a perfectly crispy French’s onion topping, creamy mushroom sauce, and easy pantry ingredients. Perfect for Thanksgiving or any comforting holiday meal.
Split the French’s onions into two portions—mix half into the casserole and sprinkle the rest on top before baking. Add a fresh handful right after baking for extra crunch. If onions brown too fast, tent with foil after 20 minutes. For a dairy-free version, use dairy-free mushroom soup and milk, and dairy-free crispy onions. Leftovers reheat well covered at 325°F for 15 minutes; add fresh onions and broil briefly to refresh topping.
