French Onion Green Bean Casserole
This French Onion Green Bean Casserole is a stellar gluten free replacement for that popular green bean casserole with the cream of mushroom soup and the crispy French fried onions. This updated version borrows elements of French onion soup to create a casserole that might just upstage the old classic. With caramelized onions, gruyere cheese and a crispy bread crumb topping, this casserole has the flavor of French onion soup in a green bean casserole that is simply outstanding. Although this side dish has a holiday feel but it’s simple enough for a weeknight meal too.
