I love the flavors of French onion soup. It's rich and beefy while still being sweet and comforting. I don't always feel like laboring over the stove, taking forever to caramelize those onions, though. That's where the recipe below comes in. Using a package of French onion soup mix provides a shortcut to favorite flavors.
This casserole is also an effective way to use up any leftover chicken or rice. I always buy the rotisserie chickens on sale at the store, but I can never eat the entire chicken. Having precooked chicken on hand can be a serious lifesaver. It turns a slow-cooked meal into a quick-and-easy one.
