A favorite green in Italian cooking where it's a "must" in traditional wedding soup, escarole stands up perfectly as the main ingredient in this quick bean bake, given its dense, spinach-like texture and punchy flavor. Leeks, garlic, and rosemary add to the dish's unmistakably Italian flair. And the crunchy, nutty Parmesan and walnut topping make this dinner-in-under-an-hour casserole anything but ordinary! Hearty enough to stand alone alongside a salad of sliced tomatoes, this casserole would also be perfect on a holiday sideboard or party buffet as a complement to roasted meats or poultry.
