Your suspicions are confirmed: We did have the classic green-bean casserole with fried-onion topping on the brain when working on this recipe. But sweet, nutty roasted Brussels sprouts and a woodsy blend of wild mushrooms will make this luxurious variation a hit on even the most traditional holiday table. The fried shallots provide an irresistible savory crunch.
