This from-scratch green bean casserole features tender-crisp green beans in a rich, creamy mushroom sauce, topped with homemade crispy shallots. It’s a cozy, comforting side dish that’s perfect for holidays or weeknight dinners.
Don’t over-blanch the beans—3 minutes is perfect. Dry shallots thoroughly before coating in flour to ensure even frying. Make shallots up to 2 days ahead and store in an airtight container. Let casserole rest 5 minutes before serving to allow sauce to set. Double the shallots for extra crunch.
