A streamlined version of the classic green bean casserole, featuring creamy mushroom sauce, tender-crisp green beans, and a double layer of crunchy fried onions and toasted panko. Ready in under 30 minutes, it’s comfort food reimagined for busy weeknights.
For best texture, don’t skip blanching the beans. Pat beans dry to avoid watery casserole. Toasting panko in butter creates a crunchy barrier. Let casserole rest 5 minutes before serving to allow sauce to thicken. For make-ahead: assemble completely (including toppings) up to 24 hours in advance, refrigerate, and add 5-10 minutes to baking time.
