Cajun Green Bean Casserole does Louisiana proud by staying authentic to its Creole roots! The holy trinity of celery, onion, and bell pepper makes its appearance, as does the zesty and spicy seasoning blend that makes New Orleans cooking so memorable! The crisp-tender green beans still have their garden freshness, which pairs beautifully with the succulent bacon, the spicy cream sauce, and the crunchy fried onion topping. You’ll never make traditional green bean casserole again after trying Cajun Green Bean Casserole, because the original just can’t compare with something this original!
