Description

My favorite casserole is green bean and mushroom. As a true Southerner, I understand the sacred role of casseroles in our culture. They’re more than just food – they’re vessels of comfort, marking life’s most significant moments. From welcoming new babies to saying goodbye at post-funeral gatherings, casseroles are our culinary storytellers.
