A comforting and easy-to-make breakfast casserole using store-bought cinnamon rolls soaked overnight in a rich custard, perfect for busy mornings or special occasions.
Do not skip the overnight soak for best custard texture. Use room temperature eggs to avoid curdling. Grease the dish well to prevent sticking. Cover with foil during baking to keep moist. Adjust baking time if casserole is too soggy or dry.
