Casserole Premium Quality 1 lb Yellow Beans. The Casserole brand was founded in 1946 with the goal to bring high quality beans to consumers. Casserole beans are required to be light in color, tender, and have a short cooking time without soaking. If the beans meet our standards, they are cleaned to the greatest degree possible using the most modern of techniques. The cleaning process is not just a single step, but rather a number of sequences designed to remove all dirt, rocks, stems, leaves, and cracked or split beans as efficiently as possible. Finally, the beans are ready to be packed and shipped to a fine Walmart supermarket near you. They are peanut-free and tree nut-free. We hope you enjoy Casserole beans as much as we do!
