We like to use frozen lima beans in this recipe for their convenience, faster cooking time and bright color. However, it is also possible to use dried lima beans if you prefer. If you are using dried lima beans, you will need to soak them in water overnight or for at least 8 hours before cooking. Once ready to cook, drain the soaked lima beans, place them in a saucepan and cover with cool water. Bring to a boil, reduce heat and simmer until tender, about 30 to 45 minutes. This may seem like a lot of work for a side dish, but cooking the dried lima beans separately is necessary to ensure they are completely softened before adding them to the flavored oil. While frozen lima beans can simply be added to the pan, dried lima beans require that extra step of soaking and pre-cooking to achieve the right texture when simmered in olive oil and other ingredients. flavors.
