No, green pea soup and split pea soup are not the same. Green pea soup is typically made using fresh or frozen green peas, pureed or not, with other ingredients such as broth, cream, onions, garlic, and herbs. On the other hand, split pea soup is made using dried, divided peas that have been split in half rather than whole peas. The peas are simmered with other ingredients such as ham hocks, onions, carrots, and celery until they become tender and break into a thick, hearty soup.
