On its menus, Olive Garden describes the soups as "homemade" and claims that its many soups and sauces are made "the Italian way" — by hand, in-house, daily.
Additionally, alleged Olive Garden employees have shared detailed descriptions online of how things work in the kitchens and how the soups, in particular, are made.
A self-identified server on Quora said, "a large vat of each flavor is started very early in the morning, then vacuum sealed in large bags and kept in a warmer until needed."
One Redditor, a supposed former Olive Garden general manager, affirmed this theory, saying some ingredients may arrive frozen or pre-chopped, but the actual cooking happens onsite.
