"But for today, that is not why I'm here. I am here for the steak," she said.
Iowa, a small farming state of 3.1 million, holds disproportionate sway in US presidential politics due to its caucuses, which are the first-in-the-nation nominating event each election cycle.
The outcome serves as a bellwether for subsequent states' primaries and caucuses.
As a result, presidential candidates begin appearing in Iowa years before elections, courting local officials' support, building campaign infrastructure and boosting name recognition and reputation.
Clinton, 66, already has infrastructure for a possible presidential run practically in place, including key campaign figures and financial networks.
"I've got a few things on my mind these days," Clinton told the crowd, referring to the White House as well as the grandchild she is expecting from daughter Chelsea Clinton, in a speech that championed the middle class, women's health issues and equal pay.
Iowa is the state where on January 3, 2008, then senator Barack Obama scored his first victory against then senator Clinton, as both vied for the Democratic presidential nomination.
Obama gained 38 per cent of the Democratic vote, with Clinton finishing in third in a heavy blow.
"Well, it's been several years and a lot has changed," Clinton, who went on to serve as Obama's secretary of state, told the crowd of around 5,000.
"And let me tell you, he sure loves Iowa," Clinton added of Obama.
Clinton, who is also the former first lady, is polling far ahead of other potential Democratic contenders, including in Iowa.
Approximately 53 per cent of Democratic voters there favor Clinton, according to a CNN/ORC International poll released Friday. Vice President Joe Biden received 15 per cent of the vote.
