"Incredible night with friends and family!" she Tweeted, along with a selfie of the happy couple.
In an interview on KiroRadio with The Bachelor's Jason and Molly Mesnick on Friday, Hartsock, 27, said she was looking forward to partying at the DeLille Cellars winery in Woodinville, Wash.
"My parents are flying in from Ohio," she said. "There's about 40 people coming. I'm so excited."
The Mesnicks, who met on season 13 of The Bachelor, attended Saturday's event. "Celebrating the love of @DesHartsock & @ChrisRSiegfried this evening," Molly Tweeted. "BEAUTIFUL party...love these guys!"
Jason also posted a silly photo of his wife from the engagement party.
Hartsock and Siegfried, who will wed later this year, are enjoying wedding-planning mode. "We have little things planned," she said in the radio interview. "Now it's working on the bigger things!" Added Siegfried: "I'm somewhere in between hands off and highly involved. I'll offer my two cents. I just want it to be an awesome dance party."
The couple also talked to the Mesnicks about attending Sean Lowe and Catherine Giudici's live TV wedding in January.
Even though Hartsock was one of Lowe's Bachelorettes, she insisted that watching her ex tie the knot "was so not awkward," adding, "the wedding was a blast."
Siegfried admitted that being at the wedding gave them "a new perspective" on the idea of getting married on TV.
"We went in a little skeptical because we weren't sure what it was going to be like, but we're a lot more open to it now," he said.
