The Welsh mezzo-soprano announced on Monday that she had signed a three-album deal with Universal-owned Decca Records, the record company that helped launch her singing career 10 years ago.
Jenkins contract with record label, Warner Bros ended in 2013 at the end of a three-album deal.
“It’s a new year, and a new era,” said Jenkins, who was awarded an OBE in the New Year’s Honours.
“It feels not only very exciting but very special to be returning to Decca – a decade after they first signed me – and to many of the people who helped launch my career.”
She added: “It amazes me to think that will be my 10th album, and for this it seems the perfect place to be going ‘home’ to.”
At a launch event at London’s The Ritz hotel, Jenkins told reporters that her new album, due to be released in the autumn, would be a return to her roots.
“Over the years I’ve been able to experiment and try new things and through that process I know exactly who I am, what I want to do and what I don’t want to do.
“That’s why I feel that this 10th album will be a return to style of the earlier albums. If you enjoyed my first few albums then this is the album for you.”
Jenkins originally rose to fame with her debut release of Premiere in 2004 in which she blended classical songs and Welsh hymns, reaching number one in in the Classical Album chart.
Lamenting on 10 years in the music business, Jenkins said was glad she had heeded some words of advice when she had first started out.
“Someone said to me at the beginning – ‘stay true to yourself’. If you pretend to be something you’re not it’s going to be a really hard act to keep up.
“I’m so glad I listened to that. When you go to these photo shoots and someone says ‘lets try a sexier image’, [I know] that’s not really me.
“So you’ve got to know who you are and what you want because those images are going to be around for ever.”
Jenkins signed to Warner in 2008 in a three-album deal reported to be worth around £5.8m.
Her first two albums released under Warner – Believe and Daydream – both reached number six in the UK album chart.
Her last album, This is Christmas – released in December 2012 – peaked at number 26.
Last year, the singer took to Twitter to deny press reports that she had been dropped by Warner over “diva demands” and poor album sales.
