In 2003, Darling made her name first known to the public when she was a top-three finalist on E! Entertainment Television's reality show The Entertainer, hosted by Wayne Newton. She missed out on winning the show as Newton believed she was not right for Las Vegas and he advised her to head to Nashville to focus on country music. Sarah Darling went into the studio in the summer of 2008 to record her debut album, Every Monday Morning, which was released on June 16, 2009. Her single "Jack of Hearts" successfully made its debut on Country Music Television's top 20 countdown. A second album, Angels & Devils, was released on February 15, 2011, following its lead single "Something to Do With Your Hands" and a digital single release of the U2 cover "With or Without You". To promote the single, Black River Music Group arranged for Darling to sing the national anthem for a Buffalo Sabres game in place of usual singer Doug Allen; the Sabres and Black River are both owned by Terrence Pegula. In late 2012, a new single titled "Home to Me," was released to digital retailers on August 21, 2012 after being previously featured on Sirius XM's The Highway country-music station. It sold over 8,000 copies in the first week of release becoming the top selling digital single from a new female artist since May 2011 when Lauren Alaina released "Like My Mother Does". "Home to Me" became Darling's first single to chart on the U.S. BillboardHot Country Songs chart, reaching a peak of number 34. "Home To Me" was issued to radio, in multiple versions, customized for different states. However, after releasing a digital EP, Home to Me, on January 29, 2013, Darling and Black River Entertainment parted ways. Darling released "Little Umbrellas," independently on June 4, 2013 to digital retailers. It was also issued to country radio on June 24, 2013, though it failed to chart. Darling has been featured on TBS' CONAN, FOX & Friends, HLN Morning Express with Robin Meade, ABC's The Bachelor, Better TV and many additional news outlets. She wrote the song "Knowing What I Know About Heaven," which was recorded and released by Guy Penrod, and has a passion for baking. Darling was a contestant on ABC's Rising Star first season in 2014, and was eliminated in the fourth week. However, after her elimination Brad Paisley, one of the show's judges, invited Darling to perform with him at the Grand Ole Opry. On February 10, 2017, Darling self-released her Dream Country album, a compilation of songs that provided a glimpse into her new musical direction. Dream Country was well received in both the US and UK with over 4 million streams on Spotify and Apple Music. In 2016, 2017, 2018 and 2019, Darling performed at the festival, the largest country music event in Europe. On February 20, 2018, Darling teased her new single "Wasted" ahead of an upcoming tour in the UK and Ireland. On June 7, 2019, Darling released her newest album Wonderland which climbed to the top of the official UK Country Artist Album Charts.
