For this performance, New York Times reviewer Ben Brantley wrote that O'Hara "rockets past the promising ingénue status she attained with Light in the Piazza".[14]
She starred on Broadway as Billie Bendix in Nice Work If You Can Get It from April 2012 to March 2013 and received her fourth Tony Award nomination.[26] In 2012, at the New Year's Eve concert, "Celebrating Marvin Hamlisch", at Lincoln Center, she sang "At the Ballet", from A Chorus Line, along with Audra McDonald and Megan Hilty.[27] In 2013, she played the lead character of Julie in the staged concert of Carousel presented by the New York Philharmonic at Avery Fisher Hall.[28] From January to May 2014, she starred as Francesca Johnson in the Broadway musical The Bridges of Madison County, for which she received her fifth Tony Award nomination.[29] Elyse Sommer, the CurtainUp.com reviewer, noted O'Hara's "superb vocal chops" and her "exquisite" duets with co-star Steven Pasquale.[30] She played Mrs. Darling in the 2014 NBC telecast Peter Pan Live!.[31] She sang two concerts, titled Kelli and Matthew: Home for the Holidays, in December 2014 at Carnegie Hall with the New York Pops.[32] On December 31, 2014, O'Hara made her operatic debut at The Metropolitan Opera as Valencienne in Franz Lehár's The Merry Widow, alongside Renee Fleming in the title role.[33]

O'Hara returned to Lincoln Center Theatre to star as Anna Leonowens in the Broadway revival of The King and I opposite Ken Watanabe as The King. The production began previews at the Vivian Beaumont Theatre in March 2015 and opened in April 2015. This role won O'Hara her first Tony Award. O'Hara's final performance as Anna was in April 2016.[34] She gave her debut solo concert at Carnegie Hall in October 2016[35] and guest-starred as the recurring character Dody on the fourth season of Masters of Sex.[36] She played Fiona in the Encores! production of Brigadoon at New York City Center in November 2017.[37] Jeremy Gerard of Deadline Hollywood called O'Hara's performance "luminous", writing: "O’Hara is impossibly beautiful, vocally and in conveying Fiona’s romantic determination and heartbreak."[38] In 2017, she starred as Kate Bonner in the first season of the web drama series The Accidental Wolf,[39] earning a 2018 Primetime Emmy Award nomination.[40] O'Hara appeared in the 2018 season of 13 Reasons Why as Jackie, an anti-bullying advocate.[41] The same year at the Metropolitan Opera, she sang the role of Despina in Così fan tutte.[4][42] She reprised her role in The King and I at the London Palladium for a limited run from June to September 2018.[43]

The revival was produced by the Roundabout Theatre Company, which had produced a benefit concert of the show with O'Hara, Ellis, and Carlyle in 2016. O'Hara received her seventh Tony Award nomination for the revival.[44][45] In a 2022 interview with Theatermania, she discussed working on three projects at once: HBO's costume drama The Gilded Age, from Downton Abbey creator Julian Fellowes; a new season of The Accidental Wolf, in a role that earned her a 2018 Emmy nomination, as a woman who becomes embroiled in a scandal after receiving a phone call from a stranger being murdered; and a role in the operatic adaptation of Michael Cunningham's novel The Hours. She said "I love the fact that you have these things at the same time, because I don't ever want to be put in one box. I couldn't be happier or more challenged to have these three things happening at once."[46]
In May 2023, O'Hara originated the role of Kirsten Arnesen in the musical adaptation of Days of Wine and RosesOff-Broadway at the Linda Gross Theater. In September 2023, it was announced that Days of Wine and Roses would transfer to Broadway's Studio 54 with O'Hara attached. [47] Upon the show's January 2024 opening, a review in New York magazine noted: "O’Hara sings all but four of the play’s songs, and her voice is the kind of instrument that sends people scrabbling for metaphors. It’s a prism, an alpine stream, a Golden Snitch — clear, shimmering and darting, endlessly agile and controlled. She sings like Ginger Rogers dances."[48] The show, originally a limited run set to run until April 28th, closed early on March 31st.[49]

O'Hara is married to Greg Naughton of The Sweet Remains, son of actor James Naughton. Their first child, Owen James, was born in 2009.[50] Their daughter, Charlotte, was born in 2013.[51]
