On 15 November 2005, to celebrate Lyngstad's 60th birthday, [[Universal Records]] released the box set ''[[Frida: 4×CD 1×DVD]]'', consisting of all the solo albums she recorded for [[Polar Music]] and Anderson Records, including a set of bonus tracks. Also included was ''[[Frida: The DVD]]'', a 3.5-hour documentary where Lyngstad talks about her entire career in the music business. Filmed in the Swiss Alps, she talks about her singing technique and about her career both before and after ABBA, and explains how songs were performed and recorded. In collaboration with Swedish TV, [[Sveriges Television|SVT]], the film included many clips from her early television performances, such as her first TV performance with "''En ledig dag''" ("A Day Off"). Also included are TV documentaries about the making and recordings of ''[[Something's Going On]]'' and ''[[Djupa andetag]]'' ("Deep Breaths").

In 2007, Lyngstad became one of the initial patrons of the Zermatt Unplugged Music Festival along with Jon Lord and Claude Nobs. 

In September 2010, a new album by musician [[Georg Wadenius]] titled ''Reconnection'' was released. Lyngstad and Wadenius had discussed working together for many years, as they had long been good friends. The album opens with her rendition of the traditional tune "[[Morning Has Broken]]", previously covered by [[Cat Stevens]]. This song is a favourite for Frida and the song was also on the playlist in the church for Frida and Prince Ruzzo's wedding on 26 August 1992.

On 16 February 2011, BBC Radio 4 broadcast a 45-minute play featuring Lyngstad and the play's writer, long-term fan and performer [[Christopher Green (writer-performer)|Christopher Green]]. The play, ''Like an Angel Passing Through My Room'', was billed as "a story about love. The unconditional love of a devoted fan&nbsp;... about a real and an imagined intimacy." It was a project several years in the making; what started as an upbeat reflection on fame and  being a fan developed into a meditation on the communication between two people and coping with the blows life deals. In an interview, she and Green talked about her long recovery following the death of her husband in 1999. The play is reflective but with a comic sensibility. Lyngstad stated in 2004 that she never intended to return to the music industry, although this was short-lived, and future studio albums were discussed in 2010.

In 2013, she helped organise the opening of [[ABBA The Museum]] in Stockholm stating she wanted to "let ABBA rest". The long-awaited ABBA reunion was expected to happen in 2014 to celebrate the 40th anniversary of the group's win at the [[Eurovision Song Contest]]. However, this did not happen. In 2015, Lyngstad, along with Dan Daniell, released the single "1865" about the [[Matterhorn]] in Switzerland.

In the summer of 2017, Lyngstad joined her ABBA bandmates Agnetha Faltskög, Björn Ulvaeus and Benny Andersson to record two new songs, "[[I Still Have Faith in You]]" and "[[Don't Shut Me Down]]". These songs were meant to be part of an ABBA-themed TV special that was eventually discarded and replaced by the more ambitious, digital-laden ''Voyage'' show. 

In 2018, Lyngstad and jazz trumpeter [[Arturo Sandoval]] released a duet of the ABBA song "[[Andante, Andante]]" as a single. The song is featured on Sandoval's album ''[[Ultimate Duets]]''.

On 2 September 2021, via YouTube livestream, ABBA announced their upcoming [[virtual concert|virtual]] [[concert residency]]  "[[ABBA Voyage]]", as well as the imminent release of an eponymous album, recorded between 2017 and 2021. The new record, their first studio album in 40 years, features ten tracks, including "I Still Have Faith In You" and "Don't Shut Me Down", which also were first shown in the aforementioned livestream event and released as a double A-side single. On 5 November 2021, the ''[[Voyage (ABBA album)|Voyage]]'' album was released worldwide. On 27 May 2022, ABBA Voyage opened in a purpose-built venue named the ABBA Arena at the [[Queen Elizabeth Olympic Park]] in London.
