"Back to Basics" peaked at #1 on the Billboard 200 and #2 on Billboard's Top R&B/Hip-Hop Albums chart.
It was certified platinum by the RIAA for shipments of one million copies in the United States.
On Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, "Back to Basics" received an average score of 69, which indicates "generally favorable reviews", based on 17 reviews.
Stephen Thomas Erlewine from AllMusic appreciated the album's production, commenting that the project was "all the more impressive" coming after the "near career suicide of Stripped."
Entertainment Weekly's Jody Rosen opined that Aguilera "can make her own glorious kind of 21st-century noise" and compared Aguilera's vocal ability on the album to that of Mariah Carey.
Mike Joseph of PopMatters felt that Aguilera "still shouts at times when a coo will do", but felt that her choice in collaborators made for an "ultimately rewarding listen".
Sputnikmusic's Amanda Murray noted the album as another "transitional" and "innovative" record for Aguilera.
Lucy Davies from BBC Music said that Aguilera has a "stunning voice", but stated that she could be more varied by cutting out some of the "y-e-e-eeeh, woah yeh's" on the second album.
Thomas Innskeep from Stylus Magazine preferred the first disc of the album over the "ridiculously overblown ballads" on the second disc, adding that "Back to Basics" was "one of 2006's best when Linda Perry's fingerprints aren't present".
Similarly, Yahoo! Music's Dan Gennoe described the first disc as a "low-down and dirty masterpiece", but said the second disc found Aguilera "crashing straight back down again".
Paul Flynn from The Observer provided a mixed review, saying that the beginning of the album was "all craft and very little heart"; however, he found the collaborations between her and Perry to be "deeply cinematic".
Rolling Stone's Jenny Eliscu opined that the release was "overindulgent and self-important", but would have been "masterful" had it been condensed into a single disc.
Kelefa Sanneh from The New York Times gave it a mixed review, stating that it "contains a roughly even number of great songs and lousy ones", and sait that "her homages to World War II-era pop music resemble skits more than songs".
Sal Cinquemani of Slant Magazine criticized Aguilera for using a sexual image to overshadow her vocals, but commented that the album was more "cohesive" than "Stripped".
Robert Christgau provided a negative review, classifying the album as a "dud."
