"Fergalicious" was written by will.i.am and Fergie, credited as Will Adams and Stacy Ferguson respectively. The song contains samples of "Supersonic" by J. J. Fad and "Give It All You Got" by Afro-Rican. The writers of these two songs, Dania Maria Birks, Juana Michelle Burns, Juanita A. Lee, Kim Nazel, Fatima Shaheed, and Derrick Rahming, receive songwriting credits for "Fergalicious" as a result. The song was recorded while on the John Lennon Educational Tour Bus. While discussing the tracks on the album, will.i.am had this to say about the song, "... but then she'll have a song like 'Fergalicious,' where it's just being sassy and flaunting her stuff from a strong female perspective, paying homage to Salt-N-Pepa." will.i.am produced the song as well as playing the bass, keys and drum programming. He collaborated with Padraic Kerin on engineering the track while John Hanes edited it through the use of Pro Tools. Serban Ghenea worked with Tim Roberts on mixing the song, which took place at MixStar Studios in Virginia Beach, Virginia. A&M Records, in association with will.i.am Music Group and Interscope Records, sent the song to contemporary hit radio on October 23, 2006. Fergie stated in an interview with MTV that the song reminds her of the old days, when "I went to Knott's Berry Farm [in California] and did what I thought was a dance battle."
"Fergalicious" is an electro, hip hop and dance song with a length of 4:52 (4 minutes and 52 seconds). The song features sampling from two songs, "Supersonic" by J. J. Fad and "Give It All You Got" by Afro-Rican, utilizing their rapping style and synthesized strings respectively. The song is set in common time and has a moderate hip-hop tempo of 112 beats per minute. It is written in the key of B-flat minor and Fergie's vocals span two octaves, from G3 to D5. "Fergalicious" begins with a countdown in two different languages, English and Spanish. The song then moves to a fast-paced rhythm and a synth line referencing Kraftwerk's "It's More Fun to Compute", as will.i.am raps. The rhythm transitions into "pong" basslines over which Fergie raps with "detached nonchalance". The song features an interlude that runs in a jingle style.
The lyrics are centered on the theme of self-pride. Fergie raps about how she bests all other women and that no other man is worthy enough to date her. Leah Greenblatt of Entertainment Weekly describes the song as a "self-love anthem". Sal Cinquemani of Slant Magazine wrote that the song "opens The Dutchess with a cartoonish Black Eyed Peas tone". According to Kelly Smith of The Maneater, the song is a "rap remix that consists of a catchy chorus and cheesy lyrics."
"Fergalicious" received generally positive reviews for music critics. Bill Lamb of About.com rated it four out of five stars, liking better than the previous single "London Bridge" which he found "reaked of sleaze". He praised the song as "a sassy, fluffy party tune that should be lighting up pop radio within weeks." Leah Greenblatt of Entertainment Weekly writes that the song does not stray away from her previous works with the Black Eyed Peas, comparing the lyrics to those of "My Humps". Norman Mayers of Prefix thought it and "Here I Come" are fun and flirty songs, writing that "they work because of the dance-floor productions that not only reference '80s hip-hop but also '60s Motown." Dan Gennoe of Yahoo! Music described the song as "booty-shaking electro". Louis Tullo of The Heights writes that "the result [of the song] yields danceable beats and playfully salacious lyrics, but it seems her voice is lost in overproduction." Kelly Smith of The Maneater thought that the song would be successful on the radio, writing "this song will most likely become a radio whore, being played over and over until people are forced to admit that the beat is so-so." Eva Wiseman of The Guardian praised the song as "joyous and fabulous pop music, the kind of people who mop up silently when she wets herself on stage... It even inspires blasphemy in critics."IGN writer Spence D. finds "Fergalicious" to be a nice start up for the album, referring to the song as "an infectious little ditty that grinds its way into your grey matter with unavoidable tenacity."

The music video was filmed in Hollywood, and directed by Fatima Robinson, who also directed the "My Humps" music video. will.i.am from The Black Eyed Peas also appears in the video, which features Fergie as Willy Wonka in a candy factory called "Fergieland" (the factory was nameless in the original book and both film versions).

Throughout the video, she wears a tan and khaki girl scout outfit, sports a black one-piece swimsuit while lying in a pile of candy, (often in a kaleidoscope view) works out in a colorful gym flexing her biceps, sings in a room filled with lollipops and other candies while dressed like Shirley Temple, and pops out of a cake while wearing a tiny blue swimsuit with gems encrusted on the exterior. She then starts watching two women wrestle in cake before joining them at the end of the video. Towards the end of the video, Fergie opens and then plays a few notes on a Samsung K5 MP3 Player, giving it center focus in the screen; there then follow, interspersed in the remaining frames of the videos, shots of other characters in the video either listening to the player, presenting it to the camera with a big smile, or carefully handing the player to another extra. As of November 11, 2013, the music video for "Fergalicious" has been viewed over 50 million times on popular video-sharing website, YouTube.
In March 2009, former N.W.A member the Arabian Prince sued Fergie's record label over unpaid royalties for including a sample of Supersonic, a song he produced, for Fergalicious. The lawsuit was filed in the New York Supreme Court, claiming that Tamika Wright, Jerry Heller and Ruthless Records owed him 20% of the royalties from the song.
