She co-produced Sugaregg with John Congleton and Graham Walsh, making it the first Bully album not to be solely produced by Bognanno.

[12] After having self-produced Bully's first two albums Feels Like (2015) and Losing, Bognanno decided to seek outside assistance in producing Sugaregg, as she felt that the quality of the music would be compromised if she continued to handle both songwriting and engineering duties by herself.

[11] She enlisted John Congleton to co-produce the album with her, while Graham Walsh of the band Holy Fuck provided additional production.

"[14] That summer, she recorded the bulk of the album in two weeks at Pachyderm Studios in Cannon Falls, Minnesota, accompanied by Congleton and backing musicians Zachary Dawes and Wesley Mitchell.

[16] She derived the album's title from an episode of the WNYC radio program Radiolab that profiled a man who preserved an egg-shaped mold of sugar, a keepsake from his childhood, for several decades.
