Concept and creation
The titular character, Steven, is roughly based on Sugar's younger brother Steven Sugar, who is now a background artist for the online web series, Bravest Warriors, created by Pendleton Ward of Adventure Time fame (he is also the background artist for Steven Universe as well). Growing up, Sugar would create miscellaneous comics between herself and Steven, as well as with other friends. In an interview with The New York Times, she commented on the development of the titular character's background, expressing her desire to base the character from the viewpoint of her brother growing up "where you're so comfortable in your life because you get all the attention, but you also want to rise up and not be the little brother." The show is set in the fictional Beach City, which is loosely based on Rehoboth Beach, Bethany Beach, and Dewey Beach, Delaware, all places that Sugar visited as a child.
According to Sugar, production began on the show concurrently while working on Adventure Time. Her last episode for the series was "Simon & Marcy", in which working on both simultaneously "became impossible to do". Similarly, she would encounter difficulty around the production of the episode "Fionna and Cake".
The series features songs and musical numbers produced by Sugar along with her story writers, who collaborate on the lyrics for each song. According to Sugar, not every episode will feature a song, instead opting to feature one every couple episodes "where it always feels right". The series premiere, "Gem Glow", features a rap song written by storyboard artist Jeff Liu, who programmed the beat into his Game Boy using Little Sound DJ. The soundtrack for all of the episodes is composed by Aivi & Surasshu with some demos by Jeff Liu.
The pilot episode for Steven Universe, along with a few other pilots, were released on Cartoon Network's video platform on May 21, 2013. They were taken down and redirected to a 404 page shortly after.  On July 20, 2013, Cartoon Network uploaded an edited version of the pilot to both their official website and Facebook page.  The pilots were also exhibited at the San Diego Comic-Con,  and from July 27 to July 28, 2013, Cartoon Network aired a sneak peek of the pilot as part of Big Fan Weekend, along with the pilots for Clarence and Uncle Grandpa. A 30-minute panel dedicated to the series was hosted at the New York Comic Con on October 13, 2013, with Rebecca Sugar hosting. The series premiered on November 4, 2013 on Cartoon Network, with two episodes. Season 1B ended on March 12, 2015, with Season 2 beginning on March 13, 2015. The latest episode was Season 2A, episode 57, "Reformed."
Initial announcements of the series have attained positive press for Sugar being the first female creator for any show produced by Cartoon Network Studios. When asked about her role as a solo female creator, she responded with gratitude towards the feedback, ultimately voicing her passion to be a role model "just in the sense that I get to make what the ultimate cartoon should be. I tried to be a role model [by showing that] anyone who wanted to could take really traditional ideas of animation and bring them into the present but keep all the trappings of what [was] used [to make cartoons great] in the past."
