Peck's first novel, Martin and John, was published in 1993. His subsequent work, which continued to explore issues of identity and sexuality, were met with more mixed reviews. Salon.com described Now It's Time to Say Goodbye as a "hyperpotboiler" with a plot "both sensational and preposterous." The New York Review of Books called Martin and John "surprisingly sophisticated", but said Now It's Time to Say Goodbye "collapsed under the weight of its overladen allegorical structures" and diagnosed Peck's fiction as a "seesaw between a strained 'lyricism'... and cliché." Peck has also drawn attention as a critic. His reviews for The New Republic, while establishing him as one of the most influential commentators on books, also garnered the opprobrium of the literary establishment for their negative treatment of some of the most highly regarded writers at the time, but also their underlying questioning of what would be the larger project of turn-of-the-century American letters. His most notorious line, "Rick Moody is the worst writer of his generation," set the tone for a collection of essays published under the title Hatchet Jobs. In 1996, Peck reviewed the David Foster Wallacebest-selling novel Infinite Jest, writing that "hat makes the book’s success even more noteworthy is that it is, in a word, terrible. Other words I might use include bloated, boring, gratuitous, and – perhaps especially – uncontrolled. I would, in fact, go so far as to say that Infinite Jest is one of the very few novels for which the phrase ‘not worth the paper it’s written on’ has real meaning in at least an ecological sense." Peck, in the same article, also attacked American writersJonathan Franzen, Don DeLillo, and Thomas Pynchon, characterizing the latter as "a very clever guy" and his prose as "tentacular – I might almost say...amorphous." Peck's reviews, in turn, were met with criticism, with the editors of Brooklyn-based n+1 magazine, though stating, in 2004, that
With the emergence of the ridiculous Dale Peck, the method of Wieseltier's literary salon reached its reductio ad absurdum. Peck smeared the walls with shit, and bankrupted their authority for all time to come. So many forms of extremism turn into their opposite at the terminal stage. Thus The New Republics supposed brief for dry, austere, high-literary value—manifesting itself for years in a baffled rage against everything new or confusing—led to Peck's auto-therapeutic wetness and hatred of classic modernism.
In May 2011, Peck's criticism of Jewish American literature in which he claimed "f I have to read another book about the Holocaust, I'll kill a Jew myself" prompted a public outcry. His editors later removed the statement from his article. In 2016, Peck was named editor-in-chief of the revived online Evergreen Review. "I want the magazine to be something between a community and a place where lone wolves hang out," Peck said at the site's launch in March 2017. "I have a preference for experimental literature, but for genuinely experimental literature as opposed to literature that says it is experimental but it is really just repeating someone else’s experiment from 70 years ago. All good literature is experimental, at least in the sense that it invents its own terms." In 2019, Peck wrote an article published by The New Republic titled "My Mayor Pete Problem," referring to Democratic presidential candidatePete Buttigieg, which, though its views were supported in a Spectator column, was subsequently criticized as homophobic. The New Republic pulled the article after hours online. Editor Chris Lehmann stated, "The New Republic recognizes that this post crossed a line, and while it was largely intended as satire, it was inappropriate and invasive." Peck teaches creative writing at The New School in New York City. He is also a columnist for Out.
