What exactly do you find in a fandom that's grown around a book that makes the Apocalypse hilarious? Well, Slash Fic, for one, and also plenty of Continuation Fic. A Second Apocalypse is usually optional, although not unheard-of (as you'll see in the recs below).
But mostly slash.
Before you run away screaming, keep in mind that this article is part of an attempt to collect the 10% of fanfic that's worth dying for. That means that every story on here was recced because of its high quality and in-character depictions, including (and sometimes especially) the slash.
These are recommendations made by Tropers for Good Omens fanfic, all of which have to be signed to stay on the page. You can also add to the current list of recommendations if you want, but please remember to use the template found here.

Comments: The best Aziraphale/Crowley writer I know of, this author also writes superb gen fic (relating to the Them, Adam and Pepper in particular; however, she's written a few amazing Shadwell/Tracy and Shadwell-centric pieces, too). She also occasionally crosses GO with other fandoms (notably Hot Fuzz and Sherlock). Everyone is unbelievably in-character, but her Crowley-POV pieces may shine brightest.
(Thank you for the kind recommendations, everyone, all throughout these threads. Having never edited this page before, I'd just like to add a note that the entirety of Crown of Thorns 'Verse is now available on AO3; henceforth, that'll update when LJ updates. Otherwise, there's now a full directory of the rest of my GO drabbles, ficlets, and stories spanning the past almost-decade here. ~ irisbleufic)
Comments: A keen sense of history, an excellent ear for dialogue, and an unbelievable proclivity for making Crack Fic work. Although many of this writer's pieces are listed as Aziraphale/Crowley, the grand majority of them can be read as gen (if you want a rare exception, see here for an untitled explicit ficlet). More specific recs are given below in the General Fic section (Going Home and the WWI Series).
Comments: Most works focus on Aziraphale/Crowley, with varying degrees of explicit content (many can be read as gen). In addition to both lyrical prose and a biting sense of humor, you'll find impeccable historical research and a delicate combination of lightness and subtlety in the dialogue. Similar to irisbleufic, expect a mature, defined individual style that's quite different from the one used in canon, but characterization that is almost always right up to spec, which, in my book, counts far more than the ability to mimic the authors' style.
Comments: This writer doesn't appear to be all that active anymore (much like daegaer), and while most of her pieces are very short drabbles, ficlets, and snippets, you'll find the occasional slightly longer piece. Not necessarily as polished or as distinctive in style as those previously mentioned, but her characterization is quite good, and her Aziraphale/Crowley smut tends to be both witty and sweet.
Pairing(s): Aziraphale/Crowley (sometimes gen, sometimes slash)
Comments: Saying these are funny is like saying that the original book has a slightly lighter approach to the Apocalypse. Even the shamelessly smutty fic is far more hilarious than Porn Without Plot have any right to be. Quantum Witch has illustrated some of Bender's fic for even more comedic goodness. Be forewarned: even the gen ones are packed with Ho Yay that barely stops short of actual slash.
Pairing(s): Aziraphale/Crowley with the occasional mixup
Comments: Do you like slash? Do you like some smut with your slash? Do you like your slash to be ridiculously well-written, fascinatingly historical, and droolingly hot? Then look no further! Vulgarweed is an amazing author who is still active in the fandom, and even better, she coordinates a lot with Quantum Witch, who (as she did for H.J. Bender) illustrated some fic too. Enthusiastically recommended!
Summary: Other people plan 100 things to do before they die. Crowley planned 100 things before EVERYBODY died.
Comments: Exactly what it says on the tin, except not. What starts out as a humourous and light-hearted series of loosely connected drabbles quicky progresses into a poignant, thoughtful, touching plot involving trust, bad decisions and the Second Apocalypse. The writing is phenomenally in-character and follows very believably from where Aziraphale and Crowley left off in the book.
Summary: When a not-too-bright dogfish swallows a wishing ring and causes mayhem with his careless wishes, a restless Horseperson sees a great opportunity, and only an angel and demon can restore things back to their natural order.
Comments: Has an entertainingly original plot guaranteed to leave you grinning.
Summary: Aziraphale takes Death's place for a day upon God's request.
Comments: A rare Aziraphale-centric story that does him justice. Has a non-Original Flavor prose (me pointing out that a fic's "great, but not in the style of canon" is my Single Issue Wonk, so don't let that deter you) that manages to be atmospheric without a whiff of Purple Prose or Pacing Problems, inspired characterizations of God, Lucifer, and Beelzebub, and themes about divinity and death that avoid Anviliciousness.
Summary: In the Middle East, during the 11th century and its Crusades, Aziraphale and Crowley first come to their Arrangement.
Comments: One of the few fics about the start of the Arrangement, and by God, the author does it justice. The characterisation stays top-notch throughout the fic, even though these are Aziraphale and Crowley as you've never seen them before, worn out by the horrors of humanity and unsavoury orders from their superiors, desperate for company but still wary about trusting each other. The plot is equal parts angst and heartwarming and fits right in with the book's canon. The author's other (often illustrated!) works are well worth checking out as well.
Summary: Aziraphale is recalled to Heaven, and Crowley isn't happy about it. After offing Aziraphale's Replacement Scrappy in a variety of amusing ways, he enacts a Heaven-contacting ritual that goes wrong in all the right ways.
Comments: I've already recommended daegaer's stories above, but this fic deserves special mention as a work that pulls off the common "Aziraphale and/or Crowley are recalled by their superiors" plot brilliantly without descending into melodrama. You won't find any angst here: just light-hearted, humorous drama that's surprisingly poignant in showing how much Aziraphale and Crowley mean to each other.
Summary: Of course everyone knew there would be consequences, and that the world would have to end sometime. A story about What Happened After, with guest appearances by Him Below, the four Archangels and the Big Cahuna Himself.
Comments: Covers the "What do we do now?" aspect of the end of the book very well. Characterizes the relationship between Aziraphale and Crowley beautifully, and offers some really memorable characterizations of Lucifer, the Archangels, and God.
Pairing(s): Newt/Anathema, Crowley/Aziraphale, Brian/Pepper, Adam/OC, and some other relationships between OCs
Summary: The end of the world has failed to happen, but things aren't going to settle back down anytime soon. Anathema's expecting, the Antichrist's about to enter puberty, an angel and demon find themselves irretrivably in a Romance Arc, the Seven Deadly Sins awaken, and the Second Coming of Christ draws nigh.
Comments: Like the original book, this Continuation Fic introduces several unique subplots, takes care to develop each of them with their own twists and surprises, and eventually draws all of them together at the climax to form a satisfying conclusion. Best of all, even when it takes the canon material into creative directions, it remains lovingly faithful to the established canon characters and relationships. The end result truly reads as a sequel to the original book.
Addendum by L Guardinal: (Most of) Quantum Witch's other works are quite good as well (though the vast majority, if not all of them, are Crowley/Aziraphale, sometimes quite explict, so read at your own risk). They can be found at The Good Omens Library.
Pairing(s): Implied Aziraphale/Crowley at the end, easy to miss.
Summary: A series of vignettes about how significant historical events affect Aziraphale and Crowley over the years.
Comments: This story may not be as original-flavored as other stories (stylistically speaking), but it's got a smooth, lyrical feel to it that captures the characters' raw emotions and relationship developments without having to say them out loud.
Summary: Crowley's still suffering from survivor's guilt. Fortunately, Aziraphale is there to help him through it.
Comments: The focus this time is on Aziraphale and Crowley's relationship and personal lives, in deliberate contrast to the epic, history-changing events of Survivors' Guilt. Despite the different focus, it retains the same lyrical quality and emotional depth, making even the sexual references seem somehow clean and in-character instead of giving off that "dirty" vibe.
Summary: Aziraphale and Crowley move into that cottage together in the South Downs. Cue neighbors and other locals treating them like a couple, fawning over their pet-names for each other, and generally believing them to be life-partners. Eventually, they just decide that, really, they've technically been dating for six thousand years and might as well give it a go. Crowley's characteristic vulnerability is spot-on.
Comments: An adorable and fluffy story, unlike most of irisbleu's other fic. The characterization is especially good - Aziraphale and Crowley have an incredibly sweet relationship, and the OCs are brilliantly written (yes, even the mouse!)
This story (along with A Better Place, which was actually written well before it) is by now the starting point for an ongoing series. See here for a full directory of links to the stories and ficlets in it. -Kelliannm
Pairing(s): Aziraphale/Crowley, otherwise featuring five insignificant (yet crucial) original characters.
Summary: Aziraphale and Crowley as seen through the eyes of others (more specifically: humans) in the places they live and frequent around London (Mayfair, Soho, The Ritz, Bloomsbury, and - of course - St. James's Park).
Comments: This is brilliant from start to finish, especially the original characters. You'll never look at them quite the same way again, by which I mean, you'll recognize them for exactly who they are, but with an added appreciation thanks to the outside viewpoints.
Summary: Aziraphale and Crowley are invited to a fancy dress cocktail party, but it's so much more than that. This story operates under the assumption that Aziraphale has never seen Crowley's eyes in all this time (not a spoiler; author gives that piece of information at the start).
Comments: Although it's difficult to believe that Aziraphale wouldn't have seen Crowley's eyes in six thousand years' time (presumably he did see them in Eden), suspend your disbelief for a moment and read this amazing little one-shot. Amongst other things, it's the only fic besides irisbleufic's The Walls, the Wainscot, and the Mouse universe that takes up the South Downs cottage premise that I can find.
Summary: A remix of Daegaer's AU ficOrdinary People that takes the original's basic concepts and ties them back to canon.
Comments: The Slice of Life events and gradually developing romance are done gracefully without ever losing sight of the fact that Crowley and Aziraphale are ethereal beings who, while being the most "ordinary" of their kind, are still anything but ordinary compared to humans.
The original AU fanfic must be recommended as well, as the author's depiction of what Aziraphale and Crowley would be like as humans makes for wonderfully interesting characters. This Troper would advise you to read the AU first and then the remix.
Completely and utterly seconded, and it stands alone very well even without the original. Utterly touching, beautiful, believable take on a Relationship Upgrade, with flawless prose and characterisation throughout.
Summary: Aziraphale and Crowley pay a visit to Adam eleven years after the Incident, presumably only to see how he's doing. But it's really more than that, and has to do with the New Arrangement formed during their trip to America.
Comments: Has the most perfect Original Flavor writing in the GO fandom, hands down. Crowley and Aziraphale are as entertaining as ever, Adam and the rest of Them have much-welcomed appearances, plenty of lines are giggle-inducing, and the progression of the main relationship over these eleven years is very much in-character and gives you a case of the warm fuzzies, especially at the closing lines.
Summary: The world is fine, but Aziraphale and Crowley are still tense and anxious. Aziraphale suggests to Crowley that they check with their superiors for peace of mind. Unfortunately, they don't know the full details of portal-opening...
Comments: A satisfyingly long work that answers the So What Do We Do Now? question facing Aziraphale and Crowley at the end of GO canon. How the two beings cope with their anxieties in the wake of the Apocalypse That Wasn't are dealt with thoughtfully without ever descending into wangst. Even their eventual Relationship Upgrade is done in an in-character manner that doesn't need big declarations.
Summary: Crowley's new hobby is seeing how long other fish survive against his pet fish, The Great White Bastard. Aziraphale drops by in time to witness this. There's toasting to the number of fish killed, and talk about a woman who's being driven mad by her divine sight and a previous experience in a whorehouse. Then there are kisses and merging.
Comments: One of those stories that can't be described without sounding like Crack Fic or a Mind Screw. Initially appears to be nothing more than a silly, nonsensical drunken conversation between Aziraphale and Crowley, then morphs halfway into something achingly beautiful.
Seconded like heaven and hell. This is nothing like the "close friendship, just add sex" model most slash fic takes in getting the characters to get together, no. This shows the creation of a love that actually convincingly looks like it could outlast empires.
Pairing(s): Aziraphale/Crowley, Newt/Anathema, implied Adam/Pepper and Adam/Harry
Summary: Hell hasn't given up after the Apocalypse That Wasn't, and formulates a new plan involving the wizarding world. Characters from Harry Potter make appearances, though it's not so much a proper crossover as it's an Original FlavorGO fic with the Harry Potter extras.
Comments: Details the second coming of the Apocalypse so perfectly in-tune with the canon style and characters that it feels like you're meeting and becoming enthralled with the original characters all over again. And yes, the Harry Potter characters are IC too.
Summary: Pepper's all grown up, but she's restless about her life until she meets a certain Horseperson who has something eating away at her that she can't name. Somehow, the two give each other what they're looking for.
Comments: Makes the Crack Pairing work beautifully by showing how the two redheads' personalities attract and play off on each other, and how humanity might just be affecting War as it did a certain angel and demon.
RainKrystal: The prose here is just attractive, I don't know how else to describe it. There's just something about this fic that just sucks you right into it and makes you believe that this truly, awfully cracked-out pairing is actually possible.
baywoof: Wow. The writing is great, and it's amazing how convincing Pepper/War is.
Comments: Excellently written in Original Flavor, but with a twisted undercurrent to it; this is what Good Omens would have been like if processed through a nightmarish filter of cynicism. It's the kind of fic you read through once for the great writing, then vow to never read again after being left a broken, sobbing heap at the end. As awesome as the twists and reinterpretations are, it's definitely not a fic for easy reading.
Summary: Aziraphale can't sit on fences, and Crowley wants the third side.
Comments: Proof that a fanfic doesn't have to be of epic length to be funny, romantic, and thoughtful at the same time. Done with excellent footnotes, a precise blend of the silly and the serious, and Aziraphale/Crowley interaction that's just understated enough to work.
Summary: Crowley's been given a birthday from Down Below, and he wants to be distracted from the related memories of his Fall. That's when Aziraphale shows up, intent on chewing him out for what he did when drunk some time before. Things do not go as either anticipated.
Comments: This fic is a lemon with explicit m/m action. That said, it's a lemon done right. Neither Aziraphale nor Crowley are derailed into more "appropriate" roles or given corny romantic lines. The plot doesn't throw them into bed right off the bat, allowing them to set their own pace. Even in the midst of the "action" scenes, the characters' quirks and natures (especially the fact that they're not trulyhuman) aren't forgotten, thus avoiding the feel of everything else in the story serving as nothing but a clothesline for the smut.
Summary: Armageddon comes around again and Aziraphale and Crowley can't escape it this time.
Comments: The aftermath for Aziraphale and Crowley, for whom Earth felt more like home than Heaven or Hell ever did, is dealt with in a manner neither preachy or melodramatic but humorous and sneakily serious in a very canonesque way. Really, that's the best way to describe a fic with two opening quotes, one from Paradise Lost and one from a rock band, that can both be used to sum up the story. (Plus, the slash's well-integrated and the story arguably wouldn't be as emotionally powerful without it.)
Summary: Crowley and Aziraphale are given new assignments to tempt / redeem each other to the other side. Though it is actually a set up by both sides looking to scapegoat someone for the failed apocalypse.
Summary: Nothing lasts forever and the final Apocalypse can only be delayed for so long. There is a school of thought that says you cannot fight fate. And another that claims there's no such thing as predestination, only those powerful enough to make your choices for you - if you let them. Aziraphale puts both to the test.
Comments: Manages to make your heart shatter into itty-bitty pieces while still giving you a lot of food for thought on ineffable games of Solitaire. The characterisation is intriguing and the fics will stay with you for a long time.
Summary: A capture, a ritual, and a small mistake in terms lets Sam and Dean become 'sacrifices' to another demon with yellow eyes. Things don't exactly end how you might expect them to. Crossover with Supernatural.
Comments: Brilliantly written in a style that sounds just like Pratchett and Gaiman. Everyone is in-character and it's absolutely hilarious.
Seconded by cg12345. Style is spot-on, and Aziraphale is shockingly badass at the climax. Beware the Nice Ones, indeed.
Summary: Team Free Will meets everyone's favourite angel and demon, and it all spirals from there.
Comments: One of the best Supernatural/Good Omens crossovers out there, in my opinion. There is a lot of shipping in this one, but the deep exploration of the relationships between Aziraphale and Crowley, Sam and Gabriel, and Dean and Castiel is what really makes the fic work. The scenes in this fic range from jaw-droppingly awesome to downrightheartbreaking, and the interaction between all the characters is vivid and believable. Deserves its own trope page, I think.
Seconded, seconded, a million times seconded by RainKrystal. This fic is one of the bestGO stories I've read in a while, and even though I was never a fan of Supernatural before I read this, I am one now. The story is good, but what drives it up to the epic level is that mixed in with all the action and the awesome are these incredibly personal, character driven moments that make your chest ache when you realize you've been holding your breath. The characters make the plot go, and it goes where's it's going at a good pace.
This author has also written a number of other Good Omens/Supernatural stories, some of which are tremendously funny, others heart-wrenching (and sometimes both at once), but all of which feature amazing characterisation and excellent writing.
