Judges Paul Hollywood and Prue Leith voted for the teacher from Cambridgeshire, 28, after a final task involving a choux pastry signature.
“I don’t know what to say. Everyone said you should go on Bake Off and I thought it was a throwaway comment and never really listened to it," Edgell told presenter Alison Hammond.
The PE and science teacher said he felt like an "underdog" during the series and never expected to win. He beat 12 culinary hopefuls who entered the competition back in September.
Edgell will now be hoping to follow in the footsteps of some of the previous success stories from the popular series. Some past winners of the show, which is broadcast on Channel 4 after first being shown on BBC Two when it started in 2010, have brought out their own cookbooks.
Here's what all the past winners have been up to since becoming the kings and queens of British TV's most famous kitchen.
Edd Kimber (2010)
Kimber was the first winner of Bake Off all the way back in 2010.
After his landmark win, he ended his career as a debt collector to become a full-time food writer and has released three cookbooks: Say It With Cake, The Boy Who Bakes and Patisserie Made Simple.
The multi-talented Kimber is also the host of the popular podcast Stir The Pot, and was the baker on The Alan Titchmarsh Show in 2014.
Reflecting on his GBBO success last year, he said: “When the finale aired, I still remember people applauding the idea that a man could win a baking show.”
Jo Wheatley (2011)
Wheatley took the Bake Off crown following an all-female final and has gone on to release two bestselling cookery books, A Passion for Baking and Home Baking.
The mum of three, 49, has also appeared on The One Show and The Alan Titchmarsh show and has written for the Sun and Sainsbury's Magazine.
She now plans to open her own cafe, country pub and restaurant.
John Whaite (2012)
John Whaite won the third series of Bake Off when he was only 23 and still studying for his law exams.
These days, he prefers cooking to legal affairs. He has had four recipe books published: John Whaite Bakes, John Whaite Bakes at Home, Perfect Plates in 5 Ingredients, and Comfort: Food to Soothe the Soul.
Whaite has also proved his mettle on the dancefloor, finishing runner-up on the BBC show Strictly Come Dancing in 2021 with his male dance partner Johannes Radebe.
Frances Quinn (2013)
Qunn shocked everyone when she beat the favourite Ruby Tandoh to the title in 2013.
Since then, she has pressed pause on her career as a children’s designer and immersed herself in the cooking world. She has released her own cookbook, Quintessential Baking, for example.
Quinn has baked for many British celebrities, including Jools Holland and Clare Balding, and was the mastermind behind the cake for The Shard's first anniversary.
She has also appeared on Pointless Celebrities and in Vogue magazine in 2016.
Nancy Birtwhistle (2014)
Birtwhistle brought a smile to everyone’s faces when she unexpectedly emerged as the winner of Bake Off series 7.
The retired GP practice manager and grandmother of eight has released her own book. She also writes regularly for the Daily Telegraph as well as her own website
In her spare time, Birtwhistle campaigns for the charity Love Food Hate Waste.
Nadiya Hussain (2015)
Hussain was truly the people's favourite when she left the Bake Off tent victorious in 2015.
She has had an incredibly successful career since, writing for national newspapers, releasing her own cookbook, and presenting ITV's Loose Women.
She has also hosted her own TV programmes: The Chronicles of Nadiya, Nadiya's British Food Adventure, The Big Family Cooking Showdown, and Nadiya's Family Favourites.
A career highlight for her was when she was chosen to bake a cake for Queen Elizabeth's 90th birthday. She was named as an MBE in the New Year Honours List in December 2019.
Candice Brown (2016)
Brown was famed for her ever-changing lipstick colours while on the show — and her career has certainly evolved in a similar vein.
She has released her own recipe book, Comfort: Delicious Bakes and Family Treats, and writes a column for the Sunday Times.
She has also appeared on Loose Women and been a contestant on ITV's Dancing on Ice—– although she didn't fare as well on this reality TV show after being booted off first.
Brown got hitched to fiance Matt Macauley in September 2018. However, the couple confirmed in the summer that they had split up.
Sophie Faldo (2017)
Faldo famously claimed the Bake Off title prematurely when Prue Leith accidentally tweeted the winner hours before the show was broadcast.
As well as making regular baking appearances, the first Channel 4 champ is also a track cyclist and rower and is training to be a stunt woman.
Rahul Mandal (2018)
Scientist Mandal swapped research labs for the kitchen and let his talent for baking shine through to win series nine.
He has since returned to his job as an engineering researcher at the University of Sheffield. Not completely turning his back on the baking world, Mandal also wrote a food column for The Times and occasionally appears on ITV’s This Morning as a guest baker.
David Atherton (2019)
After wowing the judges with his calm and collected attitude and impressive technical bakes, health adviser Atherton beat fellow finalists Steph Blackwell and Alice Fevronia to be crowned the 2019 winner.
He went on to launch a cookbook for children titled My First Cookbook, complete with sweet illustrations by his friend Rachel Stubbs.
Peter Sawkins (2020)
Student Peter Sawkins became the show’s youngest winner at 20 in 2020.
After his win, he completed his accounting and finance degree at the University of Edinburgh and released a book titled Peter Bakes.
He recently said on Instagram that he had a big announcement coming soon.
Giuseppe Dell’Anno (2021)
The Italian pastry extraordinaire Giuseppe Dell’Anno wowed judges of the 12th series, earning two star baker awards.
Since winning the show, Dell’Anno started a new job — but it wasn’t baking-related. According to his LinkedIn profile, he was employed as Senior Manager of R&D at Sealed Air Corporation in Milan, Italy, but left the role in January 2022. It seems he’s now pursuing baking full-time, as his debut book Giuseppe’s Italian Bakes was published in October 2022.
Dr Syabira Yusoff (2022)
The London cardiovascular research associate of King's College has reinvented British classic bakes with Malaysian flavours.
She won the star baker award three times in a row to take the GBBO crown in 2022. Since then, she has launched baking collections and hosted Malaysian masterclasses in cooking.
She is also a popular figure on social media, with 90,000 followers on Instagram.
