Gallagher was raised in Hawthorn Heights, Letterkenny, Donegal, where he was educated at Scoil Colmcille and St Eunan's College. In his autobiography "Back On The Menu: My Rollercoaster Life" he revealed how the kitchen was home to him as a child and how he disliked school because of the abuse he received at both institutions.
During his time in St. Eunan's College, he joined a punk band, "Kakistocracy". Inspired by the cooking of his mother and his grandmother, he left St Eunan's at the age of 16 and began training as a chef at Killybegs Catering College. Following his formal training and subsequent work with some of Ireland's top chefs to further hone his skills, Gallagher went on to win four gold medals at Hotel Olympia and the prestigious title of Chef Ireland.
While he was offered career launching positions in Ireland, he determined he should go to New York City to further pursue his dream of becoming a world class chef. In New York, he joined the Plaza Hotel. The Waldorf Astoria's Peacock Alley later recruited him where he spent two years as sous chef under Laurent Manrique. While living in New York he went on to work in Restaurant Daniel and Le Cirque. On Saint Patrick's Day 1996, Gallagher cooked for President Bill Clinton and his guests at the White House.
Gallagher came to fame with his restaurant Peacock Alley, first in Baggot Street, later on St Stephen's Green. For his work in the kitchen there he was awarded a Michelin star between 1998 and 2002.
He left Ireland to return to New York City, where he married an American citizen and opened a bar, Traffic, at First Avenue and 50th Street in Manhattan . He was accused in Dublin of stealing three paintings, worth €11,000 from Dublin's Fitzwilliam Hotel. The original contract was furnished stating Gallagher owned the three paintings and the jury returned a 'not guilty' verdict less than two hours after it started deliberations.In his autobiography, Gallagher describes the proceedings as "a bit of a circus" with days that were "long and painful." 
Whilst living in South Africa, Gallagher consulted for Sun International Group where he was appointed Group Executive Chef in 2004. He operated Geisha Wok and Noodle Bar in Cape Town, where he occasionally hosted live cooking classes. Geisha Wok and Noodle Bar stopped trading in August 2009 when Gallagher decided to move back to Ireland and open Salon Des Saveurs. He was declared bankrupt in South Africa in August 2009 following an application by two companies seeking payment of debts. Two properties and his home's contents were auctioned off to part-pay debts of about €200,000 to a bank and supplier.
After planning to return to Ireland during Summer 2009 to open a new Irish restaurant, Gallagher and his second wife, former Miss Port Elizabeth finalist Candice Coetzee and their two sons moved to Dublin. His latest restaurant is called "Salon Des Saveurs". His initial return as director of Boutique Restaurants Concepts Ltd. went sour as it is illegal to be a company director in Ireland while considered bankrupt, in or outside Ireland.
According to the Irish Independent, Gallagher ran three restaurants in July 2011: "Salon Des Saveurs" and "The Dining Room With Conrad Gallagher" in Dublin and "Conrad's Kitchen" in Sligo. "Salon Des Saveurs" and "Conrad's Kitchen" are run by Boutique Restaurants Concepts Ltd. and Super Potato Limited. Revenue Commissioners are trying to wind up these two companies.
Gallagher starred in the Head Chef TV shows for TV3 Ireland, where he developed a cooking contest reality show, before moving back to the United States in 2011.
In April 2013, Gallagher opened PoshBurger Bistro, a gourmet burger restaurant, in Las Vegas, Nevada. The restaurant could not get a liquor license and closed after three months.
In October 2013, Ways & Means Oysters in Orange hired Gallagher as a consulting executive chef to develop the menu for its location in Old Towne Orange. He left January 2014 to launch Vanity Catering and Events based in Costa Mesa. He serves as owner and executive chef.
