In 1996, the group expanded to Sydney to launch the Hugos Restaurant Group. Evans moved to Sydney with his brother and David Corsi and they opened Hugos Bondi in 1996, followed by Hugos Lounge in 2000 and Hugos Bar Pizza in 2004 (both in Sydney's Kings Cross) and Hugos Manly in 2008. As the group's executive chef, Evans worked across all of the restaurants, and the catering business. The group closed Hugos Bondi in 2006 to pursue the pizza bar, rather than casual fine dining format for which Hugos Bondi was known. Over 1998–2011, the restaurants in the Hugos Group were awarded eight Sydney Morning Herald 'Chef's Hats', 21 'Best in Australia' awards, and three 'Best pizza in Australia' awards at the Australian Fine Food Show. In 2005, Hugos won 'Best pizza in the world' at the American Pizza Challenge in New York City.

His first television job was for the LifeStyle Channel's Home series (2001–2005) which he co-presented with Brendan Moar and Shannon Fricke. Evans filmed over 60 episodes of the show, which focused on styling, home, gardens, cooking and casual entertaining. In 2006 Evans, Moar and Fricke appeared in a travel-based spin-off series "Postcards from Home" (2006), which saw the trio travelling to countries outside Australia.

Evans had a monthly recipe column in The Australian Women's Weekly (2009–12) and has been a contributor to Selector magazine. In October 2012, Evans began a monthly recipe column for Home Beautiful. Evans has stated that the philosophy behind his books is that modern society is living by outdated nutritional precepts. Evans is also a motivational speaker, performing national tours in Australia. He first learned of the paleo-diet after reading the works of Nora Gedgaudas.
Evans has developed a pizza oven with Breville, a line of cookware and kitchen tools with Baccarat and a range of kitchen sinks with Clark Sinks. He is an Australian ambassador for Jacob's Creek Reserve Wines. From 2013 to 2015, Sumo Salad partnered with Pete Evans.
Evans' championing of alternative medicines has attracted criticism from peak medical bodies throughout Australia. In particular his advocacy for the paleo diet has brought about criticism from nutritionists. According to the Australian Associated Press, Evans has completed an online course with the Institute for Integrative Nutrition and describes himself as a health coach.
In 2015, Evans co-authored a cookbook titled Bubba Yum Yum: The Paleo Way for New Mums, Babies and Toddlers which raised controversy after being called “potentially deadly for babies” by health experts. Despite the controversy, My Kitchen Rules broadcaster the Seven Network claimed that public reactions to the event were not a concern, and supported Evans. Following the controversy, the authors made changes to the book.
Evans won the Australian Skeptics 2015 Bent Spoon Award for "his diet promotions, campaigns against fluoridation and support of anti-vaccinationists."
In 2016, Evans gave advice to an osteoporosis sufferer on Facebook to stop eating dairy products. His claims that the "calcium from dairy can remove the calcium from your bones” and that “most doctors do not know this information” were widely condemned by medical professionals.
Evans is opposed to fluoridation of drinking water, and considers ingredients in many sunscreen products to be poisonous.
High profile Australian medical experts have warned about the grave dangers of following Evans' advice, including the President of the Australian Medical Association Michael Gannon, Host of Embarrassing Bodies Down Under Dr Brad McKay, and obstetrician Dr Brad Robinson.
In November 2016, Evans' endorsement of earthing therapy in the Sydney Morning Herald attracted controversy.
