The eight celebrities arrive in New York City as Rachael Ray and Guy Fieri select their teams. The celebrities get right to work for their first cook-off challenge as they have 90 minutes to prepare a Medieval Feast and then perform for a stadium full of hungry spectators. Rachael and Guy are joined by special guest judge, Chef Lee Anne Wong, who will decide which dish does not make the cut.
Rachael and Guy challenge the celebrities to make Hawaiian-inspired hors d'oeuvres and a team cocktail to serve 50 guests at a luau party in only 90 minutes. The guests fill out comment cards rating each team's dishes, as special guest judge Chef Marc Murphy ultimately chooses the winning team and which celebrity will be eliminated.
The remaining celebrities on must create, shop, cook and package their own signature food product that best reflects their personality. Each team then has to promote and sell their products to the public for tokens, and the celebrity with the most tokens from each team wins a cash prize for their charity and is safe from elimination. Guest judge Madison Cowan rates the quality of each team's products to decide which celebrity will not be moving on to the next challenge.
Team Rachael and Team Guy go head-to-head over two rounds to create the ultimate game day grub with guest judges Chef Alex Guarnaschelli and Josh Elliott of Good Morning America determining their fate. The first round is a head-to-head chicken wing cook-off, with each team's MVP winning immunity and a cash prize for their charity. In round two, the celebrities must create the best elevated game day dish by coming up with a unique team plate of nachos. The teams are judged on both dishes, with one celebrity taken out of the lineup leaving the remaining celebrities one step closer to winning the grand prize.
The remaining celebrities arrive at the iconic Coney Island where they face-off in a mini challenge to create their own twist on French fries to win an advantage in the main challenge. Next, the celebrities will make their own signature hot dog to serve to a boardwalk full of hungry customers. Guest judge Chef Amanda Freitag joins the crowd to decide who is top dog and who will be sent home.
In the final episode, the remaining celebrities from Team Rachael and Team Guy have to prepare a three-course dinner with a five-minute presentation aboard a dinner cruise ship to entertain a panel of judges including Sunny Anderson, Scott Conant, Todd English and Aarón Sánchez. Everything is on the line to win $50,000 for their charity and receive bragging rights as winner of the Celebrity Cook-Off!
