On this Food Network special series, he lost two battles with American Iron Chefs Mario Batali and Wolfgang Puck, but won a tag team battle along with partner Bobby Flay against Batali and Sakai.

When Puck was unavailable, Morimoto came on board to replace him.
His voice is usually dubbed by American voiceover personality Joe Cipriano during the judgment phase of the show; during the battle, his use of English is not dubbed, but conversations with his sous-chefs in Japanese are subtitled.
In 2007, Morimoto's third year at Iron Chef America, he published his first cookbook, Morimoto: The Art of New Japanese Cooking.

As of December 2012, Morimoto's win/loss/tie record on Iron Chef America is 25–14–1, and his total combined record for both Iron Chef series is 41–21–2.

Morimoto opened a restaurant in the Boca Raton Resort & Club in late 2008.
