The majority of Minardos's work, however, was in television, where he made guest appearances in a wide variety of shows. Because of his dark looks and accent, he was often cast as a Mexican, a trend which can be seen throughout his career. These roles included that of a thief in the Maverick episode, "The Judas Mask"; a Doctor in The Twilight Zone episode "The Gift"; and two roles in the TV show Alias Smith and Jones, first as a bandit chief in "Journey from San Juan," and then as the Alcalde of a Mexican resort town in "Miracle at Santa Marta." These latter two appearances reunited him with Cannon for Cordoba co-star, Pete Duel, who played Hannibal Heyes, the alias Smith of the title. He was cast as an Italian, Giangiacomo, in the 1965 Perry Mason episode "The Case of the Sad Sicilian."
