Kraft became a favorite at the Met very quickly in roles like Emilia in Verdi's "Otello", the drug-addicted Mrs. Sedley in Britten's "Peter Grimes", and Mamma Lucia in Franco Zeffirelli's production of Mascagni's "Cavalleria Rusticana". She was also an admired Mother Jeanne of the Holy Child Jesus in the critically acclaimed 1977 John Dexter staging of "Dialogues of the Carmelites". In describing the haunting finale of that production, "Opera News" stated, "No one who has seen Dexter’s staging of the finale will ever forget it: the chorus of doomed nuns, singing the “Salve Regina,” was diminished, one voice at a time, as each woman marched to the guillotine. Finally, only Sister Constance and Mother Jeanne were left. Slowly, Kraft’s Jeanne picked herself up and, supporting herself with her cane, hobbled defiantly to her death." Kraft later took over the role of Madame de Croissy in subsequent mountings of that production during the 1980s. Although Kraft's performances at the Met were largely in comprimario roles, she occasionally got starring parts, such as Herodias in Strauss's "Salome" (1973, 1977) initially with Grace Bumbry in the title role and Robert Nagy as Herod; Ulrica in Verdi's "Un ballo in maschera" (1970, 1976) initially with Elinor Ross as Amelia, Carlo Bergonzi as Riccardo, Merrill as Renato, and Roberta Peters as Oscar; Federica in Verdi's "Luisa Miller" (1971, 1978, 1979) initially with Adriana Maliponte as Luisa and Plácido Domingo as Rodolfo; Gertrud in "Hänsel und Gretel" (1971–1983) initially with Judith Forst as Hänsel and Joy Clements as Gretel; and Suzuki in "Madama Butterfly" (1973–1981) initially with Gilda Cruz-Romo as Cio-Cio-San and William Lewis as Pinkerton. Some of the many supporting roles she portrayed were Berta in "Il Barbiere di Siviglia" (with Marilyn Horne), Countess di Coigny in "Andrea Chénier", the Duchesse of Krakentorp in "La Fille du Régiment" (with Luciano Pavarotti and Joan Sutherland), Gertrude in "Roméo et Juliette", Grandmother Buryjovka in "Jenůfa" (with Astrid Varnay), Hecuba in "Les Troyens" (with Jon Vickers and Shirley Verrett), Ines in "Il Trovatore", Marcellina (with Teresa Stratas and Frederica von Stade), Marthe in "Faust" (with Franco Corelli), Ninetta in "I Vespri Siciliani" (with Cristina Deutekom), and the Madrigalist in "Manon Lescaut" (with Dorothy Kirsten and John Alexander) among others.
