Mrs. Child's second book, The French Chef Cookbook, was a collection of the recipes she had demonstrated on the show. It was soon followed in 1971 by Mastering the Art of French Cooking, Volume Two, again in collaboration with Simone Beck, but not with Louisette Bertholle, with whom they had ended their partnership. Julia's fourth book, From Julia Child's Kitchen, was illustrated with her husband's photographs. At the end of every show Mrs. Child would use her signature catchphrase "Bon Appetit!"

In the 1970s and 1980s, she was the star of numerous television programs, including Julia Child & Company and Dinner at Julia's. She starred in four more series in the 1990s that featured guest chefs: Cooking with Master Chefs, In Julia's Kitchen with Master Chefs, Baking with Julia, and Julia Child & Jacques Pepin Cooking at Home. She has collaborated with Jacques Pepin many times for television programs and cookbooks. All of Mrs. Child's books in this time grew out of the television series of the same names.

Mrs. Child was a favorite of audiences from the moment of her television debut on public television in 1963 and her personage was a familiar part of American culture. In 1966, she was featured on the cover of  Time magazine with the heading, "Our Lady of the Ladle". In a 1978 Saturday Night Live sketch, she was affectionately parodied by Dan Aykroyd, continuing with a cooking show despite profuse bleeding from a cut to the thumb. That same year, she was spoofed, as well, by a robotic four-armed chef named "Chef Gormaanda," played by Harvey Korman, in The Star Wars Holiday Special. Jean Stapleton portrayed her in a 1989 musical, Bon Appétit!, based on one of her televised cooking lessons. She also inspired a character on the Children's Television Workshop program, The Electric Company (1971-1977).

In 1981, she founded the educational American Institute of Wine and Food in California with vintner Robert Mondavi and others to "advance the understanding, appreciation and quality of wine and food", a pursuit she had already begun with her books and television appearances.

Her husband Paul, who was ten years older, died in 1994 after living in a nursing home for five years following a series of strokes in 1989.

In 2001, she moved to a retirement community in Santa Barbara, California, donating her house and office to Smith College. She gave her kitchen, which was designed by her husband with high counters to accommodate her diminished but still formidable height, and which served as the set for three of her television series, to the Smithsonian National Museum of American History, where it is now on display in Washington, D.C.

She received the French Legion of Honor in 1991 and the U.S. Presidential Medal of Freedom in 2003.

On August 13, 2004, Julia Child died peacefully in her sleep of kidney failure at her home in Santa Barbara, at the age of 91.
