Apparently, it was only created there. Here is the company's version of its history:
Like most great products, Rice-A-Roni® began as a well liked family recipe…
The DeDomenico family all enjoyed an old Armenian dish consisting of rice, vermicelli pasta and chicken broth. The rice and pasta were sauteed in butter before the liquid was added, giving the dish its distinctive taste.
In 1958, Vince DeDomenico decided to take this recipe and produce it for sale in grocery stores. He placed the rice and pasta in a box, and added a dry seasoning mix in place of the liquid chicken broth. Because this product was made up of half rice and half pasta, he decided to call it RICE-A-RONI®.
Chicken RICE-A-RONI was first introduced in the northwestern states in 1958. With it came the first RICE-A-RONI commercial, featuring San Francisco's Cable Cars and the now famous jingle. Created in San Francisco, RICE-A-RONI would soon be known to all as "The San Francisco Treat®!".
I long ago swore off the stuff, since the rice no longer tasted like rice, and it had more sodium in it than a person needed in a week. But I always liked the way it looked and decided to cook my own at home. It was surprisingly delicious!
