Yakisoba (Japanese: 焼きそば [jakiꜜsoba]), "fried noodle", is a Japanese noodle stir-fried dish. Usually, soba noodles are made from buckwheat flour, but soba in yakisoba are Chinese-style noodles (chuuka soba) made from wheat flour, typically flavored with a condiment similar to Worcestershire sauce. The dish first appeared in food stalls in Japan around the 1930s.
Yakisoba is prepared by frying ramen-style wheat noodles with bite-sized pork and finely chopped vegetables like cabbage, onions, bean sprouts, and carrots. It is then flavored with Japanese-style Worcestershire sauce, salt, and pepper. It can be served with a variety of garnishes, such as aonori (seaweed powder), beni shōga (shredded pickled ginger), katsuobushi (bonito fish flakes), or Japanese-style mayonnaise.
Yakisoba is most familiarly served on a plate either as a main dish or a side dish.
A more novel way of serving yakisoba in Japan is to pile the noodles into a bun sliced down the middle in the style of a hot dog, and garnish the top with mayonnaise and shreds of red pickled ginger. Called yakisoba-pan (pan meaning "bread"), it is commonly available at konbini (convenience stores) and school canteens.
Sometimes, udon is used as a replacement for the ramen-style noodles and called yakiudon. This variation originates in Kitakyushu or Kokura, in Fukuoka Prefecture.
In Okinawa, yakisoba is popular with locals as well as US service members stationed on the island. After the 1945 hostilities with Japan ended on Okinawa, the US military command supplied American food products to the displaced and malnourished islanders. Yakisoba was prepared with alternative packaged ingredients such as spaghetti, spam, ketchup, any available vegetable (usually canned), and mayonnaise. Mess halls and other on-base eateries often serve yakisoba.
Along with typical Okinawan meats such as pork or chicken, fried spam, chopped hot dogs, and sliced ham are still popular postwar additions to yakisoba eaten by islanders today, along with common local vegetables such as cabbage and carrots.Okinawa-style yakisoba is generally made with Okinawa soba, a wheat noodle much thicker than what is commonly used for yakisoba in the rest of Japan, and flavored with pre-packaged yakisoba sauce.
Sōsu-yakisoba was thought to be invented in the post-WWII era, but recent studies indicate it appeared around the end of Taishō or early Shōwa (1926–1989) periods.
