What is Naporitan?
Naporitan is a Japanese pasta dish featuring spaghetti tossed with ketchup, sausage, bacon, sliced onions, bell peppers, and mushrooms. The noodles are cooked until soft, rather than al dente. The sauce is made mainly from tomato ketchup, giving the dish a sweet and tangy flavor. Sometimes, a dash of Tabasco sauce is added for heat. The finished plate is colorful, with the red of the ketchup and peppers, and the aroma is savory and slightly sweet.
Where does Naporitan come from?
Naporitan was created in Yokohama by Shigetada Irie, chef at the Hotel New Grand, after World War II. He developed the dish for General Douglas MacArthur, who was staying at the hotel, using ingredients that were available in postwar Japan. The name comes from Naples, Italy, but the dish itself is a Japanese invention, part of the yōshoku (Western-style) tradition. The spelling varies due to differences in how Japanese renders foreign words.
How is Naporitan made?
To make Naporitan, spaghetti is boiled until soft, not firm. Sliced sausage, bacon, onions, bell peppers, and mushrooms are sautéed in a pan. Ketchup is added to the pan to form a sauce, sometimes with a splash of Tabasco for spice. The cooked spaghetti is tossed in the sauce until coated and heated through. The dish is served hot, often straight from the pan.
