Nagasaki Champon Napolitan

Naporitan or Napolitan is a popular Japanese Western pasta dish. Instead of using an ordinary pasta sauce, this dish mainly consists of ketchup! The sweet flavor of the ketchup, tangy taste of the Worcestershire sauce, milk, and preferably thick pasta create a harmony! This “yoshoku” (Japanese-Western) dish is a popular menu in Japanese cafes/restaurants. Instead of pasta, we used our Nagasaki Champon for the noodles! The thick straight ramen noodles and sweet flavor of the sauce surprisingly taste great altogether! Skeptical of how it tastes? Try it out!
