What is Hiyashi Chuka?

Hiyashi Chuka, also known as "hiyashi ramen," is a popular Japanese cold noodle dish perfect on a hot summer day.
It consists of cold ramen noodles topped with a colorful array of fresh vegetables, protein, and a soy sauce-based sauce. Classic hiyashi chuka contains cucumber, tomato, egg, and ham as toppings.
The name "hiyashi" translates to "cold" in Japanese, while "chuka" refers to Chinese cuisine, but the dish originated in Japan.
📋 Ingredients
Here are the ingredients (amounts are in the recipe card below).

- Ramen noodles: Japanese grocery stores often stock Hiyashi Chuka packs in the refrigerated section during the hot summer months. These packs conveniently include fresh ramen noodles, sauce, and furikake seasoning. See more below.
- Toppings: I selected egg, cucumber, tomato, atsuage, and furikake (rice seasoning) for this recipe. Atsuage (deep-fried tofu) is a great addition for vegetarians. You can easily substitute it with firm tofu.
- Sauce ingredients: It's easy to make homemade sauce with rice vinegar, soy sauce, sugar, and sesame oil. For a versatile twist, you can substitute rice vinegar with other types of vinegar or lemon juice. Similarly, you may replace sesame oil with olive oil or vegetable oil to suit your taste preferences.
Ramen Noodles

Japanese ramen noodles are crafted from wheat flour, water, salt, and kansui, an alkaline mineral water that gives them their distinct yellow color and firm texture. Some ramen noodles may also contain eggs.
I like to use fresh noodles like the above for the Hiyashi Chuka, but you can also find dried noodles. Either way, ramen noodles are quick to cook, and they are an excellent choice for a fast and delectable lunch option.
