Udon is one of the most well-known Japanese dishes around the world, and you've likely seen or tried it at least once! These flour-based noodles have been around in Japan for centuries, and were originally consumed as a substitute during a period where rice wasn't easily obtainable. Now udon is widely adored by both adults and children alike all over Japan and abroad!
Udon can be served either hot or cold, and depending on how you order it, the way you eat it changes, too. It's often topped with green onions, shredded seaweed, and a sprinkle of Japanese chili flakes (ichimi or shichimi seasoning). Other common toppings include ginger, sesame seeds, and tenkasu (fried bits of deep-fried tempura batter), and you're free to adjust the flavors to your own preferences. Here are some popular ways in which udon is served and some tips on how to eat them!
General Udon Varieties
Kake udon: The most simple type of udon. Freshly boiled udon noodles that are placed in a bowl with hot tsuyu (soup broth) poured over it. In the Kanto region, it's only topped with green onions, but in the Kansai region, it's typically topped with a variety of different ingredients and is often called "su udon." The tsuyu is mildly seasoned and on the lighter side with the assumption that you'll drink it after you finish the noodles. It usually comes with a long wooden spoon to help you drink the soup. Since the noodles are soaked in the hot liquid, it's best to eat them quickly before they get too soft!
Tsukimi udon: Kake udon with a raw egg on top. Tsukimi roughly translates into "gazing at the moon" in Japanese. In this case, the egg whites represent the clouds in the sky and the yolk represents the moon!
Kamaage udon: Boiled noodles are added into a bowl with some of the water they were boiled in. Pour soy sauce over it or dip it in some tsuyu. The noodles aren't chilled immediately with cold water, so they're soft and not as firm and chewy. Kamaage udon in Miyazaki is slightly thinner than it is in other regions.
Kamatama udon: Kamatama udon with an egg cracked on top. It has very little liquid and it is only seasoned with tsuyu or soy sauce. The addition of the egg results in a mellow flavor.
Bukkake udon: After the noodles are boiled and strained, pour a little bit of soy sauce over it to eat. Toppings can vary according to personal preference.
Kitsune udon: Udon topped with an extremely popular topping called "aburaage," a sheet of fried tofu that is boiled in a sweet sauce. Some regions call it by different names, and in Osaka, where this variation originates from, it's simply called "kitsune."
Tanuki udon: Udon topped with tenkasu.
Curry udon: Udon in hot, curry-flavored tsuyu. In many households, it's made by thinning out leftover curry with tsuyu, then boiling it together with udon. It can also be made by dissolving curry roux in tsuyu.
Niku udon: Niku (meat) udon, as its name implies, is udon topped with a helping of stewed meat. Many places use pork that is cooked in a sweet sauce. It's often served hot, but there are also cold versions for the summer season.
Kenchin udon: A popular winter udon dish in which udon is added into a soup made with stir-fried daikon radish, carrots, burdock, taro, konjac, and tofu simmered in dashi (broth).
Chikara udon: Udon topped with roasted mochi (rice cake). The mochi mixes in with the noodles to create a deliciously sticky texture.
Tempura udon: Udon topped with tempura, another staple udon topping. The most common toppings are either shrimp tempura or kakiage (a cluster of shrimp and vegetable tempura). When topped with only kakiage, it is called "kakiage udon."
Yaki udon: Pan-fried udon that is cooked with a variety of different seasonings, such as dashi with a thick soy sauce-based sauce.
Nabeyaki udon: Udon that is stewed in a pot and topped with a variety of items, such as tempura, vegetables, and eggs. The noodles lose some of their springy texture, and the tsuyu soaks into the soft noodles.
Zaru udon: Chilled udon served on top of a zaru (bamboo tray). The boiled noodles are chilled with cold water, which you then dip in cold tsuyu. The tsuyu is often strong in flavor. When topped with shredded seaweed, it's called "zaru udon," but without the seaweed, it's called "mori udon."
Hiyakake udon: Boiled and chilled noodles with cold dashi poured over it.
Hiyashi bukkake udon: The noodles are boiled and strained, then chilled with cold water. Concentrated tsuyu is poured over the noodles to eat. Toppings can vary with items like green onions or grated daikon radish.
Salad udon: Boiled noodles that are chilled and topped with vegetables like lettuce and tomatoes. A small amount of tsuyu is poured over it. Soy sauce and mayonnaise-seasoned tuna is a popular topping.
Regional Udon Varieties
