Classic Japanese kake udon β thick, silky wheat noodles in a clear, golden dashi broth seasoned with soy and mirin, topped with green onion and optional tempura crumbs.
Udon (γγ©γ) are Japan's thickest and most pillowy noodles β broad, round wheat noodles made from just flour, water, and salt β served in a delicate golden broth (kakejiru) made from dashi, soy sauce, and mirin. In their most essential form as kake udon (plain broth udon), they demonstrate a fundamental principle of Japanese cuisine: that the finest ingredients, handled with restraint, need nothing added. The slippery, chewy resistance of a well-made udon noodle against a perfectly balanced, clear broth is deeply, quietly satisfying. Udon has been eaten in Japan since at least the Nara period (710β794), possibly introduced from China. Sanuki (modern Kagawa Prefecture) on the island of Shikoku emerged as Japan's udon capital β its particular wheat flour, water, and tradition of making noodles by foot-kneading (ashi-fumikomi) produce what many consider the finest udon in Japan. The Sanuki style is characteristically firm with a bouncy, elastic texture quite different from the softer Tokyo udon. The broth differs dramatically by region: Kanto (Tokyo) udon broth is dark with soy sauce and bolder in flavor; Kansai (Osaka) udon broth is pale, delicate, and barely tinted, relying on high-quality dashi for depth. This recipe follows the Kansai style β the more elegant and harder-to-master approach. Toppings range from a poached egg (tsukimi udon) to kakiage tempura fritter, age (deep-fried tofu), or the beloved kitsune udon with its simmered sweetened aburaage tofu pouch.
Serves 2
Combine dashi, light soy sauce, mirin, and salt in a saucepan. Bring to a gentle simmer and taste carefully β it should be delicate and clearly savory. Kansai-style broth is intentionally mild; do not oversalt.
Light soy sauce (usukuchi) is saltier but much paler in color than regular soy sauce β it produces the characteristic golden Kansai broth. If using regular soy, halve the amount and adjust with salt.
Pour boiling water over aburaage to remove excess oil. Squeeze dry. Simmer in 1 tbsp soy sauce, 1 tbsp mirin, 1 tsp sugar, and 100ml water for 8 minutes until flavors are absorbed. Remove and set aside as a topping.
Bring a large pot of unsalted water to a vigorous boil. Cook fresh udon 1β2 minutes, frozen udon 2β3 minutes, dried udon per package. The noodles should be tender but retain a firm, slightly bouncy core. Drain and rinse briefly under hot water to remove surface starch.
Do not cook udon in the broth itself β surface starch from the noodles clouds and thickens the delicate clear broth.
Pour boiling water into the serving bowls for 30 seconds to warm them, then drain. Cold bowls rapidly cool udon broth β in Japan, udon restaurants heat bowls to near-scalding before service.
Divide hot noodles between warm bowls. Ladle boiling-hot broth over generously β the broth should come to the noodle level, not submerge them. Top with green onion, tenkasu, and aburaage if making kitsune udon. Serve with togarashi on the side. Eat immediately while everything is piping hot.
The quality of dashi is the entire dish β use real kombu and katsuobushi dashi, not just stock cubes, for kake udon where the broth is the star.
Fresh or frozen udon noodles are dramatically superior to dried for this dish. Look for Sanuki-brand frozen udon in Asian grocery stores.
Rinse cooked udon briefly with hot (not cold) water β cold water chills the noodles and makes reheating in the broth necessary, which clouds the broth.
Warm your serving bowls before service β udon broth cools dramatically fast in a cold ceramic bowl.
Kitsune udon: top with sweetened simmered aburaage (fried tofu pouch) β the most popular udon topping in western Japan.
Tsukimi udon: slide a raw egg into the boiling broth for 1 minute to form a poached egg topping β 'moon-viewing udon' named for the egg's resemblance to a full moon.
Yaki udon: stir-fry cooked udon noodles with pork, cabbage, and a Worcestershire-soy sauce β a completely different preparation eaten dry rather than in broth.
Cook and serve udon immediately β noodles sitting in broth absorb liquid and become bloated and starchy. Store cooked drained noodles and broth separately in the refrigerator up to 2 days. Reheat broth to a boil before assembling bowls.
Udon has been documented in Japan since the Nara period (710β794) and is thought to have been introduced from China, where similar thick wheat noodles (similar to modern Chinese mian) were well established. Kagawa Prefecture (formerly Sanuki) became udon's spiritual home through a combination of local soft wheat, mineral-rich water, and centuries of noodle-making tradition. Today Kagawa has more udon restaurants per capita than anywhere else in Japan and hosts an annual udon pilgrimage drawing hundreds of thousands of noodle enthusiasts.
Udon are thick white wheat noodles with a soft, chewy texture and mild flavor. Soba are thin grey-brown noodles made from buckwheat flour with an earthy, nutty flavor. They are used in similar dishes but are fundamentally different in taste, texture, and ingredient.
Yes β Hondashi (instant dashi powder by Ajinomoto) is widely used in Japanese home cooking, including by professional ramen and udon shop cooks. Dissolve 1 tsp per 500ml water. The result is not as nuanced as real dashi but is a perfectly acceptable weeknight shortcut.
Either they were overcooked or they were left sitting in the broth for too long before eating. Fresh udon needs only 1β2 minutes; dried udon should be checked 2 minutes before the package time. Serve immediately after assembly β noodles absorb broth and become gummy within 5 minutes.
