Tanuki Udon
Tanuki Udon, named after the Japanese raccoon dog, features tenkasu (tempura bits) as an essential topping. The name's origin has various theories, with one suggesting that the color of tenkasu resembles that of the raccoon. Many also enjoy cold Tanuki Udon for a refreshing twist.
📋 Ingredients
Here are the ingredients (amounts are in the recipe card below).

- Udon noodles: See below.
- Tenkasu (see below), wakame seaweed, and scallions (green onions) for the toppings.
- Dashi powder, salt, mirin, and soy sauce for noodle soup. Dashi, a traditional Japanese soup stock, is the key ingredient in infusing the broth with savory richness (find more in What is dashi). In this recipe, I simplify the process by using store-bought kombu dashi powder. If you like to make homemade noodle soup from scratch, try this Mentsuyu recipe!
Udon Noodles

The popular Japanese noodles, made with wheat flour and water, are a staple of Japanese cuisine. These thick and chewy noodles can be enjoyed both hot and cold.
At Japanese grocery stores or Asian markets, you can find udon noodles in different forms - dried, fresh, or frozen. In this recipe, I opt for frozen udon noodles for their quick preparation, requiring just a few minutes of boiling.
Tenkasu (Tempura Bits)

Tenkasu, or agedama, are crispy tempura flakes—small, crunchy bits made as a byproduct during tempura frying. Tenkasu is often used as a topping in Japanese dishes, adding crunchiness and flavor to soups, noodles, and other dishes.
I use store-bought tenkasu for this recipe, but making your tempura bits is easy. Prepare a tempura batter, apply a generous amount to a brush, and gently drop it into the hot oil. Fry for approximately 2 minutes or until golden brown.

Helpful tips
- Adjusting Soup Seasoning: If your udon soup is too salty, you can balance it by diluting it with water. Conversely, if it's too mild, add more salt to enhance the flavor.
- Udon noodles typically take a couple of minutes to cook frozen noodles and around 10 minutes or more for dried or fresh noodles. The cooking time can vary depending on the type and brand of udon noodles, so please follow the package directions.
- Tenkasu will become soft over time, so add it right before you eat for a crunchy texture.
