Introduction
If you’re a fan of Japanese cuisine, you’re likely familiar with udon noodles—a thick and chewy variety of wheat noodles that is a staple in many traditional dishes. And Tempura Udon is a fantastic way to experience the unique texture and flavor of udon noodles in a hot and satisfying soup.
Tempura Udon is a popular dish enjoyed throughout Japan, known for its comforting qualities and the delightful contrast of soft noodles with crispy tempura shrimp. The dish showcases the essence of umami—the fifth taste sensation—and combines it with the vibrant flavors and freshness of the toppings.
The History of Tempura Udon
While the exact origins of Tempura Udon are unclear, it can be traced back to the Edo period in Japan (1603-1868). During this time, tempura emerged as a popular cooking method, introduced by Portuguese traders. The technique involves coating ingredients with a light batter and deep-frying them until they turn golden and crispy.
Udon noodles, on the other hand, have a longer history and are believed to have been introduced to Japan from China during the Nara period (710-794). The popularity of udon grew over the centuries, and it eventually became a staple in Japanese cuisine.
The marriage of these two culinary delights—tempura and udon—resulted in the creation of Tempura Udon. It quickly gained popularity due to its delicious flavors, hearty nature, and satisfying combination of textures. Today, Tempura Udon is enjoyed by people of all ages across Japan and beyond.
The Ingredients of Tempura Udon
To prepare Tempura Udon at home, you’ll need a variety of ingredients to create the flavorsome broth, delicate tempura shrimp, and garnishes. Let’s take a closer look at the key components:
- Udon Noodles: The star of the dish, udon noodles are made from wheat flour, salt, and water. They have a thick and chewy texture that works perfectly with the soup. You can purchase pre-packaged udon noodles from your local Asian grocery store or try making them from scratch.
- Umami Broth: The soul of Tempura Udon lies in its savory and umami-rich broth. The broth is typically made with dashi—a traditional Japanese stock that combines kombu (seaweed) and katsuobushi (dried bonito flakes). Simmered with soy sauce and mirin (Japanese sweet rice wine), the resulting broth is deeply flavored and comforting.
- Tempura Shrimp: The tempura shrimp is the crowning glory of the dish. Fresh, juicy shrimp are coated in a light and airy batter before being fried to a delicate crispiness. The tempura batter is made with a mixture of flour, egg, and ice-cold water to achieve the perfect texture.
- Garnishes: Tempura Udon is often served with various garnishes to enhance the overall experience. Common garnishes include finely chopped green onions, grated daikon radish, nori (seaweed) strips, and tempura flakes.
Making Homemade Udon Noodles
While store-bought udon noodles are convenient and readily available, making your own homemade udon noodles can be a rewarding and fun experience. The process allows you to achieve a perfect texture and flavor that is incomparable to the pre-packaged versions.
To make homemade udon noodles, you’ll need the following ingredients:
- 2 cups of all-purpose flour
- 3/4 cup of water
- 1/2 teaspoon of salt
- In a large mixing bowl, combine the flour and salt. Create a well in the center.
- Gradually pour the water into the well while stirring the flour with chopsticks or a fork. Continue mixing until the dough comes together.
- Once the dough forms a rough ball, transfer it to a lightly floured surface and knead for about 5-10 minutes until it becomes smooth and elastic.
- Shape the dough into a disk and wrap it tightly with plastic wrap. Allow it to rest at room temperature for at least 30 minutes to relax the gluten.
- After resting, roll out the dough to a thickness of about 1/8 inch. Sprinkle additional flour as needed to prevent sticking.
- Fold the rolled-out dough in half and then in half again, creating a long rectangular shape. Cut the dough into thin noodles, approximately 1/4 inch wide.
- Unfold the noodles and lightly dust them with flour to prevent sticking. Repeat the process with the remaining dough.
- Bring a large pot of water to a boil and cook the udon noodles for about 8-10 minutes, or until they reach your desired level of tenderness. Stir occasionally to prevent clumping.
- Once cooked, drain the noodles and rinse them under cold water to remove excess starch. Set aside until ready to serve.
Making homemade udon noodles requires a bit of time and effort, but the end result is truly worth it. The noodles will have a springy and satisfying texture that complements the other components of the Tempura Udon dish perfectly.
Preparing the Umami Broth
The umami broth is the soul of Tempura Udon, infusing the dish with layers of savory flavors. Here’s how you can prepare the umami broth at home:
- 4 cups of dashi stock
- 2 tablespoons of soy sauce
- 2 tablespoons of mirin
- 1 tablespoon of sake (optional)
- 1 teaspoon of salt (adjust to taste)
- In a large pot, bring the dashi stock to a gentle simmer over medium heat.
- Add the soy sauce, mirin, sake (if using), and salt to the pot. Stir well to combine.
- Allow the broth to simmer for about 5 minutes, allowing the flavors to meld together. Adjust the seasoning according to your taste preferences.
- Once the broth is seasoned to your liking, remove it from the heat and cover to keep it warm until ready to serve.
The umami broth forms the basis of the Tempura Udon dish, so it’s important to use high-quality ingredients to achieve the best flavor. The combination of dashi stock, soy sauce, mirin, and sake creates a harmonious balance of salty, sweet, and savory notes that will make your taste buds sing.
Creating Crispy Tempura Shrimp
One of the highlights of Tempura Udon is the crispy tempura shrimp. This delicate yet crunchy element adds an irresistible texture to the overall dish. Here’s how you can make delicious tempura shrimp at home:
- 10-12 large fresh shrimp, peeled and deveined
- 1 cup of all-purpose flour
- 1/4 cup of cornstarch
- 1 egg
- 1 cup of ice-cold water
- Vegetable oil, for frying
- Salt, for seasoning
- In a large mixing bowl, combine the flour and cornstarch. Whisk together to ensure they are evenly mixed.
- In a separate bowl, lightly beat the egg. Slowly pour in the ice-cold water while whisking continuously.
- Pour the egg and water mixture into the bowl with the flour and cornstarch. Gently whisk until the batter is just combined. Do not overmix—the batter should still have some lumps.
- Fill a deep pan or pot with vegetable oil and heat it to 350°F (180°C).
- Dip each shrimp into the tempura batter, ensuring that it is fully coated.
- Carefully place the battered shrimp into the hot oil one by one. Be cautious to avoid overcrowding the pan.
- Fry the shrimp for approximately 2-3 minutes, or until the batter turns golden brown and crispy. Flip the shrimp halfway through cooking for even browning.
- Using a slotted spoon or tongs, transfer the cooked shrimp to a paper towel-lined plate to drain excess oil. Season with a pinch of salt while still hot.
The key to achieving light and crispy tempura shrimp lies in the temperature of the oil. It’s important to maintain a consistent heat of 350°F (180°C) throughout the frying process to ensure the shrimp cook evenly and do not become greasy.

Tips and Tricks for Perfect Tempura Udon
- For a vegetarian version of Tempura Udon, you can replace the shrimp with an assortment of vegetables, such as sweet potato, zucchini, eggplant, and bell peppers. These vegetables make great alternatives and offer a delightful crunch when fried in tempura batter.
- To enhance the umami flavors of the broth, you can add other ingredients such as shiitake mushrooms, dried kelp (kombu), or dried bonito flakes (katsuobushi) during the simmering process.
- It’s important not to overcrowd the frying pan or pot when cooking the tempura shrimp. Frying them in small batches will ensure that they cook evenly and maintain their crispy texture.
- Serve Tempura Udon immediately after assembling to prevent the tempura from becoming soggy. The dish is best enjoyed when the noodles are still warm, and the tempura stays crispy.
Popular Variations of Tempura Udon
While the classic Tempura Udon recipe is widely cherished, there are several popular variations that offer unique twists on this traditional dish. Here are a few variations you may encounter:
- Kitsune Udon: This variation features sliced aburaage—an Asian-style deep-fried tofu pouch—added as a topping to the udon noodles. The name “Kitsune” translates to “fox” in Japanese, and the dish is named after the legendary animal that is said to enjoy tofu.
- Tanuki Udon: Tanuki Udon is characterized by the addition of tenkasu—a crunchy and slightly sweet tempura batter crumb topping. The dish gets its name from the Japanese word for “raccoon dog,” as the crispy tempura flakes resemble the animal’s bushy tail.
- Wakame Udon: In this variation, wakame—a type of edible seaweed—is added to the umami broth, imparting a subtle flavor and beautiful color to the dish. The wakame adds a touch of oceanic freshness to the overall experience.
- Tempura Donburi: Rather than serving the tempura shrimp atop udon noodles, this variation features the crispy tempura nestled on a bed of rice in a bowl. The rice is then drizzled with a savory sauce that complements the tempura perfectly.
These variations showcase the versatility of Tempura Udon, allowing you to explore different flavors and textures while still enjoying the comforting essence of the traditional dish.
