Why This Recipe Works

The key to making great Japanese Udon Noodles lies in the balance of flavors and textures. We'll start by creating a rich dashi broth, made with kombu seaweed and katsuobushi (dried bonito flakes), which provides a deep, savory foundation for our noodles.

Next, we'll cook our Udon Noodles to perfection, using a combination of boiling and soaking to achieve the ideal texture. This step is crucial, as overcooking can lead to mushy noodles, while undercooking can result in a unpleasant chewiness.

Finally, we'll assemble our Udon Noodles, adding a variety of toppings and seasonings to enhance the flavor and visual appeal. From sliced scallions and grated ginger to savory tempura bits and boiled eggs, the possibilities are endless, and I'll provide you with plenty of ideas to get you started.

How to Make Japanese Udon Noodles

1
In a large heavy pot or Dutch oven, combine the kombu seaweed and water, and bring to a boil over high heat. Reduce the heat to low and simmer for 10-15 minutes, or until the kombu is tender and the liquid has reduced slightly.
2
Remove the kombu from the pot and add the katsuobushi, soy sauce, sake, mirin, sugar, and salt. Bring the mixture to a simmer over medium heat, and cook for 5-7 minutes, or until the flavors have melded together and the liquid has reduced slightly.
3
While the broth is cooking, prepare the Udon Noodles according to the package instructions. Typically, this involves boiling the noodles in water for 8-10 minutes, or until they are tender but still slightly firm in the center.
4
Once the noodles are cooked, drain them in a colander or strainer and rinse them with cold water to stop the cooking process.
5
To assemble the Udon Noodles, place a portion of the noodles in a serving bowl and ladle the hot broth over the top. Add your desired toppings, such as tempura bits, sliced scallions, and grated ginger.
6
Serve the Udon Noodles immediately, garnished with additional scallions and ginger if desired.
7
To make the tempura bits, heat about 2-3 inches (5-7.5 cm) of vegetable oil in a deep frying pan over medium-high heat until it reaches 350°F (175°C). Carefully add the tempura bits to the hot oil and fry until they are golden brown and crispy, about 2-3 minutes. Drain the tempura bits on paper towels and season with salt to taste.
8
To make the grated ginger, peel the ginger using a spoon or vegetable peeler, and then grate it using a fine grater or microplane. Squeeze the grated ginger in a cheesecloth or fine-mesh strainer to remove excess moisture.
9
To slice the scallions, trim the ends and cut the scallions into thin slices using a sharp chef's knife. Rinse the sliced scallions in cold water to remove excess moisture, and then pat them dry with paper towels.
10
To cook the Udon Noodles, bring a large pot of water to a boil and add the noodles. Cook the noodles for 8-10 minutes, or until they are tender but still slightly firm in the center. Check the noodles for doneness by biting into one; it should be slightly firm in the center but yielding to the bite.
11
To check the temperature of the broth, use an instant-read thermometer to ensure it has reached a simmer, which is typically between 180°F (82°C) and 190°F (88°C).
12
To rest the Udon Noodles, place them in a serving bowl and let them sit for 2-3 minutes before serving. This allows the noodles to absorb the flavors of the broth and the toppings.
13
To finish the dish, garnish the Udon Noodles with additional scallions, ginger, and tempura bits, and serve immediately.

Make-Ahead, Storage, Freezing and Reheating

Leftover Udon Noodles can be refrigerated for up to 3 days or frozen for up to 2 months. To refrigerate, place the noodles in an airtight container and store them in the refrigerator at a temperature of 40°F (4°C) or below. To freeze, place the noodles in an airtight container or freezer bag and store them in the freezer at a temperature of 0°F (-18°C) or below.

To reheat the noodles, simply place them in a pot of boiling water or in the microwave with a little water. You can also add the noodles to the hot broth and simmer them for a few minutes to restore their texture and flavor.

When reheating the noodles, be sure to check the temperature of the broth to ensure it has reached a simmer, which is typically between 180°F (82°C) and 190°F (88°C). You can use an instant-read thermometer to check the temperature.

It's also important to note that the noodles will absorb more liquid as they sit, so you may need to adjust the amount of broth or water when reheating. Additionally, the noodles may become slightly sticky or mushy after refrigeration or freezing, but this can be minimized by rinsing them with cold water before reheating.
