Pork Udon Noodle Soup (Butaniku Udon): Quick and Easy

Someone told me “If you haven’t tried Japanese noodles, you’re not going to Japan yet.” So, I decided to take a shot. My friend recommended both ramen and udon noodle soups. We headed to this renowned spot in Shibuya to eat udon – one of the best Asian noodle soup dishes, and it was an experience to remember.

Udon noodle soup is a whole different noodle ball game, especially for someone like me who is only used to Thai noodles. The texture of udon noodles is distinct. They are thicker and chewier than the thin and delicate Thai noodles. The broth is also different, it’s savory in a way that’s comforting and rich, creating a perfect harmony with the noodles.

So, here I was, trying to remake this noodle soup in my kitchen and hoping that it was not a mess. I made one of my favorite udon soup versions – Butaniku Udon or Pork Udon Noodle Soup.

First things first, the noodles. There are many types of udon noodles, including traditional wheat flour udon, whole wheat flour, brown rice flour, and even matcha (green tea) flavor udon. But you don’t need to worry about the noodles, ’cause you can buy it online. I cooked as instructions but reality hit hard. They stuck together like stubborn friends in a group photo. Here is my tip: adding a little vegetable oil after you drain them will help.

The heart of the matter is the broth. The original broth for udon noodle soup requires udon broth dashi, which is basically a Japanese stock. This contributes a distinct umami flavor to udon noodle soup. However, I replaced it with easier udon broth – pork broth.

The other steps were not too hard. I followed the steps and had this vision of perfectly slurpable Pork Udon Noodle Soup. My kitchen looked like a war zone but that rich, flavorful udon soup made it all worth it.

Best types of udon soup

There are several types of udon soup and I tried some of them. Here are some popular varieties that I want to try or try again:

  • Kake Udon: This is the classic and most simple udon noodle soup recipe. Kake udon features thick, chewy udon noodles served in a simple broth made from dashi, soy sauce, and mirin. It’s often garnished with green onions and a sprinkle of bonito flakes.
  • Kitsune Udon: Sweet and savory, kitsune udon includes a slice of deep-fried tofu called “aburaage” on top of the noodles. The name “kitsune” means fox in Japanese, and it’s said that foxes love fried tofu.
  • Tempura Udon: I love this combination of crispy shrimp tempura and udon noodles in a flavorful broth. The tempura can also include vegetables or a mix of veggies and shrimp. The contrast of the crunchy tempura and the chewy udon simply blows me away.

  • Butaniku Udon: As you know above, this udon soup features succulent slices of pork as the star of the show.
  • Curry Udon: The thick, rich curry broth pairs wonderfully with the chewy udon noodles. It’s often loaded with vegetables, meat, or tofu for a satisfying meal. This dish is on my wishlist.

  • Yaki Udon: While not a soup, yaki udon is worth mentioning. It involves stir-frying udon noodles with a variety of ingredients like vegetables, meat, and soy-based sauce.
  • Tsukimi Udon: “Tsukimi” means moon viewing in Japanese, and this udon is named for its raw egg resembling the moon. A raw egg is cracked into the hot broth, creating a silky texture. According to my friend, this dish is often enjoyed during the autumn season.

Each type of udon soup brings its own unique flavors and textures to the table. Whether the kake udon or the curry udon, they all dance on my taste buds.
