What is Beef Udon?

Japanese beef udon is a traditional Japanese noodle soup consisting of a savory semi-sweet dashi broth, thick udon noodles, and thinly sliced beef.  It’s a Japanese comfort food and a staple in Japanese cuisine.

What ingredients do I need and how do you make beef udon soup?

  • Dashi – a soup base broth made from boiling bonito flakes.  This is the base responsible for giving Japanese cuisine its signature umami flavor.  You can make your own dashi by boiling bonito flake with kombu (dried kelp), use dashi packets in many Asian supermarkets or use hondashi powder as a quick alternative.
  • Soy Sauce – low sodium is preferred. For gluten free you can use tamari or coconut aminos.
  • Japanese Sake – sake used for Japanese cooking is usually fairly inexpensive and can be found in most Asian supermarkets.
  • Sweetener – to keep this recipe sugar-free, we use a monkfruit erythritol blend.  It is low carb, keto friendly and has 0 calories.  Feel free to use your preferred sweetener or regular cane sugar.
  • Salt – use your choice of salt including, table salt, sea salt, Himalayan salt etc.
  • Green Onion – sliced thinly and used for garnish.
  • Noodles – this recipe uses a healthier, low carb noodles option in shirataki noodles often called konjac noodles made from the konjac plant.  It is a healthy low carb alternative to traditional wheat flour noodles. Shirataki noodles have a high fiber content, are low in calories and gluten-free.  If you prefer, you can also use traditional udon noodles.
  • Beef – use thinly sliced meat found in many Asian or Japanese supermarkets.  The meat will usually be labeled for “Shabu shabu”

Make dashi broth and add in Japanese sake, soy sauce, sweetener, and salt. Boil shirataki noodles, stir fry beef then combine and top with sliced green onions.

  1. Oh my heavens! I just found your website. I watched the video for this recipe and I’m in love! I’ve been eating miracle and shiritaki noodles for years. In my house we love them. We also love all styles of Asian cuisine. This recipe is simple and beautiful. I cannot wait to give it a try. I must find sake. I may be wrong but I’ve been comparing soy sauces with coconut amines. I use both but much prefer the flavor of soy sauce. I absolutely love dark mushroom soy sauce and the carb counts and sugar seem good to me. What has been your experience and which do you prefer? Thank you.

      Hey Erin! So glad you found us and welcome to LCA!

      Depending on where you live, you usually can buy sake at your local supermarket, but if not, a specialty liquor store will carry it for sure. You also can replace sake for dry sherry wine if you absolutely can’t find it.

      As for the coconut amines, I’ve never used it so can’t comment on the difference/flavors. But IMO, soy sauce is such an important ingredient that I’m not willing to sacrifice the flavors of the dish/recipe to save some carbs. However, I understand this is subjective, so each to their own!

      Welcome again to LCA and let us know if you have any other questions!
