What are udon noodles?

Udon noodles are delicious, chewy noodles that originated in Japan. These thick, chewy udon noodles are made from wheat flour, water and salt. Udon noodles are a staple in Japanese cuisine, as they’re made into many recipes such as beef udon soup, beef yaki udon stir-fries and more. 

There are a few varieties of udon noodles, either flat or rounded. Each type of udon noodle has a specific purpose, depending on its shape. For example, some udon noodles are better for slurping due to their shape, so they’re served in a hot broth (like dashi broth).

Where can I buy udon noodles?

Most supermarkets carry udon noodles in the Asian section, near other available noodle varieties. If your local store doesn’t carry udon noodles, you can also find them at Asian or Japanese markets. 

If all else fails, you can easily order udon noodles online and have them delivered to your door, so you can create beef udon (aka beef yaki)!

Udon Noodles
Udon noodles help make this beef udon noodles dish more filling! If you can’t find udon noodles, soba noodles will also work. Alternatively, you can use pasta, though the consistency and flavour will be slightly different.

Beef Tenderloin
I love adding beef tenderloin to this recipe as a source of protein. You can also use chicken, pork, tofu or any protein you have.

Like ginger, garlic adds a yummy aroma and helps provide the flavour base for this dish. You can always use powdered garlic, though the flavour will be stronger with the powdered form.

Pak Choi
Pak choi is also known as bok choy, boosts nutrients in this dish and its flavour is similar to cabbage, so it absorbs the other seasonings and sauces well.

How to make beef udon stir fry

  1. Start the udon beef dish by adding the beef strips into a large bowl and tossing with cornflour until well-coated (Image 1).
  2. Then, add half of the rapeseed oil into a pan and heat it on high heat. Once the oil is hot enough, transfer half the beef into the pan. Cook the beef for about two minutes on each side, ensuring you flip halfway through.

    Once the first batch of beef is ready, set it aside and continue with the second half of the beef. Set all the cooked beef aside once fully cooked and sprinkle salt over the top (Image 2).

3. Chop the pak choi, slice the red onions and wash the mange tout (Image 3).

4. Continue the chow udon recipe by adding the second half of the rapeseed oil to the pan. Next, add the mange tout and onion, sprinkling salt and chilli flakes. Saute these ingredients until they soften, for a few minutes (Image 4).

5. Then, add the thick udon noodles in a layer and top with the pak choi. Add a tablespoon or two of water, cover with a lid and decrease the heat to medium (Image 5).

6. The noodles should take about four minutes to separate (without breaking into smaller pieces). Finally, add the sauces into the pan, including the soy sauce, sweet soy sauce, rice vinegar, and an extra pinch of salt. Give the pot a good stir to ensure the flavours are incorporated well (Image 6).

7. When serving, you can add a helping of broccoli and some fresh coriander to help boost the nutrient content. If you’re meal prepping this beef udon noodle recipe, separate it into five servings. Then add broccoli and fresh coriander to each container (Image 7).

Other udon recipe ideas

Substitute the beef for tofu for a vegan/vegetarian-friendly version. You can also make a pescatarian version by using shrimp or fish.

Tips and Tricks

  • Avoid crowding the pan when frying the beef. We want each piece of beef to have enough room to fry without steaming the other pieces. This would prevent browning and reduce flavour.
  • Fry the beef on high heat for a short amount of time. This will maximise browning and prevent overcooking.
  • Don’t try to separate the udon noodles before they have been steamed within the pan. This will cause them to break apart.

What type of beef should I use for beef udon stir fry?

For beef udon stir fry, it is recommended to use thinly sliced tenderloin,flank steak, sirloin, or ribeye. The meat should be cut against the grain to ensure tenderness.

Can I substitute udon noodles with other types of noodles?

Yes, you can substitute udon noodles with other types of noodles such as soba noodles, rice noodles, or even spaghetti. However, keep in mind that the texture and taste may differ from the traditional udon noodles.

How do I cook the beef to ensure it’s tender in the stir fry?

Cook the beef quickly over high heat to avoid overcooking and making it tough. If you cook it for longer over a lower heat, you’ll dry out the beef which would make it chewy and less tender. 

Can I make the stir fry sauce ahead of time?

Yes, you can make the stir fry sauce ahead of time and store it in the refrigerator until ready to use. Just be sure to give it a good stir before adding it to the stir fry.
