15 Minute Spicy Udon Stir Fry

15 Minute Spicy Udon Stir Fry

Yes! You can be enjoying this Spicy Udon Stir Fry in just 15 minutes! Proving that delicious doesn’t need to be time consuming!

I have always been a fan of udon noodles, especially the fresh ones. They’re like fat spaghetti, so they’re fun to eat and they also grab a great sauce like nothing else. I always have them in my pantry for nights when a quick and easy dinner is needed (or when the fridge needs to be cleaned out of odds and ends :) This udon noodle recipe is made in record time – just 15 minutes from start to finish.

This stir fry is a great base recipe, featuring just a basic collection of ingredients. Feel free to add in a protein like chicken, shrimp or pork, if you’d like a meatier meal. Extra vegetables, such as mushrooms, bell peppers, bean sprouts, shredded cabbage or just about anything else you have around would also be a great addition.

How to Cook Udon Noodles

Soft, vacuum-packed udon noodles do not require any pre-cooking. You can simply add to your dish and heat through. You can pre-soak in a large bowl of warm water to loosen and separate the noodles before adding to your dish, if you like.

Frozen Udon Noodles should be cooked in a large pot of boiling water for about 1 minute.

Semi-dried udon noodles should be cooked in a large pot of boiling water for about 8 minutes.

Dried udon noodles need to cook in a large pot of boiling water for about 10 minutes.

Test for doneness by removing noodle from pot, running it under cold water, then biting. Udon shouldn’t be hard in the middle.

*I much prefer Soft or Frozen Udon noodles. They are easier to use and they have that chewy texture I love!

Cook’s Notes for 15-Minute Spicy Udon Stir Fry

For the sauce, the Sambal Oelek is responsible for the spicy part of this stir-fry. If you’re not familiar with it, look for it in the Asian sauce section of your grocery. It’s fairly easy to find these days. Any spicy Asian-style sauce (Asian Chili Garlic Sauce/Sriracha etc.) will work though. If you’re not wanting it too spicy, start with 1 tsp. of the Sambal Oelek and work your way up, as needed. Sambal Oelek packs a punch, so a little goes a long way.

This recipe uses fresh (soft) udon noodles, that usually come packaged in individual, vacuum-packed packets. My brand (President’s Choice) is sold with 4 individual packets that are 200g (7 oz.) each. I love them because they don’t need pre-cooking. That said, I do like to soak them in hot water a bit ahead, so I can separate them before adding them to the wok. It’s not necessary, but it does make it easier to stir fry them without breaking them. Alternately, you can add soft udon noodles directly from the package to the wok.

If you want to try this using dried udon, you’ll obviously need to cook them before adding to the wok. You may also need to increase the sauce ingredients, as I suspect dried noodles might soak up a bit more that the fresh ones. Truth be told though, I am not a fan of dried udon and don’t think they’re nearly worth the extra work of having to boil them.

For the carrots, I suggest spiralized carrots, as they cook up quickly in a stir fry. You can either use store-bought spiralized carrots or spiralized your own at home (I have one of these simple handheld spiralizers that works great!). Simply chop the spiralized carrots into bite-sized pieces to prepare. Store-bought, spiralized carrots tend to be a little thicker, so allow a bit more cooking time at the start to get them tender, before adding the onions. Alternately, I would suggest just grating some carrot on a box grater to add to the stir fry.

I’ve used carrots and spinach here, but you can use whatever vegetables you like. Just consider cooking time in the wok and add the longer-to-cook ones first (and cut in small pieces). Greens would usually go in last and cooked until wilted.

Add a protein! Chicken is a great addition to this dish, either cooked chicken or cook a bit of chicken in the wok before starting the stir fry (remove to a plate, then add back in towards the end, to warm).

This recipe will serve 2 as a main dish or 4 as a side dish. To serve more, simply double the recipe!

This quick and easy recipe makes 2 main dish servings, or 4 servings as a side dish. If needing more, simply double the recipe. This is a great base recipe, that is ripe for addition add-ins. Chicken, shrimp or pork is a nice addition for a meal. Extra vegetables, such as mushrooms, bell peppers, bean sprouts, chopped cabbage or just about anything else you might have around would also be great.


Stir Fry:

  • 1 Tbsp vegetable oil or other neutral cooking oil
  • 1/2 medium onion sliced or diced
  • 1 medium carrots spiralized and chopped or grated
  • 1 cup green onion sliced diagonally (green part only)
  • 3 cups baby spinach
  • 14 oz soft vacuum-packed udon noodles 400g


  • 1-2 tsp Sambal Oelek (or Asian Chili Garlic Sauce/Sriracha)
  • 1/4 cup soy sauce
  • 2 tsp rice wine vinegar
  • 1 tsp sesame oil
  • 2 Tbsp brown sugar
  • 2 cloves garlic minced
  • 1 Tbsp fresh ginger minced

For garnish:

  • Sesame seeds
  • Additional sliced green onion
  • 1/4 cup chopped parsley or cilantro


  1. Prepare your vegetables and set aside. Mix up the sauce by combining all the ingredients in a small bowl. Set aside. If you like, you can fill a large bowl with hot tap water and add udon noodles to the bowl to soak, so they can be separated before adding to the wok This isn't necessary though, as you can add fresh udon noodles directly from the package to the wok. I just find it easier to stir fry them having them separate before the go in to the wok.

  2. In a large frying pan or wok, heat oil over medium-high heat until very hot. Add carrots and cook, stirring for a minute or so. Add onions and cook, stirring, until onions are soft and carrots are tender. Add green onion and cook, stirring, for 30 seconds or so.

  3. If soaking udon noodles, gently stir to loosen udon noodles and separate, then drain. Add drained noodles (or unsoaked noodles)to the wok and cook, stirring, for 30 seconds or so. (Stir fry a little longer is soaked, to cook off any extra water before adding the sauce). Add sauce and cook for another 30 second, stirring to combine well. Scatter baby spinach over top and cook, stirring constantly, until spinach is wilted.

  4. Remove stir fry to a bowl or plate and garnish with sesame seeds, additional sliced green onion and parsley/cilantro.

  • This looks delish! Do you use dark, light or sweet soy sauce? I only have sweet and light soy sauces on hand but would love to make this x

  • Udon noodles? Are they just back east? I don’t ever recall seeing them in the store. Here I see steam fried noodles or fried noodles. Or suggestions to use vermicelli or spaghetti noodles instead. Where would I look for them?
    Would love to try some of these recipes, but don’t know what I could substitute for these noodles. Thanks for your help, and the recipes.

    • Hi Pat, I’m in Canada and they are quite easily available here. They are soft and packaged in individual serving vacuum packed packages. Because they are soft, they can go straight into the stir fry, without pre-boiling. That said, you can substitute any dried noodle by boiling it first before adding to the stir fry. It obviously will make this dish more work. FYI, I found the type of noodles I’m talking about on amazon.com, if you might like to order some. I love them and they are a great item to have in your pantry for dishes like this! Here’s the link on amazon – http://www.amazon.com/Amoy-Straight-Udon-Thick-Noodles/dp/B00Y2I35QC/ref=sr_1_9?ie=UTF8&qid=1452460989&sr=8-9&keywords=amoy+straight+to+wok

      • Thank You , I will look them up on Amazon. I too live in Canada, in Kitchener, British Columbia. I have to travel to Creston , B.C. to the nearest stores. We have an Extra Foods and an Overwaitea. I will check to see if I can find them at either of these stores ( I’ll ask the people who stock the shelves, they seem to know more than anyone where to find things.).
        Thanks again for the quick reply.

        • If you have access to any of the Loblaws affiliated stores, look for the President’s Choice brand soft udon noodles. They are in with the Asian noodles/sauces at my store.

  • About to make this for dinner. LOVE your website! I’m going to make two of your other recipes later on this week. From another Muskoka resident :)

    • Hi Zoe! Wasn’t it just a perfect Thanksgiving weekend in Muskoka?!! Hope you enjoyed the udon. It’s one of my favourite quick dinners :)

      • It was a great sunny and warm weekend! the udon was so so good, will definitely make it again! I made the chicken, artichoke and sundried toms tonight! another winner :)

  • Hello,
    I love this recipe! However I never know which type of onion to use . Can you tell me if I am supposed to use red, white, or yellow onions?
    Thank you!

    • Hi Michelle, When it comes to recipes, I always assume “onion” means yellow cooking onions and I use that assumption when I write recipes, as well. These are really the standard for onions. I rarely use white onions, unless specified in a recipe. Red onion is most often used in recipes where the onion is uncooked, as it is milder and adds great colour to salads etc. If you only want to buy one type of onion, keep an ample supply of yellow cooking onions of various sizes around. You can’t go wrong with that :)

  • Nothing is more comforting than a big bowl of noodles. This looks so good, Jennifer! I’ve got several feet of snow to shovel out. Wish someone was making me this so I could come in the house to a warm bowl of stir fry!

    • Thanks Liz. I’ve been following your storm on the news. Sounds like you need a spicy bowl to warm you up! Stay warm :)

  • Yes! I need to cook with udon more often. I love any noodle, but they have that great udon chew! This sounds so yummy (and meatless)! I need more quick meals in my arsenal like this…. 15 minutes is about all I’ve got so a lot of dinners lately have just been protein shakes! AHK!

I love hearing from you, so if you have a question or something isn't quite clear, I'm happy to help. If you made this recipe, I'd love to know how you liked it ~ Jennifer
