Ingredients & Substitutions

All the ingredients gathered for making a vegan udon noodle stir fry with vegetables. Each ingredient is labelled with text.

Complete list of ingredients with amounts and full instructions is located in the recipe card below. This section covers ingredient and substitution considerations.

  • Dark Soy Sauce: The combination of dark and regular soy sauce will give you the best flavour and colour in the final dish. If you don’t have dark soy sauce, you can use 1 tbsp soy sauce with 1/2 tsp molasses and 1/8 tsp sugar. You can also use dark soy sauce in this drunken noodle recipe.
  • Soy Sauce: You can use soy sauce or reduced-sodium soy sauce.
  • Vegetarian Oyster Sauce: There are a number of brands that make vegetarian oyster sauce. Look for Naked and Saucy, Lee Kum Kee or Wan Ja Shan brands. You can also use vegetarian oyster sauce in this drunken noodle recipe. If you’re not vegan or vegetarian, regular oyster sauce works.
  • Mirin: You can find mirin in well-stocked grocery stores or an Asian market. It’s a sweet rice wine used in Japanese cooking and adds amazing flavour to sauces, dressings and marinades. If you don’t have any on hand, try to find some to stock your pantry. You can also use mirin in this teriyaki chickpea bowl recipe.
  • Maple Syrup: You can use any variety of maple syrup (dark, amber, light) for the sweetness in the sauce. A suitable substitute is agave syrup.
  • Garlic: Fresh garlic is best here!
  • Udon Noodles: I recommend frozen udon noodles. They have a nice, chewy texture and are fairly easy to find. If you can’t find frozen udon noodles, try fresh udon or if needed, shelf-stable packaged udon noodles.
  • Carrot: For stir fries, I like to take the time to cut the carrot into matchsticks. They cook quickly and evenly this way. If you don’t have carrot on hand, totally fine. You can leave it out or try a different veggie like broccoli, snow peas, baby corn or snap peas.
  • Cabbage: Use green cabbage. No cabbage? No problem! Just leave it out or swap it for something like bok choy or broccoli.
  • Mushroom: Shiitake mushrooms are recommended but white or crimini mushrooms also work. If you don’t like mushrooms or don’t have any on hand, you can leave them out.
  • Green Onion: The amount doesn’t have to be exact but you want about half of the bunch you’d buy at the grocery store or about 6-7 green onions. Reserve some for topping!
  • Oil: You’ll need a bit of oil to stir fry the recipes though you could use water for an oil-free recipe. You can use a neutral oil like avocado or olive oil or for flavour, sesame oil is suitable.

How to Make Udon Stir Fry

Step 1: Prepare the Noodles.

If you’re using frozen or packaged pre-cooked udon noodles, soak them in hot water for about 1 minute, using a pair of chopsticks to gently separate the noodles. Once separated, drain and rinse under cold water and set aside.

Step 2: Prepare the Sauce.

Mix all the sauce ingredients together in a small dish.

Quick Tip: Make sure you measure the sauce ingredients accurately rather than eyeballing so you get the right balance of sweet and sour.

Step 3: Stir fry the Vegetables.

Heat 1 tbsp oil of choice in a large wok or frying pan. When the pan is hot add the carrot, cabbage and mushroom and stir fry for 5-6 minutes until they’re just tender.

Step 4: Add the Noodles & Sauce.

Add the green onion, noodles and sauce and cook for 1-2 minutes, tossing everything together until the noodles are coated in sauce.

Quick Tip: I like to mix it up (tongs work best!) then let it sit in an even layer for 1-2 minutes without stirring so the noodles crisp and brown on the bottom.

Cooking Tips

  • Tip #1: Tongs are super handy for tossing the noodles with the vegetables and sauce. If you don’t have any in your kitchen, you can purchase an inexpensive pair of tongs and use them time and time again for noodles, pasta and more!
  • Tip #2: Use a large pan or wok to stir fry. Stir fries work best with a large surface area, so use the largest pan you have to make this recipe.
  • Tip #3: Let the noodles sit in the pan for 1-2 minutes at the end so they get a little crispy on the bottom.
  • Tip #4: Be prepared. The recipe goes really quick once you start so make sure you have the ingredients prepared and sauce mixed before you start cooking.
  • Tip #5: After you break the noodles apart in hot water, rinse well under cold water to remove starch and prevent them from sticking together.

What udon noodles to buy?

  • Frozen Udon Noodles: These are my preferred choice for this stir fry and other udon noodle recipes. You can find them in the frozen foods section of well-stocked grocery stores or Asian grocery stores. They’re pre-cooked, so prepare them according to the pacakage or simply soak in hot water for a few minutes to defrost and separate the noodles before using in the recipe.
  • Shelf-Stable (Packaged) Udon Noodles: These are commonly found in well-stocked grocery stores. They’re pre-cooked and can be added directly to soups, stir fries and other dishes. Though cooked, I’d suggest soaking them in hot water briefly to gently separate the noodles.
  • Fresh udon noodles: If you have access to an Asian grocer, try the refrigerator section for fresh udon noodles. These are a great choice for recipes too!
  • Dry udon noodles: These can sometimes be found in the Asian noodle section of grocery stores or Asian grocers with other dry noodles like rice stick, lo mein, ramen, etc. These will need to be cooked separately before using in the recipe.

Udon noodles themselves can definitely be included as part of a healthy diet. Many people also find them easy to digest.

Udon noodles are primarily carbohydrate with some protein and little fat. They’re made simply from wheat, salt and water, though they do contain a range of essential vitamins and minerals.

If sodium is a concern, you may want to check the sodium content on the noodles you’re using as they can be high in sodium.

Can you make gluten-free udon stir fry?

Udon noodles are made from wheat so they are not gluten-free but there are companies make gluten-free dried udon rice noodles that you can use them in this recipe.

Otherwise, you could use a different type of noodle like egg noodles or rice noodles. It wouldn’t be an udon stir fry but it would still be tasty!

You will also need to substitute tamari for the dark and light soy sauce.

Storing & Reheating

Store: Store leftover yaki udon in the fridge in a sealed container for up to 4 days. I do not recommend freezing this recipe.

Reheating: To reheat leftovers, add them to a pan and stir fry over medium heat or microwave until heated through. If the noodles are stiking together after storing, you can add a 1-2 tbsp water to loosen them up.
