What Is Udon Stir-Fry?
It typically combines udon noodles with meat and vegetables in a simple yet flavorful sweet and savory soy-based sauce. This time around, I’m making meat-free tofu and vegetable yaki udon for a simple, satisfying vegan meal.

Udon Noodle Stir-fry Variations
- Spice: I like adding red pepper flakes. Sriracha or chili paste would work, too. Optionally, garnish the veggie yaki udon with finely sliced chili.
- Other vegetables: Bulk up this vegan udon noodle stir fry and empty the fridge to use broccoli, cauliflower, zucchini, bamboo shoots, cabbage, sugar snap peas, baby corn, mushrooms, etc.
- Mirin: A tbsp of this Japanese sweet rice wine creates a more full-bodied sauce.
- Acidity: Brighten and add tangy depth with a splash of lemon/lime juice, rice wine vinegar, or apple cider vinegar to the vegan yaki udon sauce.
- Vegan oyster sauce: Add a splash for savory, umami-rich depth.
How to Make Vegetable Udon Noodles
Step 1: First, peel and mince the garlic and ginger, then rinse, dry, and finely slice the carrot, chop the onion and bell peppers into 1-inch wedges, and dice the tofu into ½-1 inch pieces. Then, in a medium bowl, combine the vegetable broth, soy sauce, sweetener, and optional sesame oil, and red pepper flakes. Mix well, whisk in the cornstarch, and set aside.
Step 2: Heat 3 tablespoons of oil in a large wok or skillet over medium-high heat. Once hot, stir-fry the tofu until golden-brown all over, and set aside.
(Tip: Make a slurry with a little broth and the cornstarch first to avoid lumps.)
Step 3: Next, stir-fry the onion and bell pepper for a minute. Add the garlic and ginger for another minute. Add the carrots, reduce the heat to medium-low, and stir-fry for 5 minutes, or until the vegetables are tender-crisp. Then, set aside.
Step 4: Heat another tablespoon of oil over medium-high heat and add the bok choy, cooking until lightly charred on both sides. Whisk the sauce once more, then add it to the pan, lowering the heat to medium-low. Bring to a boil, whisking constantly until thickened, then remove from the heat and add the tofu and veggies, stirring well.
Step 5: Meanwhile, boil the noodles according to their package instructions, then immediately transfer to the wok/skillet. Add the green onion (if using), mix well, and leave to ‘soak’ for a minute.
Step 6: Finally, taste and adjust if necessary, then serve the veg yaki udon optionally garnished with green onion and (raw or toasted) sesame seeds. Enjoy!
Vegetable tofu udon noodle stir-fry is already a satisfying, well-balanced meal, but feel free to enjoy it alongside vegetable crispy tofu wontons/spring rolls, spicy cucumber salad, garlic soy bok choy, etc.
FAQs
Cut down on prep by preparing the chopped veggies/aromatics and preparing the sauce 2-3 days in advance. Alternatively, cook all the ingredients about 70-75%, to finish off the cooking when reheating it without sacrificing texture.
Simply, udon noodles and yakisoba noodles and two different types of wheat noodles. The former is much thicker.
Pro Recipe Tips
- Chop the veggies evenly: That way, they’ll stir-fry evenly.
- Adjust veg texture: Enjoy tender-crisp or cook for longer, until tender.
- Time-saving hack: This yaki udon recipe can be on your table in no time using a bag of pre-prepared stir-fry vegetables and pre-cooked noodles.
- More caramelized noodles: Add them to the pan while it’s still on the heat and leave to cook, undisturbed, for 30-60 seconds, to form char.

Storage Instructions
Store the cooled veggie yaki udon leftovers in an airtight container in the refrigerator for 3-4 days.
You can also freeze the leftovers for 1-2 months, though the veggies and noodles will become softer after thawing (in the refrigerator overnight).
Reheat stir fry udon noodles in a skillet over medium heat or in a microwave, adding a splash of extra water, broth, or soy if preferred if they’re a little dry.
