Equipment Needed
Step-by-Step Instructions
Follow these straightforward steps to bring together a vibrant and flavorful vegetable udon stir-fry.
Pro Tip
Make sure your pan is hot before adding the noodles and vegetables to achieve a slight char and prevent sogginess, which brings out the best texture and flavor.
Success Tips
- Use fresh or refrigerated udon noodles for best texture; dried noodles require careful cooking and rinsing.
- Cut vegetables uniformly to ensure even cooking and a balanced bite.
- Don’t overcrowd the pan; stir-fry in batches if needed to maintain high heat and crisp veggies.
- Adjust sauce ingredients to taste, adding more sweetness or spice as preferred.
- Toast sesame seeds in a dry pan before garnishing to enhance their nutty flavor.

Ingredient Swaps
If you need alternatives, these ingredient swaps work well without compromising flavor or texture.
Best Substitutions
- Replace udon noodles with soba or rice noodles for a different texture.
- Use tamari or coconut aminos instead of soy sauce for gluten-free options.
- Swap mirin with a splash of apple cider vinegar or lemon juice plus a pinch of sugar.
- Try kale or spinach instead of broccoli for a leafy green variation.
- Use sunflower or avocado oil instead of vegetable oil for a different flavor profile.
