Ingredients

[Servings : 2]

• Thinly sliced beef: 100–150 g
• Cabbage, chopped: 70 g
• Carrot, julienned: 70 g
• Onion, sliced: 80 g
• Garlic, minced: A little
• Cooked udon noodles: 2 packs
• Neutral oil: 1 tbsp
• Bonito flakes: 5 g, or to taste
• Salt and pepper: To taste

Sauce

• Soy sauce: 3 tbsp
• Mirin: 1 tbsp
• Sake: 1 tbsp
• Oyster sauce: 1–1½ tsp
• Sugar: 1/3 tsp

Optional

• Chopped green onions: As desired
• Extra soy sauce or bonito flakes: To taste

Instruction

1. Heat the oil in a frying pan over medium heat.
2. Add the garlic and cook until fragrant.
3. Add the beef, season lightly with salt and pepper, and stir-fry until just cooked.
4. Add the onion, carrot, and cabbage in that order. Cook until slightly softened.
5. Add the udon noodles and gently loosen them while stir-frying.
6. Pour in the sauce, add the bonito flakes, and toss well until the sauce evenly coats the noodles and vegetables.
7. Turn the heat to high for about 1 minute, allowing the excess moisture to evaporate and the sauce to lightly caramelize around the noodles.

Tips

• If using udon that needs to be boiled first, cook it slightly shorter than the package instructions so it doesn’t become too soft when stir-fried.
• Don’t overcook the vegetables—a little texture makes the Yaki Udon more satisfying.
• Leftover vegetables in your fridge work well here. Mushrooms, green onions, garlic chives, and bok choy are all great options.
• Thinly sliced pork can be used instead of beef. For a meatless version, try 2 eggs or a piece of aburaage (Japanese fried tofu).
• Bonito flakes add natural umami and extra savory depth without relying on an instant seasoning packet.
