Easy Beef Udon Noodles Stir Fry
A quick and flavorful beef udon stir-fry with tender beef, chewy noodles, crisp vegetables, and a rich, savory sauce—perfect for an easy weeknight meal.
Ingredients
- 10 oz udon noodles
- 8 oz beef thinly sliced
- 150 g tofu diced into cubes
- 2 cloves garlic finely chopped
- 1 tsp fresh ginger thinly sliced
- 1 red onion sliced
- 2 bok choy halved
- 1 cup carrots julienned
- 2 tbsp soy sauce
- 1/2 tbsp dark soy sauce
- 1 tbsp oyster sauce
- 1 tsp honey
- 1 tbsp neutral oil
- 1 tsp sesame oil
Instructions
- In a small bowl, combine the dark soy sauce, oyster sauce, and honey. Stir well until the honey is fully dissolved. Set the sauce aside so it’s ready to use—this step keeps your cooking process smooth and controlled.
- Place the thinly sliced beef in a bowl and add the soy sauce. Mix well and let it marinate for about 15 minutes. This step helps season the meat and keeps it tender during cooking.
- Cut the tofu into even cubes. Slice the ginger, finely chop the garlic, and prepare the vegetables. Have everything ready before you start cooking—stir-frying moves quickly.
- Loosen the udon noodles according to the package instructions, usually by rinsing them in hot water. Drain well and set aside.
- Heat a large pan or wok over medium-high heat and add a little neutral oil. Add the tofu cubes in a single layer and let them cook undisturbed to develop a light golden crust. Turn gently and cook until lightly crisp on all sides. Remove and set aside.
- Increase the heat to high and add a bit more oil if needed. Add the marinated beef in a single layer and let it sear without moving for about 1 minute. Then stir-fry briefly until just cooked. Remove from the pan to keep it tender.
- In the same pan, add the red onion and cook for 1–2 minutes until slightly softened. Add the garlic and sliced ginger, stirring briefly until fragrant.
- Add the carrots and bok choy. Stir-fry over high heat, keeping everything moving so the vegetables stay crisp but tender.
- Return the beef and tofu to the pan. Add the udon noodles, then pour in the prepared stir-fry sauce. Toss everything quickly so the noodles are evenly coated and glossy.
- Drizzle in the sesame oil at the end and give everything a final toss. Taste and adjust if needed.
- Serve immediately while hot. The noodles should be glossy, well-coated, and full of balanced flavor.
Notes
- Marinate for tenderness: Even a short 15-minute marinade in soy sauce helps the beef stay juicy and flavorful.
- Slice the beef correctly: Always cut against the grain for a more tender bite.
- Prepare everything in advance: Stir-frying is fast—have all ingredients ready before you start cooking.
- Use high heat: This is key to achieving that classic stir-fry flavor and slight charring without steaming the ingredients.
- Don’t overcrowd the pan: Cook in batches if needed to keep everything searing properly.
- Crisp the tofu properly: Let it sit undisturbed at first so it develops a light golden crust and better texture.
- Control the vegetables: Keep them slightly crisp for contrast and freshness in the final dish.
