Ingredients

Scale
  • 8 oz beef sirloin or flank steak, thinly sliced against the grain
  • 1 tbsp soy sauce
  • 1/2 tsp cornstarch
  • 1/2 tsp freshly cracked black pepper
  • 1 tsp sesame oil
  • 2 tbsp soy sauce (low-sodium if preferred)
  • 1 tbsp oyster sauce
  • 1 tbsp dark soy sauce (optional)
  • 1 tbsp mirin or rice wine (or pinch of sugar as substitute)
  • 2 tsp freshly cracked black pepper
  • 1 tsp sugar
  • 14 oz fresh or frozen udon noodles (or shelf-stable, soaked to loosen)
  • 1 tbsp neutral oil (canola or vegetable)
  • 3 cloves garlic, minced
  • 1 medium onion, thinly sliced
  • 1 bell pepper, julienned
  • 2 scallions, sliced (reserve some green tops for garnish)
  • Optional: 1 cup snap peas, baby bok choy, or mushrooms
  • Extra scallions, finely chopped (for garnish)
  • Toasted sesame seeds (for garnish)
  • More freshly cracked black pepper (for garnish)

Instructions

  1. In a medium bowl, combine sliced beef, 1 tbsp soy sauce, 1/2 tsp cornstarch, 1/2 tsp black pepper, and 1 tsp sesame oil. Toss well and marinate for at least 10 minutes (up to 30 minutes in the fridge).
  2. In a small bowl, whisk together 2 tbsp soy sauce, 1 tbsp oyster sauce, 1 tbsp dark soy sauce, 1 tbsp mirin, 2 tsp black pepper, and 1 tsp sugar. Set aside.
  3. Prepare udon noodles according to package instructions (boil or soak as needed), drain well, and gently separate.
  4. Heat 1 tbsp oil in a large wok or skillet over high heat. Add marinated beef in a single layer and sear for 1-2 minutes, flipping once, until just browned but not fully cooked. Transfer beef to a plate.
  5. In the same pan, add a bit more oil if needed. Add minced garlic and sliced onion, sauté for 1 minute until fragrant. Add bell pepper and any optional veggies, stir-fry for 2-3 minutes until crisp-tender.
  6. Add drained udon noodles to the pan. Pour in the sauce and toss everything together. Return beef (with juices) to the pan. Stir-fry for 2-3 minutes until noodles are hot and glossy with sauce. Add a splash of water if noodles clump.
  7. Add most of the sliced scallions (reserve some for garnish). Taste and adjust seasoning with more black pepper or soy sauce if desired.
  8. Divide noodles between bowls. Top with extra scallions, toasted sesame seeds, and more black pepper. Serve immediately.

Notes

For best results, use freshly cracked black pepper and slice beef thinly against the grain. Prep all ingredients before starting, as stir-frying moves quickly. Adjust veggies and protein to your preference—chicken, shrimp, or tofu work well. For gluten-free, use rice noodles and tamari. Leftovers keep for up to 2 days in the fridge; reheat gently with a splash of water.
