Step‑by‑Step Cooking Directions

1. Marinate the Beef:

   • In a large bowl, toss the sliced beef with 1 tbsp soy sauce and 1 tbsp cornstarch until each strip is lightly coated. Let rest for 5 minutes while you prepare other components.

2. Cook the Noodles:

   • Bring a pot of salted water to a boil. Cook noodles according to package instructions until just al dente. Drain, rinse under cold water to stop cooking, and toss with a drizzle of oil to prevent sticking. Set aside.

3. Prepare the Sauce:

   • In a small bowl, whisk together the remaining 2 tbsp soy sauce, 1 tbsp cornstarch, brown sugar, oyster sauce, hoisin sauce, rice vinegar, and sesame oil until smooth. Set aside.

4. Sear the Beef:

   • Heat 2 tbsp vegetable oil in a large wok or heavy‑bottomed skillet over high heat until shimmering.

   • Working in a single layer, sear half the beef strips for 1 minute per side, until just browned. Transfer to a plate. Repeat with the remaining beef, adding oil if needed.

5. Stir‑Fry Aromatics & Vegetables:

   • Reduce heat to medium‑high and add 1 tbsp oil to the wok.

   • Add minced garlic, minced ginger, and the white parts of the scallions. Stir‑fry 30 seconds until fragrant.

   • Add julienned carrots and bell pepper. Stir‑fry for 2 minutes, until vegetables just begin to soften.

   • If using bok choy or snow peas, add now and stir‑fry another 1 minute.

6. Combine Beef, Sauce & Noodles:

   • Return seared beef to the wok along with any accumulated juices.

   • Give the prepared sauce a quick stir (cornstarch may settle) and pour into the wok. Stir continuously for 1–2 minutes, until the sauce thickens and coats the beef and vegetables.

   • Add the cooked noodles and the green parts of the scallions. Toss vigorously for 1 minute to incorporate noodles, ensuring every strand is glossy with sauce.

7. Garnish & Serve:

   • Transfer to a warmed serving platter or individual bowls.

   • Sprinkle with sesame seeds and chopped cilantro or extra scallion greens, if desired. Serve immediately.

Combining these caramelized beef strips with noodles creates a satisfying one‑pan meal. Today, this dish is a staple on Chinese‑American menus and has inspired countless home‑cook adaptations worldwide.
