Ingredients
Method
Prepare the noodles
- Place the wide rice noodles in a heatproof bowl and cover with hot (not boiling) water. Soak 20–30 minutes until pliable but still slightly firm. Drain and set aside.
Marinate the beef
- Toss the thinly sliced flank steak with soy sauce, oyster sauce, and cornstarch. Let sit for 15 minutes while you prep vegetables.
Cook the beef
- Heat 1 tablespoon oil in a large skillet or wok over high heat until shimmering. Add beef in a single layer and stir-fry until browned but not fully cooked through, about 1–2 minutes. Remove beef to a plate.
Stir-fry aromatics and vegetables
- Add remaining 1 tablespoon oil. Sauté garlic and ginger 20 seconds until fragrant. Add sliced onion and bell peppers; stir-fry 3–4 minutes until slightly softened but still crisp.
Combine noodles and beef
- Return the beef to the pan. Add drained noodles and toss gently to combine, using tongs or two spatulas. Stir-fry 1–2 minutes until noodles are heated through and evenly coated; avoid overmixing to prevent noodle breakage.
Finish and serve
- Add bean sprouts and chopped green onions; toss 1 more minute. Season with salt and pepper to taste. Serve immediately while hot.
Notes
Serve with garnishes like extra sliced scallions, sesame oil, or chili oil, and side dishes like cucumber salad or steamed bok choy. Store leftovers in an airtight container within 2 hours of cooking; use within 3–4 days.
