Ingredients
Method
- Place the sliced beef in a bowl, sprinkle with baking soda, and toss to coat. Rest for 20 minutes, then rinse under cold water, drain well, and pat dry.
- Whisk together soy sauce, oyster sauce, rice vinegar, sugar, sesame oil, and white pepper. Spoon 1½ tablespoons over the beef and toss to coat.
- Whisk cornstarch into the remaining sauce, then stir in the water until smooth. Set aside.
- Heat oil in a skillet or wok over high heat. Add onion and garlic and stir-fry for 10–15 seconds until fragrant.
- Add the beef and stir-fry for about 2 minutes until mostly browned but still tender.
- Add carrot, bell pepper, bok choy stems, and white parts of green onions. Stir-fry for 1 minute.
- Pour in the sauce mixture and stir as it thickens. Add bok choy leaves and green onion tops, tossing for 30–60 seconds until just wilted.
- Serve immediately over steamed rice, garnished with sesame seeds if desired.
Notes
Slice beef thinly against the grain for best tenderness. Avoid overcooking once the sauce thickens. Add ginger with the garlic for extra aroma, or include broccoli or snap peas for variety.
