Method
Make the sauce
- Whisk soy sauce, oyster sauce, brown sugar, sesame oil, cornstarch, and water together until smooth, then set aside.
- Set the sauce aside so it’s ready to pour as soon as the beef and vegetables are cooked.
Sear the beef
- Heat 2 tablespoons vegetable oil in a wok over high heat until smoking, then add beef in a single layer and sear for 1–2 minutes without stirring until browned.
- Toss briefly, then remove the beef from the wok and keep it aside.
Stir-fry the vegetables
- Add the remaining vegetable oil, then stir-fry broccoli, red bell pepper, snap peas, and mushrooms for 3–4 minutes until tender-crisp.
- Add garlic and fresh ginger and cook for 30 seconds, stirring until fragrant.
- Return the seared beef to the wok.
Coat and finish
- Pour the sauce over everything and toss until combined, then stir in the cornstarch slurry and cook until the sauce is thick and glossy—about 1 minute.
- Serve immediately over cooked rice with sesame seeds on top.
Notes
Pro tip: slice the steak very thin against the grain so it sears fast and stays tender; if the wok is not hot enough, the beef will steam instead of brown. Refrigerate leftovers in a sealed container for up to 3 days; reheat in a skillet until hot, adding a splash of water if the sauce thickens. Freezing: not recommended for best texture. Dietary swap: use tamari in place of soy sauce for a gluten-free option.
