Cut the beef steak into thin slices or thin strips against the grain. Place the beef slices into a bowl and add marinade ingredients. Mix it well and set them aside for 10-15 minutes. Combine the sauce ingredients in a small bowl and set it aside.
Step 2
Heat the large wok/pan over medium-high heat. Drizzle 2 tbsp of oil and sear the beef for 2-3 minutes or until the beef is charred. Then flip the beef slices and stir fry for another 1-2 minutes until no longer pink. Remove the beef from the pan and set it aside.
Step 3
Wipe clean any crumbles and burnt bits left in the remaining pan. Drizzle 1 tbsp of oil and stir-fry the garlic and onions for a few seconds until fragrant. Follow by broccoli, baby corn, carrot, and mushroom. Next, add celery and mangetout.
Step 4
Pour the sauce into the pan and bring it to a simmer. Place the cooked beef back in the pan and add the bean sprouts and make a quick toss.
Step 5
Add corn starch slurry and stir everything well until the sauce is thick and glossy. Serve immediately with plain rice or noodles. Ingredients and variations
