A quick and flavorful beef stir fry with vibrant vegetables and a savory sauce.
In a mixing bowl, combine the cornflour, mirin, soy sauce, and sesame oil to create the marinade.
Mix the marinade thoroughly to ensure the cornflour dissolves completely for a smooth consistency.
Add the sliced beef to the marinade, ensuring all pieces are evenly coated. Let it rest for 15 minutes.
Marinating the beef enhances its flavor and tenderness.
Heat a wok over high heat and add a splash of oil. Sauté the onion, garlic, and ginger until fragrant.
Keep the heat high to quickly release the aromatics' flavors.
Add the marinated beef to the wok and stir fry until browned and cooked through.
Cook the beef in batches if necessary to avoid overcrowding the wok.
Add the broccoli, green beans, and bok choy to the wok. Stir fry for 3-4 minutes.
Cook the vegetables until they are tender-crisp for the best texture.
Pour in the water and stir to combine, scraping up any browned bits from the bottom of the wok.
This step helps to deglaze the pan and incorporate all the flavors into the sauce.
Serve the stir fry hot, garnished with sesame seeds or chopped green onions if desired.
Serve immediately to enjoy the dish at its freshest and most flavorful.
