Enjoy the rich flavors of beef and mushroom stir-fry, a quick and easy dish featuring succulent steak and springy mushroom, all coated with an umami sauce.
Cut the beef filets into cubes, about ¾inch (2cm) in size. Then put them into a bowl.
Add light soy sauce, Shaoxing rice wine, water, cornstarch, and salt. Rub and swirl until the liquid is fully absorbed.
Pour in oil and mix to coat the beef cubes evenly. Leave to marinate while preparing other ingredients.
Mix the sauce
In a small bowl, mix light soy sauce, dark soy sauce, stock(or water), cornstarch, black pepper, sugar, and salt. Set aside.
Sear the beef
Heat a wok over high heat until lightly smoking (see note 2 if using non-stick cookware). Pour in 1 tablespoon of oil and swirl to coat a large area. Put in the beef cubes and spread them in a single layer.
When the bottom side touching the wok turns pale, flip and toss the beef to sear the other sides.
Once all the cubes have lost the pink color on the surface (still pink inside), transfer the beef out to a plate.
Stir-fry the dish
Pour the remaining 1 tablespoon of oil into the vacant wok. Add the halved garlic cloves first. Sizzle until they turn golden on the edge.
Add the mushroom and bell pepper. Toss them for about 30 seconds.
Return the seared beef to the wok and stir fry for one more minute until the meat is almost fully cooked.
Pour in the sauce mixture (stir it very well beforehand). Give everything a final toss until the sauce thickens to the desired consistency.
Notes
1. Sirloin steaks are a good substitute for filets. You may also use flank or skirt steaks, and cut them into slices or strips instead of cubes.2. If using a non-stick cookware, do not heat it empty. Add oil first then heat it before putting in the beef.
