Ingredients

Main Ingredients

  • 250 g Rump/Sirloin steak About 8.8oz
  • 3 cloves Garlic Cut thin slices or chopped
  • ½ Onion Cut think slices
  • 3-4 Spring Onion Cut 2" pieces
  • 1 Chilli pepper Cut thin slices
  • 2 tbsp Oil Vegetable or neutral flavour oil

Beef Marinade

  • 1 tbsp Soy sauce Light soy or regular soy sauce
  • ¼ tsp Baking soda
  • 2 tsp Cornstarch or potato starch
  • 1 tsp Sesame oil toasted sesame oil
  • ½ tsp Ginger grated ginger or ginger paste

Stir Fry Sauce

  • 2 tbsp Soy sauce light soy or all-purpose soy sauce
  • ⅓ cup Chicken stock or water
  • 2 tbsp Brown sugar
  • 1 tbsp Rice vinegar
  • ½ tsp Cornstarch or potato starch

Instructions

  • Cut the beef steak into thin slices. Mix well with the ingredients in the beef marinate list. Set aside and marinate for 20 mins.
  • In a small bowl combine stir fry sauce ingredients and whisk until sugar dissolved. Set it aside.
  • Cut garlic, onion, spring onions and chilli into thin slices.
  • Heat the pan into medium-high heat, drizzle 2 tablespoon of oil.
  • Add the marinated beef, flatten and spread the beef in the pan. Sear the beef for 2-3 minutes then flip and stir fry for another 1 minute. Remove from pan and set aside.
  • In the remaining pan, drizzle more oil if needed. Add the garlic and stir for a few seconds and follow with the onion.
  • Pour the sauce mix, let it boil for a few seconds, add the cooked beef in, stir well and cook for 1-2 mins until the sauce become thick.
  • Then add the spring onions and chilli slices, cook for another 1 min, combine well with the rest of the ingredients.
  • Serve with steamed rice or stir fry noodles.

Notes

  • For a spicier kick, add more fresh chillies or a dash of dried red pepper flakes.
  • Can I add more vegetables? Yes, you can add extra vegetables like bell peppers, carrots, baby corn, snow peas, or broccoli to add colour and texture.
  • If you prefer a thicker Mongolian sauce, increase the amount of cornstarch in the stir-fry sauce.
  • Chicken stock/broth - Instead of chicken broth or stock, use vegetable stock, beef stock, or water. 
  • To make it gluten-free, replace the soy sauce with a gluten-free soy sauce or tamari as an alternative.
  • Instead of regular soy sauce or light soy sauce, you can use low-sodium soy sauce to your taste. 
  • Instead of beef steak, you can also try this dish with chicken, lamb, or pork.
