Ingredients
Beef Coating
- 360 g (¾ lbs) thin-cut sirloin steaks (approx 3 thin steaks) cut into thin strips
- 1 small egg
- 4 tbsp cornflour (cornstarch)
- ¼ tsp salt
- ¼ tsp black pepper
- 1/8 tsp white pepper
- 4 ½ tbsp sunflower oil (divided)
Vegetables & Aromatics
- 1 medium onion, peeled and sliced into thin strips
- 1 red chilli, finely sliced (discard seeds if less heat desired)
- 1 tsp minced ginger
- 3 garlic cloves, peeled and minced
Sauce
- 2 tbsp rice vinegar
- 3 tbsp dark soy sauce
- 2 tbsp tomato puree (or tomato paste in the US)
- 6 tbsp caster sugar (or superfine sugar)
- 2 tbsp tomato ketchup
- 2 tbsp sweet chilli sauce (Thai-style recommended)
Instructions
- Prepare the beef coating: Place the thin strips of sirloin steak in a bowl and add the small egg. Mix thoroughly to coat each steak strip evenly with egg.
- Add cornflour and seasoning: Sprinkle in the cornflour, salt, black pepper, and white pepper. Toss everything together well so the steak strips are fully coated in a sticky mixture.
- Heat oil for frying: Heat 3 tablespoons of sunflower oil in a large frying pan or wok over high heat until it is very hot and shimmering.
- Fry the beef in batches: To avoid overcrowding, add half the beef strips to the hot oil a few at a time, spreading them out in the pan. Fry without moving too much for 5-6 minutes, stirring gently 3-4 times, until the beef is dark brown and crispy.
- Drain the cooked beef: Use a slotted spoon or tongs to remove the crispy beef and place it on a bowl lined with kitchen roll to absorb excess oil.
- Repeat frying: Add 1 more tablespoon of oil to the pan and fry the remaining beef in the same manner. Drain and set aside with the first batch.
- Cook aromatics: Add the remaining ½ tablespoon of oil to the pan and reduce heat to medium. Add the sliced onion and cook for 2 minutes until slightly softened.
- Add chilli, ginger, and garlic: Stir in the finely sliced red chilli, minced ginger, and minced garlic cloves. Cook for 30 seconds, stirring constantly to release their aromas.
- Make the sauce: Pour in the rice vinegar, dark soy sauce, tomato puree, caster sugar, tomato ketchup, and sweet chilli sauce. Increase the heat and let the sauce bubble for a couple of minutes until it thickens slightly and reduces.
- Combine beef and sauce: Return the crispy beef to the pan and stir to coat it evenly in the sauce. Heat through for 1-2 minutes until the beef is hot and glossy.
- Serve and enjoy: Serve the crispy chilli beef hot with steamed rice or noodles for a satisfying meal.
Notes
- For less heat, remove the seeds from the red chilli before slicing.
- Work in batches when frying to ensure the beef stays crispy and cooks evenly.
- Cornflour works better than plain flour for crispiness and helps create a light coating.
- You can adjust the sweetness and heat of the sauce by varying the sugar and sweet chilli sauce to taste.
- Leftover crispy chilli beef can be reheated gently on the stovetop but may lose some crispness.
