Ingredients
Beef and 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)
Sauce and Vegetables
- 1 medium onion (peeled and sliced into thin strips)
- 1 red chilli (finely sliced, seeds discarded for less heat)
- 1 tsp minced ginger
- 3 garlic cloves (peeled and minced)
- 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
- Coat the Beef: Place the steak strips in a bowl and add the egg. Mix thoroughly to coat the steak evenly in the egg.
- Add Cornflour and Spices: Sprinkle in the cornflour, salt, black pepper, and white pepper. Toss the mixture thoroughly to form a sticky coating around each strip of beef.
- Heat Oil for Frying: Heat 3 tablespoons of sunflower oil in a large frying pan or wok over high heat until very hot and shimmering.
- Fry First Batch of Beef: Add half the beef strips to the pan, spreading them out in a single layer. Fry without excessive stirring for about 5-6 minutes until the beef is dark brown and crispy, stirring gently 3-4 times to encourage crisping.
- Drain First Batch: Use a slotted spoon or tongs to remove the crispy beef from the pan and place it on a bowl lined with kitchen paper to absorb excess oil.
- Fry Second Batch: Add an additional tablespoon of oil to the pan and repeat the frying process with the remaining beef strips. Drain and rest with the first batch.
- Sauté Onions: Add the remaining ½ tablespoon of oil to the pan, reduce heat to medium, and sauté the sliced onion for 2 minutes until slightly softened.
- Add Aromatics: Stir in the finely sliced chilli, minced ginger, and minced garlic, cooking and stirring for 30 seconds to release their flavors.
- Prepare Sauce: Add rice vinegar, dark soy sauce, tomato puree, caster sugar, tomato ketchup, and sweet chilli sauce to the pan. Turn the heat up and let the sauce bubble for a couple of minutes until slightly reduced.
- Combine Beef and Sauce: Return all the crispy beef to the pan, stir to coat them thoroughly with the sauce, and heat through for 1-2 minutes until piping hot.
- Serve: Serve the crispy chilli beef immediately alongside steamed rice or noodles for a complete meal.
Notes
- For less heat, remove chilli seeds before slicing.
- Cooking in batches prevents overcrowding, ensuring the beef crisps properly.
- Use a high smoke point oil such as sunflower for frying to avoid burning.
- Adjust sugar and chilli sauce amounts to balance sweetness and heat to personal liking.
- Leftovers can be stored in an airtight container in the refrigerator for up to 2 days and reheated gently.
