Ingredients You’ll Need

• 360 g (¾ lb) thin-cut sirloin steaks, sliced into thin strips
• 1 small egg
• 4 tbsp cornflour (cornstarch)
• ¼ tsp salt
• ¼ tsp black pepper
• ⅛ tsp white pepper
• 4½ tbsp sunflower oil (divided)
• 1 medium onion, thinly sliced
• 1 red chilli, finely sliced (remove seeds if you prefer mild heat)
• 1 tsp minced ginger
• 3 garlic cloves, minced
• 2 tbsp rice vinegar
• 3 tbsp dark soy sauce
• 2 tbsp tomato puree (paste for US)
• 6 tbsp caster sugar (superfine sugar)
• 2 tbsp ketchup
• 2 tbsp sweet chilli sauce (Thai-style works well)

How to Make Crispy Chilli Beef

Step 1: Prepare the Beef

Place the steak strips in a bowl, add the egg, and mix to coat thoroughly. Add cornflour, salt, black pepper, and white pepper, tossing well until every strip is evenly coated. The mixture will feel sticky — that’s what gives you the crisp coating later.

Step 2: Fry the Beef

Heat 3 tablespoons of oil in a large wok or frying pan over high heat. When hot, fry the beef in two batches. Add each strip separately to avoid clumping. Cook for about 5–6 minutes, turning occasionally, until deep golden and crisp. Remove to a bowl lined with kitchen paper and repeat with the second batch. Discard excess oil but leave about ½ tablespoon in the pan.

Step 3: Make the Sauce

Turn the heat down to medium and sauté the onion for 2 minutes until softened. Add the red chilli, minced garlic, and ginger, cooking for 30 seconds until fragrant. Pour in the rice vinegar, soy sauce, tomato puree, sugar, ketchup, and sweet chilli sauce. Let the sauce bubble for a minute or two until slightly thickened.

Step 4: Combine and Serve

Return the crispy beef to the pan, tossing it quickly in the sauce until fully coated. Heat for another minute so everything is hot and glossy. Serve immediately with boiled rice, noodles, or egg-fried rice. Garnish with sliced green onions or sesame seeds for extra flair.

Pro Tips for Success

• Partially freeze the steak for 30 minutes before slicing; this makes it easier to cut thinly.
• Always slice against the grain for the most tender results.
• Shallow frying works perfectly — no need for a deep fryer.
• For extra sauce, double the sauce ingredients. If it feels too rich, replace half the dark soy with light soy sauce.

Ingredient Swaps

You can swap sirloin for ribeye, rump, or flank steak (just slice extra thin). This recipe also works beautifully with leftover cooked meats — try shredded chicken, duck, or roast beef. Just coat and fry as you would with raw steak to achieve the same crispy finish.

Make It Gluten-Free

Replace soy sauce with tamari and double-check that your tomato puree, ketchup, sweet chilli sauce, and rice vinegar are gluten-free. The flavor stays incredible while keeping the dish suitable for gluten-sensitive eaters.

Storage and Freezing

This dish tastes best freshly made. Once cooled, the coating softens if refrigerated or frozen. However, if you must, freeze cooled portions in airtight containers for up to one month. Reheat in a hot wok or microwave until piping hot, adding a splash of water if needed.

FAQs

What’s the best beef cut for Crispy Chilli Beef?

Sirloin is ideal for its tenderness and flavor, but flank or rump can work if sliced thinly against the grain.

Can I make it ahead of time?

It’s best served immediately for crispness. However, you can prep the sauce and beef separately in advance and combine just before serving.

How do I make it less spicy?

Remove chilli seeds or reduce the number of chillies. You can also add an extra tablespoon of ketchup or sugar to balance the heat.

Can I bake it instead of frying?

Yes, but it won’t be as crispy. Bake the coated beef on a lightly oiled tray at 400°F (200°C) for 15–20 minutes, flipping halfway through.
