🥩 Ingredients

🔸 For the Crispy Beef:

300g (10 oz) sirloin or flank steak, thinly sliced into strips
1½ tbsp cornflour (cornstarch)
1 tbsp plain flour (all-purpose)
½ tsp baking powder (optional, for extra crisp)
1 tbsp soy sauce
½ tsp white pepper
1 tsp sesame oil (optional)
Spray oil (or light drizzle of vegetable oil)

🔸 For the Sticky Chilli Sauce:

1 tbsp vegetable oil
2–3 cloves garlic, minced
1-inch piece ginger, minced or grated
1 small red chilli, finely sliced (adjust to heat preference)
1 tbsp tomato ketchup
2 tbsp sweet chilli sauce
1 tbsp soy sauce
1 tbsp rice vinegar or white vinegar
1½ tbsp brown sugar (or honey)
2 tbsp water

🔸 Optional for Serving:

Spring onions (sliced)
Toasted sesame seeds
Steamed rice or noodles

🍽️ Equipment

Air fryer (any basket style or oven type)
Mixing bowls
Small saucepan for sauce

🔥 Instructions

STEP 1: Marinate the Beef

Thinly slice the beef into matchstick-sized strips.
In a bowl, toss with:
- Soy sauce
- White pepper
- Optional: Sesame oil
Let it marinate for 10–15 minutes (or up to 1 hour in fridge).

STEP 2: Coat for Crispiness

In another bowl, mix:
- Cornflour, plain flour, and baking powder
Toss the marinated beef in the dry mix until fully coated.

STEP 3: Air Fry the Beef

Preheat air fryer to 200°C (390°F) for 3–5 minutes.
Place beef strips in the air fryer basket in a single layer (work in batches if needed).
Spray or lightly drizzle with oil.
Air fry for 10–12 minutes, shaking halfway through, until:
- Deep golden brown
- Crispy on the outside, tender inside

✅ Tip: Thinner beef = faster, crispier result

STEP 4: Make the Sticky Chilli Sauce

While beef is cooking, heat 1 tbsp oil in a pan.
Add garlic, ginger, and chilli. Stir-fry for 30 seconds.
Add:
- Ketchup
- Sweet chilli sauce
- Soy sauce
- Vinegar
- Brown sugar
- Water
Simmer for 2–3 minutes until glossy and slightly thickened.

STEP 5: Combine & Serve

Once beef is done, toss it immediately in the hot sauce or drizzle sauce on top.
Sprinkle with spring onions and sesame seeds.
Serve over steamed rice or noodles.

🍚 Serving Suggestion

Best served immediately while crispy! Pairs well with:

Egg fried rice
Stir-fried vegetables
Simple cucumber salad for cooling contrast

❓ Crispy Chilli Beef Q&A

❓ Q: Can I use another cut of beef?

A: Yes! Sirloin, flank, or even rump steak works well. Slice thinly against the grain for tenderness.

❓ Q: Why isn’t my beef crispy?

A: Possible causes:

Too much moisture: Pat beef dry before coating
Not enough oil spray: A light mist helps crisp the coating
Overcrowding: Air fry in a single layer, in batches if needed
Air fryer too cold: Preheat for 3–5 minutes before adding food

❓ Q: Can I make this gluten-free?

A: Yes! Use:

Gluten-free soy sauce (like tamari)
Gluten-free flour or just use cornflour for coating

❓ Q: Can I use chicken instead of beef?

A: Absolutely. Thinly sliced boneless chicken thighs or breast work well. Follow the same steps.

❓ Q: Is this recipe spicy?

A: Mild to medium. You can:

Reduce fresh chilli or use none for milder
Add sriracha or chilli flakes for hotter

❓ Q: How do I reheat leftovers?

A: Air fryer at 180°C (350°F) for 3–4 minutes to re-crisp. Or pan-fry with a splash of oil. Avoid microwaving — it softens the crisp.

❓ Q: Can I meal prep this?

A: Yes, but for best texture:

Air fry the beef fresh
Make the sauce ahead (store in fridge up to 5 days)
Reheat sauce in a pan and toss fresh crispy beef when serving
