Air fryer chilli beef gives you the crisp texture of deep-fried beef without excess oil. The beef turns golden and crunchy, then gets coated in a glossy, sweet-spicy sauce with garlic, soy, and fresh chilli.
This recipe is written clearly and thoroughly so you can achieve restaurant-quality results at home.
Ingredients (Serves 3–4)
For the Beef
- 500 g flank steak or sirloin, thinly sliced into strips
- 3 tablespoons cornflour (cornstarch)
- 1 tablespoon light soy sauce
- 1 teaspoon sesame oil
- 1 egg white
- ½ teaspoon salt
- ½ teaspoon black pepper
- Cooking oil spray
For the Chilli Sauce
- 2 tablespoons light soy sauce
- 1 tablespoon dark soy sauce
- 2 tablespoons sweet chilli sauce
- 1 tablespoon rice vinegar
- 1 tablespoon honey or brown sugar
- 2 cloves garlic, minced
- 1–2 red chillies, thinly sliced
- 1 teaspoon grated fresh ginger
- 3 tablespoons water
- 1 teaspoon cornflour mixed with 1 tablespoon water (slurry)
Optional Garnish
- Spring onions, sliced
- Sesame seeds
Step 1: Prepare the Beef Properly
Thin slicing is crucial. Place the beef in the freezer for 20–30 minutes before cutting. This firms the meat and makes it easier to slice very thinly.
Cut against the grain into strips about ½ cm thick.
Thin strips ensure tenderness and crisp texture.
Step 2: Marinate for Flavor and Tenderness
In a large bowl, combine:
- Soy sauce
- Sesame oil
- Egg white
- Salt and pepper
Add the sliced beef and mix thoroughly.
Let it marinate for at least 20 minutes.
This step keeps the beef juicy inside while allowing the coating to stick.
Step 3: Coat for Crispiness
Add cornflour directly to the marinated beef.
Mix until every strip is fully coated.
The surface should look slightly dry and powdery.
Do not add extra liquid at this stage.
Step 4: Air Fry to Perfection
Preheat your air fryer to 200°C (400°F) for 3–5 minutes.
Arrange beef strips in a single layer in the basket.
Do not overcrowd. Cook in batches if necessary.
Lightly spray with oil.
Air fry for:
- 8–10 minutes total
- Shake halfway through
The beef should look golden brown and crisp around the edges.
If needed, cook for 2–3 extra minutes for deeper crispness.
Remove and set aside.
Step 5: Make the Chilli Sauce
In a small saucepan over medium heat:
- Add garlic and ginger. Cook 30 seconds until fragrant.
- Stir in soy sauces, sweet chilli sauce, vinegar, honey, and water.
- Bring to a gentle simmer.
- Add sliced chillies.
- Stir in the cornflour slurry.
Simmer for 1–2 minutes until thick and glossy.
The sauce should coat the back of a spoon.
Step 6: Combine Without Losing Crispiness
Place the crispy beef in a large bowl.
Pour the hot sauce over it.
Toss quickly and gently until evenly coated.
Serve immediately to maintain crunch.
Texture Tips for Best Results
- Slice thinly and evenly.
- Avoid overcrowding the air fryer basket.
- Spray lightly with oil to encourage browning.
- Add sauce just before serving.
Spice Level Control
Mild: Use only sweet chilli sauce and remove fresh chillies.
Medium: Use one fresh chilli.
Hot: Add extra chillies or a pinch of chilli flakes.
What to Serve With
- Steamed jasmine rice
- Egg fried rice
- Stir-fried noodles
- Steamed broccoli or pak choi
Storage
Refrigerate leftovers for up to 2 days.
Reheat in the air fryer at 180°C for 3–4 minutes.
Note: The coating will soften after refrigeration but will crisp slightly when reheated.
Make It Even Better
For restaurant-style texture, you can double air fry:
- First cook: 6–7 minutes
- Rest 3 minutes
- Second cook: 3–4 minutes
This gives extra crunch before adding the sauce.
