Ingredients You’ll Need

Here’s a breakdown of what you’ll need to make this crispy chilli beef magic happen:

For the Beef:

500g (1 lb) flank steak or sirloin, thinly sliced against the grain
½ cup cornstarch (for coating)
1 large egg white (to bind the coating)
Pinch of salt and black pepper
Oil for frying (vegetable or sunflower oil works well)

For the Sauce:

3 tablespoons sweet chilli sauce
1 tablespoon rice vinegar (or apple cider vinegar as a substitute)
1 tablespoon honey or brown sugar (for added stickiness)
2 tablespoons soy sauce
1 teaspoon sesame oil
1 teaspoon cornstarch mixed with 2 teaspoons water (slurry to thicken)

For Stir-Frying:

1 red bell pepper, sliced thin
1 green bell pepper, sliced thin
Fresh coriander or spring onions (for garnish)
1 medium onion, sliced
2 cloves garlic, minced
1 fresh red chili, thinly sliced (optional for extra heat)
1 tablespoon sesame seeds (for garnish)

Step-by-Step Instructions

1. Prepare the Beef

Slice your beef thinly against the grain—this ensures tenderness even after frying.
In a mixing bowl, add beef strips, egg white, cornstarch, salt, and pepper. Toss until the beef is evenly coated. The cornstarch will form a light batter around the meat, giving it that irresistible crunch once fried.

2. Fry Until Crispy

Heat oil in a wok or deep pan until it reaches around 180°C (350°F).
Fry the beef in small batches to avoid overcrowding. Each batch takes about 3–4 minutes until golden brown and crisp.
Place the fried beef strips on a paper towel to drain excess oil.

3. Make the Sauce

In a small bowl, mix together sweet chilli sauce, soy sauce, vinegar, honey, sesame oil, and the cornstarch slurry. Set aside.

4. Stir-Fry the Veggies

In a clean wok or skillet, heat a tablespoon of oil.
Add garlic, onion, and peppers. Stir-fry for 2–3 minutes until slightly softened but still vibrant and crisp.
Toss in sliced fresh chili for a fiery kick if you enjoy more heat.

5. Bring It All Together

Pour the prepared sauce into the wok and let it bubble until thickened and glossy.
Add the crispy beef strips and toss quickly to coat everything evenly in the sticky sauce.

6. Garnish and Serve

Sprinkle with sesame seeds and fresh coriander or spring onions.
Serve immediately while the beef is still crunchy and the sauce is sticky and hot.

Tips for Perfect Crispy Chilli Beef

Slice Thinly: Always cut against the grain into thin strips for tenderness.
Fry in Batches: Overcrowding the pan lowers oil temperature and makes beef soggy.
Double-Fry (Optional): For extra crunch, fry the beef once, let it cool, then fry again for 1–2 minutes.
Balance Flavors: Taste your sauce before adding the beef—adjust sweetness, saltiness, or spice as needed.
Serve Immediately: The longer the beef sits in sauce, the less crispy it becomes.

Serving Suggestions

Crispy chilli beef is versatile and pairs wonderfully with:

Steamed Jasmine Rice: A classic pairing that soaks up the flavorful sauce.
Fried Rice: Turn your meal into a full-on feast.
Stir-Fried Noodles: Toss with simple garlic noodles for a restaurant-style combo.
Vegetable Sides: Pair with stir-fried broccoli, bok choy, or snow peas for balance.

Variations to Try

Want to make this recipe your own? Here are some fun twists:

Spicier Version: Add more fresh red chili or a teaspoon of chili flakes to the sauce.
Sweeter Glaze: Increase the honey or brown sugar for a more caramelized effect.
Gluten-Free Option: Swap regular soy sauce with tamari or coconut aminos.
Different Proteins: Try the same method with chicken strips, prawns, or even tofu.
Veggie Boost: Add shredded carrots, baby corn, or snap peas for more crunch and nutrition.

Storing and Reheating

While crispy chilli beef is best enjoyed fresh, you can still save leftovers:

Storage: Keep in an airtight container in the fridge for up to 2 days.
Reheating: Use an oven or air fryer to re-crisp the beef. Microwave works, but it may lose crunch.
Meal Prep Tip: Store fried beef and sauce separately, then toss them together just before serving.

Nutritional Insights

This dish is indulgent, but when balanced with veggies and moderate portions, it can fit into a satisfying meal plan. Using lean cuts of beef and frying in clean oil helps reduce excess fat. If you prefer lighter versions, you can air-fry the beef or pan-sear with minimal oil instead of deep-frying.
