Ingredients

(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the Beef:

200 g rump or sirloin steak (or any tender steak cut)
1 egg
1 cup cornstarch or potato starch

For the Marinade:

1 tablespoon light soy sauce
1 teaspoon ginger garlic paste
1 teaspoon sesame oil
½ teaspoon sugar
¼ teaspoon white pepper

For the Stir-Fry Sauce:

3 tablespoon sweet chilli sauce
2 tablespoon ketchup
2 tablespoon light soy sauce
1 teaspoon vinegar (white or rice)
1 tablespoon sugar
½ teaspoon salt

Vegetables:

½ sweet onion
½ bell pepper
2-3 spring onions
2-3 bird’s eye or hot chillies

Directions

Marinate the Beef: I slice the beef thinly against the grain, then mix it with soy sauce, ginger garlic paste, sesame oil, sugar, and white pepper. I let it marinate for at least 15 minutes.
Prepare the Sauce: I combine sweet chilli sauce, ketchup, soy sauce, vinegar, sugar, and salt in a bowl and set it aside.
Coat the Beef: I add an egg to the marinated beef and mix well. Then I coat the beef strips with cornstarch, making sure they’re well covered and not clumped together.
Fry the Beef: In hot oil (around 175°C or 350°F), I fry the coated beef in batches until it’s golden brown and crispy. Then I drain them on a cooling rack or paper towels.
Stir-Fry the Vegetables: In a hot pan or wok with a little oil, I stir-fry onions and bell peppers for about 1-2 minutes, just until slightly tender.
Combine Everything: I toss the crispy beef into the pan with the vegetables, pour in the sauce, and stir-fry everything together for another 1-2 minutes. Then I add spring onions and sliced chillies for the final touch.

Variations

Different Proteins: I sometimes swap the beef for chicken, shrimp, or tofu for a twist.
Extra Veggies: Adding carrots, broccoli, or snow peas makes it more colorful and nutritious.
Make It Spicier: I throw in more chillies or even a bit of chilli oil when I want more heat.
Low-Sugar Option: I reduce the sugar in the sauce and use a sugar-free ketchup when cutting back on sweetness.

Storage/Reheating

Storage: I store leftovers in an airtight container in the fridge for up to 3 days.
Reheating: To keep the beef crispy, I reheat it in the oven or air fryer. The microwave works, but it softens the coating.

FAQs

How do I keep the beef crispy after frying?

I keep it crisp by frying in small batches and draining it well. When storing or reheating, I avoid covering it tightly so it doesn’t steam.

Can I make this recipe ahead of time?

I prepare the sauce and marinate the beef ahead, but I fry the beef fresh right before serving to keep it crispy.

What cut of beef should I use?

I like to use rump or sirloin steak. Thinly slicing it against the grain helps keep it tender after frying.

Is this dish very spicy?

It depends on the type and amount of chillies. I can easily control the spice by adding fewer chillies or using a mild sweet chilli sauce.

Can I bake the beef instead of frying?

I can bake it at a high temperature (around 220°C/425°F) on a wire rack until crispy, though it won’t be quite as crunchy as deep-fried.

Conclusion

Crispy Sweet Chilli Beef is a quick and flavorful dish that’s perfect when I’m craving something bold and satisfying. The crispy texture of the beef with that sticky, spicy-sweet sauce makes this recipe a winner every time. It’s simple, delicious, and sure to impress!
