Instructions
1. Prepare the chicken
Place the cut chicken in a large bowl and combine with salt, pepper, garlic powder, chilli powder, cornflour, baking soda and egg. Mix thoroughly and let this marinate as you prep the rest.
2. Prep the vegetables and make the sauce
Chop up the vegetables ready for cooking. In a small bowl, combine the vinegar, ketchup, soy sauce, sugar, and pineapple juice. Stir until the sugar dissolves. Prepare the cornstarch slurry and set aside.
3. Cook the chicken
Dredge the marinated chicken in a light dusting of cornflour just before cooking. Fry in batches until golden brown and crispy, about 4-5 minutes per batch. Remove and drain on paper towels. Alternatively, air fry at 200°C (400°F) for 10-12 minutes, flipping halfway.
4. Stir-Fry the Veggies
In a large wok, heat oil over medium heat. Add the bell peppers and onion, stir-frying for 3-4 minutes. Toss in the pineapple chunks and cook for 2 more minutes. Pour the sweet and sour sauce over everything, then stir in the cornflour slurry.
5. Add the chicken and serve
Add the crispy chicken to the wok. Toss to coat everything evenly. Serve immediately with steamed white rice or fried rice.
FAQs
Can I use a different type of chicken?
Yes! While this recipe uses chicken breast or thighs, you can easily swap them for your preferred cut. Just make sure to adjust cooking time accordingly.
Can I make the sauce ahead of time?
Absolutely! You can prepare the sweet and sour sauce in advance and store it in the fridge for up to a week.
Can I make this recipe gluten-free?
Yes — substitute the soy sauce with tamari and use a gluten-free flour or cornstarch for the batter. Check all other labels too.
How can I make the chicken extra crispy?
Make sure the oil is hot enough before frying (around 350°F/175°C). Don't overcrowd the pan, and you can double-coat the chicken for extra crunch.
Can I use other vegetables in the dish?
Definitely! While the traditional recipe includes bell peppers, onions, and pineapples, feel free to add carrots, zucchini, or snap peas.
How spicy is this recipe?
This recipe is not inherently spicy. If you like heat, add some red pepper flakes or chopped fresh chilli peppers to the sauce.
How long will leftovers last?
Leftover sweet and sour chicken can be stored in an airtight container in the fridge for up to 3 days. Reheat in a hot skillet for the best results.
