How to Make Sweet and Sour Chicken
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Have a large ovenproof dish ready and place a shelf in the middle of the oven.
- Mix the sauce: In a jug, stir together the pineapple juice, ketchup, rice vinegar, soy sauce and brown sugar. In a separate small bowl, mix the cornflour with the cold water until smooth, then stir it into the sauce.
- Brown the chicken: Heat the oil in a large frying pan over medium-high heat. Add the chicken and cook for 4 to 5 minutes, turning occasionally, until lightly browned. It does not need to be cooked through at this stage. Transfer it to the ovenproof dish.
- Cook the vegetables: Add the onion and peppers to the same pan and cook for 3 minutes, stirring. Add the garlic and ginger and cook for 30 seconds more. Spoon the vegetables into the dish with the chicken.
- Add the sauce and pineapple: Stir the sauce again to redistribute the cornflour, then pour it into the dish. Add the pineapple chunks and stir everything together.
- Bake: Bake uncovered for 20 to 25 minutes, stirring halfway through, until the sauce is bubbling and thickened. The chicken should be cooked through and reach 75°C in the thickest pieces.
- Rest and serve: Leave the dish to stand for 5 minutes before serving. Stir once more, then spoon the chicken and sauce over warm rice.

Tips for the Best Sweet and Sour Chicken
How do I keep the chicken tender?
Cut the chicken into similarly sized pieces so they cook evenly. Brown them briefly before baking, then check for doneness towards the end of the cooking time.
How can I make the sauce thicker?
The sauce should thicken as it bubbles in the oven. If it is still too thin, transfer it to a pan and simmer for a few minutes, stirring frequently.
How do I stop the vegetables becoming too soft?
Cut the peppers and onion into generous bite-sized pieces and cook them only briefly in the frying pan. They will soften further in the oven.
Can I adjust the sweetness or tanginess?
Yes. Taste the cooked sauce and add a little extra sugar for sweetness or a splash of rice vinegar for more tang. Stir well before serving.
Serving Suggestions
- Serve with steamed basmati or jasmine rice.
- Add egg noodles for a quick alternative to rice.
- Pair with steamed broccoli or green beans.
- Scatter sliced spring onions over the top for a fresh finish.
Storage and Reheating
Room temperature
Do not leave cooked chicken at room temperature for more than 2 hours. Divide leftovers into shallow containers so they cool quickly, then refrigerate.
Refrigerator
Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in a pan or microwave until piping hot throughout, adding a splash of water if the sauce has thickened. Reheat only once.
Freezing
Freeze cooled portions in airtight, freezer-safe containers for up to 3 months. Defrost overnight in the fridge, then reheat until piping hot throughout. The peppers may be softer after freezing.

FAQs
Can I use chicken thighs instead of chicken breasts?
Yes. Use the same weight of boneless, skinless chicken thighs and cut them into even pieces. Bake until the thickest pieces reach 75°C.
Can I make sweet and sour chicken without pineapple?
Yes. Replace the pineapple juice with unsweetened apple juice and leave out the pineapple chunks. Taste the cooked sauce and adjust the vinegar or sugar if needed.
Can I make this recipe ahead of time?
Yes. Cook the dish, cool it promptly and refrigerate it in an airtight container for up to 3 days. Reheat until piping hot throughout.
Can I cook sweet and sour chicken on the hob?
Yes. After browning the chicken and softening the vegetables, add the sauce and pineapple to the pan. Simmer gently, stirring occasionally, until the sauce thickens and the chicken reaches 75°C.
Is this sweet and sour chicken gluten-free?
It can be if you use gluten-free soy sauce and check that the cornflour, ketchup and other packaged ingredients are labelled gluten-free.
