This Baked Sweet and Sour Chicken is a delicious homemade version of the classic Chinese takeout favorite. The chicken pieces are lightly coated, baked until golden and crispy, and then tossed in a glossy sweet and sour sauce that perfectly balances tangy and sweet flavors.
Unlike many baked versions, the chicken stays crispy on the outside and juicy on the inside, while the sticky sauce coats every bite beautifully.
It’s the perfect recipe when you’re craving takeout-style comfort food but want something a little lighter and easy to make at home.
Why This Recipe Works
I won’t claim this is the “best sweet and sour chicken ever” — taste is always personal — but this version is definitely one of my favorites for several reasons.
It isn’t overly sweet
Many sweet and sour sauces contain up to a full cup of sugar. This recipe uses only half a cup, which still gives the sauce its signature sweetness but keeps it from becoming overpowering.
It has a balanced tang
Sweet and sour sauce should have a bright, slightly tart flavor without making you wince from too much acidity. This version is pleasantly tangy rather than sharply sour.
The sauce tastes like restaurant sauce
A lot of homemade sweet and sour sauces feel like they’re missing something. The secret is adding a few extra ingredients that create depth and umami:
- Worcestershire sauce
- soy sauce
- oyster sauce
These ingredients transform the sauce from simple to restaurant-quality.
The chicken is actually crispy
While oven-baked chicken can never be quite as crispy as deep-fried chicken, this method gets surprisingly close.
The chicken stays juicy
Some recipes bake the chicken for 45 minutes or more, which can easily dry it out. This recipe bakes the chicken for just 15–20 minutes, which keeps it tender and moist.
A Secret Ingredient: Pineapple Juice
A small splash of pineapple juice from canned pineapple adds a subtle fruity sweetness that gives the sauce that classic Chinese takeout flavor.
It’s a small detail, but it really makes a difference.

How to Make Baked Sweet and Sour Chicken
Step 1 – Preheat the oven
Preheat your oven to 200°C / 390°F.
Step 2 – Coat the chicken
Place the chicken pieces in a bowl and sprinkle with salt.
Add the beaten egg and mix well so the chicken is fully coated. Drain any excess egg.
Place the chicken in a zip-top bag with the cornstarch and shake until each piece is coated.
Step 3 – Lightly brown the chicken
Heat oil in a large skillet over high heat.
Cook the chicken for about 2 minutes, turning occasionally so the outside becomes lightly golden and slightly crisp.
The chicken should still be raw inside at this stage.
Step 4 – Bake the chicken
Transfer the chicken to a baking tray.
Spray lightly with oil and bake for 15–20 minutes, until golden and crispy.
Making the Sweet and Sour Sauce
While the chicken bakes, prepare the sauce.
Step 1 – Cook the vegetables
In the same skillet, wipe away excess oil.
Add a small amount of fresh oil and cook the garlic for about 20 seconds.
Add the onion and cook for 2 minutes, then add the bell peppers and cook for another minute.
Step 2 – Add the sauce ingredients
Stir in:
- sugar
- vinegar
- pineapple juice
- ketchup
- Worcestershire sauce
- soy sauce
- oyster sauce
- salt
Bring the mixture to a gentle simmer until the sugar dissolves.
Step 3 – Thicken the sauce
Mix the cornstarch and water together, then add it to the pan.
Stir constantly until the sauce thickens into a glossy, syrupy consistency.
Add the pineapple chunks and stir just to warm them through.
Combine the Chicken and Sauce
Once the chicken is done baking, add it to the skillet with the sauce.
Toss gently until all the pieces are coated in the sweet and sour glaze.
Serve immediately for the best texture.
Serving Suggestions
Sweet and sour chicken pairs perfectly with:
- steamed white rice

You can also garnish with:

Tips for the Best Results
Don’t overcook the chicken
The key to juicy chicken is a shorter baking time.
Use the full sauce ingredient list
The Worcestershire, soy sauce, and oyster sauce create that authentic takeout-style flavor.
Add pineapple juice
This enhances the fruitiness and balances the tangy vinegar.
Serve immediately
The chicken stays crispiest when served right after being coated in the sauce.
