This baked sweet and sour chicken is a crispy, oven-finished version of your favorite takeout, with golden bites coated in a glossy homemade sauce.
If you crave that sticky, tangy takeout chicken but don’t want to deep-fry, this baked sweet and sour chicken is a perfect fit for your kitchen. Cubes of tender chicken are lightly coated, pan-seared, then finished low and slow in the oven until they’re coated in a thick, clingy sauce.
The beauty of this dish is how simple the ingredient list really is. You’re using pantry staples like sugar, vinegar, ketchup, and soy sauce to build layers of flavor that taste surprisingly restaurant-worthy. Serve it over a bowl of fluffy rice and you’ve got a colorful, crowd-pleasing dinner everyone recognizes and loves.
Once you’ve made it once, you’ll find it’s a go-to for busy evenings, casual weekends, or even laid-back entertaining. You can leave the chicken to bake while you cook rice and quickly sauté some vegetables, so everything comes together with very little last-minute stress.
Baked Sweet and Sour Chicken Recipe Ingredients
This dish starts with bite-size pieces of chicken and a light coating that bakes up beautifully in the oven, all drenched in that classic sweet-tangy sauce. Here’s what each core ingredient brings to the pan.
- Boneless skinless chicken breasts – cut into small cubes so they cook quickly, stay juicy, and soak up the sauce.
- Cornstarch – creates a thin coating that helps the chicken brown and also helps the sauce cling and thicken.
- Eggs – bind the cornstarch to the chicken so the coating doesn’t fall off while browning and baking.
- Vegetable oil – used for a quick pan-sear, adding flavor and a touch of crispness without deep-frying.
- Salt and black pepper – simple seasoning that ensures the chicken itself tastes good before you add the sauce.
- Granulated sugar – balances the vinegar and gives the sauce its glossy, sweet backbone.
- Apple cider or white vinegar – provides that bright, tangy “sour” note; cider vinegar adds a slightly fruitier flavor.
- Ketchup – adds tomato richness, body, and that familiar sweet-and-savory profile with a rosy color.
- Soy sauce – brings in salty, savory depth and keeps the sauce from tasting one-dimensional.
- Garlic powder and onion powder – quick, reliable flavor boosters that add aromatic warmth without chopping fresh aromatics.
Step-by-Step Baked Sweet and Sour Chicken
Once everything is prepped, this baked sweet and sour chicken comes together in just a few straightforward stages.
STEP 1: Preheat your oven to 325°F (160°C). Lightly grease a 9×13-inch baking dish so the chicken doesn’t stick. Pat the chicken cubes dry with paper towels, then season them evenly with salt and black pepper.
STEP 2: Place the cornstarch in a shallow bowl and the beaten eggs in another. Toss the seasoned chicken in the cornstarch until each piece is lightly coated, then dip the coated pieces into the eggs so they’re fully covered.
STEP 3: Heat the vegetable oil in a large skillet over medium-high heat. Working in batches, sear the chicken cubes until lightly golden on each side. You’re just browning the outside here, not cooking them through. Transfer the browned pieces into the prepared baking dish.
STEP 4: In a medium bowl, whisk together the sugar, vinegar, ketchup, soy sauce, garlic powder, and onion powder until smooth and well combined. The mixture should be glossy and pourable, with a strong sweet-and-tangy aroma.
STEP 5: Pour the sauce evenly over the chicken in the baking dish, gently tossing so everything is coated. Bake uncovered for 50–60 minutes, turning the chicken every 15 minutes so the sauce thickens, reduces, and clings to each piece.
STEP 6: When the chicken is cooked through and the sauce is thick and bubbling, remove the dish from the oven. Let it sit for a few minutes, then toss again so every piece is glossy. Serve hot over steamed rice with your favorite vegetables, spooning extra sauce over the top.
Pro Tips for Baked Sweet and Sour Chicken
A few small details will help this baked sweet and sour chicken taste just as good as your favorite takeout, with less fuss and cleanup.
- Dry the chicken really well. Patting it dry before coating means the cornstarch sticks better and browns nicely instead of turning gummy in the pan.
- Brown in batches. If you crowd the skillet, the chicken steams instead of sears. Give the pieces space so they take on good color and flavor.
- Adjust the sauce to taste. Want it tangier? Add a splash more vinegar. Prefer sweeter? Stir in a spoonful of sugar. Remember the sauce will taste less sharp once it bakes.
Can I use chicken thighs instead of breasts?
Yes, boneless skinless chicken thighs work beautifully here. They stay extra juicy and add a richer flavor. Just keep the pieces similar in size and bake until they’re fully cooked through.
How can I make the sauce less sweet?
You can reduce the sugar slightly and increase the vinegar by a tablespoon or two. A small splash of water will also soften the sweetness without changing the texture too much.
Can I add vegetables or pineapple to the dish?
Absolutely. Stir in bell pepper strips, onion wedges, or pineapple chunks during the last 20–25 minutes of baking. That way they heat through, soften slightly, and soak up the sauce without turning mushy.
Can I make this baked sweet and sour chicken ahead of time?
You can bake it earlier in the day, cool, and refrigerate. The coating softens slightly, but the flavors deepen. Reheat gently in the oven so the sauce loosens and warms through before serving.
Serving Ideas for Baked Sweet and Sour Chicken
This baked sweet and sour chicken begs for a base that will soak up all that extra sauce. Steamed white rice, jasmine rice, or even brown rice all work wonderfully. If you’re making a bigger spread, simple fried rice is a fun option too.
For color and crunch, serve it alongside stir-fried or roasted vegetables like broccoli, snap peas, carrots, or bell peppers. A crisp cucumber salad or a simple Asian-style slaw adds freshness and cuts through the richness. Egg rolls or spring rolls on the side turn it into a full takeout-style feast.
How to Store & Reheat
Let any leftovers cool to room temperature, then transfer the chicken and sauce to an airtight container. Refrigerate for up to 3–4 days. The sauce will thicken as it chills, which is normal, and actually helps keep the chicken moist.
To reheat, warm the chicken and sauce together in a baking dish at about 300–325°F (150–160°C) until hot, stirring once or twice. You can also use a skillet over low heat with a splash of water if the sauce feels too thick. For longer storage, freeze portions in freezer-safe containers for up to 2–3 months, then thaw overnight in the fridge before reheating.
