Oven-Baked Sweet and Sour Chicken Recipe tastes sticky, tangy, a little garlicky, and just crispy enough to feel like takeout without the deep fryer. It works for busy weeknights, family dinners, or meal prep, and you can get it on the table in about 1 hour including oven time. I tested this version so many times that my kids now rate chicken on a “sweet and sour scale,” which feels like both a win and a problem.

Why Make This Oven-Baked Sweet and Sour Chicken Recipe at Home

You control the ingredients, so the sauce tastes bright and fresh instead of cloyingly sweet. You also skip deep frying, which keeps the kitchen cleaner and the recipe a bit lighter while still giving you that sticky, caramelized coating.

You can tweak the flavor to match your mood: extra tangy, extra sweet, or extra spicy. Leftovers reheat beautifully, so you get a takeout-style meal that stretches into lunch the next day without turning soggy and sad.

Better than our local takeout spot, this oven-baked sweet and sour chicken recipe hits the perfect balance of crispy, saucy, and tangy-sweet perfection. ★★★★★

Ingredients You Need

Chicken

1.5 to 2 pounds boneless skinless chicken breasts
- Cut into 1-inch pieces for faster cooking and better sauce coverage.
- You can use boneless skinless thighs for juicier bites and slightly richer flavor.
2 large eggs
- Beat them in a shallow bowl to help the coating stick.
1 cup cornstarch
- Cornstarch gives a light, crisp coating in the oven.
- You can use arrowroot starch in a pinch, but cornstarch browns better.
1 teaspoon kosher salt
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon ground black pepper
2 to 3 tablespoons neutral oil
- Use canola, avocado, or grapeseed oil.
- Avoid strong oils like extra virgin olive oil, which can taste bitter at high heat.

Sweet and Sour Sauce

1 cup pineapple juice
- Use canned 100 percent juice from a small can; it keeps well in the pantry.
1/2 cup ketchup
- A standard American brand works great; no need for fancy stuff.
1/2 cup rice vinegar
- Use unseasoned rice vinegar so you control the salt and sugar.
1/2 cup light brown sugar, packed
- Brown sugar gives a deeper flavor than white sugar.
2 tablespoons low sodium soy sauce
- Low sodium helps you season to taste at the end.
2 cloves garlic, minced
1 teaspoon fresh ginger, grated
- Use a microplane or the small side of a box grater.
- In a pinch, use 1/2 teaspoon ground ginger.
1 tablespoon cornstarch mixed with 2 tablespoons cold water
- This slurry thickens the sauce in the oven.

Veggies and Add-ins

1 red bell pepper, cut into 1-inch pieces
1 green bell pepper, cut into 1-inch pieces
1 small yellow onion, cut into 1-inch chunks
1 cup pineapple chunks
- Use canned pineapple chunks in juice for convenience.
2 to 3 green onions, thinly sliced, for garnish
1 tablespoon toasted sesame seeds, optional

Pantry Shortcuts and Notes

Use pre-minced garlic and ginger from a jar if you need a shortcut.
Frozen bell pepper strips work; add them straight from the freezer.
If you avoid soy, use coconut aminos and reduce the brown sugar slightly.

Equipment List

Large rimmed baking sheet
Parchment paper or a silicone baking mat
Two medium bowls (one for eggs, one for cornstarch)
Small saucepan
Whisk
Tongs or a spatula
Instant-read thermometer, helpful but optional

Tips & Mistakes

Cut chicken into even pieces so everything cooks at the same rate.
Pat chicken dry before coating so the cornstarch sticks and crisps.
Toss chicken in cornstarch right before baking so it does not turn gummy.
Do not crowd the pan; leave a little space between pieces so they brown.
Flip the chicken halfway through baking so both sides crisp.
Stir the sauce ingredients well before you add the cornstarch slurry so no clumps form.
Taste the sauce before baking with the chicken; adjust sugar or vinegar to your liking.
Add veggies in larger chunks so they stay slightly crisp, not mushy.
Do not overbake; pull the chicken at 165°F internal temperature for juicy bites.
Line the pan with parchment for easier cleanup and less sticking.

How to Make Oven-Baked Sweet and Sour Chicken Recipe

Step 1: Prep the Chicken

Preheat your oven to 400°F and line a large rimmed baking sheet with parchment.
Cut the chicken into 1-inch pieces and pat them dry with paper towels.
In one bowl, beat the eggs; in another bowl, mix cornstarch, salt, garlic powder, onion powder, and black pepper.

Dip each piece of chicken into the egg, then coat it in the seasoned cornstarch.
Place the coated chicken pieces on the prepared baking sheet in a single layer.
Drizzle or lightly brush the chicken with the neutral oil so the coating crisps in the oven.

Step 2: Bake the Chicken

Place the baking sheet on the middle rack.
Bake the chicken for 15 minutes, then flip each piece with tongs.
Bake another 10 to 15 minutes until the coating looks lightly golden and the chicken reaches 165°F inside.

While the chicken bakes, prep your veggies and sauce.
Cut the bell peppers and onion into 1-inch pieces and set them aside.
Drain the pineapple chunks if you use canned fruit and pat them dry so they do not water down the sauce.

Step 3: Mix the Sweet and Sour Sauce

In a small saucepan, whisk together pineapple juice, ketchup, rice vinegar, brown sugar, soy sauce, garlic, and ginger.
Bring the mixture to a gentle simmer over medium heat, whisking often.
In a small cup, stir the cornstarch and cold water until smooth, then pour it into the simmering sauce while you whisk.

Keep whisking until the sauce thickens and turns glossy, about 1 to 2 minutes.
Turn off the heat and taste the sauce.
Add a pinch of salt, more brown sugar, or a splash of vinegar to match your ideal sweet and sour balance.

Step 4: Combine Chicken, Veggies, and Sauce

Reduce the oven temperature to 375°F.
Scatter the bell peppers, onion, and pineapple chunks around the baked chicken on the same pan.
Pour the thickened sweet and sour sauce evenly over everything and toss gently with a spatula to coat.

Spread the mixture back into a single layer.
Return the pan to the oven and bake for 10 to 15 minutes.
Stir once halfway through so the sauce caramelizes slightly around the edges and coats every piece.

Step 5: Finish and Garnish

Pull the pan from the oven when the veggies turn tender-crisp and the sauce bubbles.
Let the chicken rest on the pan for 5 minutes so the sauce thickens a bit more.
Sprinkle sliced green onions and toasted sesame seeds over the top.

Taste one piece and adjust seasoning with a tiny splash of soy sauce or a pinch of salt if needed.
Serve hot over rice or your favorite base.
Try not to eat half the pan while you “taste test,” which I say from experience.

Variations I've Tried

Use boneless skinless chicken thighs instead of breasts for extra juicy, slightly richer bites.
Swap half the ketchup with chili garlic sauce or sriracha for a spicy sweet and sour chicken that still bakes in the oven.
Add broccoli florets or snap peas in the last 10 minutes of baking for more veggies and color.

Use cauliflower florets in place of chicken for a vegetarian twist; roast them until crisp, then toss with the sauce.
Replace pineapple juice with orange juice for a citrusy version that tastes like sweet and sour meets orange chicken.
Use gluten free tamari and a gluten free ketchup to keep the recipe fully gluten free.

How to Serve Oven-Baked Sweet and Sour Chicken Recipe

Serve this oven-baked sweet and sour chicken recipe over hot steamed jasmine or basmati rice for a classic takeout-style plate. You can spoon it over brown rice or cauliflower rice if you want more fiber or fewer carbs. Add a side of steamed broccoli, green beans, or a simple cucumber salad for crunch and freshness.

Top each serving with extra green onions and sesame seeds for texture and color. Kids usually love the sweet sauce, so this dish often becomes a family favorite without much negotiation at the table. If you pack it for lunch, keep the rice and chicken separate so the sauce stays thick and glossy.

How to store

Fridge: Cool leftovers to room temperature within 30 minutes, then store the chicken and sauce in an airtight container in the fridge for up to 4 days.
Freezer: Portion cooled chicken and sauce into freezer-safe containers or bags, squeeze out extra air, and freeze for up to 2 months.
Reheating (best method): Reheat in a skillet over medium heat with a splash of water until hot and bubbly, about 5 to 7 minutes, and stir often so the sauce loosens and coats the chicken again.
Microwave option: Reheat in a microwave-safe dish in 45 to 60 second bursts, stirring between each burst, until hot; add a teaspoon of water if the sauce looks too thick.
