Oven-Baked Sweet and Sour Chicken Recipe tastes sticky, tangy, a little garlicky, and just crispy enough to make you forget about takeout. It works perfectly for busy weeknights, families, meal prep lovers, and it takes about 1 hour from start to finish. I tested versions of this in my tiny first apartment kitchen, and my smoke alarm and I both survived to tell the tale.

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

Ingredients You Need

Chicken

1.5 to 2 pounds boneless, skinless chicken breast or thighs, cut into 1 inch pieces
- Thighs stay juicier and more forgiving if you tend to overbake.
1 teaspoon fine sea salt
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon ground black pepper

Breading

1 cup cornstarch
- Cornstarch gives that classic light, crisp coating. You can use potato starch if you need a cornstarch swap.
2 large eggs, beaten
2 tablespoons neutral oil (canola, avocado, or grapeseed) for the pan
- Use a nonstick baking sheet or line with parchment to keep cleanup easy.

Sweet and Sour Sauce

1 cup pineapple juice
- Canned 100 percent juice from the pantry works great.
1/3 cup rice vinegar or apple cider vinegar
1/2 cup ketchup
- I like Heinz or a similar thick brand so the sauce clings well.
2/3 cup granulated sugar
- You can cut this to 1/2 cup if you prefer a less sweet sauce.
2 tablespoons low sodium soy sauce or tamari
1 tablespoon cornstarch mixed with 2 tablespoons cold water
1 teaspoon toasted sesame oil
2 cloves garlic, minced
1 teaspoon fresh ginger, grated, or 1/2 teaspoon ground ginger

Veggies and Extras

1 red bell pepper, cut into 1 inch pieces
1 green bell pepper, cut into 1 inch pieces
1 small yellow onion, cut into chunks
1 cup pineapple chunks, drained if canned
2 to 3 green onions, sliced, for garnish
Toasted sesame seeds, optional garnish
Cooked white rice, brown rice, or jasmine rice for serving

Equipment

Large mixing bowls
Whisk
Measuring cups and spoons
Large rimmed baking sheet
Parchment paper or a silicone baking mat
Tongs or a fork for coating chicken
Small saucepan for the sweet and sour sauce

Tips & Mistakes

Cut the chicken into even pieces so everything cooks at the same rate.
Pat the chicken dry before seasoning so the cornstarch sticks better.
Toss chicken in cornstarch right before baking so it stays crisp and does not turn gummy.
Do not crowd the baking sheet or the chicken will steam instead of crisp.
Preheat the oven fully so the coating sets quickly and does not soak up extra oil.
Stir the sauce constantly once it starts to bubble so it does not scorch.
Taste the sauce and adjust vinegar or sugar to match your sweet and sour preference.
Add veggies toward the end of baking so they stay a little crisp and keep their color.
Avoid overbaking the chicken or it will turn dry and chewy.
Let the chicken rest a few minutes before serving so the coating holds the sauce better.

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. Pat the chicken pieces dry with paper towels. Toss the chicken in a bowl with salt, garlic powder, onion powder, and black pepper until every piece looks coated.

Sprinkle the cornstarch over the seasoned chicken and toss until the pieces look evenly dusted and no dry piles of starch remain. Beat the eggs in a separate bowl. Dip each cornstarch coated piece into the egg, then place it on the prepared baking sheet, leaving a little space between pieces.

Step 2: Bake the chicken

Drizzle or lightly brush the chicken pieces with the neutral oil. Slide the baking sheet into the oven and bake for 15 minutes. Flip each piece with tongs, then bake another 10 to 12 minutes until the chicken looks golden and the internal temperature reaches 165°F.

If you want extra color, switch the oven to broil for 1 to 2 minutes at the end and watch closely so nothing burns. Set the baked chicken aside while you finish the sauce and veggies.

Step 3: Make the sweet and sour sauce

Add pineapple juice, vinegar, ketchup, sugar, soy sauce, garlic, and ginger to a small saucepan. Whisk everything together over medium heat until the sugar dissolves and the mixture starts to steam. Stir the cornstarch slurry again, then pour it into the saucepan while you whisk.

Keep whisking as the sauce bubbles and thickens to a glossy texture that coats the back of a spoon. Turn the heat to low, stir in the toasted sesame oil, and taste. Adjust with a splash more vinegar for extra tang or a teaspoon of sugar if you want more sweetness.

Step 4: Roast the veggies

While the sauce heats, spread the bell peppers, onion chunks, and pineapple on another lined baking sheet. Toss with a small drizzle of oil and a pinch of salt. Roast at 400°F for 8 to 10 minutes until the veggies soften slightly but still keep some crunch and bright color.

You can roast the veggies on the same sheet as the chicken during the last 10 minutes if your pan has room. Just keep the pieces in separate sections so you can stir them easily.

Step 5: Combine everything

Transfer the baked chicken to a large bowl or back into the baking pan. Add the roasted veggies and pineapple. Pour the hot sweet and sour sauce over the top.

Toss gently until every piece of chicken and every veggie looks glossy and coated. Sprinkle with sliced green onions and sesame seeds. Serve the oven-baked sweet and sour chicken over hot rice.

Variations I've Tried

Swap chicken for bite size pork pieces and follow the same method for a different take on sweet and sour. Use all pineapple juice and skip the bell peppers if you cook for picky eaters who side eye vegetables. Try a spicy version with a teaspoon of red pepper flakes or a spoonful of chili garlic sauce in the sweet and sour sauce.

Use cauliflower florets instead of chicken for a vegetarian spin and roast them until crisp before saucing. Stir in snap peas or broccoli florets during the last few minutes of roasting for extra crunch and color. Serve the sweet and sour chicken over cauliflower rice if you want a lighter base.

How to Serve Oven-Baked Sweet and Sour Chicken Recipe

Spoon the oven-baked sweet and sour chicken over fluffy white rice, brown rice, or jasmine rice so the grains soak up the extra sauce. Add a side of steamed broccoli, snap peas, or simple stir fried veggies to round out the meal. Kids usually love this with plain rice and extra pineapple chunks.

You can top each bowl with extra green onions and sesame seeds for a little crunch. If you pack lunches, portion the chicken and rice into containers and add some cucumber slices or carrot sticks on the side.

How to store

Cool leftovers to room temperature within 1 hour, then store in an airtight container in the fridge for up to 4 days.
Freeze portions of sweet and sour chicken in freezer safe containers for up to 2 months, and label with the date so you do not lose track.
Reheat in a skillet over medium heat with a splash of water or pineapple juice until hot, which keeps the sauce glossy and the chicken tender.
Use the microwave in short bursts if you feel impatient, and stir between bursts so the chicken heats evenly and does not dry out.
