Ingredients You Need
-
Chicken
- 1.5 pounds boneless skinless chicken thighs or breasts, cut into 1 inch pieces
- 1 teaspoon kosher salt and 1 teaspoon black pepper
- 1 teaspoon garlic powder
- 1/2 cup cornstarch or potato starch for coating
- 2 tablespoons neutral oil like avocado or canola
-
Veg and fruit
- 1 red bell pepper and 1 green bell pepper, chopped into 1 inch pieces
- 1 small yellow onion, chopped
- 1 cup pineapple chunks, canned in juice works great — use the juice for the sauce
-
Sweet and sour sauce
- 1/2 cup pineapple juice from the can
- 1/3 cup ketchup (Heinz gives classic flavor)
- 1/4 cup rice vinegar or apple cider vinegar
- 1/4 cup light brown sugar or honey
- 3 tablespoons low sodium soy sauce or tamari
- 1 teaspoon grated fresh ginger
- 2 cloves garlic, minced
- 1 tablespoon cornstarch mixed with 1 tablespoon water
-
Finishing touches
- 1 teaspoon toasted sesame oil, optional
- Thinly sliced scallions and sesame seeds
- Red pepper flakes for a mild kick
Pantry shortcuts, brand notes, substitutions:
- Use pre-cut chicken from the butcher to save time.
- Frozen bell pepper strips and chopped onion work well straight from the freezer.
- Tamari keeps it gluten friendly. Coconut aminos cut sodium, so add a pinch more salt.
- Arrowroot thickens like cornstarch if that is what you have.
- Dole pineapple in juice gives consistent sweetness.
Equipment:
- Large rimmed sheet pan
- Parchment paper or foil
- Wire rack that fits the pan, optional but helps crisping
- Medium saucepan and whisk
- Mixing bowls, tongs, and a sharp knife
How to Make Oven-Baked Sweet and Sour Chicken Recipe
Heat the oven and prep the pan
- Heat oven to 425°F. Line a sheet pan with parchment. Set a wire rack on top if you have one and lightly oil it.
Season and coat the chicken
- Pat chicken dry. Toss with salt, pepper, and garlic powder. Add cornstarch and toss until every piece looks powdery and well coated. Drizzle oil and toss again so the coating looks slightly damp and clumpy.
Bake the chicken, round one
- Spread chicken in a single layer with space between pieces. Bake 15 to 18 minutes until the coating looks set and the edges turn golden. Stir the pieces once at the midpoint for even color.
Make the sweet and sour sauce
- While the chicken bakes, whisk pineapple juice, ketchup, rice vinegar, brown sugar, soy sauce, ginger, and garlic in a saucepan. Bring to a simmer over medium heat, then whisk in the cornstarch slurry. Simmer 1 to 2 minutes until glossy and thick enough to coat a spoon. Stir in sesame oil if using.
Sauce, add veggies, and finish in the oven
- Pull the pan from the oven. Add peppers, onion, and pineapple to the chicken. Pour the sauce over everything and toss right on the pan until every piece glistens. Return to the oven for 8 to 10 minutes until the peppers turn crisp-tender and the sauce bubbles.
Rest and garnish
- Let the pan rest 3 minutes so the sauce sets. Shower with scallions, sesame seeds, and a pinch of red pepper flakes. Serve hot.
Tips & Common Mistakes
- Dry the chicken well or the coating turns gummy.
- Give the cornstarch a light oiling so the crust browns in the oven.
- Space the chicken on the pan or steam will soften the crust.
- Warm the sauce until it bubbles or it will taste starchy.
- Cut peppers and onion to match the chicken size for even bites.
- Taste the sauce before finishing and balance it with a splash of vinegar or a teaspoon of sugar as needed.
- Use thighs if you want extra juicy results.
- Do not overbake after saucing or the coating softens too much.
Variations I've Tried
- Air fryer version: cook coated chicken at 390°F for 10 to 12 minutes, then toss with hot sauce and veg in a skillet for 2 to 3 minutes.
- Extra sticky: add 1 tablespoon apricot jam to the sauce.
- Spicy-sweet: swap ketchup to 1/4 cup ketchup plus 2 tablespoons gochujang.
- Orange twist: use orange juice instead of pineapple juice and add 1 teaspoon orange zest.
- Veg-forward: add snap peas or broccoli florets during the final bake.
How to Serve
Spoon the baked sweet and sour chicken over jasmine rice, brown rice, or cauliflower rice. I like a squeeze of lime for brightness and a sprinkle of sesame seeds for crunch. Pair with steamed broccoli or a quick cucumber salad to balance the richness. If you want noodles, toss lo mein or rice noodles with a splash of soy sauce and a little sesame oil, then top with the chicken.
Make-Ahead and Storage
Portion leftovers into airtight containers and chill within 2 hours. The chicken keeps in the fridge 3 to 4 days and in the freezer up to 3 months. Reheat on a sheet pan at 375°F for 10 to 12 minutes until hot and lightly crisp, or use a skillet over medium heat with a splash of water to loosen the sauce. Microwaves work for speed, though the coating softens, so I save that move for office lunches.

Ingredients
Instructions
- Preheat the oven to 325°F (165°C). Lightly grease a 9x13-inch baking dish.
- Season the chicken pieces with salt and black pepper. Place cornstarch in a shallow bowl and the beaten eggs in a separate shallow bowl.
- Dredge each piece of chicken in the cornstarch to coat, then dip into the beaten eggs, allowing excess to drip off.
- Heat the vegetable oil in a large skillet over medium-high heat. Sear the coated chicken in batches for 1–2 minutes per side until lightly golden but not cooked through. Transfer the browned chicken to the prepared baking dish.
- In a medium bowl, whisk together the sugar, ketchup, rice vinegar, soy sauce, and garlic powder until smooth.
- Pour the sweet and sour sauce evenly over the chicken in the baking dish. If using, scatter the chopped bell peppers and pineapple chunks over the top.
- Bake for 35–40 minutes, turning the chicken once or twice during baking to coat it well in the sauce, until the chicken is cooked through and the sauce is thickened and glossy.
- Remove from the oven and let rest for a few minutes. Garnish with sliced green onions and sesame seeds if desired, and serve hot over steamed rice.
