Ingredients You’ll Need

1 lb boneless skinless chicken breast: Cut into bite-size pieces. This lean protein keeps the dish light while absorbing all those delicious flavors.
2 tbsp cornstarch: Used for coating the chicken, ensuring a crispy exterior during searing. For a gluten-free option, you can swap with arrowroot powder.
1 tbsp cooking oil: Choose a high-heat oil like canola or vegetable oil for frying without burns.
1 bell pepper: Chopped. This adds a fresh crunch and vibrant color; feel free to use any color you have on hand.
1 cup pineapple chunks: Optional but recommended for a sweet burst. If you want to streamline, canned pineapple works great.
½ cup lemon juice: You can substitute with pineapple juice for a sweeter taste profile, enhancing the tropical flavor.
¼ cup brown sugar: This gives the sauce a rich sweetness; light or dark brown sugar will work.
3 tbsp ketchup: Adds depth and a hint of tang to the sauce; a pantry staple that rounds out the flavor.
2 tbsp rice vinegar: Although white vinegar is a fine option, rice vinegar brings a gentler acidity.
1 tbsp soy sauce: For that umami kick; low-sodium soy sauce works well if you’re watching salt intake.
1 tsp garlic powder: A quick way to infuse garlicky goodness into the sauce.
1 tsp cornstarch: Mixed for thickening the sauce as it bakes.

How to Make Baked Sweet and Sour Chicken

Preheat the oven: Set your oven to 350°F to get it hot while you prepare the chicken.
Prepare the chicken: Cut 1 lb boneless skinless chicken breast into bite-size pieces and toss them with 2 tbsp cornstarch until they are evenly coated. This will give the chicken a wonderful crispiness during cooking.
Make the sauce: In a bowl, whisk together ½ cup pineapple juice (or lemon juice), ¼ cup brown sugar, 3 tbsp ketchup, 2 tbsp rice vinegar, 1 tbsp soy sauce, 1 tsp garlic powder, and 1 tsp cornstarch until smooth. This is your sweet and sour goodness waiting to happen.
Sear the chicken: Heat 1 tbsp cooking oil in a large oven-safe skillet over medium-high heat. Add the coated chicken and sear for 30-60 seconds per side, just until lightly golden. This step is crucial for locking in that juicy flavor.
Add bell pepper and pineapple: Stir in 1 chopped bell pepper and 1 cup pineapple chunks (if using), combining everything in the pan perfectly.
Pour the sauce: Pour the previously made sauce over the chicken and stir to coat evenly. Don’t skip this step! The chicken should be entirely submerged in that luscious sauce.
Bake: Transfer the skillet to the oven and bake for 25-30 minutes, stirring halfway through. The sauce will thicken, and you’ll want to ensure the chicken reaches an internal temperature of 165°F.
Serve: Serve your creation over cooked white rice or noodles, garnishing with green onions or sesame seeds if desired. Enjoy the celebration of flavors coming together in one delightful dish!

Storing & Reheating

Leftovers can be stored in an airtight container in the refrigerator, where they’ll last for up to 4 days. If you want to keep them longer, consider freezing the chicken in a freezer-safe dish for up to 3 months. When you’re ready to eat, simply thaw in the refrigerator overnight, then reheat in a skillet over low heat or in the microwave until warmed through. The sauce may thicken during storage, so a splash of water can help refresh it as you reheat.

Chef’s Helpful Tips

Avoid overcooking the chicken to keep it juicy; check for doneness at the 25-minute mark.
For a crispy topping, broil the dish for the last 3 minutes of baking; just watch closely to avoid burning.
Customize your veggies! Snow peas, broccoli, or even carrots can add extra nutrition and color.
For extra flavor, marinate the chicken in the sauce for an hour or overnight before cooking.
If you love a spicier kick, add a splash of chili sauce or red pepper flakes into the sauce mixture.

Baked Sweet and Sour Chicken is sure to become a staple in your home. Its seamless blend of flavors, ease of preparation, and the joy of sharing a meal with family make it a go-to recipe. Feel free to experiment with ingredients, like adding different vegetables or adjusting sweetness levels to suit your taste.

Recipe FAQs

Can I use frozen chicken for this recipe?

Yes! You can use frozen chicken breast, but be sure to thaw it completely before cutting and coating it with cornstarch. This will help create a nice sear. If time is short, using pre-cooked chicken can also speed up the process, but adjust your cooking time accordingly.

What should I serve with Baked Sweet and Sour Chicken?

This dish pairs wonderfully with fluffy white rice, brown rice, or even noodles. You can also serve it alongside steamed vegetables for extra nutrition and color on your plate.

How can I fix a runny sauce?

If the sauce ends up too runny, you can thicken it by making a slurry with 1 tsp cornstarch mixed with 1 tbsp of cold water. Stir this mixture into the sauce while simmering on the stovetop until it reaches your desired consistency.

Can I make this dish ahead of time?

Absolutely! You can prepare the chicken and sauce beforehand. Just combine everything in your baking dish, cover, and refrigerate. When you are ready to eat, just pop it into the oven for a quick baking session. It’s a perfect make-ahead recipe for busy weeknights!
