To create the incredible Easy Baked Sweet and Sour Chicken, follow these straightforward steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Prepare a baking dish by lightly greasing it with cooking spray.
2. Prepare Chicken: In a large bowl, season the chicken pieces with salt and pepper. Make sure they are well-coated.
3. Make the Sauce: In a separate bowl, whisk together the ketchup, apple cider vinegar, brown sugar, soy sauce, cornstarch, garlic powder, and ginger powder until smooth.
4. Add Vegetables: Mix in the chopped bell peppers, onions, pineapple chunks, and broccoli florets to the sauce mixture.
5. Combine: Place the seasoned chicken pieces in the greased baking dish. Pour the sauce and vegetable mixture evenly over the chicken.
6. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
7. Uncover and Stir: After 30 minutes, remove the foil, stir well to ensure even cooking, and continue baking for an additional 15 minutes uncovered.
8. Check Doneness: After 15 minutes, check that the chicken is cooked through and the sauce has thickened. It should be bubbling and somewhat sticky.
9. Serve: Remove from the oven and let it cool slightly. Serve over cooked rice to soak up the flavorful sauce.
