Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 325°F (165°C).

Add the vegetable oil to a 9×13 baking dish and place it in the oven while preheating. This warms the oil and helps create a crisp coating.

Tip: A hot pan helps replicate the effect of frying.

Step 2: Prepare the Chicken Coating

Season the chicken pieces with:

Salt
Pepper
Garlic powder

Set up two bowls:

Bowl 1: beaten eggs
Bowl 2: mix cornstarch and flour

Dip each chicken piece into the egg mixture, then coat in the flour mixture.

Pro Tip: Shake off excess flour for an even crispy coating.

Step 3: Brown the Chicken

Heat a skillet over medium-high heat and lightly brown the coated chicken pieces in a little oil.

You don’t need to cook them fully—just 2 minutes per side until golden.

Why this works: Pre-browning creates a crisp texture that holds up during baking.

Step 4: Bake the Chicken

Carefully remove the hot baking dish from the oven.

Add the chicken pieces in a single layer.

Bake for 20 minutes, then flip the chicken pieces and bake another 15–20 minutes.

This process ensures even crispiness on all sides.

Step 5: Prepare the Sweet and Sour Sauce

In a medium bowl whisk together:

Sugar
Ketchup
Rice vinegar
Soy sauce
Garlic powder

In a separate small bowl mix:

Cornstarch
Water

Add the slurry to the sauce mixture to help it thicken during baking.

Step 6: Coat and Finish Baking

Pour the sweet and sour sauce evenly over the baked chicken.

Return the dish to the oven and bake for 10 more minutes, stirring halfway through.

The sauce will thicken and coat every piece beautifully.

Step 7: Garnish and Serve

Remove the chicken from the oven and garnish with:

Green onions
Sesame seeds
Fresh pineapple chunks

Serve hot over steamed rice, fried rice, or noodles.

Too much cornstarch can make the sauce overly thick or gummy.

Baking at Too High a Temperature

Moderate heat ensures the chicken cooks evenly without burning.
