Preheat the oven to 200 C/400 F.: When you step into the kitchen, you should already smell faint warmth from the oven as it comes up to temperature, and having the oven ready ensures the chicken finishes evenly. This temperature helps the exterior crisp while the inside finishes cooking without drying out. A common mistake is to skip preheating, which can lead to uneven cooking because the oven will take time to reach the proper heat.
Season the chicken with salt and pepper and mix well.: Right after seasoning, inhale the faintly savory scent of the spices working into the meat, and you will notice the surface becoming a touch tacky, which helps coatings adhere later. Seasoning early builds deeper flavor rather than just a surface hit at the end. Don’t over season, which can make the pieces taste too salty after the soy sauce in the glaze is added.
Beat eggs well. Dredge chicken in eggs and then in cornstarch and coat well.: When the eggs are beaten thoroughly, they form a smooth, glossy bath that the cornstarch can cling to, producing an even pale coating. Run your fingers through a piece to check coverage; it should feel evenly dusted and not patchy. If you hurry this step, the coating can be uneven and will fry inconsistently.
Heat the oil in a skillet and add chicken. Cook until golden from all sides.: As pieces hit the hot oil , listen for a lively sizzle and watch for even golden spots forming across surfaces. That audible sear and the developing color indicate the crust is setting and flavors are concentrating. If the oil is not hot enough, the coating will absorb oil and become greasy rather than crispy.
Combine the buffalo sauce, brown sugar, soy sauce, olive oil, garlic, pepper, rice vinegar, and paprika in a bowl.: Whisking these ingredients releases a sharp tang and an underlying sweet aroma that promises the final glaze, and the sugar will begin to dissolve as the mixture warms slightly. This melded sauce should smell balanced, neither purely sweet nor overly sharp. A common misstep is adding cold sugar that does not dissolve, leaving grainy texture in the sauce.
Add chicken, and mix well. Pour coated chicken into an oven-safe dish. Cover with aluminum foil and bake in the oven for 20 minutes.: After tossing the warm chicken in the sauce, you will see a glossy coat begin to cling and steam rise as flavors marry. Covering with foil traps heat and helps the sauce penetrate while keeping moisture inside so the chicken stays tender. Avoid leaving the dish uncovered for the whole bake, which can dry the meat before the sauce has fully set.
Remove the foil, stir the chicken, and bake for another 10 minutes until lightly browned on the edges.: When you take off the foil, the aroma becomes more concentrated and you’ll hear the edges begin to sing in the oven as they crisp. Stirring helps redistribute sauce so edges caramelize evenly and you can visually confirm small browned spots forming. Watch closely, because leaving it too long can burn the sugar in the glaze and create a bitter finish.
