Preheat your oven to 450 degrees F. This high temperature is crucial for achieving that crispy exterior. While the oven heats up, you can prepare your baking sheets. Line two rimmed baking sheets with foil for easy cleanup, and spray them with non-stick cooking spray to prevent sticking.
In a mixing bowl, combine flour, cornstarch, and salt. Whisk them together until well combined. This mixture will give your chicken that desired crunch. Using paper towels, dry each drumstick thoroughly.
Once dried, roll each drumstick in the flour mixture, ensuring an even coating. It’s important not to overload them; a light dusting is all you need.
Lay the coated drumsticks out on the baking sheets, making sure they are evenly spaced. This will allow for even cooking and crisping.
Now, pop the baking sheets in the preheated oven and bake the drumsticks for 30 minutes. Be sure to flip them halfway through to ensure even cooking and browning.
While the chicken is baking, it’s time to prepare the sauce. In a medium sauce pot, pour in the pineapple juice along with the remaining ingredients: brown sugar, soy sauce, rice vinegar, ginger, garlic, and Sriracha. If you’re cautious about heat, stick with 1/4 cup of Sriracha; if you crave spice, go for 1/2 cup. Bring the mixture to a boil over medium heat.
Once boiling, reduce the heat and let the sauce simmer for 30 minutes. During this time, it will thicken up and develop beautiful flavors.
After 30 minutes, take the drumsticks out of the oven and pour the delicious sauce over them evenly. Use tongs to roll each drumstick around in the sauce to ensure they are well coated.
Put them back in the oven, uncovered, and bake for another 20 minutes. This final step allows the sauce to caramelize and gives your drumsticks that sticky, flavorful finish.
Once they are out of the oven, let them rest for a few minutes before serving warm. Enjoy the delightful flavors of your Baked Chicken Drumsticks!
