Creating Sheet Pan Korean Popcorn Chicken is straightforward. Follow these steps for a flavorful result:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper for easy cleanup.

2. Prepare Chicken: In a bowl, combine the chicken pieces with cornstarch, salt, and pepper. Toss until the chicken is well coated.

3. Make the Sauce: In a separate bowl, whisk together the vegetable oil, gochujang, honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger until smooth.

4. Combine: Pour the sauce over the coated chicken, ensuring every piece is evenly coated.

5. Spread on Sheet Pan: Arrange the chicken in a single layer on the prepared baking sheet. Make sure there is space between each piece for even cooking.

6. Bake: Place the sheet pan in the preheated oven and bake for 25-30 minutes. Flip the chicken halfway through for even crispiness.

7. Garnish and Serve: Once golden brown and crispy, remove from the oven. Sprinkle with sesame seeds and chopped green onions before serving.
