Coat chicken in 1/4 cup cornstarch, salt and pepper, tossing to combine.
1 pound boneless skinless chicken thighs, 1/4 cup cornstarch, 1/2 teaspoon fine sea salt, 1/4 teaspoons ground black pepper
Heat the oil in a skillet set over medium-high heat. Add the chicken and cook for 3-5 minutes per side or until the internal temperature reaches 165°F.
3 tablespoons neutral-flavored cooking oil
Transfer to paper towel lined plates and set aside to drain of excess oil.
In a small bowl, whisk together the gochujang, soy sauce, rice vinegar, toasted sesame oil, sugar, and garlic.
In a separate bowl, whisk together the remaining 1 1/2 teaspoons of cornstarch with 1 tablespoon of water until smooth.
1 1/2 teaspoons cornstarch
Heat the gochujang mixture in a small saucepan set over medium heat. Once simmering, whisk in cornstarch mixture. Whisk the sauce constantly until slightly thickened, 2-3 minutes. It will continue to thicken a bit as it cools down. If it winds up being thicker than you prefer, whisk in some additional water, 1 teaspoon at a time, until the desired consistency is reached.
Toss the chicken and the sauce together in a bowl. Optionally, you can toss the chicken with only 1/2 to 3/4 of the sauce, then drizzle the remaining sauce over the chicken when serving.
Plate the chicken with rice and peas, then garnish with chopped green onion and toasted sesame seeds.
