Prep the Chicken: Pat the chicken thighs dry with paper towels to ensure a perfect sear. Cut into 1-inch pieces and season well with salt and pepper.
Make the Sauce: In a medium bowl, whisk together the honey, chicken stock, rice vinegar, soy sauce, and minced garlic. In a separate small dish, mix the cornstarch with a splash of water to create a slurry.
Sear the Chicken: Heat the vegetable oil in a large skillet over medium-high heat. Add the chicken and sear for 3–4 minutes per side until golden brown and cooked through. Remove and set aside.
Simmer the Sauce: Lower the heat to medium. Add the butter to the skillet. Once melted, pour in the sauce mixture and let it simmer for 1–2 minutes. Stir in your cornstarch slurry and cook until the sauce thickens into a glossy, sticky glaze
Toss and Garnish: Return the chicken to the skillet, tossing thoroughly to coat every piece in that delicious sauce. Garnish with fresh parsley and chili flakes. Serve hot over white rice.
