Prep the Chicken:
Pat chicken dry and season with salt and pepper. Toss with cornstarch if using (for a light crispy coating).
Sear the Chicken:
Heat oil in a large skillet over medium-high heat. Add chicken in a single layer and cook 3–4 minutes per side until browned and cooked through. Remove and set aside.
Make the Sauce:
In the same pan, reduce heat to medium. Add honey, soy sauce, rice vinegar, garlic, and red pepper flakes. Stir and bring to a simmer.
Thicken and Combine:
If you like a thicker glaze, mix water with cornstarch and stir into the sauce. Let simmer 1–2 minutes until thickened.
Return Chicken:
Add cooked chicken back to the skillet. Toss to coat in the sauce and cook 1–2 more minutes until glazed.
Serve:
Garnish with green onions and sesame seeds. Serve over rice, noodles, or steamed vegetables.
