Pat dry and season: Blot chicken thighs dry with paper towels. Season both sides with salt and pepper.
Dry chicken browns better and gets that nice sear.
Whisk the sauce: In a small bowl, combine soy sauce, honey, rice vinegar, sesame oil, and red pepper flakes. Stir until smooth.
Heat the pan: Warm a large skillet over medium-high heat. Add oil and swirl to coat.
Sear the chicken: Add thighs in a single layer.
Cook 4–5 minutes per side until golden and nearly cooked through. Remove to a plate and tent with foil.
Sauté the garlic: Lower heat to medium. Add minced garlic to the pan and cook 30 seconds, stirring, until fragrant.
Don’t let it burn.
Deglaze and simmer: Pour in the honey-soy mixture. Scrape up browned bits from the pan. Simmer 1–2 minutes.
Thicken the sauce: Stir together cornstarch and water.
Pour into the skillet and stir. Simmer 30–60 seconds until glossy and slightly thick.
Finish the chicken: Return thighs and any juices to the pan. Spoon sauce over the top and simmer 2–3 minutes until cooked through (internal temp 165°F).
Garnish and serve: Top with sliced green onions and sesame seeds.
Serve with steamed rice, quinoa, or cauliflower rice and a side of veggies.
