Step 1: Prepare the Chicken - Pat the chicken thighs dry with paper towels. Season both sides with salt and pepper to taste.
Step 2: Sear the Chicken - In a large skillet, heat the olive oil over medium-high heat. Add the chicken thighs and sear for about 5-7 minutes per side or until golden brown and cooked through. Remove from skillet and set aside.
Step 3: Make the Glaze - In the same skillet, reduce heat to medium and add the brown sugar, soy sauce, hoisin sauce, sweet chili sauce, ginger, garlic, and lime juice. Stir to combine and bring to a simmer.
Step 4: Glaze the Chicken - Return chicken to the skillet, coating in the glaze. Cook for an additional 2-3 minutes, turning to coat evenly and allow the glaze to thicken.
Step 5: Serve and Enjoy - Remove from heat and serve over rice or with your favorite sides, sprinkling with red pepper flakes if desired.
