Pat the chicken thighs dry and season both sides with salt and pepper.
Heat olive oil in a large oven-safe skillet over medium-high heat. Add the chicken thighs and cook for 4-5 minutes per side until golden brown.
While the chicken is browning, whisk together the cranberry sauce, orange marmalade, soy sauce, apple cider vinegar, Dijon mustard, and grated ginger in a small bowl until smooth.
Pour the glaze evenly over the browned chicken in the skillet.
Transfer the skillet to a preheated 375°F (190°C) oven. Bake for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F and the glaze is thick and bubbly.
Remove from the oven and let the chicken rest for 3-5 minutes. Spoon the extra glaze from the pan over the top of the chicken before serving.
Notes
Chicken thighs stay more moist than breasts, but breasts can be used with reduced cooking time (20-25 minutes).
Pat chicken completely dry before seasoning for the best browning and crispy exterior.
The glaze thickens as it cools and flavors intensify, making leftovers even more delicious.
Can be made ahead: brown chicken and prepare glaze up to 24 hours in advance, then bake when ready.
