Preheat your oven to 400℉.
Pat the chicken dry with paper towels. Season both sides with salt, pepper, and smoked paprika.
Heat olive oil in a large oven-safe skillet over medium-high heat. Add chicken and cook 2-3 minutes per side, until lightly brown.
In a small bowl, whish together the maple syrup, Dijon mustard, soy sauce, minced garlic, apple cider vinegar, dried thyme and red pepper flakes if using.
Pour the maple Dijon mixture over the chicken turning them to coat both sides.
Transfer the skillet to the preheated oven and bake for 25-30 minutes, depending on the thickness of the chicken. Check the thickest part with meat thermometer till reaches 165℉.
Remove the skillet from the oven and spoon the warm maple Dijon sauce over the chicken. Let the chicken rest for 5 minutes before serving.
Serve over rice and enjoy!
