Preheat the oven to 400°F (200°C).
Pat the chicken thighs dry with paper towels.
Place the chicken thighs in a baking dish.
In a bowl, whisk together the honey, Dijon mustard, whole grain mustard, olive oil, garlic, paprika, salt, pepper, and thyme.
Pour the honey mustard mixture over the chicken thighs.
Turn the chicken to coat evenly.
Arrange the chicken skin-side up in the baking dish.
Bake for 40 to 45 minutes.
Baste the chicken with the pan juices halfway through cooking.
Continue baking until the skin is golden brown and the internal temperature reaches 165°F (74°C).
Allow the chicken to rest for 5 minutes before serving.
Spoon extra sauce from the pan over the chicken before serving.
