Chicken Thighs take around 30 to 35 minutes to bake in the oven at 375 F.
To bake chicken thighs in the oven preheat the oven to 375 F and place the chicken thighs into a baking dish and let the chicken thighs cook for 30 minutes then check the chicken thighs to see if there is any pink color to them.
If the chicken thighs have any pink color to the insides you need to cook them another 5 to 10 minutes until you see no more pink color and the juices should run clear.
You can also add flavor to the chicken thighs by seasoning the chicken thighs on all sides with garlic powder and onion flakes which makes for some very tasty chicken.
