With Parmesan and Tomato <3 Edit
Cover chicken thigh in olive oil, salt and pepper
Bake at 425; 400 fan for about 25 minutes
Check internal temperature is at around 160 degrees F
Add parmesan and sliced tomatoes (maybe grill them first, that'd be freaking delicious) to the baking pan and put back in oven for 5-6 minutes.
After 5-6 minutes, turn off the heat, and let the chicken stay in the oven.
Check internal temperature is around 170 degrees F before eating.
Enjoy. It's freaking delicious.
