Preheat the oven to 400 degrees F. Lightly grease a large sheet pan, set aside.
Rub coconut sugar over the chicken thighs. In a small bowl, mix together the ranch seasoning and oil. Rub about 2 tbsp of the ranch "paste" over the chicken, and place on the baking sheet. The remaining ranch will be used for the potatoes.
Dice up the potatoes into halves or quarters and place in a large bowl. Spoon the remaining ranch paste on the potatoes and toss to combine until well coated. Pour the potatoes on the baking sheet with the chicken.
Dice up the bacon and spread all over the chicken and potatoes. Transfer the pan to the oven.
Bake for 20 minutes, then bump up the temperature to a broil. After 2-3 minutes, place the cheese slices on top of the chicken. Return the pan to the oven for another 1-2 minutes. Remove from oven and serve hot.
Garnish with optional fresh herbs and season with salt and pepper if needed.
