Place a medium saute pan over medium heat. Add butter and once it melts, add sage, rosemary and thyme then cook for about 5-7 minutes, stirring continuously, until the butter has browned then remove from heat.
Pour butter herb mixture over the potatoes, using a brush to get in the crevices of all the potatoes. Place extra thyme on top of potatoes and sprinkle with a couple hefty pinches of salt.
Place in oven to cook for 1 hour and 15-30 minutes. Check out 1 hour and 15 minutes to see if the potatoes are completely cooked through.
