Preheat oven to 400 degrees
Step 1: Boil the potatoes. In a pot add potatoes, chicken stock and big pinch of salt. Heat on high and once it reaches a boil set the timer for 10 more minutes. Drain out the liquid but keeping potatoes in the pot.
Step 2: Bruise the potatoes. With the hot potatoes in the pot, shake them about a couple of shakes just to bruise them (you want the potatoes to still maintain their shape).
Step 3: Mix with oil, herbs and bake. On a baking sheet add potatoes, garlic, sage, lemon zest, 2 big pinches salt, drizzle olive oil (three times around the sheet pan) and butter. Mix ingredients together using your hands.
Step 4: Bake for 50 minutes (no need to stir or shake) and enjoy!
