Depending on the potato variety you chose, you have two options : either peeling them or washing them very well without peeling. I usually prefer keeping their skin on !
Cut your potatoes into wedges and add them into a bowl big enough for all the quantity.
Sprinkle your olive oil, dried herbs & spices, salt and pepper on the potatoes. Mix well with your hands to make sure each potato wedge is covered.
Layer your baking pan with the baking sheet, then add all of your wedges making sure they're facing up (skin on the baking sheet). Add some fresh rosemary over your wedges.
Place your wedges in the oven along with the chicken. The great part is that the chicken & potatoes will be done at the same time !
