Arrange a rack in the middle of the oven and heat to 375°F.
Wash the sweet potatoes and cut off a small sliver on the bottom of the potato to give it a stable surface. Cut the sweet potato into rough ¼-inch slices, leaving ⅛ inch intact at the bottom.
Place salt, herbs and lemon zest in a bowl. Massage salt with herbs until flavors meld. Mix in pepper.
Carefully rub potatoes with olive and make sure some gets into the slices. Place salt mixture in a baking dish and roll potatoes until they are completely covered. Baked 45-60 minutes.
