Slice Sweet potatoes thinly (preferrably with a Mandolin on a thin setting). Coat a large sheet pan with olive oil. Laysweet potatoes on coated pan (do not layer the sweet potatoes onto eachother unless you don’t mind less crispy chips).
Sprinkle half of herb mixture on top of sweet potatoes. Bake 10 minutes at 375 degrees. Check chips and turn pan or chips for even baking if needed. Sprinkle the rest of herb mixture on top. Bake another 10 minutes or until crispy. Enjoy!
