Home made potato chips

I have some duck fat in a jar that is close to expiring...I think it is about 8 oz. I am having a couple friends over for a bbq in a couple weeks and thought I would make home made potato chips fried in duck fat as an cocktail munchie. since it isn't a lot, I can't really deep fry. Can I shallow fry them and should they be fried twice like French fries are? I have also run across a recipe that lays them on a sheet pan and brushes them on both sides with the duck fat and bakes them. This would obviously be way easier & I wouldn't be standing there frying when my guests arrive but I wonder if they will really crisp up like they should in the oven.
I plan to sprinkle with a little maldon salt & a tiny bit of garlic mixed with parsley when I take them out.
Has anyone done this? Suggestions?
