Peel the beetroot. Rince it under cold water to make sure you remove all the dirt. Using a mandolin slicer (technically, you can also use a knife but it will be tricky), finely slice it about 1mm thick.
Put the baking sheet in the oven and let it cook for 50 to 60 minutes or until the beetroot slices get crispy. And voilà!Bon appétit !
