Mix the sliced courgettes with the spices and the olive oil.
Preheat the oven at 180°C.
Arrange the slices of courgettes on a baking tray lined with parchment paper, sprinkle with 1/3 of the total amount of grated cheese. Bake for 20-30 minutes.
When the courgettes are almost ready, add the remaining part of cheese. Turn the chips a couple of times to ensure they will be crispy. They are ready when they are golden brown and crispy. It may be useful to bake them with the door of the oven slightly open for a few minutes toward the end.
