Preheat the oven to 180°C and line a baking tray with paper.
Place Parmesan into the Thermomix bowl and mill 10 sec/speed 10.
Add to a large mixing bowl and add all other ingredients. Give them a very good toss to coat the croutons well.
Spread across the prepared tray and bake 20-25 minutes stirring occasionally as needed.
When golden and fragrant, either use immediately or store in an airtight container in the fridge until use. They will keep well in the fridge for up to 3 weeks.
