Peel and slice the potatoes to be cooked as french fries.
Add sliced potatoes into a bowl, together with salt and spices.
Slice butter into small pieces and add over the bowl with potatoes.
Use your hands to mix the potatoes with butter and spices until well combined.
In a regular baking tray, lay down a sheet of parchment paper. Arrange potatoes side by side, forming rows and columns.
Transfer in the oven and bake for 40-45 minutes at 180 Celsius. Test from time to time to make sure they won’t burn.
Remove from the oven when done and set aside for a few minutes to cool down before serving. Enjoy and share!
