Chop the potatoes into chunks about 2- 3cm squares (or leave whole if they are tiny!).
Separate all the cloves of garlic from the bulb but keep them in their little papery wrappers.
Toss everything on the ingredients list into a large roasting tray. You can add other herbs or more chilli as you wish.
Roast on a medium heat (200°C / 400°F / Gas Mark 6) for around 20 minutes. Then give it a stir around & check how it's cooking.
Roast for another 10 minutes or so (depending on your oven you might want to turn it up a bit to make sure you get those nice crunchy caramelised bits).
Sprinkle some herbs such as chopped parsley over if you like!
Serve warm, with some sauces and maybe a salad. Also brilliant as a leftover for lunch (so do make extra!).
