Cut the potatoes into chip shapes and put in a bowl. Drizzle with 2 tablespoons of olive oil and add a little salt and pepper. Mix together thoroughly so all the chips are evenly coated in the oil and seasoning.
Spread the chips out on the baking trays - you will probably need 2 or 3 to ensure the chips are well spread out and not touching.
Put the baking trays in the oven for 10 minutes.
After 10 minutes take one baking tray out of the oven and turn all the chips over. Put that tray back in the oven and repeat for the other trays.
Cook the chips for 10 more minutes, then repeat - turning each chip again.
Cook the chips for 10 more minutes (so they have had 30 minutes cooking in total) or until they are done – I find trying one is the best way of knowing if they are done! (Just don’t burn your mouth – they will be hot!!)
Serve with a nice steak, a homemade burger, a tuna steak or whatever you usually serve chips with.
