Wash your apples.I use one apple per person, and slice about 4-5 medium size apples per batch as this is what fits onto a standard baking tray
Slice the apples.You can use a mandolin but I simply slice the apples as thinly as I can using a really sharp knife
Lay your apple slices on the baking tray. You can use a teeny bit of Olive oil, but I prefer to use a good non-stick baking tray like this one. Your apples won’t stick much to the pan, so if you do need to use an oil, use it sparingly
Layer the apple slices in your tray no more than 2-3 slices deep
Stick your tray in the oven. Your oven needs to be on very very low. The natural sugars in apples mean it’s easy to burn your apples if the heat’s to high. Your oven should be warm, rather than hot
Cook for 1.5 hours. Turn your apples gently (they can be delicate before they’re fully dried out) every half hour
15 minutes before they come out. Drizzle a table spoon of maple syrup over the apples. This gives them a lovely shine and the maple syrup cooks right into the apple slice
Take out of the oven. Your apples will harden as they cool
Serve! In our house our kids like to have their own tiny pot of Maple syrup on the side for dipping!
Notes
For cinnamon lovers, sprinkle cinnamon on your chips before they go in the over. The moisture form the apples will mix with the cinnamon and cook into your apple
