Step 1 Preheat oven to 200°C. Spray a non-stick pan with oil. Heat over a medium heat. Gently cook onions and garlic until softened and slightly brown.

Step 2 Spray a large baking dish with oil. Place potato slices in a layer in the bottom of the dish, slightly overlapping at the edges. Place a third of the onion mixture over the top, then repeat with layers of potato and onion, until everything is used up. Pour milk over.

Step 3 Place in oven and cook for 25 minutes, covered in foil. Remove from oven and sprinkle over parmesan and thyme. Return to oven, uncovered, for 10 more minutes, or until cheese is melted and crispy.

What we did

• Removed the cream and cheese: Scalloped potatoes or potatoes daphinoise is often made with cream and cheese layers. This isn't necessary to get the cheesy flavour because when the milk cooks in this dish, curds separate and become cheesy and tasty.
• Left the potato skin on: This boosts the nutrients and fibre.
• Added onion, garlic and thyme: These add lots of tasty flavour without adding fat.
• Used a strong cheese: parmesan is a highly flavoured cheese which means you don't need to use very much to get lots of great taste.
