Instructions
- Preheat the oven: Preheat your oven to 180°C (fan 160°C) / Gas Mark 4.
- Prepare the potatoes: Thinly slice the potatoes using a sharp knife or mandoline for even slices.
- Cook the onion and garlic: Heat a frying pan with low-calorie cooking spray. Sauté the onion and garlic on medium heat for 3-4 minutes until softened but not browned.
- Create the sauce: In a bowl, mix the skimmed milk and vegetable stock together. Add the thyme, nutmeg, salt, and black pepper.

- Add cheese: Remove the foil, sprinkle the grated reduced-fat cheddar over the top, and return to the oven for 10 minutes or until the cheese is golden and bubbling.
