Preheat your oven: to 180°C / 350-375°F / Gas Mark 4-5
Potatoes: use a knife and chopping board to dice your potatoes into small pieces.
Garlic: peel the garlic, remove the skin and cut the hard end off each clove.
Skillet: spray a 26cm or 10 inch oven safe skillet (or baking dish) with cooking oil.
Garlic cream sauce: add the cream, garlic, dried onion, rosemary, thyme, salt, pepper and half of the parmesan cheese to a medium sized bowl and whisk to combine.
Diced potatoes: transfer the diced potatoes into your skillet or baking dish.
Combine and bake: pour the garlic cream sauce into the skillet and ensure all potato pieces are pushed under the liquid. Place a layer of aluminium foil over the top of the skillet (optional). Oven bake for 50 minutes. Then use oven mitts to remove and place on a heatproof surface. Note 6
Cheese topping: sprinkle the grated cheese on top of the cooked potatoes. Use the oven mitts to return the skillet to the oven and bake for a further 5-10 minutes to allow the cheese to melt.
Rest: once the cheese has melted, remove the skillet from the oven using oven mitts, place it onto a heatproof surface and allow it to cool for 3- 5 mins as the sauce thickens (naturally).
To serve: garnish the potatoes with freshly chopped parsley and serve hot.
