Steps
- 01
Heat the oven to 180°C. Melt the butter and combine it with the cream and minced garlic.
- 02
Peel potatoes and slice them about 3 mm thick; protect your fingers if using a mandoline.
- 03
In a 1.5–2 L baking dish, layer one-third of the potato, cream mixture, salt, pepper and thyme; add ¾ cup cheese. Repeat for the second layer.
- 04
Add the last third of potato and the remaining cream, seasonings and thyme. Reserve the final 1 cup of cheese.
- 05
Cover and bake for 75–90 minutes until a knife passes easily through the potatoes in the center.
- 06
Remove the cover, add the reserved 1 cup cheese and bake another 10–15 minutes until golden. Rest 5 minutes and divide into 10 portions.
