4 tbsp (60 g) melted butter, divi
3 lbs (1.5 kg) small Yukon Gold potatoes or yellow potatoes
2 garlic cloves, finely sliced
1½ cups (375 ml) whipping cream
1 rosemary sprig, leaves removed and finely chopped
3 thyme sprigs, leaves removed and finely chopped
salt and freshly ground pepper
- Preheat oven to 350 F (180 C).
- Using 1 tbsp (15 ml) of butter, brush a medium sized gratin dish. Using a mandolin or a sharp knife, slice potatoes very thinly, about ⅛-in (0.25 cm). As they are sliced, stack potatoes in piles and pack them into the dish standing upright, spreading them apart slightly, starting from outside, building a trail around the dish and then spiraling towards the middle. Divide the garlic and slip garlic slices in between some of the potatoes.
- Drizzle cream and remaining melted butter over potatoes, then sprinkle rosemary and thyme over top. Season well with salt and pepper.
- Bake for 1 hour or until potatoes are tender and cooked through. Increase heat to 400 F (200 C) and bake for another 10 to 15 minutes to crisp top.
