Sweet potato and blue cheese gratin

Step 1

Preheat oven to 350° F.

Step 2

Slice potatoes very thinly, about 2-3 mm

Step 3

Bring the cream and milk to a boil, add the scallions, garlic, spices, and cheeses, and stir for a couple of minutes until blended and the cheese has melted.

Step 4

Butter a dish, and arrange the potato slices in a circular pattern, alternating orange and purple slices, and slightly overlapping them.

Step 5

Pour some of the cream mixture on top.

Step 6

Continue to add a layer of potatoes, and cream, until you've used all potatoes. Finish with the last bit of the cream.

Step 7

Cover with foil and bake for 40 minutes. Uncover and bake for another 10-15 minutes or until the potatoes are very soft.

Step 8

Optionally sprinkle with more parmesan on top and return to the oven to create a cheesy crust.

Step 9

Add some fresh scallions on top and serve.
