Mums Gruyere Gratin

Method

• step 1

  Preheat the oven the 170C/fan 180C/non-fan

• step 2

  Peel the Sweet Potatoes, and cut as many thin slices to cover the bottom of a Shallow Casserole dish with 1 layer, cover the layer with 1/4 of the tub of double cream, then on top of the cream, cover with 1/4 of the Gruyere cheese.

• step 3

  Repeat this step another 3 times til you have 4 layers of thinly sliced sweet potatoes topped with cream and Gruyere cheese.

• step 4

  Place on the middle shelf of the oven for 45 mins. (low heat of above as the cheese on top caramelises)

• step 5

  No need for any seasoning, found that it can spoil the flavours. Tip- thinner the sweet potatoe, softer the dish.
