Potato Gratin with Chicken

15 minute potato gratin with chicken and bacon greens: a gratin always seems more effort and more indulgent than ordinary boiled or roasts, but it doesn't have to take 45mins, it's nice for a change and you can control the calorie content by going with full fat to low fat creme fraiche. (It's always tastes better full fat though obviously!) to serve 4: use 800g of potatoes, finely slice and boil in a pan for about 5-8 mins till firmish, not soft. Finely slice 3 onions and place in an oven dish with 2 tblsp of olive oil and 100ml of chicken stock. Cook till the onions are soft then drain the potatoes and pour onto the onions. Season and spoon over cream or creme fraiche till all is covered but not swimming. Grate Parmesan over the top then finish under the grill till nicely golden. serve with chicken and bacon, peas and spinach.

Cooking notes

When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
