It’s not the most sophisticated dish, to be honest, but it works on so many levels. It helps to tidy up the loose ends from your fridge and takes minutes to assemble the dish, and goes so well on a midweek cold evening.
LEFTOVERS CHEESY GRATIN
1 onion, finely chopped
2 tablespoons Dijon mustard
200g mature cheddar, grated
3 cooked potatoes, sliced
200g frozen peas
200g any cooked meat/ham (optional)
salt & pepper to taste
- Heat the oven to 200C.
- Melt the butter in a saucepan, add the onion, cook until it’s soft and translucent. Then stir in the flour and cook for 1 minute. Gradually stir in the milk until smooth with no lumps, (I prefer to use a whisk for that) keep stirring until the mixture begins to bubble and thickens to a creamy sauce. At this stage add the mustard and cheese, leaving a handful of grated cheese aside for the topping. Check for seasoning and remove from the heat.
- Place potatoes, peas and cooked meat or any other cooked vegetables you’d like to use up, in a deep oven proof dish. Pour over the cheese sauce, then sprinkle with remaining cheddar.
- Bake for 20-25 minutes or until the topping is golden and crisp.
