This is a good quick supper, easy and tasty. I scored some cheap ham at the co-op this afternoon. Top tip – if you want to eat cheaply and feel good about stopping food waste, Sunday afternoons at the co-op is peak bargain time.
After we ate this, we reflected that we could have snuck in a layer or two of lasagne as well.
- 3-4 leeks
- approx 4 slices of cooked ham, chopped
- 40g butter
- 40g flour
- salt and pepper
- 150ml of cooking liquid from the leeks
- 300ml milk
- 1/2 tsp prepared mustard
- 100g grated cheese
- Prepare the leeks, cut them into 1 cm slices and cook in boiling water for around 7 minutes.
- Drain the leeks and reserve the cooking liquid.
- Put the leeks into the bottom of a gratin dish, and cover with a layer of ham.
- Fry the flour in the butter, for around a minute, and then add the liquid to make a smooth sauce, and simmer for a couple of minutes.
- Add half the cheese, along with the mustard and a grating of nutmeg, salt and pepper to taste. Cook until the cheese is all melted into the sauce
- Pour the sauce over the ham and leeks, then top with the rest of the cheese and then the breadcrumbs
- Cook for 10 minutes under a moderately hot grill, until the topping is nicely browned.
