Start by making the béchamel sauce, in a pan add the butter and melt it over a medium heat. Sprinkle in the flour and stir it well until it forms a sandy paste. Cook for a minute.
Pour in the milk, then use a whisk to beat it. Continue to cook until it thickens.
Turn off the heat, then add the parmesan and nutmeg and mix well. Season with salt and pepper. Set it aside.
Preheat the oven to 180C Fan, or the grill to a medium-high setting.
Pop the chicken breasts each into a sandwich bag, then use a rolling pin or a meat hammer to bash until it’s an even thickness. You want it to be about 5mm thick.
Pop the flour, eggs, and breadcrumbs each into separate bowls/trays. Coat the chicken in the flour first, then the beaten egg and finally the breadcrumbs.
Heat a good amount of cooking oil in a large frying pan, sprinkle in some breadcrumbs, and when they sizzle the oil is hot enough.
Shallow fry the breaded chicken until it’s golden and crisp on both sides. You might need to do one at a time depending on the size of your pan.
Remove the chicken from the pan, firstly onto kitchen paper to get rid of any excess oil, then onto an oven proof dish.
Spoon over some of the béchamel sauce, then top with some grated cheese.
Pop them either in the oven, or under the grill until the cheese has melted. Enjoy.
