Gratins have been around since the invention of the stove I reckon. If you think about it, a lasagne, cauliflower and cheese and a haché parmentier are roughly the same thing: some carbohydrates or vegetables mixed in with a béchamel and potentially some cheese, stuck into an oven until it all turns into a beautiful melting pot of a dish, covered with a bubbling crust.
A good gratin is a staple dish in our house, as it gives new life to leftover pasta, potatoes or vegetables. I mostly use either single cream for my bakes or a tomato sauce to bind the main body of the dish together and then top it with grated cheese. I then stick it in the oven, which has been preheated to 180° and bake it for 30-40 minutes until it is golden brown on top and bubbling.
I don’t think I have ever eaten a bad gratin and, eaten with a crispy green salad, it is a really lovely meal.
Above is a gratin I made the other day with broccoli, potato and some lardons!
