Step one: cook the courgettes

In a pan add the olive oil and the onion finely chopped, cook the onions until soft, then add the garlic and stir for a minute or so. Then add your grated courgettes, a bit of salt and pepper and stir, lid on, let them cook on a low heat for 10 to 15 minutes until they are soft.

Step two: make a bechamel sauce

In a pan melt your butter, once melted add the flour and stir constantly for a good minute or so. Off the heat, using a whisk, slowly add your milk and stir until all the milk is incorporated. Then put it back on the heat and stir constantly until your bechamel thickens. Off  the heat add your cheese and your cooked courgettes and stir. Separate the egg yolks, keep the whites. Add the yolks to the mixture and stir.

Step three: the final stage

Pre-heat your oven at 180° C

Whisk your egg whites into stiff peaks. Gently fold your whites into your bechamel, courgettes sauce, one spoonful at a time. It is very important to take time to do this correctly. Once all your whites are incorporated fill your ramekins to the top. Pop them in the oven for 15 to 20 minutes.
