Put the butter in the pan and put on the heat. Sauté the shallot and garlic until soft.
Add the shiitake cubes. Let it simmer for a few minutes.
Pour and spread the egg gels in the pan. It is best not to stir again unless the mixture is not evenly distributed. Cook for 1 minute. The egg mixture should not be set at the top.
Add some parsley.
Place the pan in the oven as high as possible. Keep a close eye on it because it can go "fast". Again, a minute is usually enough. Now we bake the above layer of the omelette.
By using the grill function of the oven, we bake the top faster and prevent you from having to put the pan on the fire for too long. Sometimes the result is a bottom that is too brown.
Place the omelette on a plate. Tasty!
