I offer a recipe for a French cake. The French are very fond of dishes with onions. Soups, cupcakes and pies are also made from it, so we bought red onions and decided to bake them today. Puff pastry without yeast.
Chop the onion, defrost the mushrooms, measure the sour cream, break the eggs into a separate bowl with melted butter.
Mix cream, sour cream, flour and eggs, add melted butter.
Preheat the butter.
Fry the mushrooms and onions in a frying pan heated with butter.
Mix the sour cream mixture with fried onions and mushrooms, season with salt and pepper.
Roll out the dough, cover the baking sheet with parchment paper. Put the dough on a baking sheet, make the sides and pierce with a fork.
Put the filling of onions, mushrooms and a mixture of sour cream, cream and flour on the dough. Preheat the oven to 180 * and put the prepared pie on for 50 minutes.
