In a pan, sauté an onion, once tender, add mushrooms, season with salt and pepper, and sauté. Once the liquid has evaporated, add 15 ml of cooking cream. Brown the sirloin in a pan. Let the sauce and the sirloin cool. Next, prepare the phyllo dough, roll it out, and spread the sauce you previously made with a little foie gras and thyme on the dough. Spread mustard on the cooled sirloin. Wrap it with the phyllo dough. Now, place the sirloin on a layer of puff pastry and seal it well on the sides. Brush with beaten egg and bake in the oven for 40 minutes at 200 degrees Celsius. Let it rest for 15 minutes before serving.
