Tarte tatin is usually made with fruit and is considered a delicacy. But Jamie Oliver came up with a recipe for savory onion tart tatin. Having tried his recipe, I decided to add champignons to this wonderful dish. It turned out perfect for cold winter days - hearty, tasty and healthy (onions are good for preventing seasonal colds and as a source of vitamins).
Defrost the prepared puff pastry. Coarsely chop the onion, lightly fry in olive oil, drizzle with balsamic vinegar, salt.
Add coarsely chopped champignons, simmer covered until tender (about 15 minutes).
Pour into a fireproof dish greased with olive oil and sprinkled with thyme. Cover with a layer of puff pastry, pierce it with a fork in several places. Lubricate the dough with yolk. Bake at 200 degrees for 25 minutes.
Invert onto a platter and serve topped with cream cheese. Delicious both hot and cold.
