Conveniently arrange all the ingredients. Wash and pat the meat dry with a napkin. Wash the mushrooms and clean them. If you use frozen champignons, defrost them in advance to drain the liquid. Peel the onion. Take out the meat hammer.
Prepare the meat. Cut it into bits. Beat them off with a kitchen hammer. Add salt, pepper and dry garlic to taste.
Prepare the roast. Cut the onion into cubes and sauté in vegetable oil in a frying pan until soft. Chop the mushrooms and add them to the pan. Stir and fry. Add salt and pepper to taste.
Prepare the chops for baking. Preheat the oven to 180 degrees. Line a baking tray with baking paper. Place the meat on a baking sheet. Place fried onions and mushrooms on top. Sprinkle with a little sour cream. Make an even layer of grated cheese. Drizzle with remaining sour cream. Bake the dish for 20 minutes.
Chops with mushrooms go well with mashed potatoes. Boil the potatoes for 15-20 minutes, mash, season with butter. Serve with hot chops.
