Clean and sanitize the mushrooms. Peel and finely chop the onion. Wash and halve the tomatoes. Wash the meat and dab dry with kitchen paper. Put 30 g flour in a deep plate, mix with salt and pepper.
Turn the meat in it, lightly beat off the flour. Heat the oil in a large frying pan and fry the meat for about 2 minutes on each side. Remove from the pan and set aside. Add the mushrooms to the frying fat and fry well all around.
Add the onion and fry briefly. Add juniper, bay leaf and marjoram. Season with salt, pepper and paprika. Stir in tomato paste, dust with 20 g flour, sauté and gradually add stock and cream.
Bring to the boil and season again with salt and pepper. Add the tomatoes. Put the cutlets into an ovenproof dish, spread the chasseur sauce evenly over them and cover with bacon. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 1 hour.
Cover after approx. 30 minutes. Serve the casserole garnished with marjoram.
