Clean the mushrooms and, depending on their size, halve or leave them whole. Wash and quarter the tomatoes. Peel and chop the onion. Cut turkey breast into large cubes. Heat 1-2 tablespoons of oil in a large pan.
Brown the meat all around in it and take it out. Add 1 tablespoon of oil. Add mushrooms and onions to the hot frying fat and fry while turning. Add meat and tomatoes, season with salt and pepper and dust with flour.
Sweat briefly and deglaze with broth and tomato juice. Bring to the boil, cover and stew for about 5 minutes. Meanwhile wash parsley, dab dry and cut into fine strips, except for a little garnish.
Season the finished turkey ragout with salt and pepper. Put crème fraiche on the ragout and let it melt. Arrange the ragout in small bowls and serve sprinkled with parsley and garnished.
Serve with baguette.
