Cut the beef into 4-5 cm cubes. Cut the bacon into 2-3 cm cubes. Halve the shallots, roughly dice the garlic and leave the mushrooms whole, peel if necessary.
Sear the beef in clarified butter, lower the temperature and add the bacon, leave out a little for 5 minutes, then add the shallots and garlic, and fry for another 5-10 minutes at low temperature. Pepper properly!
Cover with red wine, put a lid on and stew on the lowest heat for about 1 hour. Open and add the mushrooms. If necessary, add red wine. Cover again and simmer again for about 1 hour until the meat can be practically cut with a fork.
Season to taste with salt (careful, some of the bacon will come out) and pepper, and serve with plenty of baguette to dip.
