Season the beef roast with salt and pepper on all sides.
Heat the roasting pan over medium-high heat and brown the beef on all sides along with the bacon, turning the meat several times, for about 8-10 minutes.
Deglaze the pan alternately with wine and brandy, allowing 1-2 minutes of simmering between each addition; repeat this process several times.
Cover the roasting pan and transfer to a preheated oven at 160°C (320°F); braise for 1 hour 45 minutes.
Add the mushrooms with their liquid 30 minutes before the end of braising time (at 1 hour 15 minutes).
Remove the beef from the roasting pan and place on a cutting board to rest.
Place the roasting pan with its sauce on the stovetop over medium heat; pour in the cream and stir to combine; season with salt and pepper.
If desired, simmer the sauce for a few minutes to reduce and concentrate the flavor.
