An apparatus for preparing hot beverages, in particular soups, includes a frame (1) containing a heating system (2) for heating water drawn from a water main or, alternatively, from a tank, and for converting the water into pressurized steam. The steam is delivered to a heating chamber (3) having a discharge duct (4) that passes through the heating chamber. A beverage to be prepared is stored in an aseptic pack (61) placed in a removable receptacle (7) housed in the frame (1). The liquid beverage is delivered from the aseptic pack (61) to the discharge duct (4) by a sequential dispenser (6), and is then discharged to a container (5).
