Wrap the fillet in heatproof clingfilm or aluminium (see Top recipe tip) and roast in the oven for 30 minutes.
Use a meat thermometer to check the core temperature of the beef, it should be 57-59C /135-138F for medium-rare.
Remove the beef from the oven and heat a frying pan until hot.

To serve, spoon the mushrooms onto serving plates. Carve the beef into thick slices and place onto the plates. Spoon the mash alongside then finish with a drizzle of madeira jus.
Heatproof clingfilm is available from larger supermarkets but do check the packaging before buying. Using foil is a safer option but many chefs prefer cling film.
