This roast beef almost cooks itself with the “beefy” potatoes in the gravy, it’s quite delicious, and lazy. Pretty much a staple of Sunday lunch in our household, and beef sandwiches the day after.

What should I serve with it?

Fresh greens such as peas or cabbage. And of course a Yorkshire puddings, it wouldn’t be a roast without Yorkshire puddings.

Storage tips

  • Cool the beef as quickly and safely as possible.
  • Slice the beef into smaller pieces.
  • Remove from the sauce or gravy
  • Take out of the slow cooker.


Slice the beef into smaller chunks before freezing,  this will mean it will take less time to freeze and defrost. It also has the pleasant side effect of you only have to defrost what you need.


Defrost the beef overnight in the refrigerator before you use it.


The beef can be reheated in the oven on a low temperature and wrap it in a little aluminium foil to avoid drying out.

  • Adding the beef to your slow-cooker then add the vegetables. The stock should come halfway up the beef joint. If not make a little extra beef stock.
  • Cover the slow-cooker and leave for 5 hours on low or 3 hours on high. (I cooked for 3 hours as I used half the meat as you can see in the photos it was a tiny joint of beef)
  • Once the beef is cooked remove from the slow cooker and cover with foil and rest for 15 minutes .
  • While the beef is resting, remove the vegetables from the slow cooker, and drain the fluids into a pan, straining through a sieve. Saving the gravy in a pan.
  • Discard the contents of the sieve and bring the gravy to a boil, adding the cornflour to thicken the gravy and season to taste.
