Roast Beef with Onion Gravy and Mustard Yorkies

Roast Beef with Mustard Yorkies

Did you know it's National Yorkshire Pudding Day on Sunday? No?... neither did I until a few days ago! I don't think there's anything better on a lazy Sunday afternoon than tucking into a lovely piece of Welsh Beef, yorkies and all the trimmings. I always cook double the quantity so we can have leftover roast on a Monday. The kids have swimming lessons at different times this term which means eating at different times too. I don't like it but there's no way my 10 month old and 6 year old could wait for their big sister, so it's ding cuisine all the way!

This recipe notches up the flavours a bit with a lovely caramelised onion gravy for the Welsh Beef and a good dollop of wholegrain mustard in the yorkshire pudding batter. These few little tweaks make a huge difference to the end taste. I hope you'll celebrate National Yorkshire Pudding Day with me this year by making a yummy roast beef dinner.

Roast Beef with Onion Gravy and Mustard Yorkies

Welsh Roast Beef with Mustard Yorkshire Puddings for National Yorkshire Pudding Day.
prep time: 15 minscook time: 1 hour and 45 minstotal time: 1 hours and 60 mins


  • For the Beef:
  • 1 TBSP Black peppercorns
  • 1 TBSP English Mustard Powder
  • 1 TBSP Dried Thyme
  • 1 TBSP Olive Oil
  • 2kg topside joint of Welsh Beef
  • For the Onion Gravy:
  • 4 TBSP Plain Flour
  • 2 Beef Stock Pots ( I use Knorr)
  • 3 TBSP Caramelised Onion Chutney
  • 2 TSP Marmite
  • For the Mustard Yorkies:
  • 175ml Full Fat Milk
  • 2 Large Eggs and 1 Egg White
  • 1 TBSP Wholegrain Mustard
  • 115g Plain Flour
  • Goose fat from a can


  • Step 1:  Crush the peppercorns, mustard powder and thyme together with some salt, using a pestle and mortar. Stir in the oil, then rub it all over the beef.
  • Step 2: Heat oven to 190C/170C fan/gas 5 and sit the joint in a roasting tin. Roast for 15 mins per 450g/1lb (about 1 hr 10 mins) for medium-well.
  • Step 3: Remove from the oven, lift onto a platter, cover with foil and rest for 30 mins. If you’re making the Yorkies increase oven to 220C/200C fan.
  • Step 4: For the gravy, pour any juices from the roasting tin into a jug. Let the juices separate, then spoon 2 tbsp of the fat back into the tin. Sit the roasting tin on the hob and stir in the flour, stock pots, onion chutney or marmalade and Marmite. Cook for 1 min, stirring well to scrape up any beefy bits stuck to the tin, then gradually stir in 750ml hot water from the kettle. Bubble to thicken to a nice consistency, then gently keep warm until ready to serve with the beef, carved into slices.
  • Step 4: For the Yorkies, make the milk up to 225ml/8fl oz with water. Beat the eggs, egg white, mustard and milk together, then gradually add the flour and ¼ tsp salt. Pour into a jug.
  • Step 5: Put 1 tbsp goose fat or oil in each of 8 large Yorkshire pudding tins and heat for 15 mins in the oven. Pour the batter into the tins, then cook for 15-20 mins, without opening the oven.
