Equipment

  • Large Saucepan
  • Microplane/Grater

Ingredients

Ragù

  • 800 g Leftover Roasted Prime Rib (See Notes)
  • 2 White Onions
  • 2 Large Carrots
  • 2 Celery Sticks
  • 4 Garlic Cloves
  • 2 tbsp Vegetable Oil
  • 1 tbsp Tomato Puree
  • 250 ml Red Wine
  • 750 ml Beef Stock
  • 400 g Tinned Tomatoes (1 Tin)
  • A Few Sprigs Of Fresh Rosemary & Thyme (Tied Together)
  • 1 Bay Leaf

To Finish

  • 2 tsp Worcestershire Sauce
  • 2 tsp Balsamic Vinegar

Instructions

Ragù

  • First, chop the leftover prime rib into 1 inch chunks then set to one side.
  • Peel & finely dice the onions & carrots. Dice the celery as well but there's no need to peel - just make sure they're clean. Grate the garlic now as well but set to one side.
  • Next, set a large saucepan over a medium-high heat, add in the vegetable oil then leave to heat up for a minute or two. Once hot, add in the chunks of prime rib then cook for 3-4 minutes, stirring often until well seared.
    Make sure not to overcrowd the pan. If needed, sear the beef in batches.
  • Once seared, use a slotted spoon to transfer the beef to a bowl, leaving the rendered fat in the pan.
  • Turn the heat down to medium then add in the diced onion, carrot & celery, along with a pinch of salt then cook for 4-5 minutes until soft. Make sure to stir the veg frequently. When the veg is cooked, add in the grated garlic then cook for another 30 seconds.
  • Next, stir in the tomato paste, cook for a minute then pour in the red wine, scraping the bottom of the pan with a wooden spoon/spatula to deglaze.
  • Let the red wine reduce by about two thirds then add in the beef stock, tin of tomatoes & herbs. Add the seared beef back in then season the sauce with salt & pepper.
  • Turn the heat down to medium-low, cover the pan with a lid then gently simmer the ragù for 2-2½ hours until the beef is tender. You need to be able to shred it easily.
    To test the beef, lift a piece out of the sauce then use 2 forks to see if you can pull it apart.
  • Once the beef is ready, use a slotted spoon to lift it out of the sauce & onto a tray. Set this aside for now. Take the herbs out of the sauce now as well; they can be discarded!

To Finish

  • Turn the heat back up to medium then bring the sauce to a simmer. Cook for another 20-30 minutes, until the sauce is thick & has reduced by around 50%.
  • Whilst the sauce is reducing, shred the beef into bitesize pieces (not too small!). You can do this with forks or by hand (wear food safe gloves).
  • Once the sauce has reduced, stir in the Worcestershire sauce, balsamic vinegar & the shredded beef. Cook for another couple of minutes, to let the flavours meld together then season to taste with salt & pepper.
  • The ragù can be served straight away or you can leave it to cool then store in the fridge for up to 3 days & reheat to serve. It will taste even better if you let it chill in the fridge overnight!

Notes

1. To Cook In An Aga - Use the boiling plate to sear the beef, to cook the veg & to deglaze the pan. Move over to the simmering plate once you've added in the stock & tomatoes, simmer for 10 minutes then cook on the floor of the simmering oven until tender (around 3 hours). Reduce the sauce on the boiling plate.
2. Leftover Prime Rib - For this batch of ragù, you'll need 800 g of leftover roasted prime rib. However, you can make half a batch, using less beef if required. I used leftovers from my reverse seared prime rib. The timings for cooking the ragù are based on the leftover beef being cooked pink (medium rare - medium). If yours is cooked more than this, it won't take as long to cook.
3. Beef Stock - You can use a homemade beef stock or a good quality stock pot/cube dissolved in hot water. I had 500ml of leftover bone marrow gravy, which I made up to 750ml with water!
4. Tinned Tomatoes - A good quality tin of chopped tomatoes works best for this recipe. You could use plum tomatoes but you'll need to break them up with a spoon as they cook.
5. Storage - Once cool, this prime rib ragù will keep in the fridge for up to 3 days, or in the freezer for several months. The flavour of the ragù will be even better if you let it chill in the fridge overnight before using!
6. Serving - This recipe makes plenty of ragù; enough for 8 people! I served half of mine with 500 grams of gnocchi but it's good with pasta, in a lasagne or even in a pie or on a pizza. To reheat, warm the sauce back up in a pan over a medium heat. It needs to be piping hot!
