Syn Free Roast Beef and Gravy | Slimming World

This Syn Free Roast Beef and Gravy is perfect for a Sunday afternoon. Why? Because it has syn free gravy!

One of the questions we get asked most often is probably “Do you have a recipe for syn free gravy?” We do have a Meatballs & Syn Free Gravy recipe. While that gravy is ideal for meatballs, it’s just not quite right to serve with a roast dinner.

For the full list of ingredients and comprehensive instructions, please see the recipe card at the end of this post. Before you scroll, there’s important stuff in the blurb 👍

So we thought why not try making the stock for the gravy while you’re roasting your joint of meat. We tried, and this Syn Free Roast Beef and Gravy recipe was created.

Roasting the meat

You can use this recipe for whatever meat you prefer, and we’ve added a table for you to easily see how long to cook it for.

The best way to check if your meat is cooked is to use a digital kitchen thermometer, which you can pick up from Amazon. Ours is used almost every day, especially during BBQ season!

If you’re cooking chicken always double check the temperature by sticking the thermometer in a few different places, specifically the thighs and breast, and check for the lowest temperature.

We use a roasting tray with a trivet inside, and you’ll find them on Amazon. However if you don’t have a trivet you can just roast the meat on top of the vegetables.

Resting the meat

You should always rest your meat before carving. For roast joint you should allow 10 to 20 minutes. Just put the meat in a warm place covered with foil, and the meat will be juicier and easier to carve. Plus it will use less juice when you cut into it.

Making the Gravy

Trying to find a good syn free gravy is like trying to find hens’ teeth. It seems to be the Holy Grail of the Slimming World Community, second only to a good Slimming World friendly cake recipe.

There will probably some people that would consider this gravy a tweak due to the blitzed potato. However, because of the other blitzed veg this gravy is quite filling and satisfying in it’s own right, so it’s not likely you will over eat it.

Also it will be served with a roast dinner containing a load of speed veg, in the same way as the Slimming World Mushy Pea Curry which isn’t considered a tweak.

To make a good gravy you need a good stock, but sometimes using those meat juices can add a lot of fat and hidden syns to a recipe. We like to use one these fat separators.

Just pour the stock in straight from your roasting tray, then pour it out through the spout, and all the fat will remain in the jug.

This means you can get all of those juicy, meaty flavours, but none of the excess fat. They are a great kitchen gadget, and you can get them from Amazon.

One more thing to point out is the recipe for Syn Free Roast Beef and Gravy has the option of using gravy browning.

Now, if you check the Slimming World app then you will see that 2 tsp are worth 2 syns.

In this recipe we are literally using 2 or 3 drops so we don’t bother synning it. But having said that, the choice to syn or not it is yours, and yours alone.

  1. Place the chopped veg on the bottom of a decent sized roasting tin
  2. If you have a trivet place it over the vegetables and put the beef on top. If you don't have one you can just place the beef joint on top of the veg
  3. Season the beef well with sea salt and freshly ground black pepper and give it a massage!
  4. Pour 500ml of water into the tin to cover the veg (this will make your gravy so don't let it evaporate in the oven)
  5. Cook for the desired time (see the table above) at 180°C/gas 6
  6. At the end of cooking time check the joint with a meat thermometer (see the table above) and if it's ok remove it from the oven to rest
  7. In the meantime scoop out the veg from the liquid, then pour the stock into a fat separator (more info above)
  8. Pour the stock out of the separator into a bowl, leaving any fat behind
  9. Add the cooked veg to the stock, and 2 stock cubes
  10. Blitz in a food processor until smooth. If it's too thick add a little more water, and a few drops of gravy browning if you're using it
  11. Stir well and serve. Or you could let it cool and either freeze it or keep in the fridge until you're ready to use it

  1. I can’t wait to try this! I normally add a splash of balsamic vinegar for colour and taste rather than gravy browning, it’s free too 🙂

  2. I like to print out my favourite recipes, most of them are Pinch of Nom!
    In order to cut down on the paper use could you consider reducing the print size of your heading to enable mostt recipes to use one page?

    1. Hi Chelle
      We’re currently very busy developing lots of new recipes so that takes priority over the print button. It’ll be fixed when we have the chance to get round to it 😊

      You could bookmark the page on your browser so you’d be able to find the recipe quickly 😊

    1. Hi Barbara
      Our Syn free gravy recipe can be made vegetarian if you choose vegetarian stock cubes/stock pots. The Sarsons gravy browning is used to give the gravy a darker colour and only lists Ammonia Caramel, Glucose Syrup, Salt as it’s ingredients. It does not contain meat derivitives. Hope that helps.

    1. Hi Vicki
      You can cook a joint of beef in a slow cooker, yes! Cook on low for 6-8hrs, and sit the beef joint on a few roughly chopped carrots and onions.:-)

  3. I will try this gravy recipe and let you know. I have been known to add a little brown sauce to add more flavour or just used onions, also just ordered the recipe book,which I can’t wait to try
