Nigellas sweet potato macaroni cheese (slimming world friendly )

This is proper comfort food so warming and filling and although its not syn free I have adapted the recipe to keep it as low syn as possible but keeping all the tastiness of the original recipe. The recipe serves 4 but you could easily make it serve 6 if served it with something like Slimming World sausages and vegetables.

Nigellas sweet potato and macaroni cheese

500g sweet potatoes (peeled and cut into cubes)
300g dried macaroni
2 tbsp cornflour
500ml skimmed milk
1 tub quark
160g reduced fat cheddar cheese (grated)
1/4 tsp paprika
salt and pepper

Preheat oven gas 6 /200/400. Put a large saucepan of water on to boil and add a tsp or two of salt once boiling add the sweet potato and cook for about 10 minutes then take out the sweet potato with a slotted spoon and put into a large bowl, Keep the water boiling and add the macaroni and stir well and cook for 8-10 minutes until cooked but still quite firm then drain in a colander.

Using a fork mash the sweet potato in the bowl till mashed but not pureed. Add the tub of quark, the cooked macaroni and 100g of the grated cheese and mix well.

In a saucepan place the milk and the cornflour and bring to the boil, Keeps whisking all the time until the sauce is thick and cook for a couple of minutes to lose the floury taste. Season with salt and pepper then add to the sweet potato, macaroni and cheese mixture and again mix together very well. Taste for seasoning  (I found it needs quite a lot of salt and pepper. )

Tip it all into a large casserole dish and sprinkle the remaining 60g of grated cheese on top and sprinkle on the quarter tsp paprika,

Place the casserole dish on a baking tray and bake in the oven for 30 minutes until browned and hot.

Serves 4 at 3.5syns per portion if using the cheese for your Healthy Extra.


  1. Do you run the face book page
    because there seems to be a lot of your pictures on there if you don't. Love your blog by the way xx

  2. Hi Katrina, No I don't they use my recipes on their blog but they give me a small credit so there is nothing I can do about it unfortunately.

    1. You own the copyright of anything you post. If someone else uses it on their page, then send them an invoice.

  3. Hi Vicki, Thank you for posting this recipe, I have just enjoyed it so much. It has taken me back to my childhood when my mum used to make baked macaroni cheese (without the sweet potato). Hubby loved it too, he didn't even know there was sweet potato in it as he doesn't like it lol!

  4. I had my doubts, but this was so tasty! Thank you for sharing. Is it suitable for freezing?

  5. To be honest I haven't tried freezing it but if you try it let me know, Happy you like it all my recipes are tried and tested on my family first :)

  6. We made this tonight for supper and it was ABSOLUTELY DELICIOUS!! YUM! Definitely a new favourite! I was wondering though how many syns it would be if you didn't use the cheese as your healthy extra?

    1. So happy you like it, 40g reduced fat cheddar is 6 syns so it would be 9.5 syns per portion. Thanks Vicki

  7. How much is a tub of quark ??
