Syn Free Lasagne | Slimming World

We love lasagne, sadly, as with an awful lot of our favourite things, it’s not very Slimming World friendly. So we decided to make this Syn Free Lasagne.

A classic Lasagne is made by interleaving layers of pasta with layers of bolognese sauce, usually consisting of minced beef and tomatoes.

The Bolognese Sauce

The secret to a good Italian sauce is to use a good quality tomato. We used Cirio Cherry Tomatoes, but any good quality Italian tomatoes is fine.

They’re not as watery or acidic as some other brands, and they are great when you want that authentic Italian tomato flavour.

The White Sauce

Recently a lot of people have asked us how to make a white sauce for lasagne. We’ve tried quite a few versions of this sauce, from blitzed cottage cheese to quark, but this is probably the best one so far. So it’s well worth giving it a go.

This Syn Free Lasagne uses half of your HEA allowance if you get 6 portions out of this recipe. However, if you don’t want to use up your HEA you can always syn the cheese.

  1. Could also make this using leeks instead of the pasta sheets. Cut the leek down one side so you can spread each layer of the leek flat and use them. It’s delicious.

    1. Yes you can, but you may need to put some extra chopped tomatoes in there. I find that sometimes lasagne can be a little drier after freezing.

    1. You can get Cirio tomato products from most supermarkets, apart from Asda I think. They are quite often on offer too! They are definitely my favourite ones to use, but you can easily use other brands too

  2. Excellent recipe. My kids love it too.
    Easy to follow – a great version of a classic recipe.

    One I have used on more than one occasion. I personally don’t add courgette or pepper … it’s lovely either way.

  3. This is by far the best lasagne recipe ever (even better than the original in my opinion and so much healthier) loved the white sauce I even converted my mum who’s doesn’t like lasagne after trying a portion she’s now converted .Thank you x

  4. Hello

    Is there any way of doing an individual lasagne? The measurements are hard to divide for a single portion.

    Thanks in advance!

    1. Hi Jody
      Yes you can do this, however, it’s important to remember that SW consider this a tweak. Thay say that even though Macaroni Cheese is already synned when used as intended it is given a Free Food allowance because it contains bulky, satisfying pasta. Once blended, it is not as filling and it just adds extra calories to what would otherwise be a really slimming Food Optimising meal.

  5. Loved this lasagne. I used the butternut squash sheets instead of pasta.Is now a firm family favourite.
    Thank you so much for this recipe!

    1. Hi Jo
      You may find that the quark will split and curdle if you use it on it’s own, but you could probably use half yogurt and half quark

  6. Hi, tried your lasange receipe, very good only thing was the elite sauce make according to instruction but it had a spongy omolette texture used 0% fat free Greek yogurt, any tips for to make it creamy

    1. Hi Linda
      We use eggs in our version of white sauce to replace the higher synned white sauces. You might find that only using 1 egg rather than 2 would give a less ‘omelette’ texture.

  7. LOVELY, thank you ladies for sharing this recipe. The whole family enjoyed it and have enough for another meal time, so double whammy! I take it i can freeze it 🙂 x

  8. Hi There – This looks amazing! Im Canadian – what is tomatoe puree? Ive spent 20 minutes looking this up? is it tomatoe paste? tomaote passata? Im confused. Can anyone let me know before my grocery run in a few hours? Thanks

  9. This is one of my favourite recipes, i vary it sometimes by adding b squash etc and also have also added a glass of red wine and synned it when family are round.

  10. I made this last night and it was absolutely gorgeous! Thank you! I chopped everything in the Magimix so it really was very very easy and the yoghurt and cheese topping was lovely. This really didn’t taste like a diet recipe. Will be adding this to my regular list and can’t wait until tonight for the leftovers.

  11. hi
    not sure what im doing wrong but made this twice now and both times the egg has cooked like scrambled egg help please

    1. Hi Bev
      Yes, the prep can sometimes be time-consuming, but it’s worth it! Once you’ve made it once, you’ll speed up too! 🙂

  12. Hi I’ve just made this and split it in half between 2 goil takeaway style tins. Can I freeze it before the final oven cook stage or is it best frozen when completely cooked then chilled? ?

    1. Hi Jules
      You build the layers of meat and pasta and add the sauce on top. All details are on the recipe card, scroll on past the recipe for details. 🙂
