  7. Spread a layer of the mince mixture on the bottom of a decent sized oven proof dish, then add a layer of Butternut Squash Lasagne sheets, then repeat until you reach the top if the dish, ending with a layer of lasagne sheets. make sure you leave enough room for the sauce

    1. Hi Caroline
      We tend to only put the white sauce on the top, but there’s nothing to stop you layering with the meat and squash sheets

  1. I made this as I bought the butternut squash lasagne sheets in Sainsbury’s. After reading the recipe I honestly thought this was going to be one of those meals you make which you look forward to but tastes vile. (I have made many of these in my time). Once made I froze all the portions as I wasn’t that excited about what I was going to eat. Took one out for dinner last nite I was shocked! They are honestly as good as my heart attack lasagne I normally make. Can’t wait to have more. Thank you for the recipe!

  2. I am vegetarian so will be using quorn mince. My question is about the eggs. I really don’t like them, would it taste ok not to have the eggs in the sauce?

    1. Hi Rosie
      The eggs stabilise the sauce, so leaving them out might make it a little more runny, but there’s no need to add them as long as you don’t mind that.

  3. Possibly a blonde question, when are you adding the aubergine? Is it added to the cooked mince mix or as a layer on its own?

    1. Hi Buddy
      The pureed aubergine is added along with the courgette, peppers and mushrooms in step 5 of the instructions

  4. Hi
    Can we make the pasta sheets from a large butternut squash? Trying to work out what to do with it.

  5. Hi ๐Ÿ˜€
    Made this last night and I would like to thank you for such a delicious recipe. It was truly amazing and I have shared it with all my slimming world friends. Took leftovers for lunch today and my partner is having it tonight! Love your group and fantastic ideas ๐Ÿ˜‹๐Ÿ˜‹๐Ÿ˜‹xxxx

  6. Hi,

    I want to make an SP version of this lasagne, could I switch the yogurt for quark? Or would it be better to just leave out the white sauce?

  7. I made this with regular sw bolognese sauce and substituted some of the yoghurt (about a third) for quark. I also added nutmeg to the sauce, which I put poured on each layer of the lasagne, not just the top layer. I added some grated Parmesan to the top layer of sauce.along with some reduced fat cheddar as I love it. It worked a treat, the whole dish is delicious and very similar to a pasta lasagne. One small difference is you do get some water on the plate from the butternut squash that needs to be cleared up but otherwise this is a fab dish. I will definitely be making it again!

  8. This dish tastes amazing ๐Ÿ˜€ I can see it becoming one of my regular meals! However, I did a few tweaks :O

    I roasted the butternut squash – cut in half and in a roasting dish with some water (didn’t buy expensive pre cut slices :O ) – for 40 mins.
    I also roasted the beef for the same time … a la Tom Kerridge ๐Ÿ˜€
    The aubergine roasted, as per recipe for 30 mins – I didn’t puree the aubergine … why waste all that lovely skin? I chopped it.
    The courgette and peppers were also roasted but only for 20 minutes tops.
    Otherwise I stuck to the recipe directions ๐Ÿ˜€ Loved it, thank you so much for coming up with this ๐Ÿ˜€

  9. Hi, I am going to try this recipe but have a question. What temperature should your oven be set to when you roast the aubergine?

  10. Hi, I changed to yoghurt for quark, which removed the SP forbidden item and it was still delicious. A possibility?
