  • 6 wholewheat lasagne sheets (105g)
  • 125g vegetarian buffalo mozzarella, chopped


  1. Heat the oil in a large non-stick pan and fry the onions and garlic for 5 mins, stirring frequently until softened. Tip in the courgettes, peppers and tomatoes with the tomato purée, bouillon and chopped basil. Stir well, cover and cook for 5 mins. Don't be tempted to add more liquid as plenty of moisture will come from the veg once they start cooking.

  2. Lay half the slices of aubergine in the base of the slow cooker and top with 2 sheets of lasagne. Add a third of the ratatouille mixture, then the remaining aubergine slices, 2 more lasagne sheets, then the remaining veg mix. Cover and cook on High for 2½ - 3 hours until the pasta and vegetables are tender. Turn off the machine.

  3. Scatter the mozzarella over the vegetables then cover and leave for 10 mins to settle and melt the cheese, Scatter with basil and serve with a handful of rocket.

Enjoyable, if not a little bland. Easily amended by adding some more herbs and maybe a few chilli flakes! Would definitely recommend getting wholewheat lasagna sheets if you can get them as the white flour ones didn’t have much bite to them. Cheap and cheerful, and a great way to get all your veg in.

Really nice easy healthy recipe, I added some mushrooms to the rest of the veg and used 2 balls of mozzarella instead of 1. Definitely one I will make again!

Could I use emmental cheese instead?? Or mature cheddar??

Thanks for your question. We haven't tested this recipe with alternatives but there is no reason why you couldn't scatter with either grated emmental or mature cheddar. You might want to adjust the quantities.

Mistake in the recipe? The list of ingredients includes 6 lasagne sheets, but the Method only talks about 2 plus 2 sheets, making only 4 in total. I think a step in the Method has been omitted. Please can you correct this omission as I would like to use this recipe again and to make sure I get it right in future? Thanks

Can you cook this in the oven?

Thanks for your question. You could adapt this recipe to go into the oven but as we haven't tested the necessary adjustments we can't give specific advise. We would recommend using one of our vegetable lasagne recipes designed for the oven. You could try this popular alternative: https://www.bbcgoodfood.com/recipes/10603/roasted-vegetable-lasagne

Would this be suitable to separate and freeze spare portions? Any time or temperature recommendations for reheat in the oven (from frozen and defrosted)?

Thanks for your question. We don't recommend this for freezing as it'll be a little but fiddly but you can portion it up and freeze it if you don't mind. We'd suggest defrosting in the fridge overnight and then giving it a blast in the microwave.

Do you use fresh pasta sheets or dried?

Thanks for your question. You need dried pasta for this recipe. Make sure they're not the type that need pre-cooking.

Do the aubergines go in sliced and raw or as part of the ratatouille? I put them in the veg as per instructions and then had none left to line the base of the slow cooker? Was very nice anyway, but needed more mozzarella.
