Slow Cooker Butternut Squash and Lentil Lasagne #SlowCookedChallenge

Slow Cooker Butternut Squash and Lentil Lasagne #SlowCookedChallenge

As the weather slowly improves and the start of Spring appears to have finally arrived, I like to enjoy comfort food still but with a healthier twist. My slow cooker butternut squash and lentil lasagne is a great filling veggie slow cooker dish and works well for a healthy eating plan too as it is based on vegetables. There is no pasta here, I’ve replaced it with slices of butternut squash and courgette. Topped with ricotta cheese and a little extra mature cheddar, this dish is full of flavour and perfect for a chilly but sunny Spring day.

Slow Cooker Butternut Squash and Lentil Lasagne

The layers of butternut squash and courgette do a great job in place of sheets of lasagne. They keep their bite and I season them well for loads of flavour. You can buy butternut squash in sheets from some supermarkets, or do what I did and buy it in large pieces and then just make into thinner slices for layering. I just sliced the courgette carefully lengthways with a knife or you could use a mandoline if you have one (and don’t mind losing the odd finger here and there…). The tomato sauce with green lentils adds flavour and depth and makes this suitable for a main meal. I often make vegetarian meals in my slow cooker, have a look in my Recipe Index to see more of them.

For the lentil tomato sauce:
  • 1 onion
  • 1 clove garlic large
  • 1 tin chopped tomatoes 400 g
  • 0.5 tsp dried thyme
  • 3 leaves fresh basil torn
  • 1 tin green lentils 410 g tin, 265 g drained
For the vegetable layers:
  • 500 g butternut squash sliced
  • 3 courgettes (zucchini) large, approx 375 g, sliced lengthways
  • 3 leaves fresh basil torn
For the cheese sauce:
  • 250 g ricotta cheese
  • milk a splash
  • 50 g extra mature cheddar cheese grated, I used 30% lighter cheese
  1. Spray you slow cooker pot lightly with oil to prevent sticking.

  2. Mix the ingredients for the lentil tomato sauce in a large bowl. Place half of the sauce in the base of the slow cooker pot.

  3. Add a layer of courgette to cover the lentil sauce. 

  4. Add a layer of butternut squash to cover the courgette. Season with salt and pepper and add some more torn basil leaves.

  5. Repeat, first adding the best of the lentil tomato sauce, then a layer of courgette and another layer of butternut squash, and seasoning/basil.

  6. Put the ricotta cheese in a small bowl, add a splash of milk to thin it slightly. Put half of the grated cheese in the ricotta and mix.

  7. Spread the ricotta cheese mixture over the top of the butternut squash slices. Top with the remaining cheese. Season with salt and pepper and add a little more basil.

  8. Cook on high for 3 hours. Then take the lid off and cook for another hour on high to reduce the liquid in the pot.

  9. Allow to cool slightly then slice and serve using a wide spatula.

Recipe Notes

For this recipe I used a large 5.7 litre slow cooker.

If you follow or take part in the Slow Cooked Challenge you will have seen the sad news that Janice from Farmersgirl Kitchen, who started this linky in 2013, has hosted her last instalment of the challenge as she no longer has the time for the challenge and all the work it involves. I’ve been hosting the challenge with Janice for a year and a half I think now and she very kindly has allowed me to continue it and hopes to take part when she can. So I am very pleased to continue the Slow Cooked Challenge and hope to be able to do it justice!

Aw thanks Lucy, so nice to see the Slow Cooked Challenge continuing. Love your butternut squash lasagne, such a good idea. I hope to be back to link up soon.

Looks so good & healthy … !! I’ll definitely go for this slow cooker butternut squash lentil lasagne. I love butternut recipes. Thanks for this one…!! 🙂

What a perfectly brilliant idea to use squash instead of lasagna for layering. I bet this was delicious. I love lentils.

This is absolutely my kind of dish. I don’t make veggie lasagnes often enough but now the kids are older I’m going to be trying out more veggie dishes and I am sure they would give this one a thumbs up as much as me!

It looks delicious! I really need to have a go at something like this in my slow cooker! I haven’t used it for a few weeks now and sometimes get stuck in a rut of doing the same meals in it rather than something new. Thank you so much for sharing with #CookOnceEatTwice!

Oooh Lucy this lasagne looks and sounds so delicious! I love lentil lasagne. I am doing a slow cooked meal tomorrow I will remember to link it up. Thank you for sharing with #CookBlogShare x

I’m in, it looks great! Thanks for submitting it to Meat Free Monday. The roundup is now live and your recipe has been featured.
