As you know, I’m naturally drawn to spices; Indian and Middle Eastern food makes my belly happy and my soul excited, so I fill my days with nothing but these delicious dishes!

But it also means that sometimes I can forget just how delicious Mediterranean food can be. I particularly love Italian flavours–they are renowned for not only their quality cooking but for their ultimate passion and communal rituals and love they pour in every dish.

They also utilise home-grown produce, (which is something that is super close to my heart) that is just bursting with fresh farm-to-table flavour and authenticity.

My heart (and belly) is often fond of a superb and rich tomato sauce, you know the kind, the ones that make you want to lick the plate clean and savour every bountiful flavoursome forkful–especially when paired with a drizzle or two of a high quality olive oil and fresh sourdough.

But it’s been absolutely years since I last ate or even made lasagne, so I just knew that had to change ASAP.

Like a lot of Italian dishes, lasagne evokes fond memories; my mum used to make the most delicious lasagne and as I recreated that layer by layer, it reminded me just how therapeutic and delicious the combination of soft but with a slight bite al dente style pasta, melting and oozing ‘cheese’ sauces and a whole variation of seasonal veggies could be.

So I present to you my homage to the Italian classic–my Vegan version of Lasagne packed with lots of vegetables, red lentils, a creamy ‘cheese’ sauce and to make it even more special I’ve layered it with the most deliciously fresh and zingy spinach and walnut pesto, that you are going to want to put on EVERYTHING!

I made this for my friends the other night after telling them all about my newest creation and they loved it just as much as I did!

Phew! I can always rely on them to give honest (sometimes too honest) feedback, so I’m counting this one as a winner!

This dish takes a little of time to make each component right, from the delectable and rich tomato and lentil filling, to the oozy cheesy sauce, but each step is super simple and oh so worth it.

You can even make this dish the night before–the flavours improve overnight as they soak into all the wonderful vegetables. Cook all the distinct elements the night before and assemble and bake on the day, or bake the day before and re-heat. Both work just and each other.

Unlike most of my dishes, this one doesn’t freeze that well. But portioned in the fridge and re-heated the next day works amazingly, especially when served with a light and fresh salad.

And another bonus about this recipe is there are so many variations and substitutions you can make depending on your likes, preferences and ingredients.
If you cannot eat or find onions, swap for leeks.
Add in courgette, peppers or your favourite vegetables to bulk out the meatier sauce and get your five a day in one hit.
Swap the red lentils for green, black or your favourite pulse.
Swap out fresh basil, for any other fresh green leafy herb, or use spinach instead.
And, of course, the dividing ingredient — mushrooms! This works just as well with or without them, personally I love the texture they give, but omit or replace with aubergine for the same textural mouth-feel if you aren’t a fungi fan.

I’d recommend making extra of your spinach and walnut pesto and to keep in the fridge. You can stir it into gnocchi, pasta or risotto, generously slather on top of freshly baked sourdough, or use as the base on a pizza bread. Or just eat it straight out of the jar. It can be our little secret!

    This tastes amazing. However… it’s taken 1 hour to cook! The lasagne sheets were still hard, so I I just kept putting it in the oven for extra 10 minutes at a time and checking. We didn’t eat until 9.30pm. I think the lasagne sheets definitely needed blanching.

  2. Hi Niki.

    Just cooked this for the family and loved it, thanks for the recipe !! Also, any idea on calories per portion (long shot I know)

  3. Hello! I love the look of this lasagne. I’m sorry I’m confused (again) about cup measurements. I never use these.

    Can I ask if it’s UK or US cups? If so I’ll work out the recipe measurements if I can find table to convert the different elements. Or do you have the measurements in grams etc? I want to make it this evening and I don’t want to mess up quantities. Thank you soooooo much xxx

  4. Would Plain GF flour work aswell as I need it to be GF.Or a different flour? Can’t wait to try it! Looks delicious!

  5. 5 stars
    This is super delicious!! I used green lentils instead of red, and aubergine instead of mushrooms. My meat eating friends thought it was great!

  6. 5 stars
    This is the most delicious lasagna ever. My ‘carnivorous’ sons said this recipe was the best they have ever eaten. Very very tasty !!

  7. Hi Niki, is the yeast fresh or dry? Is the nutritional yeast the same thing as the beer one? 😉

    Can’t wait to try it out!

    1. Hi Aga
      Its deactivated yeast – which is different to normal yeast. It gives a cheesy flavour. Don’t worry if you can’t find it. You can leave it out.
      Love
      Nikixx

  8. I’m struggling to find fresh basil in my community. Could dried basil be subbed? What would you recommend for th ratio?

  9. This looks great! Could it be assembled and refrigerated the day before needed and then just baked on the day?

  10. This looks and sounds delicious. I will definitely try it when I’ve topped up my stock of walnuts and pinenuts. I can’t wait 🙂

  11. 5 stars
    I added eggplant and used black lentils instead and ooooooomg this was the bomb! Loved the béchamel sauce and pesto, they worked so well together. And just the richness and variety of flavors is amazing! Thank you for this recipe 🙂

  12. Looks sooooo good ! I can’t eat onions, would you leave them out or any substitutes you recommend?

  13. Looks so yum! When do you add he red pepper, zucchini, and mushroom to the onion/garlic mixture?

  14. This looks amazing! I’m going to try and work out how to sub the tomatoes and peppers and make a version of it.

    1. Hi Hayley
      You could sub them for some veg stock. Ie put 1.5 – 2 cups of veg stock instead of the tomatoes, peppers and water.

      Love Niki x

    It has been quite a while since I have made lasagna myself, and I absolutely love it! I really want to experiment with eggplant and zucchini lasagna sometime. I absolutely love your pesto recipe as well–so fresh and beautiful!
