Recipe: Creamy Vegan Lasagne Sauce

Creamy Vegan Lasagne Sauce

Veganuary-heartThis is my last Veganuary post as the month draws to a close, (though there will be lots more vegan recipes coming up, don’t fear!), and I thought I would share one of my very favourite “but surely that can’t be vegan” meals, my super-duper vegan lasagne.

The big surprise is the intensely creamy, velvety, even (dare I say) “cheesy” sauce layer, for which the recipe is below.  For the other tomato-ey ‘mince’ layers I used a batch of my Slow-Cooked Borlotti Bean Chilli from the freezer, bulked out with some soya mince and extra veg to make it stretch a bit further.  

Creamy Vegan Lasagne Sauce 2The creamy sauce uses a now very common trick to get that lovely texture – the inclusion of a whole cauliflower.  I know, it sounds a bit crazy, but don’t knock it ’till you’ve tried it.  If you imagine the creamiest cauliflower soup you’ve ever tried, then add some soya or nut milk and secret vegan cheesiness powder (more below on that one), that’s this sauce.  Type ‘Cauliflower Alfredo Sauce‘ into Pinterest and you will see the near-obsessive use of cauliflower to recreate velvety creaminess of a simple cheese sauce, without dairy.

I’m not a fan of wierdo vegan ingredients which involve a tour of your local health food shops to find, (chia seeds in my Ultimate Vegan Victoria Sponge last week were a bit of a stretch, but really vital as an egg replacer).  But nutritional yeast flakes really are worth tracking down for their uncanny ability to make just about anything taste ‘cheesy’.  They are also incredibly good for you with all sorts of vitamins and minerals including the elusive B12 which is one of the hardest to get into a vegan diet.

Creamy Vegan Lasagne Sauce 3I used Marigold’s Engevita Flakes, but If you can’t find any really don’t worry, the sauce will still be delicious without, just a little less ‘cheesy.  Make sure you adjust the seasoning accordingly, you may need a little more salt.

Of course this sauce isn’t just useful for lasagne, you can substitute this in pretty much anywhere you would use a béchamel or cheese sauce – pasta bakes or macaroni ‘cheese’, dauphinoise-style potatoes, vegetable gratins, the possibilities are endless.  This makes 1 litre of sauce, so easily enough for a lasagne for 2, then keep half in the fridge for another night, perhaps with some of the alternative flavourings suggested below for variation.

The great thing about including a whole cauliflower is that the sauce is deceptively ‘light’ – a litre of real cheese sauce would contain, well, a litre of milk or cream, plus lots of cheese.  A litre of this is so much lighter and easier on the gut, that you can eat twice as much lasagne.  Yes, that’s right – go vegan and you can eat twice as much lasagne.  You heard it here first.

Recipe type: Main
Cuisine: Lasagne
Serves: Makes 1 litre sauce
Ingredients
  • 2 tbsp olive oil
  • 1 onion
  • 1 cauliflower, cut into small florets.
  • 3 tbsp flour (sauce flour or just plain flour will do)
  • 800ml soya or nut milk mixed with water (I used a 50/50 mix here, 400ml milk and 400ml water, but for an extra creamy sauce use all milk, and for a very low-fat sauce use 200ml milk and 600ml water!)
  • 2 tsp stock powder
  • 4 tbsp nutritional yeast
Instructions
  1. Heat the oil in a large saucepan, add the onion and fry gently for 3-4 minutes until soft. Add the cauliflower, cover with a lid and cook for a further 3-4 minutes.
  2. Sprinkle the flour over the cauliflower, then stir. Pour over the milk and water, and add the stock powder.
  3. Bring to the boil, then reduce to a simmer and cook for 15 minutes until the cauliflower is soft. (Don't worry too much if there are some lumps of flour, these will disappear when blended).
  4. Tip the cauliflower and sauce into a high-speed blender, (or use a hand-blender in the saucepan), add the nutritional yeast flakes and season well with salt and black pepper. Blitz for 40-50 seconds until completely smooth and creamy.
 

You can add all sorts of wonderful flavourings to it for added interest, such as:

  • Roasted Garlic – wrap a whole head of garlic in foil and bake for 30 minutes.  When cool, squeeze the sweet flesh out of each clove and add to the blender.  All the sweetness with none of the death breath!
  • Curly Kale – Add a large handful of kale or spinach to the saucepan whilst the cauliflower is cooking for a bright green sauce.
  • Wholegrain Mustard  – just add one tablespoonful to the blender.
  • Dairy-free Pesto – my favourite is Mr Organic’s Basil Pesto, add a tablespoon of pesto to the blender.
  • Lemon & Fresh Herbs – basil, parsley or thyme, with the zest of a lemon would be really lovely additions.
  • Sun-Dried Tomato – a tablespoon of sun-dried tomato paste added to the blender really perks up a Mediterranean- style lasagne.

  2. Your sauce and tweaks sound delicious, Kate. I use “nooch” a lot to make similar types of “cheesy” sauces although, like you, I don’t really go for any of the manufactured vegan products (I do make an exception for vegan chorizo though – the real thing was a taste of my childhood).

  3. As a lapsed veggie when I was younger, who has never tried a vegan diet, this sounds good enough to make me want to try vegan lasagne! I mean, if you can have twice as much as well, who’s to argue! I love cauliflower and the added garlic or pesto sounds so good.

  4. This sounds great, could work well for Chloe who can’t have dairy, gluten or soya so I would use a nut milk and sauce/corn flour as you recommend. X

  5. This looks fantastic! Thank you so much for linking to my recipes!
    I love using cauliflower to make creamy sauces, what a wonder veg!

    1. Thanks Poppy – yes I’m still finding out about how many ways you can cook cauliflower, its amazing!!

  6. Do you think this vegan lasagne sauce would freeze?? Thanks

    1. Hi Carol,

      Yes this would definitely freeze well, great idea!

  7. Looks amazing!! What is stock powder?

    1. Thanks Heather! Stock powder is what you add to boiling water to make an instant vegetable stock – sometimes called bouillon powder. Perhaps its a British thing? However you would usually make vegetable stock/bouillon will work fine!
