This simple vegan Alfredo sauce is super creamy and wraps thick ribbons of tagliatelle in a delicious savoury coat. Vegan Alfredo sauce is usually made with cashew cream but I’ve had a few requests via my Facebook page for more economical vegan food so, today, I am sharing my recipe for sunflower cream instead!
Using Sunflower Seeds For Vegan Cream Sauces
Sunflower seeds are readily available in supermarkets and wholefood stores, they are at least half the price of cashews and are a more sustainable choice for those trying to cut down their food miles.
They are also rich in B vitamins and are a good source of protein but, far more importantly, they make a fabulous sunflower cream which tastes just as good as the cashew version!
Vegan Cream Sauces
Vegan cream sauces were one of those amazing revelations when I first went vegan – my family couldn’t tell the difference between dairy cream and vegan cream in cooking!
The only noticeable difference is that vegan cream doesn’t leave us with that heavy, slightly nauseous feeling we had after a dairy cream meal had been consumed.
My eldest is dairy intolerant so a whole new world of recipes opened up before him when he chose the vegan life in 2015. I can’t wait to pop this vegan pasta Alfredo in front of him when he returns from Berlin next week!
Pasta Toppings
I topped my pasta Alfredo with cavolo nero and cherry tomatoes – I like the way the acidity and sweetness of tomatoes cuts through the creaminess of the Alfredo sauce and I always try to include something leafy and green with my meals – goodness, how I love kale! They were very gently fried together in a little olive oil with some salt and a little black pepper. You could stir them through your pasta but I plonked them on top because they look so pretty!
How To Get A Cheesy Flavour In Vegan Pasta Dishes
If you’re new to vegan cooking the only ingredient here that you may not have come across is nutritional yeast.
Nutritional yeast is the (not so) secret magical vegan ingredient to add a savoury cheesy flavour to vegan food.
I buy mine at my local wholefood shop but you can also buy it in Holland and Barrett or online.
I would thoroughly recommend that you invest in a pot of the lovely stuff and that you buy the one which contains B12 which is the only vitamin which can be tricky to find in a vegan diet – this and a jar of Marmite will sort you out!
Apart from that, I think the rest of the ingredients should be pretty familiar to you all! I have used oat milk in my vegan Alfredo sauce but you could use any plant milk in its place.
How To Get A Smooth Sauce
While this recipe is very simple, and you can make it using a food processor, you will only get the smooth creaminess with a high speed blender.
A high speed blender is a really good investment if you are going to be cooking a lot of vegan meals. It’s great for soups, smoothies, sauces, spreads and dips and I use mine almost daily!

That’s a fab tip about using sunflower seeds Chris. Cashews used to be much cheaper than they are now, but your point about food miles is a good one too. Looks delicious and I’m sure your eldest is going to be very happy with it 😀
I think he is! He always has a very long list of favourites he would like to eat when he gets home 🙂 Luckily, he is a very good cook so I’m hoping for a few new recipes from his travels to add to our collection!
This looks amazing! I think it be perfect for a date night dinner.
And super simple! Good plan!
That looks so good. I’d happily tuck in. YUM! Sharing this x
This is genius! We are really enjoying our foray into veganism so far. Will definitely give this a try!
Wow! I never knew sunflower seeds could transform into such a creamy sauce! I’m always on the look out for budget-friendly vegan recipes so I’m excited to try out your recipe as a replacement for cashew alfredo.
p.s. LOVE your tomato and cavalo nero toppings. They’re so pretty!
I’d heard of cashew cream but hadn’t really thought about using other nuts and seeds to make lighter versions. I love the idea of using sunflower seeds. This looks wonderful and definitely something I would like to try.
Such a delicious looking plate of pasta!
Thank you Janice!
Wow – swift and delicious. Great to be able to make great food with store cupboard ingredients. A winner. I will be making this again. Thank you for the inspiration! x
