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!

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 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 and I can’t wait to pop this vegan pasta Alfredo in front of him when he returns from Berlin next week. 

Pasta Alfredo with Vegan Alfredo Sauce, Kale and Tomatoes

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! 

Cherry Tomatoes and Cavolo Nero

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 on line. 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. 

Vegan Alfredo Sauce with Tagliatelle, Cherry Tomatoes and Black Kale

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!

If you are planning to cook lots of vegan recipes (and why wouldn’t you, look at all the tasty possibilities!)I would recommend investing in a good high speed blender. I made my vegan alfredo sauce in my Optimum G2.1 which makes short work of sauces and soups and makes my cooking a much easier process! 

So – on with the recipe!
