This vegan cauliflower Alfredo sauce with tofu is incredibly savoury, rich and creamy, with the perfect hint of cheesiness. It's delicious served with pasta as a wholesome dinner that's ready in around 15 minutes. Gluten-free and dairy-free.
Who else loves all things cauliflower? I do for sure - it's such a versatile ingredient that never seems to get boring. You can use it for sauces, soups, pizza bases, even desserts. It's one of those ingredients that's neutral in flavour on its own and therefore works in a whole range of recipes, whether sweet or savoury.
Today, we are using it for a sauce. More specifically, an amazingly creamy and smooth Alfredo sauce that is so perfect with pasta - and you won't believe just how easy it is to make!
About this vegan cauliflower Alfredo sauce
If you've never used cauliflower in a sauce before, I would 100% recommend it. On the one hand, an Alfredo sauce made with vegetables, much like my roasted red pepper pasta sauce. So it won't taste exactly like classic Alfredo sauce, which is made with cream and butter, and thus people who haven't been on a plant based diet for a long time may be able to tell a slight difference.
But, this recipe is 100% non-vegan approved. Thud anyone can enjoy this with some fettuccine or spaghetti, regardless of their dietary preference. That's given the smooth texture and the tastiest savoury flavour that may become your new favourite way to eat more vegetables!
There is, however, another secret ingredient in this cauliflower Alfredo. And that is tofu. Much like the cauliflower, it has a neutral flavour and helps to create a thicker texture. Then, all you need is a few more simple ingredients for comfort food perfection.
How to cook cauliflower
There are a few ways you can cook cauliflower for this recipe. You can either boil it in a large saucepan for around 8-10 minutes, or steam it in a steamer basket. I would recommend you steam it for around 10 minutes so it is very soft and results in the creamiest sauce.
