Best Vegan Cauliflower Alfredo Sauce

Looking for a healthy, hearty, creamy & delicious weeknight meal? You can't go past the comforting flavours of this vegan cauliflower alfredo sauce, paired with wholewheat spaghetti and mushrooms. It's healthy but decadent!

Today is all about my easy, cashew cauliflower alfredo recipe. This bowl of deliciousness was my post half marathon race meal and boy it was so so good, that I decided I had to share this recipe with you! If you are looking for the perfect healthy, plant-based dinner or lunch, then read on...

This recipe is easy enough for a weeknight meal, but also fancy enough for a date night for two. The kind of dinner that hits the spot, without the heavy feeling, of course.

This simple, creamy vegan cauliflower alfredo pasta has and a whole head of cauliflower in it!

Perfect to get the kids eating more veggies without them even knowing. I have served this dish with mushrooms (extra protein boost), whole wheat pasta and some freshly chopped parsley. If mushrooms don't tickle your fancy, you can use any other vegetable such as peas, broccoli, spinach or even Brussels sprouts.

This is an unbelievably creamy vegan cauliflower sauce, which can be made ahead of time and reheated when needed. It's made easily in your blender. And if you want a nut-free version, use hemp seeds instead of cashews.

Make sure you have nutritional yeast in your cupboard. It gives it that cheesy flavour and makes all the flavours come together.

It offers filling carbs, fibre, protein, vitamins and minerals, but without the heaviness of butter, cream and/or tons of cheese. Does it seem too good to be true? It's not! This cauliflower alfredo pasta recipe is the perfect thing to satisfy that creamy pasta craving without leaving you feeling sluggish.

You may want to double the batch, because it's fabulous the next day too. You can reheat this with a little more oat or almond milk to thin it out if needed. Let's get cooking!

Here's what you're going to need to make this delicious meal at home:

• Medium size cauliflower (approx 450g)
• ⅓ cup Raw Cashews - Soaked for 30 minutes
• 1 Onion - Finely chopped
• 2 fat cloves garlic
• 1 punnet of mushrooms (250g) - you can use any mushrooms for this recipe. I used Swiss brown, but button or portobello work well too
• 1 cup oat milk - or your preferred plant-based milk
• 3 tablespoons nutritional yeast - for that lovely cheesy taste
• 150g wholewhat spaghetti
• Salt and pepper to taste

How to Make Alfredo Sauce with Cauliflower

1. Start by cooking the cauliflower in lightly salted water.
2. Next, fry the onion and garlic until brown, and set aside
3. Sautee or fry the mushrooms in another pan and set aside.
4. In the meantime, bring a large pot of lightly salted water to a boil. Add spaghetti and cook for 8 to 10 minutes or until al dente; drain.
5. Now get a blender or food processor and pop in the cooked cauliflower, fried onion and garlic, cashews, nutritional yeast, and oat milk then season well with salt and pepper.
6. Process until very smooth and creamy. Then taste and adjust the seasoning if needed.
7. Mix the pasta with the mushrooms and the sauce, sprinkle generously with freshly chopped parsley and serve.
