The star of this recipe is undoubtedly broccoli. The humble green vegetable that doesn't get enough focus on it and which is often forgotten. But, we'd all benefit from getting broccoli into our diet more often. Including nutrient rich vegetables like this into your diet is mega important.

This creamy pasta sauce is centred around broccoli. Broccoli may be one of your five a day but it's not exactly creamy. To get the creamy texture we take cooked broccoli and blitz it with soaked cashews, water and a range of seasonings. This creates a luscious, bright green, creamy pasta sauce that just so happens to be vegan!

Serve it with your favourite pasta shape (and maybe even some garlic tear and share bread) and you've got a simple but nutritious meal you can whip up in no time.

  • Nutritional yeast
  • Lemon
  • Garlic
  • Parsley

Hint: cook the pasta in the same pan as the broccoli to save water!

Substitutions

With a recipe this simple there aren't many swaps possible but if you are in a pinch you can try one of these:

  • Garlic: swap fresh garlic for lazy garlic or garlic powder
  • Nutritional yeast: for a cheesy flavour replace nutritional yeast with vegan cheese
  • Parsley: swap fresh parsley for dried parsley

Variations

This method works well for turning lots of different vegetables into pasta sauce so get experimenting! I've also used this technique to make a creamy carrot pasta sauce.

For some added protein why not add cooked tofu, tempeh or vegan chicken pieces to the sauce?

Equipment

Get the following kitchen equipment ready before you begin cooking:

  • Chopping board
  • Knife
  • Citrus juicer
  • 2 saucepans
  • High speed blender

Storage

This sauce is best enjoyed fresh so you won't be able to keep any leftovers or make it in advance.

Frequently asked questions

Do you have to soak / boil the cashews?

Yes, this gives them the right consistency so that when they are blended they help the sauce become creamy. If you skip this step you will have chunks of hard nut in your sauce.

Can I use an immersion blender to make this recipe?

Yes, though you may find it takes longer to get the desired consistency.

Can I save back some of the broccoli to add some texture to the dish?

Yes, absolutely! I like to think of this as a "hidden" vegetable sauce but if you want the added texture then do keep some broccoli to one side and add to the sauce after its been blended.

Top tip

The smaller you cut your broccoli florets, the sooner you can have this dish on the table! Don't try boiling the head whole!
