  • 1/2 loaf stale baguette, torn into pieces
  • 4 cloves garlic, peeled and divided
  • 1 medium cauliflower, florets and stalk chopped small and outer green leaves separated and kept whole. (Discard the hard core at the bottom of the outer leaves)
  • 1 tbsp grapeseed or extra virgin olive oil, divided
  • 1 tsp dried parsley
  • 1 medium yellow onion, roughly chopped
  • 2 cups unsweetened plain soy milk
  • 2 tbsp nutritional yeast
  • 1/2 tsp ground mustard
  • 1/4 tsp ground nutmeg
  • 8 oz spaghetti
  • 1 cup vegan cheddar shreds
  • 1/2 tsp kosher salt
  • 1/2 tsp black pepper


  • Make the breadcrumbs and boil a large pot of water for the pasta. Heat ½ tablespoon of oil in a large non-stick frying pan on medium heat. Combine the torn bread, 2 garlic cloves, outer green cauliflower leaves and remaining ½ tablespoon oil in a food processor and process until fine crumbs form. Add to the pan and cook, stirring frequently, until golden brown, 10-15 minutes. Transfer to a bowl and set aside.
  • Return the pan to the heat and add the 2 remaining garlic cloves, onion, cauliflower florets and stalk, milk, nutritional yeast, ground mustard and nutmeg. Raise the temperature to medium-high and bring to just under a boil, then reduce heat to medium, cover and simmer until soft, about 10 minutes. While this is cooking, add the pasta to the boiling pot of water.
  • Gently pour the vegetables and milk into the food processor, add the cheese and blitz until smooth. Return to the pan and scoop out the pasta directly from the pot into the pan, including 1-2 ladles of starchy pasta water. Toss to combine. Season with salt and pepper. Serve with a generous topping of breadcrumbs.
