How to make this Vegan Pesto Pasta

Scroll down to the bottom of the post for the full recipe.

  • Place all the ingredients for the pesto in a food processor.

Substitutions you can make to this recipe:

  • you can substitute the pine nuts with any nuts or seeds: sunflower seeds, pumpkin seeds, almonds, macadamia nuts, walnuts, cashews etc
  • for an oil-free version, you can substitute the olive oil with water or any plant-based milk.

Ingredients you can add to the recipe:

  • I like to add frozen green peas to this and cook them at the same time as the pasta, but you can add any other vegetables you like. Broccoli or kale can be cooked with the pasta,  spinach can be wilted in at the end. Or you could add some pan-fried sliced courgette (zucchini) or mushrooms.
  • Coconut bacon or almond bacon!
  • Chickpeas or white beans
  • Tinned sweetcorn
  • Olives.

How to make Creamy Vegan Pesto Pasta

If you want to make this Vegan Pesto Pasta creamy, you can do this very easily using plant-based milk (I like unsweetened almond milk, unsweetened cashew milk or unsweetened oat milk for this) and cornflour (cornstarch).

For the serving size specified in this recipe, you'll need to use 230 ml (1 cup) plant-based milk and 2 tablespoons cornflour (cornstarch).

Be very careful with how you use the cornflour, though! You have to dissolve the cornflour first in a very small amount of cold water and then only add it to the sauce once it's very hot and bubbling. If you add the cornflour straight to the hot sauce without dissolving it in cold water first, it'll form small clumps that refuse to dissolve and if you add the dissolved cornflour when the sauce isn't very hot, the same thing will happen.

Troubleshooting tip: However, if you do end up with a sauce full of clumps of cornflour, you can just tip the sauce back into the blender you made your pesto in until you get rid of the lumps and then reheat the sauce in the pan, gently stirring it, and it should thicken up.
