Make it gluten-free

Replace the spaghetti with gluten-free spaghetti, and make sure the pesto is a gluten-free variety. 


  1. Cook the spaghetti following pack instructions. Meanwhile, boil the kettle, put the spinach and peas in a bowl, and cover with boiling water. Leave for about 3 mins until the peas are tender, then drain well. Tip the veg into a food processor or blender, add the basil, pesto, cream and Parmesan, and whizz to make a smooth sauce.

  2. Drain the pasta, reserving a little of the cooking water, and return to the pan. Pour over the sauce and return to a low heat to cook for a few mins, until the sauce clings to the spaghetti. Add a little pasta water if it looks too dry, season to taste and serve with extra Parmesan and scattered with basil leaves, if you like.
