  1. Cook the pasta following pack instructions. Meanwhile, toast the walnuts in a dry pan for a few mins. Add half the walnuts to the small bowl of a food processor or a hand chopper, along with the red peppers, Parmesan, garlic, basil, oil and some seasoning. Whizz to a paste, adding a splash of water from the pasta if it is a little dry.

  2. Drain the pasta, reserving a cup of the cooking water. Return the pasta to the pan and set over a low heat. Add the pesto, mascarpone and 3-4 tbsp of the reserved pasta water, then stir until the mascarpone has melted, adding a splash more pasta water if the sauce needs thinning. To serve, crush the remaining walnuts in your hand and scatter over the pasta with a few more basil leaves and some extra Parmesan.

Love this recipe! I wasn't sure if the recipe asked for homemade grilled peppers or peppers from a jar. I used peppers from a jar but I also grilled a fresh pepper myself and added that desperately to the dish. I also switched out some of the walnuts for scattering for toasted pine nuts. Great recipe easy and very tasty!

hahaha autocorrect fail i added the pepper separately not desperately. I mean peppers are great but not that great ;-)

Really tasty and easy to make. Leftovers were great cold for lunch the next day!

I liked the sound of this but wanted a healthier version so tried this without mascarpone and balanced the strong, bitter walnut taste with an extra red pepper but it still came out too nutty for my liking. Sort of eating pasta with walnut butter. I may try this again using fresh cream or fromage frais instead and hope it turns out better.

Doubled this to feed a crowd. Easy and delicious, everyone loved it. Leftovers made great pasta salad lunches for the week.

How much basil, exactly, is in "large pack" basil? When I checked the "Buy Ingredients" list, each supermarket had a different size. Suppose one wants to use fresh basil, instead of buying it in a plastic bag at the supermarket? Please give the weight - and not the package size.

Hi there. For a large pack use approximately 20g of fresh basil.
