OK but not wonderful. I used wholewheat spaghetti and threw in some shredded basil because I needed to use it up. Might make again but probably won't.

1011 calories? Can this actually be right?

I know this comment is really old, but in case anyone sees it and was wondering- 1 red pepper = 25. 30ml olive oil = 247. 50g walnuts = 327. 1 small garlic clove = 5. 100g linguine or spaghetti = 371. parmesan= no amount given, but if we say 30g that's 121 calories. Total = 1096. So yes, the count is accurate if you eat all the pesto. Similar recipes with lower counts are probably meant to serve two or more people, whereas this is a one-portion recipe.

that's what i thought as soon as i saw how high the calorie count was. I've just found a similar recipe without the parmesan but with 2 tbsp of cream and some capers and it was only 250 calories.

What would a good alternative to the walnuts be as I am allergic?

Thanks for your question, you could swap with another nut such as (unsalted) cashews. Take a look at the following alternative recipe:

I must admit I didn't think the end result justified the 1000 calorie ticket so I doubled the pasta, fried up about 15 mushrooms, 10 halved cherry tomatoes in a tiny bit oil over a high heat to sear them. Then added some chopped roasted red peppers and the walnut mixture let that sizzle a bit. Then thinned the mixture with some of the pasta water, added 2 big tablespoons of low fat creme creche, seasoned with salt pepper and a few squeezes of lemon juice. Then threw in a couple of handfuls of baby spinach just so it wilts. And finally added the pasta and topped the chopped walnuts. Serves 2-3.
