Ingredients for Red pesto rigatoni
6 oil-packed anchovy fillets
4 garlic cloves, smashed
180 ml extra-virgin olive oil
65 g raw walnuts
45 g double concentrated tomato paste
2 red Fresno chiles, halved lengthwise, deseeded
85 g Parmesan, finely grated
45 ml fresh lemon juice
2.5 g kosher salt, plus more
450 g rigatoni
30 g unsalted butter, cut into pieces
How to make Red pesto rigatoni
Heat a small saucepan over medium heat and add the anchovies, garlic, oil, and walnuts. Cook, stirring often, for about 5 minutes, or until the walnuts are deep golden and the garlic is just turning golden.
Stir in the tomato paste and cook for a further 2 minutes, or until it darkens slightly. Remove from the heat and allow to cool for 5 minutes.
Scrape the walnut mixture, including the oil, into a food processor. Add the chiles, Parmesan, lemon juice, and ½ tsp salt. Pulse until a thick paste forms. Transfer the pesto into a large bowl.
Meanwhile, bring a large pot of salted water to the boil. Add the pasta and cook, stirring occasionally, until al dente. Drain the pasta, reserving 375 ml of the cooking liquid.
Add the butter to the pesto, followed by the drained pasta and 125 ml of the reserved pasta cooking liquid. Using tongs, toss vigorously, adding more cooking liquid as needed, until the pasta is glossy and well coated with the sauce. Taste and adjust seasoning with more salt if necessary.
Do Ahead: The pesto can be made up to 5 days in advance. Cover and chill until needed.
