This vibrant romesco pasta salad is a sophisticated take on a high-protein vegetarian meal. Drawing inspiration from the classic Spanish sauce, the dressing is made by blending sweet roasted red peppers with toasted walnuts and garlic for a rich, savoury finish. The use of large spiral pasta ensures every nook is filled with the silky sauce, while fresh ripe tomatoes and fragrant basil keep the dish feeling light and seasonal.
Providing a satisfying crunch, a golden breadcrumb and lemon zest topping is added just before serving. This dish is an excellent choice for a nutritious lunch or a substantial dinner, offering a balance of healthy fats and plant-based protein. It travels well, making it ideal for a luxury picnic or a prepared weekday meal that doesn't compromise on flavour.

Zest and juice of 1 lemon
2 garlic cloves
1 teaspoon crushed red pepper flakes, divided
120ml plus 2 tablespoons extra-virgin olive oil
Kosher salt
450g fusilli giganti (large spiral-shaped pasta) or medium shell pasta

How to make Romesco Pasta Salad with Basil and Parmesan
Back to contentsPreheat oven to 177°C. Toast walnuts on a rimmed baking sheet, tossing halfway through, until golden brown, 10–12 minutes. Let cool.
Meanwhile, process bread in long pulses in a food processor until coarse crumbs form (you should have about 240ml ). Transfer to a small bowl.
Purée roasted red peppers, lemon juice, garlic, 1/2 teaspoons red pepper flakes, and about one-quarter of the cooled walnuts in food processor (no need to clean) until smooth. With the motor running, very gradually stream in 120ml oil. Process until thick; season romesco dressing generously with salt.
Cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente. Drain and rinse under cold water (this stops cooking and removes surface starch so the pasta will be less gummy). Shake off excess water and transfer to a large bowl. Toss pasta with half of the romesco to coat; set aside. Finely chop remaining walnuts; set aside.
Heat remaining 2 tablespoons oil in a medium saucepan over medium and cook breadcrumbs, lemon zest, and remaining 1/2 teaspoons red pepper flakes, stirring often, until breadcrumbs are golden, 5–7 minutes. Remove from heat.
Toss reserved pasta with remaining dressing, then fold in tomatoes, Parmesan, and reserved walnuts just to distribute. Sprinkle breadcrumb mixture over pasta and top with basil.
