Ingredients You’ll Need

• 350g dried rotini pasta
• 2 medium red bell peppers, deseeded and cut into 3cm chunks
• 2 medium yellow bell peppers, deseeded and cut into 3cm chunks
• 1 large red onion, peeled and cut into 2cm wedges
• 2 medium courgettes, halved lengthways and sliced into 1.5cm half-moons
• 250g cherry tomatoes, left whole
• 4 cloves of garlic, skin on, lightly smashed
• 60ml extra virgin olive oil, plus extra for drizzling
• 1 teaspoon fine sea salt
• ½ teaspoon freshly ground black pepper
• 2 tablespoons balsamic vinegar
• 1 teaspoon Dijon mustard
• 60g pine nuts
• 50g freshly grated Parmesan cheese (or a vegetarian hard cheese alternative)
• A generous handful of fresh basil leaves, torn just before serving

Tip: For the best roasted flavour, ensure your vegetables are cut into uniform pieces so they cook at the same rate. Don’t overcrowd the baking tray; if the vegetables are too close together, they’ll steam rather than roast. Use two trays if necessary.

Equipment You’ll Need

• Large pot for boiling pasta
• Colander
• Two large baking trays
• Baking paper or a silicone mat
• Large frying pan (for toasting pine nuts)
• Large mixing bowl
• Small bowl or jar for the dressing
• Sharp knife and chopping board

How to Make Roasted Veggie and Rotini Pasta Salad

1. Preheat and Prepare: Preheat your oven to 200°C (180°C fan). Line two large baking trays with baking paper. This initial step sets the stage for the entire dish; the heat will begin to build, and you’ll soon smell the promise of a cosy kitchen.
2. Roast the Vegetables: In a large bowl, toss the bell peppers, red onion, courgettes, cherry tomatoes, and smashed garlic cloves with 60ml of olive oil, salt, and pepper. Spread the vegetables in a single layer on the prepared trays. You should hear a gentle sizzle as they hit the hot trays. Roast for 30-35 minutes, giving the trays a good shake halfway through, until the peppers are tender and their edges have begun to char, the courgettes are golden, and the tomatoes have blistered and collapsed slightly. The kitchen will smell sweet and deeply savoury.
3. Toast the Pine Nuts: While the vegetables are roasting, place a large frying pan over a medium heat. Add the pine nuts and toast them, shaking the pan frequently, for 2-3 minutes. You’re listening for a very faint rustling sound and watching for them to turn a light golden brown. They can burn in seconds, so keep a close eye on them. Once toasted, tip them onto a plate to cool.
4. Cook the Pasta: Bring a large pot of generously salted water to a rolling boil. Add the rotini and cook according to the package instructions until al dente — the pasta should have a tiny white dot in the centre when you bite into it, offering a pleasing resistance. Just before draining, reserve about 120ml of the starchy pasta water. Drain the pasta in a colander and let it steam dry for a minute or two.
5. Make the Dressing: In a small bowl or a jam jar, whisk together the balsamic vinegar, Dijon mustard, and a pinch of salt and pepper. Slowly drizzle in 3 tablespoons of extra virgin olive oil while whisking continuously until the dressing is emulsified and looks smooth and glossy.
6. Combine While Warm: Transfer the drained pasta to a very large mixing bowl. Using tongs, immediately add the roasted vegetables, squeezing the softened garlic cloves out of their skins and into the bowl first — they will be soft and buttery. Pour over the dressing and add about 60ml of the reserved pasta water. Toss everything together vigorously. The warm pasta will absorb the dressing and the starchy water will help it cling to every spiral, creating a silky, cohesive texture.
7. Finish and Serve: Allow the salad to cool for at least 10 minutes at room temperature. After testing this recipe five times, I finally got it just right: the salad should be served warm or at room temperature, not piping hot. Stir through the toasted pine nuts, the grated Parmesan, and most of the torn basil leaves. Taste and adjust seasoning. Transfer to a serving platter and garnish with the remaining basil. The finished dish should be a beautiful mosaic of colour, with glossy pasta, tender vegetables, and pops of green from the basil.

Tips From My Kitchen

• Don’t Skip the Pasta Water: This is my number one tip for any pasta salad. The starchy water acts as a natural emulsifier, helping the olive oil and vinegar-based dressing cling to the pasta rather than pooling at the bottom of the bowl. It also seasons the dish from within. Add it a little at a time until the salad looks glossy and well-coated.
• Roast at a High Temperature: 200°C is not an arbitrary number. This high heat is essential for caramelising the vegetables’ natural sugars and creating that desirable char without turning them to mush. A lower temperature would result in soft, watery vegetables that would make the salad soggy.
• Under-Cook the Pasta Slightly: Because the pasta will continue to absorb liquid from the dressing and the vegetables as it sits, it’s wise to cook it a full minute less than the packet suggests. An al dente texture in the pot will result in a perfectly tender salad later, preventing it from becoming a mushy mess.
• Use a Generous Hand with Salt: Season each component individually. Salt the pasta water until it tastes like the sea. Season the vegetables before they go into the oven. A final pinch of flaky sea salt just before serving brightens the entire dish. Under-seasoning is the most common mistake with pasta salads.
• Let It Rest: This salad is a tale of two temperatures. It is at its most aromatic and comforting when served warm, about 15-20 minutes after assembling. However, if you have the patience, let it sit in the fridge for an hour or even overnight. The flavours marry beautifully, and it becomes a wonderfully robust cold salad for packed lunches.

Delicious Variations to Try

• Spicy Version: To introduce some heat, add ½ teaspoon of dried chilli flakes to the vegetables before roasting. You can also stir a finely chopped fresh red chilli into the finished salad for a vibrant, fiery kick that contrasts nicely with the sweet roasted peppers.
• Vegetarian/Vegan Option: To make this completely vegan, simply omit the Parmesan cheese. For a savoury, umami boost instead, stir through 2 tablespoons of nutritional yeast flakes along with the dressing. The toasted pine nuts and roasted vegetables provide plenty of texture and richness on their own.
• Different Protein: If you’d like to add more substance, cube 200g of halloumi and pan-fry it until golden and crisp on each side, then toss it through the salad just before serving. Alternatively, leftover shredded roast chicken or some flaked, grilled mackerel works beautifully, adding a smoky, savoury depth that complements the roasted vegetables.

What to Serve With Roasted Veggie and Rotini Pasta Salad

• A simple, crisp green salad with a sharp lemon vinaigrette to cut through the richness.
• Grilled chicken or fish, like the Grilled Chicken Pasta Salad Easy, for a more substantial meal.
• Some crusty, warm sourdough bread to mop up any leftover dressing from the bowl.
• A side of marinated olives and artichoke hearts for a Mediterranean-inspired spread.
