Why You’ll Love This Roasted Veggie and Rotini Pasta Salad
- One-pan veggie roasting: You toss everything onto a single baking tray, so there are fewer dishes to wash at the end of a long day.
- Make-ahead magic: This dish tastes even better the next day, meaning you can prep it on Sunday and have dinner sorted for Monday night.
- Budget-friendly ingredients: Everyday vegetables and a box of pasta keep costs low, yet the roasted flavours make it feel like something special.
- Customisable for picky eaters: Swap in whatever veg your family has in the fridge — it’s forgiving and always turns out delicious.
- No last-minute stress: Serve it warm, at room temperature, or straight from the fridge — your choice, zero fuss.
Ingredients You’ll Need
- 300g dried rotini pasta
- 2 medium courgettes, chopped into 2cm chunks
- 1 large red bell pepper, deseeded and diced
- 1 large yellow bell pepper, deseeded and diced
- 1 red onion, cut into wedges
- 250g cherry tomatoes, halved
- 3 tablespoons olive oil
- 2 teaspoons dried oregano
- 1 teaspoon garlic powder
- Salt and freshly ground black pepper, to taste
- 100g feta cheese, crumbled
- 3 tablespoons balsamic vinegar
- Handful of fresh basil leaves, roughly torn
Tip: For the best roasted flavour, cut your vegetables into even-sized chunks so they all cook at the same rate. I’ve been making this for over 8 years, and it never disappoints when the veg are uniform in size.
How to Make Roasted Veggie and Rotini Pasta Salad
- Preheat your oven to 200°C (180°C fan). While it heats, line a large baking tray with baking parchment — this saves scrubbing later. You’ll hear the paper crinkle as you lay it flat.
- Prepare the vegetables. In a large bowl, toss the courgette chunks, diced peppers, red onion wedges, and halved cherry tomatoes with the olive oil, dried oregano, garlic powder, and a good pinch of salt and pepper. Use your hands to coat everything — you’ll feel the oil slick between your fingers, and the aroma of oregano will start to lift.
- Spread the veg onto the tray. Arrange them in a single layer, making sure no pieces overlap. If they’re crowded, they’ll steam instead of roast, and you want that lovely charred smell to fill your kitchen. Roast for 20–25 minutes, giving the tray a shake halfway through. The veg are ready when the edges look dark and slightly crispy, and you can hear them sizzle as they come out of the oven.
- Cook the pasta. While the veg roasts, bring a large pot of salted water to a rolling boil — you’ll see big bubbles breaking the surface. Add the rotini and cook according to package instructions until al dente. About 1 minute before the timer goes off, scoop out a cup of the starchy pasta water and set it aside. Drain the pasta in a colander and give it a quick shake; you’ll see steam rising and the pasta will feel firm but tender when you pinch a piece.
- Combine everything while warm. Tip the drained pasta into a large serving bowl. Add the roasted vegetables straight from the tray, scraping in all the caramelised bits from the parchment. Drizzle over the balsamic vinegar and toss gently with tongs. The colours will be vibrant — deep reds, golden yellows, and charred greens — and the smell of roasted veg mixed with vinegar is absolutely mouthwatering.
- Finish and rest. Sprinkle over the crumbled feta and torn basil. If the salad looks a little dry, add a splash of the reserved pasta water to loosen it. Give everything one final toss. Let the salad rest for at least 10 minutes before serving — this allows the flavours to meld together. After testing this recipe five times, I finally got it just right, and that resting step is the secret.
Tips From My Kitchen
- Don’t skip lining the tray: Baking parchment means you lift the veg off without any stuck-on mess. You can literally throw the paper away and your tray is clean — that’s the kind of shortcut busy weeknights demand.
- Salt the pasta water generously: The water should taste like the sea. This is the only chance to season the pasta from the inside out, and it makes a noticeable difference to the final dish.
- Reserve that pasta water: Even if you think the salad looks moist enough, having a little starchy water on standby helps loosen the dressing without adding extra oil. It’s a trick professional chefs use all the time.
- Roast veg in advance: You can roast the vegetables up to two days ahead and store them in the fridge. When you’re ready to eat, just reheat them gently in a frying pan while the pasta cooks — dinner comes together in under 15 minutes.
- Let the salad come to room temperature: Cold pasta salad can taste dull. Taking the chill off for 15 minutes before serving wakes up the flavours, especially the balsamic and feta.
- Double the batch: This recipe scales beautifully. Make a double portion for lunches throughout the week; it holds up well and the roasted veg only get better as they marinate in the vinegar.
Equipment You’ll Need
- Large pot for boiling (at least 5 litres capacity)
- Colander for draining the pasta
- Large baking tray (approx 30x40cm)
- Baking parchment
- Large mixing bowl
- Tongs or a pasta fork for tossing
- Sharp knife and chopping board
Common Mistakes to Avoid
- Overcrowding the pan: If you pile the vegetables on top of each other, they release steam and turn soggy rather than developing those lovely roasted edges. Always spread them in a single layer — use two trays if you need to.
- Wrong temperature: Roasting at too low a temperature (below 180°C) will slowly dry out the veg without caramelising them. Stick to 200°C (180°C fan) so the sugars brown quickly and the insides stay tender.
- Skipping the rest time: Eating this salad straight away means the flavours haven’t had a chance to mingle. The resting period allows the balsamic to soak into the warm pasta and the feta to soften slightly — it transforms the dish from good to memorable.
What to Serve With Roasted Veggie and Rotini Pasta Salad
- A simple green salad with a lemon vinaigrette adds freshness alongside the rich roasted veg.
- Grilled chicken breasts or lamb koftas make this a heartier meal for bigger appetites.
- Crusty bread to mop up any leftover dressing from the bottom of the bowl — my kids fight over the last bits.
- If you’re after something lighter, try this alongside our Orzo Salad Cucumbers Fresh Dill for a complete meat-free spread.

Frequently Asked Questions
Can I use gluten-free pasta?
Absolutely. Just be sure to cook it slightly less than the package suggests, as gluten-free pasta can turn mushy if boiled too long. The rest of the recipe stays exactly the same.
How long does this keep in the fridge?
Stored in an airtight container, this salad keeps well for up to four days. The pasta will absorb some of the dressing overnight, so you might want to add a splash of balsamic or olive oil when serving leftovers.
Can I add protein to this salad?
Certainly. Grilled chicken, flaked tinned tuna, or even chickpeas work beautifully here. For a vegetarian protein boost, try our No Bake Pasta Salad Chickpeas for inspiration.
Why are my roasted vegetables soggy?
This usually happens when the tray is overcrowded or the oven temperature is too low. Make sure your veg are in a single layer with space between each piece, and always preheat the oven fully before roasting.
Can I freeze this pasta salad?
I don’t recommend freezing it, as the pasta texture changes and the vegetables become watery when thawed. It’s best enjoyed fresh or within a few days from the fridge.
