Why You’ll Love This Pasta with Roasted Summer Vegetables

• One-tray roasting: You toss the vegetables on a single baking sheet, meaning there is hardly any mess to clear away after the meal.
• Speedy assembly: While the oven does the heavy lifting, you boil the pasta in about ten minutes, so the whole meal comes together faster than a takeaway delivery.
• Make-ahead friendly: Roast the vegetables up to two days in advance, then simply reheat them with the cooked pasta for a dinner that takes five minutes to finish.
• Kid-approved: My kids absolutely devour this every time I make it, especially when I let them pick which vegetables go on the tray.
• Flexible for busy schedules: You can swap in whatever vegetables are lurking in the fridge drawer, making it a brilliant recipe for using up odds and ends without extra shopping.

Ingredients You’ll Need

• 350g dried pasta (penne, fusilli, or rigatoni work well)
• 2 medium courgettes, cut into 2cm chunks
• 1 large red bell pepper, deseeded and sliced into strips
• 1 large yellow bell pepper, deseeded and sliced into strips
• 250g cherry tomatoes, halved
• 1 red onion, cut into wedges
• 3 cloves garlic, skin on and lightly crushed
• 4 tablespoons olive oil
• 1 teaspoon dried oregano
• ½ teaspoon salt
• ¼ teaspoon black pepper
• 50g grated Parmesan cheese (or vegetarian alternative)
• Small handful fresh basil leaves, torn
• Optional: 2 tablespoons pine nuts, toasted

Tip: For a more filling meal, add 200g of cooked chicken breast or halloumi chunks to the tray during the last ten minutes of roasting.

How to Make Pasta with Roasted Summer Vegetables

1. Preheat the oven and prepare the vegetables. Set your oven to 200°C (180°C fan) or gas mark 6. On a large baking tray, combine the courgette chunks, bell pepper strips, cherry tomato halves, red onion wedges, and crushed garlic cloves. Drizzle over the olive oil, then sprinkle with the dried oregano, salt, and black pepper. Use your hands to toss everything together until every piece is lightly coated — you will see the oil glistening on the vegetables.
2. Roast until tender and caramelised. Spread the vegetables in a single, even layer — if they overlap, they will steam rather than roast. Slide the tray into the oven and roast for 20 to 25 minutes. Halfway through, give the tray a good shake so the vegetables colour evenly. You will know they are ready when the courgettes are golden at the edges, the tomatoes have begun to collapse and release their juices, and the onion wedges are soft and lightly charred. The garlic cloves should feel soft when gently pressed.
3. Cook the pasta while the vegetables roast. Fill a large saucepan with water, bring it to a rolling boil, and add a generous pinch of salt. Tip in the pasta and cook according to the package instructions until al dente — usually about 10 to 12 minutes. The pasta should be firm to the bite but not chalky in the centre. Just before draining, scoop out a mugful of the starchy pasta water and set it aside.
4. Combine the roasted vegetables and pasta. Drain the pasta in a colander, then return it to the empty saucepan. Remove the roasted garlic cloves from the tray — they will be soft and fragrant — and squeeze the creamy garlic paste from the skins directly into the pasta. Add the roasted vegetables and any juices from the tray, then toss everything together gently. The tomatoes will break down slightly, creating a light sauce that clings to the pasta.
5. Adjust the consistency and finish. If the mixture looks a little dry, pour in a splash of the reserved pasta water and toss again. The starch in the water helps the sauce cling to the pasta without becoming watery. Sprinkle the grated Parmesan over the top and stir through until it melts into the vegetables. The final texture should be glossy and moist, not sticky or clumpy.
6. Serve immediately with fresh basil. Divide the pasta among bowls, scatter the torn basil leaves over each portion, and finish with a twist of black pepper. If you are using the pine nuts, sprinkle them on top for a subtle crunch. The dish is best eaten straight away, while the vegetables are still warm and the cheese is gooey.

Tips From My Kitchen

• Cut vegetables to a uniform size: When you chop the courgettes, peppers, and onion into similar-sized pieces, they all finish roasting at the same moment. If some chunks are much larger than others, you will end up with burnt edges on the small pieces and raw centres on the large ones. Aim for 2cm chunks or strips that are roughly the same thickness.
• Use a heavy-duty baking tray: A thin, flimsy tray can cause the vegetables to burn on the bottom before they are properly cooked through. A good-quality, heavy baking sheet distributes heat more evenly, giving you soft, caramelised vegetables without scorching. If your tray looks warped, it is time to replace it.
• Reserve more pasta water than you think you need: The starchy water is a secret weapon for bringing the dish together. I always save at least a full mug, even if I only use a few tablespoons. If the pasta sits for a few minutes before serving, it can absorb moisture and become dry, and having extra water on hand lets you revive it instantly without adding oil.
• Roast the garlic with the skin on: Keeping the cloves in their papery skins protects them from the direct heat, so they steam inside and become sweet and creamy rather than bitter and burnt. Once they are soft, squeezing out the paste is easy, and you avoid the messy job of peeling raw garlic.
• Make the vegetables ahead for busy evenings: Roast a double batch of vegetables on Sunday evening, let them cool completely, and store them in an airtight container in the fridge for up to three days. When you need a quick dinner, simply cook fresh pasta and reheat the vegetables in a frying pan or microwave for two minutes. The flavours actually deepen overnight, so the second meal often tastes even better than the first.
• Do not skip the resting time after tossing: Once you combine the pasta with the roasted vegetables and cheese, let it sit in the saucepan for about one minute before serving. This brief rest allows the starch from the pasta and the cheese to meld with the vegetable juices, creating a cohesive sauce rather than a separated mess. You will notice the texture become silkier after that short pause.

Common Mistakes to Avoid

• Overcrowding the pan: Piling too many vegetables onto the tray traps steam, which makes them soggy instead of caramelised. Use the largest baking sheet you own, and if necessary, split the vegetables between two trays. They should sit in a single layer with a little space between each piece — you want to hear a gentle sizzle, not see a cloud of steam.
• Wrong temperature: Roasting at a temperature lower than 200°C will cause the vegetables to release their moisture before they brown, resulting in a watery, pale finish. Conversely, an oven that runs too hot will char the outside while leaving the inside raw. If your oven runs hot, reduce the temperature by 10°C and check the vegetables five minutes early.
• Skipping the rest time: Serving the pasta immediately after tossing can leave you with a dish where the sauce pools at the bottom of the bowl rather than coating the pasta. Letting it rest for one minute allows the starches to absorb the liquid and the cheese to melt evenly. This small pause makes a noticeable difference to the final texture.

Delicious Variations to Try

• Spicy Version: Add ½ teaspoon of dried chilli flakes to the vegetables before roasting, or stir in a finely chopped fresh red chilli along with the garlic. The heat cuts through the sweetness of the roasted peppers and tomatoes beautifully.
• Vegetarian/Vegan Option: Swap the Parmesan for a vegan hard cheese alternative or a tablespoon of nutritional yeast stirred in at the end. For extra protein, toss in a can of drained chickpeas with the vegetables during the last ten minutes of roasting.
• Different Protein: Replace the chicken with 200g of cooked prawns added to the pasta in the final step — they only need a minute to warm through. Alternatively, cube 250g of halloumi and roast it alongside the vegetables for the last twelve minutes; it turns golden and squeaky on the outside while staying soft within.

What to Serve With Pasta with Roasted Summer Vegetables

• A simple green salad dressed with lemon juice and extra virgin olive oil
• Warm crusty bread or garlic bread to mop up any juices left in the bowl
• A side of steamed green beans or asparagus, tossed with a little butter

Notes

For a vegetarian version, use a vegetarian alternative to Parmesan. Toasting the pine nuts in a dry pan over medium heat for 2-3 minutes enhances their flavor. Reserve extra pasta water to adjust consistency if needed.
