Roasted Courgette and Aubergine Salad with Lemon Dressing

Top Top Tips for the Best Roasted Courgette and Aubergine Salad

• Slice the vegetables very thin. This is the single biggest factor in how the salad turns out. Cut the courgette into very thin rounds and the aubergine into thin quarters, ideally under 2 mm thick, almost like crisps. Thin slices roast quickly, lose their water fast and crisp up at the edges instead of going soft and watery in the middle. Thick slices steam in their own moisture and stay pale and floppy, which is the most common reason this kind of salad disappoints. A sharp knife or a mandoline makes the job quick and keeps every piece even.
• Don't line the tray. It's tempting to reach for foil or baking paper for an easy clean-up, but direct contact with the hot metal tray is what gives the vegetables their golden brown, caramelised edges. A lined tray traps moisture underneath and steams the vegetables instead of roasting them, leaving them pale and limp. A good non-stick or well-seasoned tray will release the veg easily once they have browned. If you are worried about sticking, simply use a little more olive oil and let the pieces sit until they release on their own.
• Give the vegetables room to breathe. Crowding the tray is the second most common reason roasted vegetables turn out soggy rather than crisp. Spread the courgette and aubergine in a single layer with a little space between each piece. If your tray is too small, use two trays and swap their positions halfway through, rather than piling everything on. The vegetables give off steam as they cook, and that steam needs space to escape, otherwise it pools around them and softens the edges you are trying to crisp.
• Stir the vegetables twice during roasting. Halfway markers matter here, so give the tray a stir at least twice while the vegetables cook. The pieces touching the metal brown first, so turning them moves the pale, untouched slices down into contact with the hot tray and brings the browned ones up. Without stirring, you end up with some pieces dark and others still raw and soft. A quick toss with a spatula every five to seven minutes keeps the courgette and aubergine roasting evenly and gives you that consistent golden colour across the whole tray.
• Let the roasted vegetables cool before dressing. Take the tray out and let the vegetables sit for a few minutes so they are warm rather than piping hot when they meet the dressing. Vegetables that are too hot can wilt the basil instantly and make the raw tomatoes go soft and mushy in the bowl. Warm is the sweet spot: hot enough to soak up the lemon dressing, but cool enough to keep the fresh elements looking and tasting fresh. This short rest also lets any excess steam escape so the salad doesn't turn watery.
• Zest the lemon before you juice it. It's far easier to run a grater over a whole, firm lemon than over a squeezed, floppy one, so always take the zest first. The zest holds the fragrant citrus oils that give the dressing its bright, perfumed lift, and you'd lose a lot of that aroma if you skipped it. Use only the yellow outer layer and avoid the white pith underneath, which is bitter. A microplane or fine grater gives you the lightest, fluffiest zest with the most flavour.
• Let the dressing rest for ten minutes before using it. The dressing only takes a couple of minutes to whisk, but a short rest transforms it. Standing time softens the raw garlic so it no longer tastes harsh, lets the chilli flakes bleed their warmth through the oil, and gives the lemon and sugar a chance to settle into balance. Give it a final whisk just before pouring, as the oil and lemon juice naturally separate as they sit. A rested dressing tastes mellow and complete; a freshly mixed one can taste raw and a little aggressive.
• Choose ripe but firm tomatoes. The tomatoes add juiciness and freshness, but overripe ones collapse and make the salad watery, while underripe ones taste flat and hard. Look for tomatoes that have a little give when pressed but still hold their shape when cut into wedges. Vine or beef tomatoes work especially well here because they're meaty and full of flavour. If your tomatoes are very juicy, you may want to drain off some of the liquid before adding the dressing.
• Add the feta in larger crumbles, not a fine grate. Breaking the feta into rough, chunky pieces by hand gives you pockets of creamy, salty cheese throughout the salad. If you grate or crumble it too finely, it disappears into the dressing and you lose that lovely contrast in texture. Larger crumbles also look more generous and rustic on the plate. Add them right at the end so they stay intact and don't turn to paste when you mix.
