Roasted courgettes with parmesan, a crunchy breadcrumb topping and bright lemon zest — ready in under 10 minutes, made with simple pantry ingredients and a proper crispy edge. This easy roasted courgette recipe is the kind of side dish that wins over even people who say they don't really like courgettes.
I've fiddled with this one for a while to get it right, and I'm happy to share what works. The trick with good roasted courgettes is honestly quite simple — soak the spears in salted water first, pat them properly dry, then roast hot and fast. Most courgette recipes leave you with soggy, sad pieces swimming in their own water, but this method gives you golden-edged, tender spears topped with a parmesan crust that crackles when you bite in.
The flavour sits on the lighter, herby side with thyme, oregano and garlic powder, finished off with a fresh hit of lemon zest right at the end. It's a budget-friendly side that pairs with almost anything — grilled chicken, pasta, baked fish, or simply eaten straight from the tray. If you've tried roasted courgettes before and been let down by limp results, this one will change your mind.

Ingredients for Crispy Roasted Courgettes
Here's what goes into this roasted courgette recipe and why each part is here.
- Green courgettes – Pick firm, medium-sized ones with smooth, glossy skin. Smaller courgettes have less water and roast better than the giant ones.
- Garlic powder – gives a deep, mellow garlic flavour that doesn't burn the way fresh garlic does at high heat.
- Dried thyme – earthy and slightly woody, it sits beautifully against the cheese and lemon.
- Dried oregano – a Mediterranean note that lifts the whole dish without taking over.
- Freshly grated parmesan – melts into a proper savoury crust. Pre-grated parmesan won't crisp up the same way, so grate your own.
- Breadcrumbs – the secret to that golden, crackly topping. Panko works brilliantly if you have it.
- Lemon zest – the brightness that pulls everything together. Added at the end so the oils stay fragrant.
- High smoke point oil – avocado, grapeseed, sunflower or regular olive oil all work.
- Sea salt – a small pinch lifts the flavour without making things too salty, especially with parmesan already in the mix.
- Cold water for soaking – the quiet hero that removes bitterness and pulls out excess moisture.
How to Roast Courgettes – 4 Easy Steps
Making roasted courgettes is genuinely quick once you know the order. Here's the method.
This recipe works for oven and air fryer, instructions would be the same. I cook using airfryer function "Roast" at 200°C (400°F). Arrange spears skin side down and make them feel comfortable - do not overcrowd, leave some gaps between the courgettes.
- Step 1: Cut each courgette in half lengthwise, then slice each half into 8 long spears. Drop them into a bowl of cold, lightly salted water and leave to soak for 20–30 minutes. This step pulls out any bitterness and helps the spears roast without going soggy.
- Step 2: Drain the spears and pat them properly dry with a clean tea towel or kitchen paper. Toss them with the oil, garlic powder, oregano and thyme until each spear has a light, even coating.
- Step 3: Arrange the spears skin-side down on a baking tray or air fryer mat, leaving a little space between each one. Roast at 200°C (400°F) for 10 minutes.
- Step 4: While they roast, mix the parmesan, lemon zest and breadcrumbs in a small bowl. Pull the tray out, sprinkle the topping evenly over the spears, and return to the oven for 1-2 more minute (3-4 minutes for oven), just until the cheese melts and the breadcrumbs turn golden.
How to Serve and Store Roasted Courgettes
Serve these roasted courgettes straight from the oven for the best texture — the parmesan crust softens as it cools, so timing matters. They go beautifully alongside grilled chicken, baked salmon, lamb chops, or a simple bowl of pasta with garlic butter. I also love them as a light lunch with a poached egg on top and a slice of sourdough on the side. If you're serving guests, scatter a few fresh coriander or parsley leaves on top and add a wedge of lemon for squeezing.
Leftovers will keep in an airtight container in the fridge for up to 2 days, but I'll be honest — the crispy topping doesn't survive storage that well. To reheat, pop them back into a hot oven or air fryer at 180°C for 3–4 minutes rather than the microwave, which turns them soft. Roasted courgettes don't freeze well because of the water content, so this is a recipe best made fresh and eaten the same day.

Top Tips and Notes for the Best Roasted Courgettes
- Don't skip the salt water soak. Soaking the courgette spears in cold salted water for 20–30 minutes pulls out bitterness and draws excess moisture from the flesh. This is the single biggest thing that separates good roasted courgettes from a watery, soggy mess. The salt also seasons the spears from the inside, so you need less salt on top later. If you're really short on time, even a 10-minute soak helps.
- Pat the spears properly dry. After draining, take a clean tea towel or some kitchen paper and press gently on every side of every spear. Wet courgettes will steam in the oven rather than roast, and steaming is the enemy of crispy edges. This single minute of effort makes a noticeable difference to the final texture. Don't rush this step.
- Pick the right oil. Use a high smoke point oil — avocado, grapeseed, sunflower or regular olive oil all work well. Extra virgin olive oil can turn bitter and smoky at 200°C, which is the temperature this recipe runs at. The oil's job here is to carry the heat and help the spices stick, not to flavour the dish. Save your good extra virgin for drizzling at the end if you fancy.
- Choose smaller courgettes when you can. Smaller, firmer courgettes have less water and a denser texture, which means they roast better and don't go limp. Giant supermarket courgettes are often watery and seedy inside. If you can only find large ones, scoop out the seedy middle with a teaspoon before slicing into spears. Look for smooth, unblemished skin and a slight weight in your hand.
- Add the lemon zest right at the end. Lemon zest contains volatile oils that fade fast under high heat, so I add it mixed with the cheese for the final minute of roasting only. If you zest it earlier and roast it for the full 8 minutes, you lose most of the fragrance. For an even brighter finish, save a small pinch of raw zest and scatter it over the spears just before serving. That extra zing makes a real difference.
- Use the air fryer if you have one. The air fryer version of this recipe works just as well as the oven — same temperature, same timing. The circulating hot air actually crisps the parmesan topping a touch faster, and clean-up is easier. Use a perforated air fryer mat or basket and don't overcrowd it. If your air fryer is small, do two batches rather than piling spears on top of each other.
- Don't crowd the tray. Give each spear a little breathing room on the tray so hot air can circulate around it. When courgettes are packed too tightly, they trap steam and end up soft instead of golden. Use two trays if you need to. This is especially important if you're doubling the recipe for a bigger crowd — better to spread out properly than rush.
- Serve immediately for best results. The crispiest moment for any roasted courgette recipe is the first 10 minutes out of the oven. The parmesan crust hardens as it cools, but the contrast of crunchy topping and tender flesh is at its peak fresh from the tray. If you need to hold them briefly, leave them on the hot tray rather than transferring to a cool plate. Plate up at the very last minute.
Frequently Asked Questions
How do I stop roasted courgettes from going soggy?
Soggy courgettes happen for two reasons — too much water in the vegetable and not enough heat. Soak your spears in salted cold water first to draw out moisture, then pat them very dry before roasting. Roast at a high temperature (200°C / 400°F) on a single, uncrowded layer to let steam escape rather than build up around the spears.
Can I use yellow courgettes or marrows instead?
Yes, yellow courgettes work perfectly with this method — they have the same texture as green ones, just a milder, slightly sweeter flavour. Avoid marrows, though, because they're much wetter and seedier, and they tend to collapse under high heat. If marrows are all you've got, scoop out the seedy core first and accept a softer final texture.
What's the difference between courgettes and zucchini?
They're the exact same vegetable — courgette is the British and Irish name, zucchini is the American and Australian name. The word courgette comes from French, while zucchini comes from Italian. So if you find an American recipe calling for zucchini, you can use British courgettes one-for-one without changing a thing.
How do I remove bitterness from courgettes?
Soaking sliced courgettes in salted cold water for 20–30 minutes draws out the bitter compounds and excess moisture in one go. Older or larger courgettes tend to be more bitter, so this step matters more with those. For very bitter courgettes, you can also sprinkle the cut spears with salt, leave them for 15 minutes, then rinse and pat dry before tossing with oil.
Do I need to peel the courgettes first?
No, don't peel them — the skin holds the spears together during roasting and gives you those lovely vibrant green edges. The peel is also where most of the fibre and nutrients live. Just give the courgettes a good wash under cold water and trim the ends before cutting into spears.
