Your courgette plant will not halt its growth. Right now, in peak summer, a single healthy plant produces a new fruit every 2 to 3 days — and if you miss the harvest window by just 5 days, that elegant 15cm courgette becomes a marrow-sized, watery disappointment. The answer is not to give them away again. So, get ready. The answer is courgette fritters, made in 25 minutes, using whatever fresh herbs are bolting in your garden right now.
Courgette plants are programmed for abundance. Once the first female flowers set fruit in summer heat, the plant shifts into overdrive.
Warm nights above 15°C accelerate that cycle dramatically. What looks like one small courgette on Monday is a 40cm woody beast by Saturday; at that size, the flesh is mostly water and the seeds have already hardened.
Harvest at 15 to 20cm. Every time.
That is the window where the flesh is firm, faintly sweet, and holds its shape when grated. Anything beyond 25cm is already losing flavour to water content.
The RHS recommends checking courgette plants every 2 days during peak season — not weekly, not “when you remember.” This is non-negotiable for success.
If you have already got oversized ones, do not compost them yet. Grate them, squeeze hard with a clean kitchen towel, and freeze in 200g portions.
You will have fritter batter sorted well into autumn.
The plant interprets an unharvested fruit as reproductive success. It slows flower production.
Fewer new courgettes follow.
Leaving fruit on the plant is the single fastest way to end a productive season early. Beyond that, oversized courgettes left in summer heat begin to rot at the base, attracting fungal issues like powdery mildew that spread to the whole plant within 7 to 10 days.
Pick them. Even if you have no immediate plan for them, pick them.
This uses whatever you have. No specialist ingredients.
Grate 400g of courgette (about 2 medium ones), squeeze out every drop of moisture — this step takes 90 seconds and you cannot skip it. The fritters will steam instead of fry and turn grey rather than golden, a truly dodgy outcome.
Combine the dry grated courgette with:
Heat a heavy pan — cast iron if you have it — with 2 tablespoons of olive oil until it shimmers, about 2 minutes on medium-high. Drop heaped tablespoons of the mixture in.
Press gently. Do not touch them for 3 to 4 minutes.
Flip once, cook another 3 minutes. The smell when they catch the heat properly — that nutty, herby, slightly caramelised edge — is exactly what you are aiming for.
Serve immediately with a dollop of thick Greek yoghurt and lemon zest. Or cold the next day, which honestly works just as well. But, for matching herbs from the garden to your cooking, harvest your herbs before summer heat steals their flavour — timing the cut changes everything about how they taste in the pan.
Yes, it is fiddly. But it is absolutely non-negotiable. Do it anyway — the difference is night and day.
Courgette fritters are a base, not a fixed recipe. As your garden shifts through summer, fold in what is available:
And if the glut genuinely overtakes you, the classic ratatouille technique from French home cooking absorbs 1kg of courgette in one pan with tomatoes, peppers, and olive oil — freezes perfectly, tastes better reheated after 2 days.

Smart tip: Squeeze grated courgette in a clean towel for 90 seconds — this single step determines whether your fritters fry or steam.
Yes — grate them, squeeze out the excess moisture thoroughly, and use in fritters or freeze in 200g portions. Pull off the seedy core if it has already hardened.
Fresh thyme, mint, and basil all work well — mint does wonders for a lighter, summery result while thyme adds depth. Use whatever is shooting up fastest and needs cutting back right now.
Almost always too much moisture left in the courgette, or the oil was not hot enough before the batter went in. Squeeze harder and wait until the oil shimmers visibly before adding the mixture.
Mix it up to 2 hours ahead and keep it in the fridge, but do not let it sit longer — the salt draws out more moisture from the courgette and the batter becomes too wet to hold shape.
