There is a particular fatigue that sets in around the third week of July, when the people you usually cook for are away, the kitchen is too hot to want anything roasted, and the easiest thing is to stand at the counter eating crackers over the sink. I have done the sink-cracker dinner. It is not a moral failing. But cooking for one in high summer doesn't have to collapse into either a limp bag of supermarket salad or a takeaway you regret by 9pm.
The problem isn't motivation — it's the shopping math
Most recipes assume four mouths. Buy a bunch of coriander for one portion and you watch three quarters of it blacken in the fridge by Thursday. Multiply that across a week and the waste is both depressing and, at roughly £8–£12 of binned produce, genuinely expensive. The fix is not willpower. It is buying for flexibility rather than for specific dinners, then letting the week assemble itself.
Build the trolley around things that pull double duty and don't rot in 48 hours. A jar of good harissa (Belazu's rose harissa is about £3.50 and lasts months). A block of feta. Tinned chickpeas and butter beans, which in summer want nothing more than lemon, olive oil and whatever soft herb survived. Eggs, always. One protein you actually like — a couple of chicken thighs, a fillet of mackerel from the fish counter, a slab of halloumi. That is a week of dinners, and not one of them is a sad salad.
The five-minute assembly, not the recipe
A jar of beans, drained, with feta crumbled over, a glug of olive oil, lemon, and torn mint is dinner. It took ninety seconds and it is better than anything that arrives in a plastic clamshell.
This is the unlock for the single cook: stop thinking in recipes and start thinking in components. Roast a tray of cherry tomatoes and a red onion on Sunday evening when the oven won't make you miserable, and you've got a base that turns into pasta on Monday, folds through couscous on Tuesday, and sits under a fried egg on Wednesday. The Mediterranean already solved single-portion summer eating centuries ago. We just complicated it.
Protein is where people give up
Tinned fish deserves the rehabilitation it's been getting. A tin of sardines in olive oil, mashed onto sourdough toast with a squeeze of lemon and a crack of black pepper, is a proper dinner with real omega-3s and zero cooking. Mackerel is even better and the supermarket versions — John West, Fish 4 Ever — run £1.50 to £2.50 a tin. Eggs do the same job: a frittata made with three eggs and whatever vegetable is wilting uses up the fridge and reheats cold for lunch the next day, which no one ever tells you but is one of summer's quiet pleasures.
What to actually buy this week
- Beans and pulses in tins — chickpeas, butter beans, lentils. They keep forever and turn a handful of herbs into a meal.
- One soft herb and one hard one. Mint and parsley survive a week; basil and coriander do not, so buy those only if you'll use them in two days.
- A pot of full-fat Greek yoghurt — for breakfast, for thinning into a dressing with lemon and garlic, for dolloping on anything spicy.
- Frozen peas and frozen spinach, which are picked and frozen within hours and often beat the tired "fresh" version sitting under shop lights, among other freezer staples worth keeping.
The thing no one admits about portion sizes
Cooking for one means you will overshoot. A "single" portion of pasta is almost always two, and you'll eat the lot standing up because it's there. This is fine occasionally — but if you're trying to eat in a way that actually leaves you energetic in the heat rather than heavy and sleepy at 3pm, weigh the pasta once. Eighty grams dry is a real portion. It looks insultingly small in the pan and is exactly right on the plate.
There's a counterpoint worth naming. Some nights you don't want components or assembly or any of it. You want toast and a boiled egg and to be left alone. That is also nourishing — protein, slow carbs, done. The aim isn't a Pinterest grid of jewelled summer bowls. It's getting real food into yourself without the planning becoming a second job.
The freezer is your sous-chef
Batch cooking gets pitched as a Sunday-afternoon marathon, which is exactly why single people never do it. Scale it down. When you make that frittata or a pot of dal, make a touch more and freeze one portion flat in a bag. Three weeks of doing this and you've quietly built a stash of "I cannot face cooking" dinners that are still genuinely good for you. A homemade lentil dal pulled from the freezer beats the £4.50 ready-meal version on every count — cost, salt, and the simple fact that you made it.
Halloumi fries in four minutes and turns a plate of tomatoes into something you'd actually serve a friend. Keep a block in the fridge. On the worst, hottest, most-can't-be-bothered night of the week, that block is the difference between dinner and crackers over the sink.
