Nigel Slater’s recipe for roasted summer vegetables

Served with crusty bread and a herby sauce, there’s nothing nicer for a laid-back lunch

Ingredients

new potatoes

400g

summer carrots

350g

beetroot, raw

500g

banana shallots

4

olive oil

4 tbsp

chilli flakes

0.5 tsp

cumin seeds

1 tsp

ground coriander

2 tsp

garlic

3 cloves

courgettes

400g

summer squash

250g

bushy sprigs thyme

8

rosemary

4 sprigs

red wine vinegar

2 tbsp

garlic

2 cloves

mint leaves

10g

coriander

15g

natural yoghurt

350ml

In summer, I roast vegetables early in the day, before the kitchen heats up, then let them cool to room temperature for lunch. I start with onions or, preferably, the large oval shallots the size of a Christmas bauble, that roast sweetly. I then introduce whatever summer vegetables I have to hand. This week there were long spring carrots, beetroots the size of golf balls and new flaky-skinned potatoes from Jersey.

Once the root vegetables are approaching tenderness, I add the softer sort, the pale-skinned courgettes and deep yellow summer squash, occasionally a handful of tomatoes or perhaps some radishes that have gone beyond their best. The melange of vegetables changes according to what I have or need to use up. A few caveats, I never add pumpkin or parsnips, reserving those for winter roasts, or large turnips which have a tendency to turn bitter in the oven’s heat. (The tiny summer ones are good.) And should the courgettes or tomatoes collapse as they roast, that is fine; their mingling with the olive oil and making the dish juicy and sweet.

Intended as a lunch dish with crusty bread to soak up the juices, we finished this off the following day, the softened vegetables piled onto rounds of toast. We had finished the yoghurt sauce that I made to trickle over it, so let it speak for itself, the juices soaking in to the toast underneath. I sometimes stir in a spoonful or two of harissa paste as the vegetables cook, especially if the weather is on the cooler side. The recipe changes according to what is around.

This week has seen more than a few soft fruits in the kitchen. Peaches and kesar mangoes, which I have been eating for breakfast, and apricots (some really fine ones this year) which have been grilled and served warm. Some of the latter were stoned and stuffed with mascarpone, others wallowed in a bath of a rose-scented syrup and thick sabayon-style custard. You can make a syrup with just sugar, water and rosewater but this time I made one with an overblown bloom from the garden – a high-scented dark rose that I knew had not been sprayed. It may be my imagination, but I find the syrup all the more heady made with the darker coloured roses.

Method

Put a medium sized pan of salted water on to boil for the potatoes. Scrub them, cut them in half then add them to the boiling water and let them cook for 20 minutes. Heat the oven to 200C/gas mark 6.

Peel the shallots and halve them lengthways. (If you are using onions, cut them into thick wedges.)

Trim the carrots and cut them in half lengthways. Scrub and trim the beetroots, then cut them in half and then into thick wedges. Put the shallots, carrots and beetroots in a large, deep roasting tin, pour in the olive oil, season with salt and ground black pepper, the cumin and coriander. Peel and thinly slice the garlic then add to the vegetables. Drain the potatoes and add to the roasting tin, toss everything together, then roast in the preheated oven for 30 minutes.

Cut the courgettes and summer squash into large pieces, though nothing bigger than you would want on your fork. Remove the roasting beetroots and carrots from the oven, add the courgettes and squash, the springs of rosemary and thyme, then return to the oven for about 25-30 minutes, turning the vegetables over carefully when necessary.

To make the herb sauce: Peel the garlic and finely grate to a paste. Chop the mint leaves and then the coriander stems and leaves, then stir into the yoghurt with the garlic paste. Season with salt and, if you wish, a little pepper.

Check the vegetables for doneness and adjust the cooking time accordingly. When the vegetables are ready, lift them out onto a serving dish. Put the roasting tin over a moderate heat and pour in the red wine vinegar. Let the vinegar bubble with the roasting juices, while you stir with a wooden spatula, gently dissolving the caramelised sugars. Pour over the roasted vegetables on the serving dish.

Trickle the yoghurt dressing over (or if you refer, pass it round in a small bowl).
