Why Spring Lamb Suits a Lighter Stew

Spring lamb is milder, sweeter and leaner than the hogget and mutton we reach for in January, which makes it ideal for a lighter sort of stew. Where a winter casserole leans on root vegetables, red wine and three slow hours in the oven, this one leans on leeks, early peas, asparagus and a generous fistful of soft herbs. It still eats like a proper family dinner — tender meat, a savoury broth, plenty of bread for mopping — but it feels fresher on the plate, which is exactly what you want when the evenings start stretching out.

The whole thing is ready in under an hour, and most of that is unattended simmering. The trick is cutting the lamb small — 3cm chunks rather than big braising pieces — so shoulder or neck fillet gives up its collagen in about half an hour instead of three. You get the flavour of a slow-cooked stew with none of the waiting.

What You'll Need

• 700g boneless lamb shoulder or neck fillet, cut into 3cm chunks
• 2 tbsp plain flour (optional, for a slightly thicker broth)
• 2 tbsp rapeseed or olive oil
• 1 large onion, diced
• 2 leeks, white and pale green parts only, sliced
• 3 garlic cloves, sliced
• 500ml lamb or chicken stock, plus a splash of water
• 350g new potatoes, halved if large
• 150g podded peas — frozen are perfectly good here
• 150g asparagus, woody ends snapped off and cut into short lengths, or purple sprouting broccoli
• A large handful of spinach
• A small bunch each of mint, flat-leaf parsley and dill
• Finely grated zest of 1 lemon
• 20g cold butter
• Salt and freshly ground black pepper

Building the Base: Browning Is Where the Flavour Lives

Pat the lamb dry with kitchen paper — wet meat steams rather than browns. Heat a tablespoon of the oil in a wide, heavy casserole over a medium-high heat until it shimmers, then brown the lamb in three batches. Give each batch a good three or four minutes without moving it about too much, turning only when the underside is properly coloured. Crowd the pan and the meat will release water and go grey. As each batch finishes, tip it onto a plate.

Turn the heat down to medium. Add the rest of the oil, then the onion and leeks with a good pinch of salt. Cook for eight to ten minutes until soft and glossy but not coloured — salt early here, as it draws out moisture and speeds things along. Stir in the garlic for a minute, then the flour if you're using it, and cook that out for another minute so it tastes of toast rather than chalk.

Return the lamb and any juices from the plate, pour in the stock, and scrape the base of the pan with a wooden spoon to lift all the sticky brown goodness. Bring to a bare simmer — a lazy bubble, not a rolling boil — and cook with the lid ajar for 25 minutes.

The Last Fifteen Minutes: Potatoes, Peas and Timing

Add the potatoes and simmer for 12 to 15 minutes, until a knife slides in easily. Then add the peas and asparagus and cook for just four or five minutes. This is the part people rush, and it's the part that matters most: green vegetables need the least time and give the most colour. Drop the spinach in for the final minute, just until it wilts.

Now take the pan off the heat entirely. Chop the herbs fairly finely, stir them through with the lemon zest and the cold butter, and leave the stew to sit for five minutes. Taste, then season properly — a stew usually needs more salt than you think, and a good grind of pepper.

Kitchen Skills Worth Keeping

• Brown in batches, always. It takes an extra five minutes and it is the single biggest difference between a thin, pale stew and a rich one.
• Add green vegetables at the end. Frozen peas go in straight from the freezer; there's no need to defrost them, and they'll stay sweet and bright.
• Finish off the heat. Soft herbs such as dill, mint and parsley turn dull and grassy if they're boiled. The cold butter, swirled in at the end, emulsifies the broth and gives it a lovely sheen.
• Adjust the consistency last. Too thin? Simmer uncovered for five minutes. Too thick? A splash of stock or just hot water will loosen it without diluting the flavour much.

Variations, Serving and Leftovers

The formula is flexible, so use what's good near you. A handful of broad beans podded and slipped out of their skins is a lovely addition, as are early carrots cut into batons and added with the potatoes. Little gem lettuce hearts stirred in for the final three minutes sounds odd but is a genuine spring classic — braised lettuce turns silky and sweet. If you can get wild garlic, shred a few leaves in with the herbs.

Serve with crusty bread and nothing else, or with buttered new potatoes if you've skipped them from the stew. A sharp green salad on the side cuts through the richness nicely.

Leftovers keep well in the fridge for two days — cool them quickly and get them in a container rather than leaving the pan on the hob. Reheat gently with a splash of water, and add a few fresh herbs at the end, as the ones from yesterday will have faded. It freezes for up to two months, though the peas will lose a little of their bite. To scale up for a crowd, double everything except the stock, and add only half again as much liquid.
