Maple Roasted Brussels Sprouts with Chestnuts

Brussels sprouts have had a rough press, and most of it is deserved — but only if you boil them to a khaki mush and serve them with a shrug. Roasted hard on a hot tray and finished with maple syrup, they emerge with dark, lacquered edges, a tender centre and a sweetness that quietly converts the doubters. Add chestnuts and you have a side that feels festive without any real effort, and it earns its place at a plain Sunday roast in February just as happily as it does beside the Christmas bird.

Why maple syrup and sprouts belong together

Sprouts carry a natural bitterness, and bitterness loves sweetness. Maple syrup does more than mask it, though — the sugars caramelise against the charred cut faces and give the sprouts that sticky, almost roasted-on glaze you get on good roast parsnips. Chestnuts bring the other half of the equation: a soft, floury, faintly sweet nuttiness that soaks up the syrup and stops the whole thing tasting one-note.

The other reason this works is temperature. A very hot oven drives off moisture fast, so the sprouts brown rather than steam. Get that right and the texture does the rest — crisp outer leaves, yielding middles, no water pooling in the tin.

What you'll need

For four to six as a side:

• 800g Brussels sprouts, trimmed and any tired outer leaves removed
• 2 tbsp olive oil or cold-pressed rapeseed oil
• 200g vacuum-packed cooked chestnuts, halved (a 400g tin, drained, works too)
• 2 tbsp maple syrup — a darker, more robust grade gives a deeper flavour than a pale one
• ¾ tsp fine sea salt and a good grind of black pepper
• 25g butter, optional but recommended
• To finish: flaky salt, a squeeze of lemon, or a teaspoon of balsamic vinegar
• Optional extras: a few sprigs of thyme, the zest of half an orange, or a scattering of smoked paprika

Method: the reliable version

Heat the oven to 220°C conventional, 200°C fan, gas mark 7. Slide a large baking tray or shallow roasting tin onto the top shelf to get properly hot — this takes about ten minutes.

• 1. Halve the sprouts through the root so they hold together, and leave small ones whole. Toss them in a bowl with the oil, fine salt and pepper until every sprout is glossy.
• 2. Tip them onto the hot tray and spread them out in a single layer, cut sides down. If they're at all crowded, use two trays — this is the difference between caramelised and soggy.
• 3. Roast for 18–20 minutes, without stirring, until the cut faces are deep golden and a few outer leaves have gone dark and crisp.
• 4. Meanwhile, toss the chestnuts with a teaspoon of oil so they don't dry out.
• 5. Pull the tray out, scatter over the chestnuts, drizzle the maple syrup evenly and turn everything with a spatula. Return to the oven for 8–10 minutes.
• 6. Watch it at this stage — maple catches quickly. You want bubbling, sticky edges, not black ones.
• 7. Off the heat, stir through the butter if using, then finish with flaky salt and either lemon juice or balsamic. Both cut through the sweetness and sharpen the whole dish.

Make it your own

Add 100g of diced pancetta or smoked bacon to the tray for the first roast and the fat does half the seasoning for you. A teaspoon of smoked paprika in with the oil gives a gentle warmth that suits a roast pork loin. Thyme is the safest herb here; rosemary can bully the maple. If you want it sharper, add the orange zest at the end rather than the start, so it stays bright.

For a vegetarian version that still feels like a centrepiece, toss the finished sprouts with cooked Puy lentils and a spoonful of crème fraîche.

Getting ahead, and using up leftovers

You can blanch the sprouts for three minutes, refresh them in cold water and drain thoroughly up to a day ahead. Dry them well — wet sprouts steam — then roast as above, shaving five minutes off the first stage. Alternatively, roast the sprouts and chestnuts completely, cool, and reheat at 200°C fan for eight minutes with the maple drizzled over at the last moment.

Leftovers are excellent chopped into a frittata, folded through pasta with blue cheese, or piled onto toast with a fried egg. They also eat very well at room temperature, which makes them a sensible thing to take to a table where oven space is contested.

What to serve it with

Roast chicken, roast goose, pork with cider, glazed ham, good sausages, or a nut roast — this side is unfussy enough to sit beside all of them. The one thing to remember is that it's sweet, so balance it with something sharp: braised red cabbage with vinegar, a mustardy gravy, or a bitter leaf salad. British sprouts are at their best from November through to February, and chestnuts arrive at the same time, which is why the pairing feels so natural. Buy sprouts on the stalk if you can — they keep far better and the smaller ones roast beautifully whole.
