Maple Glazed Salmon with Roasted Greens

Weeknight cooking has a narrow window between "I really can't be bothered" and "let's just order something in", and a tray of maple glazed salmon fits neatly inside it. Everything happens on one baking tray in under half an hour: the greens go in first to soften and catch at the edges, the salmon follows, glazed and glossy, and by the time you've laid the table the whole thing is ready. It feels generous without being fussy, and it happens to suit the British growing calendar rather well. Spring asparagus, summer beans, autumn kale, winter leeks — the same method, a slightly different pile of vegetables each month.

Why maple syrup works so well with salmon

Maple syrup brings more to fish than simple sweetness. A good dark syrup has a faintly woody, caramel edge, and that note flatters the richness of oily fish far better than honey or caster sugar would. It also caramelises quickly, which is both the pleasure and the risk: brush it on and roast, and you get a lacquered, sticky surface; leave it too long under a fierce grill and you get a bitter crust that tastes of burnt sugar. Keep the heat moderate, the timing short, and you'll be fine every time.

For cooking, buy an amber or dark syrup rather than the palest grade. The delicate light syrups are lovely poured over porridge or folded into a sponge, but their flavour vanishes against mustard and fish. Dark syrup is also slightly thicker, so it clings to the fillet instead of sliding off into the tray. A 250ml bottle goes a long way — this recipe uses two tablespoons, leaving plenty for baking.

The glaze: a ratio worth memorising

Make this twice and you won't need the list again. The formula is roughly two parts maple syrup to one part mustard to one part something salty and sharp — soy sauce, tamari, or a splash of Worcestershire sauce. From there, add whatever aromatics you fancy: grated garlic, a little finely grated ginger, lemon zest, a pinch of chilli flakes.

• 2 tbsp dark maple syrup
• 1 tbsp Dijon mustard
• 1 tbsp soy sauce or tamari
• 1 small garlic clove, finely grated
• 1 tsp lemon juice or cider vinegar
• plenty of freshly ground black pepper

Whisk it in a small bowl or shake it in a jam jar. It should be thick enough to coat the back of a spoon but loose enough to brush — add a teaspoon of water if it's stiff, a little more mustard if it's watery. Make double and keep the rest in the fridge for up to a week; it's excellent on roast carrots, chicken thighs and thick slices of halloumi.

Choosing the salmon and the greens

For two people, look for two fillets of about 150–175g each, cut from the thick end of the side (sometimes sold as the loin) rather than the thin tail. Even thickness means even cooking, and a thicker piece stays juicy. Skin on, please: the skin protects the flesh, gives you something crisp to eat, and stops the fillet curling as it roasts. Ask for it to be pin-boned, or run your fingertips over the surface at home to check.

As for the greens, you want things that roast in ten to fifteen minutes without collapsing. Tenderstem broccoli, asparagus spears, purple sprouting, halved sugar snap peas, spring greens sliced into wide ribbons, cavolo nero stripped from its tough stems. Toss them with a tablespoon of rapeseed oil, a good pinch of salt and a few thin slices of lemon, spread them in a single layer, and give them a head start in the oven.

Roasting timings that actually work

Heat the oven to 200°C (180°C fan), gas mark 6. Roast the greens for 10 minutes while you pat the salmon dry with kitchen paper — dry skin crisps, wet skin steams. Sit the fillets skin-side down on a piece of baking parchment, brush generously with the glaze, and season. Pull the tray out, push the greens to the edges, and slide the salmon into the middle. Return to the oven for 10–12 minutes, depending on the thickness of your fillets.

The salmon is ready when it flakes at the thickest point but still looks slightly translucent in the centre — around 50–52°C if you have a thermometer to hand. Rest it for two or three minutes, then spoon over the sticky juices left on the parchment. If your greens aren't quite tender, lift the salmon onto warm plates, cover loosely with foil, and give the vegetables another five minutes.

Seasonal swaps and what to serve alongside

The method stays the same all year; only the vegetables change. In spring, asparagus and podded peas. In summer, courgette batons, green beans and a handful of cherry tomatoes added for the final eight minutes. In autumn, cavolo nero and thin wedges of squash — give those a 25-minute head start before the salmon goes in. In winter, halved leeks, parsnip batons and purple sprouting broccoli, which all take kindly to a sticky glaze.

Serve with new potatoes and a knob of butter, steamed rice, buttered orzo, or simply a hunk of good bread to mop up the tray. A spoonful of thick yoghurt loosened with lemon juice cuts through the glaze beautifully, as does a sharply dressed green salad. And if there's any glaze left in the jar, drizzle it over a plain yoghurt cake or a tray of roast plums — maple is far too good to reserve for one supper.
