Ingredients

• 500g Hokkaido squash
• 300g Brussels sprouts
• 2 tbsp olive oil
• 600g cod fillet
• 30g hazelnuts
• 40g butter
• 12 sage leaves
• 1 unwaxed lemon
• 1 pinch of salt
• 1 pinch of pepper

Method

You’ll need: oven · frying pan · baking tray · chopping board · knife · grater

1. Preheat the oven to 200 °C (180 °C fan). Cut the Hokkaido squash, skin on, into wedges and halve the Brussels sprouts.
2. Toss the veg with the olive oil, salt and pepper and roast on a baking tray at 200 °C for 15 minutes.
3. Pat the cod dry, salt it and lay it between the veg. Bake everything for a further 10 to 12 minutes, until the fish is no longer translucent.
4. Roughly chop the hazelnuts. Melt the butter in a frying pan and fry the sage and hazelnuts in it for 3 minutes, until the butter smells nutty.
5. Grate a little lemon zest into the sage butter and add a squeeze of lemon juice.
6. Divide the squash, sprouts and cod between plates and pour the sage butter over the top.

Good to know

Here the cod cooks on the same tray as the squash and Brussels sprouts. At the end, brown butter with sage and hazelnuts goes over the top. An autumn dinner with little washing-up and few carbs.

Swaps

Cod → coley. Brussels sprouts → broccoli. Hazelnuts → pumpkin seeds (nut-free). Butter → olive oil (dairy-free).

Cooking tips

Thick pieces of fillet need 2 minutes longer; the fish is done when it flakes apart with a fork. Take the butter off the heat as soon as it's light brown.
