Preheat your oven to 220°C/200°C fan/gas mark 7. Bring a large saucepan of water with 1/2 tsp salt to the boil for the potatoes.

Trim the butternut squash, halve lengthways, then scoop out the seeds (peel first if you prefer). Cut into 1-2cm chunks.

Halve and peel the onion, then cut each half into 6 wedges. Pop the diced butternut and onion onto a large baking tray.

Sprinkle the butternut and onion with the curry powder mix. Drizzle with oil, season with salt and pepper, then toss to coat. Spread out in a single layer. TIP: Use two baking trays if necessary.

When the oven is hot, roast on the top shelf until golden and cooked through, 25-30 mins. Turn halfway through.

Meanwhile, chop the potatoes into 2cm chunks (peel first if you prefer).

When your pan of water is boiling, add the potatoes and cook until you can easily slip a knife through, 15-20 mins.

Meanwhile, grate the cheese.

Pour the korma curry paste, creme fraiche, vegetable stock paste, sugar and water for the sauce (see pantry for both amounts) into a large frying pan on medium heat. Bring to the boil, then simmer until slightly thickened, 3-4 mins. 

Add the spinach to the pan a handful at a time until wilted and piping hot, 1-2 mins.

Once the veg has roasted, stir it through the sauce. Season to taste with salt and pepper. Add a splash of water if you feel it needs it.

Preheat your grill to high.

Once the potatoes are cooked, drain in a colander and return to the pan, off the heat.

Add the butter (see pantry for amount) and a splash of milk (if you have any) and mash until smooth. Season with salt and pepper.

Transfer the korma mixture to an appropriately sized ovenproof dish. Top with the mash, using the back of a spoon to smooth it out. Sprinkle over the cheese, then grill until golden and bubbling, 5-6 mins.

Meanwhile, boil a half-full kettle. Trim the green beans.

Pour the boiled water into a saucepan with 1/2 tsp salt and heat on high.

Bring the water back to the boil, then add the green beans and cook until just tender, 4-6 mins.

Once cooked, drain in a colander, then return to the pan. Season with salt and pepper. Toss in olive oil.

When everything's ready, divide the korma pie between your plates. 

Serve with the green beans on the side.

Enjoy!
