Donal Skehan’s autumn pasta

Method

1. Preheat the oven to 200°C/180°C fan/400°F/Gas 6.

2. Place the pumpkin on a large baking sheet with the thyme sprigs and toss in the olive oil until all the pieces are coated. Season generously with salt and pepper. Roast in the oven for 40 minutes, or until tender and caramelised at the edges. Once cooked, keep warm.

3. While the pumpkin cooks, place a large heavy-based frying pan (skillet) over a medium-high heat and add the butter. Add the onions and season generously, tossing to coat completely in the melted butter. Reduce the heat and cook gently until the onions are sweet and caramelised, about 10-15 minutes.

4. Towards the end of the pumpkin cooking time, bring a large pan of water to the boil and generously season with salt. Once boiling, add the pasta and cook until al dente. Drain and reserve a cup of the starchy cooking water for use in the sauce.

5. Increase the heat back up under the pan with the onions, then add the reserved pasta water and bring to a steady simmer. Meanwhile, mash half the cooked pumpkin and add this to the onions. Crumble in almost all of the blue cheese (keep a little back to serve) and stir until you have a smooth, creamy sauce. Working quickly, add the pasta to the pan and stir through until completely coated.

6. Serve the pasta hot in warmed plates topped with the remaining pumpkin slices and blue cheese. Sprinkle with toasted crushed walnuts and top with a generous drizzle of the best-quality extra virgin olive oil you have to hand and a last seasoning of sea salt and black pepper.
