Preheat an oven or air fryer to 180c / 160 c fan / 350f / gas mark 4.
Cut the butternut squash in half lenthways, scoop out the seeds.
Rub the flesh side of the squash half with oil and sprinkle a pinch of the herbs and spices and season with salt and pepper.
Roast in an oven for 50 minutes or an air fryer for 40 minutes. The flesh should be soft, if not, give it longer.
You can roast 2 fresh peppers (topped and deseeded) at the same time as the squash or use jarred peppers, which I did this time.
Add the scooped out flesh of the butternut squash with the peppers and the rest of the herbs and spices to a blender or food processor with the vegetable stock and whizz until smooth.
If you don't have a food processor or blender, you can use a stick blender.
Heat in a pan or microwave, or pop in the fridge for later.
Serve with a swirl of cream and small dollops of pesto.
Enjoy!
Notes
You can use jarred roasted peppers (sometimes called pepper antipasti), without the oil or roast 2 red peppers at the same time as the butternut squash.
Don't throw out the seeds. Clean and dry them, then toss them in olive oil and dried herbs or spices and salt and pepper, then bake them for a few minutes in an air fryer or oven until crisp.
Once cool, you can store this gorgeous creamy soup in an airtight container in the fridge for 3-4 days.
Make it ahead, cool it and freeze in in portions in freezer bags or an airtight container for 3-4 months.
