Ingredients for slow cooker butternut soup
500g butternut squash, peeled and cut into cubes
1 tablespoon of olive oil
Half a teaspoon of chopped red chilli (if you don’t like heat, leave it out)
1 teaspoon of ground turmeric
A 400ml tin of coconut milk
1 carrot, grated
500ml of vegetable stock
2 cloves of garlic, crushed
1 teaspoon of curry powder
A thumb-sized piece of fresh ginger, peeled and grated
2 nuggets of frozen spinach, steamed
2 tablespoons of single cream (optional)
sea salt and freshly ground black pepper
To serve:
single cream
a handful of steamed spinach leaves
Method
So start by peeling and cubing your butternut squash into evenly sized chunks. Place the prepared squash directly into the drawer of your air fryer, drizzle with olive oil, and toss to coat each piece evenly. This helps the squash roast nicely, giving it a slightly caramelised flavour and a soft, tender texture.
Then set your air fryer to 180°C and cook for around 10 minutes, giving the basket a shake or turning the squash halfway through to ensure even cooking. You want the edges to start browning slightly while the inside becomes fork-tender.
If you prefer, you can roast the squash in a conventional oven. Simply spread the oiled squash on a roasting tray and cook at 180°C for 15 to 20 minutes, turning once or twice until golden and softened.
Once the squash is cooked, transfer it into your slow cooker. Add all remaining ingredients – such as chopped onion, garlic, vegetable stock, and your choice of herbs and spices – but hold back the spinach and cream for now.
Set the slow cooker to low and cook for 4 to 5 hours, stirring occasionally. The long, gentle cooking time allows all the flavours to develop and meld beautifully.
With one hour left, add the frozen spinach directly into the slow cooker and stir through. This gives the soup a boost of vibrant green colour and added nutrition.
Once everything is tender and well-cooked, use a hand blender to blitz the soup until smooth and velvety. If using, stir in a splash of single cream for a richer texture, and season to taste with salt and pepper.
Serve your squash soup hot, topped with a swirl of cream and a few steamed spinach leaves for garnish. My air fryer flat bread would also go very well with this dish.
Tips for Slow Cooker Butternut Soup
1. Peel and cube the squash evenly.
Butternut squash can take a while to cook, so make sure to peel it thoroughly and cut it into evenly sized chunks. This ensures it cooks at the same rate and blends smoothly.
2. Roast your squash first (optional but worth it).
For extra depth of flavour, roast the butternut squash cubes in the oven before adding to the slow cooker. It adds a lovely caramelised richness to the final soup.
3. Add aromatics early.
Onion, garlic, carrots, celery, and even apple are great additions. They bring out the natural sweetness of the squash and add layers of flavour.
4. Don’t add too much liquid at the start.
Butternut squash releases moisture as it cooks, and the slow cooker prevents evaporation. Use just enough stock to cover the squash as it is easier to thin it out later than fix a watery soup.
5. Season gently and adjust later.
Add a pinch of salt and pepper at the beginning, but save the final seasoning for after you blend the soup. This way, you won’t risk over-salting.
6. Use coconut milk or cream for richness.
Add a swirl of coconut milk, cream, or crème fraîche at the end for a creamy texture and a little luxury.
7. Blend until velvety smooth.
Use a stick blender straight in the slow cooker or transfer to a blender in batches. Blending thoroughly makes a big difference in texture.
8. Add toppings for texture and contrast.
Toasted seeds, a dollop of yoghurt, croutons, or crispy sage leaves take your soup from simple to special.
