Why choose a slow cooker soup?

Slow cooker soups offer:

• Minimal preparation time
• Rich, developed flavours
• Easy one-pot cooking
• Budget-friendly ingredients
• Nutritious meal option

Can you make sweet potato soup in a slow cooker?

Yes – using a slow cooker is a great way to bring out the natural sweetness of the sweet potatoes while letting the spices gently infuse the soup. It’s a hands-off, low-effort way to make a flavour-packed bowl.

When do I add the halloumi?

Halloumi is best added just before serving. Simply pan-fry or air fry it until golden and crispy, then place it on top of the hot soup. This keeps the texture perfect and stops it going rubbery in the slow cooker.

Can I make this soup in advance?

Yes – this sweet potato soup is ideal for batch cooking. Store in an airtight container in the fridge for up to 3–4 days, or freeze it (without the halloumi) for up to 3 months.

Is this a vegetarian recipe?

It is! This slow cooker soup is completely vegetarian and packed with protein from the halloumi, making it both satisfying and nutritious.

Can I make it vegan?

Yes – just swap the halloumi for a vegan cheese alternative or skip it entirely and top with roasted chickpeas or crunchy seeds for added texture.

Do I need to blend the soup?

Blending is optional depending on your texture preference. For a silky, creamy finish, use a hand blender. Or leave it chunky for a more rustic, hearty feel.

Can I use other vegetables in this soup?

Absolutely – carrots, butternut squash, or red peppers work really well with the sweet potato and spices if you want to mix it up or use what you have at home.

What should I serve with it?

This soup is great on its own or served with crusty bread, naan, or a light green salad. The crispy halloumi on top adds extra texture and saltiness that finishes the dish beautifully.
