Roasted Pumpkin Soup

01Ingredients

1000g pumpkin, peeled and cubed
1 onion, roughly chopped
3 garlic cloves, whole and unpeeled
2 tbsp olive oil
1 tsp ground cumin
750ml vegetable stock
100ml cream (or coconut milk for dairy-free)
Salt and pepper, to taste
Fresh chives or crusty bread, to serve (optional)

02Method

Preheat oven to 200C. Toss pumpkin, onion, and unpeeled garlic cloves with olive oil and cumin on a baking tray.
Roast for 35-40 minutes until the pumpkin is tender and caramelised at the edges.
Squeeze the roasted garlic cloves out of their skins and add to a large pot with the roasted pumpkin and onion.
Add stock and bring to a simmer for 10 minutes.
Blend until smooth using a stick blender or upright blender.
Stir in cream, season with salt and pepper, and reheat gently. Serve topped with chives or crusty bread.

03Notes & substitutions

Swap cream for coconut milk for a dairy-free version - the flavour shifts slightly sweeter but works well.
Add a pinch of chilli flakes or a swirl of chilli oil for a flavour lift.
No stick blender? Blend in batches in an upright blender, leaving the lid slightly vented to let steam escape.
Vegetarian as written.

04Common mistakes

Skipping the roast — boiling pumpkin instead of roasting it loses the caramelisation that gives this soup depth; don't skip the oven step.
Peeling the garlic before roasting — roast it whole in its skin, then squeeze it out afterwards; peeled cloves burn instead of caramelising.
Blending while too hot — let the soup cool slightly before blending in an upright blender, or built-up steam can force the lid off.

More About This Recipe

06Ingredient notes

Pumpkin. A drier, denser variety like Kent or Jap gives a thicker, richer soup than a wetter variety like butternut - either works, but expect to adjust the final stock quantity slightly depending on which you use.

Garlic. Roasted whole and unpeeled, it turns soft and sweet rather than sharp - this is a technique difference from raw garlic, not just a shortcut.

Cream. Added at the end, off the boil, so it enriches the soup without any risk of splitting.

07Troubleshooting

Soup tastes flat. Almost always needs more salt, or the pumpkin wasn't roasted long enough to properly caramelise - a few extra minutes in the oven makes a difference.
Soup is too thin. Simmer uncovered for a further 10 minutes to reduce, rather than adding thickener.
Soup is too thick. Add extra stock, 100ml at a time, until it reaches the consistency you want.
Soup splits or looks grainy. The cream was likely added while the soup was still at a rolling boil - let it drop to a gentle simmer first.

Frequently Asked Questions

Why roast the pumpkin instead of just boiling it?

Roasting caramelises the natural sugars in the pumpkin, giving depth of flavour that boiling can't replicate - it's the single biggest difference between a flat-tasting soup and a rich one.

Can I make this dairy-free?

Yes - swap the cream for coconut milk in equal quantity. The flavour shifts slightly sweeter but works well with the roasted pumpkin.

Can I freeze pumpkin soup?

Yes - it freezes well for up to 3 months, better than most soups, since pumpkin holds its texture through freezing and reheating.

Why is my soup too thin or too thick?

Too thin: simmer uncovered for a further 10 minutes to reduce. Too thick: add extra stock 100ml at a time until it reaches the consistency you want.
