Roasted Butternut Squash and Red Lentil Soup with Coconut Milk, Turmeric and Ginger
Some recipes exist to impress. This one exists to restore.
It begins with butternut squash, roasted until its edges caramelise and its flesh turns sweet and yielding, which is the single step that separates a good squash soup from a truly extraordinary one. Roasting concentrates the flavour in a way that no amount of simmering can replicate, and it asks nothing of you beyond twenty-five minutes in a hot oven and the patience to let it happen.
From there, the soup builds quietly and generously. Red lentils dissolve into the base, adding a creaminess and a depth of plant-based protein that makes this as sustaining as it is beautiful. Coconut milk brings a silkiness that rounds every sharp edge. Turmeric, one of the most studied anti-inflammatory compounds in the natural world, gives the soup its extraordinary golden colour and its warm, earthy undertone. Fresh ginger brings heat and brightness. A squeeze of lime at the end lifts everything.
The result is a bowl that is simultaneously comforting and vibrant, the kind of food that makes you feel, from the first spoonful, that you have done something genuinely good for yourself. Which, after everything the blog post accompanying this recipe asks of you, feels like exactly the right note on which to end the week.
It serves four, which means leftovers for tomorrow, and tomorrow deserves this soup just as much as today does.
Roasted Butternut Squash and Red Lentil Soup with Coconut Milk, Turmeric and Ginger
Prep Time: 15 minutes Cooking Time: 45 minutes Total Time: 60 minutes Serves: 4
INGREDIENTS
• 900 grams butternut squash, peeled, deseeded and cut into roughly 3cm chunks
• 200 grams red lentils, rinsed thoroughly under cold water
• 400 milliliters full-fat coconut milk
• 900 milliliters good quality vegetable stock
• 1 large onion, roughly chopped
• 4 garlic cloves, roughly chopped
• 30 grams fresh ginger, peeled and finely grated
• 2 teaspoons ground turmeric
• 1 teaspoons ground cumin
• 1 teaspoons ground coriander
• 0.5 teaspoons smoked paprika
• 3 tablespoons extra virgin olive oil
• 2 limes, juiced
• 1 pinch sea salt and freshly ground black pepper
• 3 tablespoons fresh coriander leaves, to serve
• 4 tablespoons coconut cream or full-fat yoghurt, to serve
• 3 tablespoons toasted pumpkin seeds, to serve
• 1 teaspoons dried chilli flakes, optional
STEPS
1. Heat your oven to 200°C, 180°C fan, gas mark 6. Spread 900 grams butternut squash, peeled, deseeded and cut into roughly 3cm chunks across a large roasting tray in a single layer. Drizzle with one tablespoon of 3 tablespoons extra virgin olive oil, season generously with 1 pinch sea salt and freshly ground black pepper, and toss to coat. Roast for 25 to 30 minutes until the edges are deeply caramelised and the flesh is completely tender when pierced with a knife. This step is the foundation of the soup's flavour. Do not rush it and do not crowd the tray, if the squash is too close together it will steam rather than roast and you will lose the caramelisation that makes all the difference.
2. While the squash roasts, warm the remaining 3 tablespoons extra virgin olive oil in a large, heavy-bottomed saucepan over a medium heat. Add 1 large onion, roughly chopped with a generous pinch of 1 pinch sea salt and freshly ground black pepper and cook gently for 8 to 10 minutes, stirring occasionally, until completely soft and translucent. Do not rush this step. A properly softened onion is the quiet foundation of everything that follows. Add 4 garlic cloves, roughly chopped and 30 grams fresh ginger, peeled and finely grated and cook for two minutes more, stirring frequently, until fragrant.
3. Add 2 teaspoons ground turmeric, 1 teaspoons ground cumin, 1 teaspoons ground coriander, and 0.5 teaspoons smoked paprika if using to the pan. Stir continuously for one minute, coating the onion, garlic, and ginger in the spices. You will hear a gentle sizzle and the kitchen will begin to smell extraordinary. This brief toasting of the spices in the oil unlocks their flavour in a way that adding them to liquid alone never achieves. Watch the heat here: you want the spices fragrant and deepened, not burnt.
4. Add 200 grams red lentils, rinsed thoroughly under cold water to the pan and stir to coat in the spiced base. Pour in 900 milliliters good quality vegetable stock and bring to a gentle boil. Reduce the heat to a steady simmer and cook for 20 minutes, stirring occasionally, until the lentils have completely dissolved into the liquid and the base is thick and creamy. Red lentils require no soaking and break down beautifully on their own, which is precisely what makes this soup so foolproof.
5. Once the squash is roasted and the lentil base is ready, add the squash to the pan along with 400 milliliters full-fat coconut milk. Stir everything together and simmer gently for five minutes to allow the flavours to come together. Remove from the heat.
6. Using a stick blender directly in the pan, blend the soup until completely smooth and silky. If you prefer a little texture, blend three quarters of the soup and leave the rest as it is. Add the juice of 2 limes, juiced and stir through. Taste and adjust the seasoning generously. The lime is not optional: it is the element that makes the entire soup sing, lifting the richness of the coconut milk and sharpening the sweetness of the squash. Add more if you feel it needs it.
7. Ladle into warm bowls. Swirl a spoonful of 4 tablespoons coconut cream or full-fat yoghurt, to serve through each bowl. Scatter over 3 tablespoons fresh coriander leaves, to serve, 3 tablespoons toasted pumpkin seeds, to serve, and a pinch of 1 teaspoons dried chilli flakes, optional if you like heat. Finish with a final grind of black pepper and a small drizzle of olive oil. Serve immediately with warm crusty bread or toasted sourdough alongside, because a soup this good deserves something to dip into it.
**Hints & Tips**
**On the squash.** Peeling a butternut squash can feel like a commitment, and it is worth doing properly. A sharp, sturdy vegetable peeler works better than a knife for most of the squash, though the narrow neck is easier to peel with a knife. If you are short on time, many supermarkets sell pre-cut butternut squash that works perfectly well here. The flavour will be marginally less intense than a whole squash roasted from scratch, but the soup will still be excellent.
**On the turmeric.** Turmeric stains everything it touches, including chopping boards, hands, light-coloured clothing, and pale kitchen surfaces. Work with this knowledge rather than against it. A dark chopping board, an old wooden spoon, and an apron are your friends here. The staining is entirely worth it.
**On the ginger.** Fresh ginger is infinitely better than ground ginger in this soup. The flavour is brighter, more complex, and more aromatic. The easiest way to peel fresh ginger is with the edge of a teaspoon rather than a peeler or knife, which removes the thin skin without wasting any of the flesh. Freeze any unused ginger and grate it from frozen next time, it actually grates more easily frozen than fresh.
**On the coconut milk.** Use full-fat coconut milk rather than reduced-fat for this soup. The fat content is what gives the soup its silkiness and its body, and reduced-fat versions produce a noticeably thinner, less satisfying result. The difference is worth every calorie.
**On blending.** A stick blender used directly in the pan is the easiest and least messy approach. If using a stand blender, allow the soup to cool slightly before blending and never fill the blender more than halfway, as hot liquid expands when blended and can force the lid off with considerable force. Hold the lid firmly with a folded tea towel as an additional precaution.
**On the lime.** Do not skip it and do not be timid with it. The acidity of the lime is what balances the sweetness of the squash and the richness of the coconut milk. Start with the juice of two limes as directed, taste, and add more if the soup feels flat. It will not.
**On storing leftovers.** This soup keeps exceptionally well. It stores in an airtight container in the fridge for up to four days and actually improves overnight as the spices deepen and settle. It also freezes beautifully for up to three months. Freeze in individual portions for the evenings when cooking feels like too much and you deserve something wonderful anyway.
**On making it ahead.** This soup is an ideal candidate for batch cooking. Double the quantities, freeze in portions, and you have five minutes of reheating standing between you and one of the most nourishing bowls of food you can eat on a weeknight. Label and date the portions before freezing, future you will be grateful.
