Shops brim with squash, sweet potatoes and leafy greens, and diners turn to recipes that hug the ribs without bruising the wallet. A creamy sweet potato and coconut dahl does the job fast, keeps well, and brings a mood-lifting burst of orange to grey evenings.
A warm bowl for the cost-of-living squeeze
One pan. Twenty-five minutes. Four generous bowls. This dahl leans on store-cupboard pulses, seasonal roots and a can of coconut milk. The texture sits between stew and soup. The flavour is mild enough for children, yet layered with ginger, curry and cumin. Spinach melts into the mix for freshness and colour. Lemon at the table tightens the finish.
Four bowls on the table in 25 minutes for about £4.80. Creamy, aromatic and weeknight-proof.
What goes in
- 2 medium sweet potatoes, diced (roughly 500 g)
- 200 g red lentils, rinsed until the water runs clear
- 1 large onion, finely chopped
- 2 garlic cloves, crushed
- A thumb of fresh ginger, grated
- 400 ml coconut milk
- 300–400 g fresh spinach or two compact handfuls of frozen spinach
- 1 tbsp olive oil
- 1 heaped tsp mild curry powder
- 1 tsp ground cumin
- ½ tsp sweet paprika
- 1 vegetable stock cube and 600 ml water, or light homemade stock
- Salt and black pepper to finish
- Lemon wedges, fresh coriander or parsley, pumpkin or sunflower seeds (optional)
Step-by-step in 25 minutes
Warm the oil in a wide pot over medium heat. Soften the onion for 5 minutes, stirring. Add garlic, ginger and the spices. Stir for 60 seconds until fragrant.
Tip in the drained lentils and sweet potato. Crumble in the stock cube. Pour in 600 ml water. Bring to a steady simmer, cover, and cook for 15–18 minutes, stirring every few minutes so the lentils do not catch. Add a splash of water if it thickens too quickly.
Stir through the spinach until it wilts. Pour in the coconut milk. Simmer uncovered for 3–4 minutes so the sauce turns silky. Season well. Squeeze in a little lemon at the table.
Keep the heat gentle once the coconut milk goes in. Gentle simmer equals glossy, not split.
Why this humble dahl matters now
It is affordable. Red lentils are one of the lowest-cost proteins on the shelf. Sweet potato offers a soft sweetness, natural fibre and a bright dose of beta-carotene. Spinach brings iron and folate. Coconut milk gives body, so you do not need cream. The result is hearty without heaviness, and satisfying without pricey extras.
It is flexible. Swap spinach for kale. Use butternut if sweet potatoes are sold out. Adjust the curry powder to taste, or steer it smoky with a pinch of paprika. Serve with naan for dunking or spoon it over steamed basmati. A swirl of plain yoghurt cools the spice and adds tang.

Flavour moves that pay off
Lift the creamy factor
- Toast the spices in oil for a minute. That short step unlocks depth.
- Finish with a teaspoon of coconut oil for extra sheen.
- Add a handful of roasted pumpkin seeds at the table for contrast.
Balance sweetness and spice
Sweet potato and coconut need brightness. Lemon juice at the end sharpens every spoonful. A little fresh chilli warms without overpowering. Fresh herbs cool the palate and add aroma. Taste for salt at the end; lentils absorb seasoning as they cook.
Make it your own
Seasonal swaps and allergy-friendly tweaks
- No sweet potato? Use butternut squash or carrots cut small.
- No coconut? Try oat cream or unsweetened almond drink and a spoon of tahini.
- Gluten-free by default. If serving naan, pick a gluten-free flatbread.
- For a protein boost, stir in a tin of chickpeas during the final simmer.
Texture control
Prefer it soupier? Add 100–150 ml extra water with the coconut milk. Want it thicker? Simmer uncovered for a few minutes more, stirring. Mash a few cubes of sweet potato against the side of the pan to thicken naturally.
Serving ideas that earn applause
What to put alongside
- A bowl of basmati rice, cooked light and fluffy.
- Warm naan or chapatis for dipping.
- A spoon of plain yoghurt or coconut yoghurt and a dusting of garam masala.
- Lemon wedges, a drizzle of chilli oil, or a pinch of flaky salt.
Set the table with lemon, herbs and something crunchy. The last-second garnish makes it feel generous.
Smart storage and batch-cooking
Cook once, eat twice
This dahl tastes even better the next day after a night in the fridge. Chill leftovers within two hours and store in a sealed container for up to three days. Reheat gently with a splash of water or coconut milk until piping hot.
Freeze portions for up to three months. Thaw in the fridge overnight and reheat slowly. The texture remains creamy, and the spices settle in nicely.
Useful extras for the home cook
Timing tricks and shopping notes
Wash the lentils until the water runs clear; this reduces scum and keeps the pot tidy. Dice the sweet potato small to hit the 25-minute target. If using frozen spinach, squeeze out water before adding to avoid a thin finish.
To keep costs down, buy lentils in 1 kg bags, and stock cubes in multipacks. A lemon goes a long way here; use half for the pot and the rest at the table. Leftover coconut milk freezes well in an ice-cube tray for future sauces.
Nutrition at a glance
Red lentils bring plant protein and fibre that keep you full. Sweet potato contributes beta-carotene, which the body converts to vitamin A. Spinach supports iron intake and adds magnesium. The dish leans on healthy fats, so it satisfies without needing meat. For those tracking intake, the table above provides handy ballpark figures for planning.
