Contains milk. Check the labels on packaged ingredients:

  • vegetable stock. Vegetable stock often contains celery, and some contain milk or gluten; check the label, especially if you need it vegan.

Cooking steps

  1. Rinse the red lentils in a sieve under cold water until the water runs clear. It takes about a minute and it decides how the soup tastes.

  2. Soften the diced onion in the oil over medium-low heat for 8 minutes.

  3. Add the cumin and turmeric and cook for a full minute before any liquid goes in.

  4. Add the diced pumpkin, the rinsed lentils and the stock. Bring to the boil, then simmer, partly covered, for 22 to 28 minutes, until the lentils have collapsed and the pumpkin gives to a spoon.

  5. Blend until smooth. Serve with the yoghurt spooned in and the coriander scattered over.

The useful detail

Rinse the lentils until the water runs clear. The starch and dust that come off them are what makes an unrinsed lentil soup cloudy, slightly gritty and oddly dull.

Make it work for you

One serving is A deep bowl with a spoonful of yoghurt. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Butternut squash instead of pumpkin

    Sweeter and denser, and it gives a thicker soup.

    Per serving: about 45 kcal more, about the same protein, about the same fat.

  • Quark instead of Greek yoghurt

    Thicker and sharper against the spice.

    Per serving: about the same energy, about the same protein, about 1 g less fat.

  • Leave out the yoghurt

    The soup becomes vegan and loses about 7 g of protein a serving. A squeeze of lemon juice replaces the sharpness.

    Allergens: Removes milk.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

A blended soup that still carries real protein, because the lentils are the body of it rather than a thickener, with the yoghurt adding more on top.

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 2. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Cool it quickly, cover and refrigerate within 2 hours. The FDA chart gives soups and stews 3 to 4 days. It thickens to a paste in the fridge; loosen it with stock or water as it reheats.
In the freezer
The same chart gives soups and stews 2 to 3 months in the freezer for best quality.
Reheating
Reheat until it reaches 74°C / 165°F, steaming hot throughout, stirring so it heats evenly.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
