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. Heat the oven to 200°C / 400°F (180°C fan). Toss the butternut squash with half the oil on a tray and roast for 25 to 30 minutes, until tender and browned at the edges.

  2. Meanwhile, warm the rest of the oil in a large pan and cook the onion for 5 minutes.

  3. Add the roasted squash, beans, stock and sage and simmer for 5 minutes.

  4. Blend until smooth. Fill the blender no more than half full, take out the centre cap or hold the lid with a folded tea towel, and never seal hot soup in a closed jug.

  5. Warm it through and serve with the skyr spooned on top.

The useful detail

Vent a jug blender appropriately and avoid blending hot liquid in a sealed container. Steam expands as it whips and will lift the lid off, which is the commonest scald there is.

Make it work for you

One serving is A large bowl with 75 g of skyr. 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.

  • Pumpkin instead of butternut squash

    Wetter and milder, and it needs a little longer to roast.

    Per serving: about 40 kcal less, about the same protein, about the same fat.

  • Greek yoghurt instead of skyr

    Softer and a little richer.

    Per serving: about 10 kcal more, about the same protein, about 1 g more fat.

  • Butter beans instead of cannellini

    Creamier when blended. The figures use the same record.

    Per serving: about the same energy, about the same protein, about the same fat.

Estimated nutrition

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

A smooth soup given body by blended beans rather than cream, with the skyr adding most of the protein in the bowl.

Show calculation notes

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. Add the skyr to the bowl rather than the pan, so it does not split when reheated.
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.
