Ingredients for 2 servings

Check off ingredients as you go.

Contains fish, 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. Warm the oil in a large pan over medium heat and cook the leek for 6 minutes.

  2. Add the potatoes and stock and simmer for 12 to 15 minutes, until tender.

  3. Pour in the milk and bring it back to a bare simmer, with barely a bubble breaking the surface.

  4. Add the salmon and poach gently for 5 to 6 minutes, until it is opaque and flakes.

    Cooked when: 63°C / 145°F, or until the flesh is opaque and flakes easily. A food thermometer is the reliable way to tell.

  5. Stir in the dill, off the heat, and serve.

The useful detail

Keep the soup below a vigorous boil after adding fish. A boil breaks the milk and shreds the salmon; a bare simmer leaves both intact.

Make it work for you

One serving is A large bowl, half the pan. 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.

  • Trout instead of salmon

    Slightly leaner, with the same safe endpoint.

    Per serving: about 85 kcal less, about 1 g less protein, about 9 g less fat.

  • Cod instead of salmon

    Much leaner and whiter, and the soup is lighter.

    Per serving: about 160 kcal less, about 3 g less protein, about 16 g less fat.

  • Unsweetened soya milk

    Thinner, and less likely to split.

    Per serving: about 15 kcal less, about the same protein, about the same fat.

    Allergens: Adds soya; 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.

The richest soup in this group, because salmon is an oily fish. The potatoes and milk make it a meal rather than a starter.

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. Reheat it gently; the milk splits at a boil.
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.
