A lower-calorie way to make Potato Leek Soup
Potato Leek Soup turns silky when white beans blend with the potatoes
Leeks, potatoes and white beans blended with milk produce a creamy Canadian cold-weather soup for about 330 calories per bowl.
Potato leek soup can feel luxurious without a carton of cream if its starch is managed deliberately. Leeks soften slowly without browning, potatoes simmer only until tender and white beans disappear into one blended portion of the pot. The remaining potato cubes give the spoon something to find, while milk rounds the finish after boiling has stopped.
What changes—and what stays
From commonly 450–650 calories with cream, butter and bacon garnish to 330 calories
Blend white beans with half the potato mixture, use two-percent milk instead of cream, and reserve some cubes so the bowl feels substantial. Leeks cooked below browning keep their gentle sweetness, thyme scents the broth and bean starch gives a satin finish. Black pepper and chives sharpen the mild base.

A cost rule that survives inflation
Potatoes, dried or canned beans and leeks make six large bowls from winter staples. No bacon garnish or cream purchase is needed to create body.
Ingredients for 6
Measure first; timing is part of how this recipe uses less fat.
- 800 gyellow potatoes
- 500 gleeks
- 360 gcooked white beans
- 1.1 Llow-sodium vegetable stock
- 400 ml2% milk
- 12 golive oil
- 8 gfresh thyme

Method
Each step includes heat, a visible cue, and a recovery.
Step 1 · follow the visible cue
Wash between every leek layer
Split leeks lengthwise, fan the layers under cold water and slice the pale parts thinly. Drain in a towel before they reach the pot.
Look for: No grit should remain in the folds and the sliced leeks should not drip water when lifted.
Step 2 · follow the visible cue
Soften without giving the leeks brown edges
Cook leeks in measured oil with a pinch of salt over medium-low heat for ten minutes, stirring before any edge colours.
Look for: Leeks should collapse into soft pale ribbons and smell sweet rather than toasted.
Step 3 · follow the visible cue
Separate the pieces that will stay whole
Add potatoes, beans, thyme and stock and simmer until potatoes are just tender. Lift out two cups of potato cubes before blending the rest.
Look for: A cube should crush under a spoon but still hold together when lifted from the broth.
Step 4 · follow the visible cue
Add milk below a boil and return texture
Blend the pot until smooth, stir in milk and reserved cubes, and warm gently without boiling. Finish with pepper and chives.
Look for: Soup should coat a spoon while visible potato cubes keep clean edges in the bowl.

The estimate uses the listed ingredients divided into 6 servings. Brand labels, trimming, and the amount left in the pan can change the result.
Keep the leftovers in the same spirit
Refrigerate for three days. Warm over low heat and add stock if it thickens; boiling can make the milk grainy and the potato gluey.

Frequently asked questions
Can I freeze potato leek soup?
It can become grainy after thawing. Freeze the blended stock-and-vegetable base before adding milk, then finish it fresh.
Can I use the green leek tops?
The tender light-green section is useful here. Save tough dark tops for stock, where they can be strained out.
