Nonna's note

Potatoes are starchy enough to make this silky with no cream at all - provided you blend it while hot and do not overdo it, which turns potato gluey.

Method

5 steps · tap one to tick it off

Tips

  • Lift the leeks out of the water. After swishing the slices in a bowl, scoop them out by hand so the grit stays at the bottom. Pouring them into a colander tips it back over.

  • Use only the white and pale green. The dark green leek tops are tough and turn the soup a murky color. Save them for stock.

  • Blend in short pulses. A stick blender, pulsed, stops at smooth before the potato turns gluey. A countertop blender on high overworks it in seconds.

Swaps

  • No thyme? Dried thyme, about a third as much, or a bay leaf removed before blending.

  • No butter? Olive oil. The soup turns out slightly fruitier and dairy-free.

  • No vegetable broth? Water with an extra pinch of salt. Milder, so season it boldly.

Storage

  • Fridge: 3 to 4 days in a sealed container. It thickens as it sits, so thin it with broth or water.

  • Freezer: 2 to 3 months for best quality. The potato turns slightly grainy; whisk it well as it reheats.

  • Reheat: In a pot over medium-low heat with a splash of broth, stirring until steaming hot (75°C in the center).

Fridge and reheating follow Illinois Extension; freezer times are for quality and follow the University of Nebraska-Lincoln, as on what freezes and what does not.
