Bring to a boil, then reduce heat and simmer for 20–25 minutes until potatoes are tender.
Blend the soup:
Remove from heat and use an immersion blender (or transfer to a blender) to puree until smooth.
Finish with cream:
Stir in heavy cream if desired. Adjust seasoning with salt and pepper.

Cooking Tips
Use only the tender parts of leeks for a delicate flavor.
For extra smooth soup, strain through a fine mesh sieve after blending.
Adjust cream amount for lighter or richer texture.
