Creamy Potato Leek Soup is a French-inspired classic made with tender potatoes, softened leeks, and a silky cream finish for a comforting bowl of warmth.
2 pounds Yukon Gold potatoes, peeled and diced
3 large leeks, white and light green parts only, thinly sliced
3 tablespoons butter
4 cups vegetable or chicken broth
1/2 to 3/4 cup heavy cream
1 sprig fresh thyme optional
Salt to taste
White pepper to taste
Fresh chives optional for garnish
Clean and slice leeks thoroughly.
Melt butter in large pot over medium-low heat.
Add leeks and cook gently 8 to 10 minutes until soft but not browned.
Stir in diced potatoes and broth. Add thyme if using.
Bring to gentle boil, then simmer 15 to 20 minutes until potatoes are tender.
Remove thyme and blend until completely smooth.
Stir in heavy cream and adjust seasoning.
Simmer briefly if needed and serve warm.
Do not brown the leeks. Blend carefully to achieve a silky texture. Soup thickens as it cools, so add broth when reheating if necessary.
