What Are Leeks and Why Are They Great in Soup?
Leeks are a member of the allium family, related to onions and garlic, but with a milder, sweeter flavor. When sautéed gently and combined with starchy potatoes, they form the base of a creamy, luxurious soup. Their subtle flavor allows the richness of the potatoes and broth to shine without being overpowering.
Ingredients for Budget Potato Leek Soup
| Ingredient | Quantity |
|---|---|
| Leeks (white and light green) | 3 medium, sliced thin |
| Russet potatoes, peeled | 4 medium (about 1.5 lbs) |
| Unsalted butter | 2 tablespoons |
| Garlic, minced | 2 cloves |
| Vegetable or chicken broth | 4 cups |
| Heavy cream or milk | ½ cup |
| Salt | 1 teaspoon (to taste) |
| Black pepper | ½ teaspoon (to taste) |
| Olive oil | 1 tablespoon (optional) |
| Fresh thyme or chives (garnish) | 1 tablespoon (optional) |
Ingredient Notes:
- Leeks: Be sure to rinse leeks thoroughly; dirt hides between the layers.
- Potatoes: Russet potatoes give the creamiest texture, but Yukon Golds work too.
- Cream Options: For a lighter version, use half-and-half or whole milk; for dairy-free, sub with oat milk or cashew cream.
- Butter & Oil: Use both for a silky mouthfeel; skip the oil if using only butter.
How to Make Quick Potato Leek Soup
- Prep the Leeks: Slice off the dark green tops of the leeks and discard or save for stock. Slice the white and light green parts lengthwise and then crosswise into half-moons. Rinse in a bowl of water to remove any grit.
- Sauté the Base: In a large soup pot, melt butter over medium heat. Add the leeks and sauté for 5–6 minutes until softened but not browned. Stir in garlic and cook 1 more minute.
- Add Potatoes & Broth: Stir in chopped potatoes and pour in the broth. Bring to a boil, then reduce to a simmer. Cook uncovered for 15–18 minutes until potatoes are very tender.
- Blend the Soup: Use an immersion blender to purée the soup until smooth. Or carefully transfer in batches to a blender and purée.
- Finish with Cream: Return soup to low heat and stir in cream. Taste and season with salt and pepper.
- Serve & Garnish: Ladle into bowls and top with fresh herbs, cracked pepper, or a drizzle of olive oil.
Optional Add-Ins and Swaps
- Make It Vegan: Swap butter with olive oil and use oat milk or cashew cream.
- Add Protein: Stir in cooked shredded chicken or crumbled bacon before serving.
- Herb Twist: Add rosemary or tarragon for depth; thyme is a classic pairing.
- Top with Crunch: Serve with croutons, toasted nuts, or crispy shallots.
- Add Cheese: Stir in grated cheddar or Parmesan just before serving for richness.

Frequently Asked Questions about Potato Leek Soup
Q: Can I make this potato leek soup without cream?
A: Absolutely! The soup is still creamy when blended, thanks to the starch in the potatoes. Use extra broth or non-dairy milk if you want a lighter or vegan version.
Q: How long does potato leek soup last in the fridge?
A: Store in an airtight container for up to 4 days in the refrigerator. Reheat gently on the stovetop or in the microwave.
Q: Can I freeze this soup?
A: Yes, but if using cream, note that it may slightly separate when thawed. Stir well when reheating. Freeze in airtight containers for up to 3 months.
Q: What can I serve with potato leek soup?
A: Crusty bread, grilled cheese sandwiches, or a side salad make excellent pairings. You could also serve it as a starter before a main course.
Q: Why did my soup turn out gluey?
