There are some soups that just feel like a hug in a bowl, and this Creamy Potato Leek Soup is exactly that. It's the kind of meal I make when the weather turns chilly and I need something warm, nourishing, and deeply satisfying. The leeks bring a subtle oniony sweetness, the potatoes make it thick and creamy, and a splash of cream ties it all together.

I first started making this soup on busy weeknights when I wanted something that felt fancy but didn't require a ton of effort. It's become a staple in my home, especially on days when the kids come in from playing outside with red noses and cold fingers. This soup warms them right up, and I love that I can have it on the table in about 40 minutes flat.

Why You'll Love This Recipe
About the Ingredients
3 tablespoons (42g) unsalted butter
Use good-quality butter for richness. Substitute with olive oil for a dairy-free version.
3 large leeks (about 1.5 lbs / 680g), white and light green parts only, sliced
Leeks can be gritty; slice and rinse well in a bowl of water. Substitute with 2 large onions if needed.
2 pounds (about 900g) Yukon Gold potatoes, peeled and diced (about 4-5 medium)
Yukon Golds give the creamiest texture. Russets work too, but may need more blending.
4 cups (960ml) low-sodium chicken or vegetable broth
Use homemade or store-bought. Low-sodium lets you control the salt. For vegetarian, use vegetable broth.
1 cup (240ml) heavy cream
Adds richness. For a lighter version, use half-and-half or whole milk, but the soup will be less creamy.
1 teaspoon salt, plus more to taste
Adjust to your preference. Sea salt or kosher salt works best.
1/2 teaspoon black pepper, freshly ground
Freshly ground pepper adds a nice kick. Adjust to taste.
1/4 teaspoon ground nutmeg (optional)
A pinch of nutmeg enhances the leek flavor. Substitute with a dash of cinnamon in a pinch.
Tips & Tricks
Don't skip rinsing the leeks
They trap a lot of dirt between layers. After slicing, soak in a bowl of water and swish to release grit, then lift out and drain.
Blend in batches
Hot soup expands when blended, so never fill the blender more than halfway. Hold the lid with a towel and start on low.
Adjust consistency
If the soup is too thick, thin with extra broth or milk. If too thin, simmer a few minutes to reduce.
Taste before serving
Flavors deepen as it sits, so always give it a final taste and adjust seasoning.
Pro Tips
Step-by-Step Instructions
1. Prep the Leeks
Trim the dark green tops and root ends from the leeks. Slice them lengthwise, then cut into thin half-moons. Place in a bowl of cold water, swish to release dirt, and lift out to drain.
2. Sauté the Leeks
In a large pot or Dutch oven, melt the butter over medium heat (350°F/175°C). Add the leeks and cook, stirring occasionally, until they are softened and translucent, about 8-10 minutes. They should be fragrant and slightly golden at the edges.
3. Add Potatoes and Broth
Add the diced potatoes and broth to the pot. Increase heat to high (400°F/200°C) and bring to a boil. Reduce heat to low (275°F/135°C), cover, and simmer until the potatoes are fork-tender, about 15-20 minutes.
4. Blend the Soup
Carefully transfer the soup in batches to a blender, or use an immersion blender directly in the pot. Blend until smooth and creamy. Be cautious with hot liquid—vent the blender lid to allow steam to escape.
5. Stir in Cream and Season
Return the blended soup to the pot (if using a blender). Stir in the heavy cream, salt, pepper, and nutmeg (if using). Heat over medium-low (300°F/150°C) until warmed through, about 5 minutes. Do not let it boil.
6. Taste and Adjust
Taste the soup and adjust seasoning if needed. If it's too thick, add a splash of broth or milk to reach your desired consistency.
7. Serve Hot
Ladle the soup into bowls and garnish with fresh chives, a drizzle of cream, or a few grinds of black pepper. Serve immediately with crusty bread or a side salad.
Delicious Variations
Add bacon
Crumble crispy bacon on top before serving for a smoky, salty crunch.
Herb-infused
Stir in fresh thyme or rosemary during the last 5 minutes of simmering for an aromatic twist.
Vegan option
Use olive oil instead of butter, vegetable broth, and replace cream with full-fat coconut milk for a dairy-free version.
How to Store Creamy Potato Leek Soup
Refrigerator
Store in an airtight container in the fridge for up to 4 days.
Freezer
Freeze in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating
Reheat gently on the stovetop over medium-low heat, adding a splash of broth or milk to loosen the consistency.
Frequently Asked Questions
Q: Can I make this soup without cream?
Yes, you can substitute the cream with whole milk or half-and-half for a lighter version, or use a can of coconut milk for a dairy-free option. The soup will still be creamy from the blended potatoes.
Q: How do I clean leeks properly?
Slice the leeks first, then soak them in a bowl of cold water, swishing with your hands to release any grit. Let them sit for a minute, then lift out with a slotted spoon, leaving the dirt behind.
Q: Can I use an immersion blender instead of a regular blender?
Absolutely! An immersion blender is actually easier and safer for hot soups. Just blend directly in the pot until smooth, being careful not to splatter.
Q: What potatoes are best for this soup?
Yukon Gold or other waxy potatoes are ideal because they become creamy when blended. Russet potatoes work too, but they can turn gluey if over-blended. For a chunkier texture, you can mash them instead.
Q: Can I freeze potato leek soup?
Yes, this soup freezes well for up to 3 months. Cool it completely, then store in freezer-safe containers. Thaw in the fridge overnight and reheat gently on the stove.
