Easy Healthy Potato Leek Soup – Creamy 30-Minute

There's something about a bowl of potato leek soup that feels like a warm hug on a chilly day. I remember my grandmother making it on rainy afternoons, the scent of leeks and butter filling the kitchen. Now, I love creating a healthier version that my own kids ask for by name.

This Healthy Potato Leek Soup is everything you want: silky, savory, and satisfying, but it's made with simple, wholesome ingredients. I've swapped heavy cream for a touch of Greek yogurt and used plenty of leeks for that gentle oniony sweetness. It's the kind of meal that makes you feel good from the inside out.

Whether you're looking for a light lunch or a starter for a special dinner, this soup comes together quickly and can be dressed up or down. I hope it brings a little warmth to your table, just as it does to mine.

About the Ingredients

3 tablespoons (42g) unsalted butter

Adds richness. Substitute with olive oil for a dairy-free version.

2 large leeks, white and light green parts only, sliced (about 3 cups)

Clean thoroughly; leeks trap grit. Use a salad spinner or soak in water.

1 medium yellow onion, chopped

Adds depth. Sweet onion also works.

3 cloves garlic, minced

Fresh is best; garlic powder in a pinch (1/2 tsp).

6 cups (1.4 liters) low-sodium vegetable broth

Chicken broth works too. Low-sodium lets you control salt.

2 pounds (900g) Yukon Gold potatoes, peeled and diced into 1-inch cubes

Yukon Golds give a buttery texture. Russets also fine, but may need more cooking.

1 teaspoon salt, plus more to taste

Adjust based on broth saltiness.

1/2 teaspoon black pepper

Freshly ground for best flavor.

1/2 cup (120g) plain Greek yogurt

Adds tangy creaminess. Use dairy-free yogurt for vegan.

1 tablespoon fresh chives, chopped, for garnish

Optional; green onions also work.

Tips & Tricks

Don't skip cleaning the leeks

Slice them, then soak in a bowl of water, swish, and lift out with a slotted spoon. Repeat if gritty.

• For a smoother soup, use an immersion blender directly in the pot. Be careful not to over-blend if you like some texture.
• Taste before adding extra salt – broth and Greek yogurt add saltiness.
• If you prefer a thinner soup, add extra broth or a splash of milk when blending.

Step-by-Step Instructions

1. Melt Butter and Sauté

In a large pot or Dutch oven, melt butter over medium heat (350°F/175°C). Add leeks and onion; cook, stirring occasionally, until softened and translucent, about 8-10 minutes. The leeks should be tender but not browned.

2. Add Garlic and Season

Stir in garlic, salt, and pepper. Cook for 1 minute until fragrant.

3. Add Broth and Potatoes

Pour in vegetable broth and add diced potatoes. Increase heat to high (400°F/200°C) and bring to a boil. Then reduce heat to low (200°F/95°C), cover, and simmer until potatoes are fork-tender, about 15-20 minutes.

4. Blend Until Smooth

Remove pot from heat. Use an immersion blender to puree the soup until smooth and creamy. Alternatively, carefully transfer to a blender in batches.

5. Stir in Greek Yogurt

Whisk in Greek yogurt until fully incorporated. The soup will turn a beautiful pale yellow. Taste and adjust seasoning.

6. Serve and Garnish

Ladle into bowls and garnish with fresh chives and a swirl of extra yogurt if desired. Serve hot.

Delicious Variations

• Add a handful of fresh spinach when blending for extra greens and nutrients.
• Top with crispy bacon bits or smoked paprika for a smoky twist.
• For a vegan version, use olive oil and dairy-free yogurt.
