Description
A creamy and comforting potato leek soup made with tender potatoes, sautéed leeks, garlic, and scallions, blended smooth with milk and sour cream for a velvety texture.
Ingredients
- 2 lbs Russet or Yukon Gold potatoes, peeled and chopped (about 5 medium)
- 2 medium leeks, white and light green parts only, thinly sliced and well-rinsed
- 2 medium scallions, thinly sliced
- 3 cloves garlic, minced
- 3 tbsp olive oil, plus more for drizzling
- 1½ tsp kosher salt, plus more to taste
- ¼ tsp freshly ground black pepper, plus more to taste
- 4 cups low-sodium chicken or vegetable broth
- 1 cup whole milk
- ⅓ cup sour cream
- Optional garnishes: fresh scallions, cracked pepper, olive oil drizzle
Instructions
- In a large heavy-bottomed pot or Dutch oven, heat 3 tablespoons of olive oil over medium heat.
- Add the sliced leeks, scallions, and minced garlic. Sauté until fragrant and softened, about 5-7 minutes. Be careful not to brown the garlic.
- Stir in the chopped potatoes, coating them with the aromatics and oil. Cook for another 3-5 minutes, stirring occasionally.
- Pour in the chicken or vegetable broth, along with 1½ teaspoons of salt and ¼ teaspoon of black pepper. Bring the mixture to a simmer. Cover and cook until the potatoes are very tender and easily pierced with a fork, approximately 15-20 minutes.
- Remove the pot from the heat. Stir in the whole milk and sour cream.
- Using an immersion blender, carefully blend the soup until it is smooth and creamy. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth.
- Return the blended soup to the pot over low heat to warm through, but do not boil after adding milk and sour cream. Taste and adjust seasoning as needed.
- Serve hot, garnished with extra sliced scallions, freshly cracked pepper, and a drizzle of olive oil, if desired.
Notes
- Be careful not to brown the garlic during sautéing to avoid bitterness.

Ingredients to make Potato Leek Soup
Few ingredients shine brighter than fresh leeks and potatoes in a simple soup. They create layers of mild onion flavor and starchy creaminess. This blends into pure comfort. High-quality broth and dairy elevate the natural sweetness. They do so without overpowering it. Here’s what you’ll need.
- 2 lbs Russet or Yukon Gold potatoes, peeled and chopped (about 5 medium) – Provide the hearty base. They offer natural thickening for smooth consistency. Choose firm ones for best results.
- 2 medium leeks, white and light green parts only, thinly sliced and well-rinsed – Add delicate, sweet onion-like flavor when sautéed. Rinse thoroughly to remove grit.
- 2 medium scallions, thinly sliced – Bring fresh, mild bite that brightens the soup. Use both white and green parts.
- 3 cloves garlic, minced – Infuse aromatic depth without dominating. Mince finely for even cooking.
- 3 tbsp olive oil, plus more for drizzling – Serve as sauté base for flavor infusion. Extra adds glossy finish.
- 1½ tsp kosher salt, plus more to taste – Season the broth to enhance vegetable flavors. Adjust to taste at the end.
- ¼ tsp freshly ground black pepper, plus more to taste – Add subtle warmth and balance. Freshly ground gives best potency.
- 4 cups low-sodium chicken or vegetable broth – Form the liquid base. Vegetable keeps it vegetarian-friendly.
- 1 cup whole milk – Contribute to creamy body. It avoids curdling if added off heat.
- ⅓ cup sour cream – Give tangy richness for velvety texture. Stir in at the end for smoothness.
- Optional garnishes: fresh scallions, cracked pepper, olive oil drizzle
How to Make Potato Leek Soup
Step 1: Heat the oil and sauté aromatics
In a large heavy-bottomed pot or Dutch oven, warm 3 tablespoons of olive oil over medium heat. Add the thinly sliced leeks, scallions, and minced garlic. Then sauté until fragrant and softened, about 5-7 minutes. Take care not to brown the garlic. This prevents any bitterness.
Step 2: Add and cook the potatoes
Stir in the chopped potatoes. Coat them evenly with the aromatics and oil. Continue cooking for another 3-5 minutes. Stir occasionally to build flavor in the base.
Step 3: Simmer with broth
Pour in the low-sodium chicken or vegetable broth. Add 1½ teaspoons of kosher salt and ¼ teaspoon of black pepper. Bring the mixture to a simmer. Cover the pot. Cook until potatoes are very tender. They should pierce easily with a fork, about 15-20 minutes.
Step 4: Incorporate dairy
Remove the pot from the heat. Stir in the whole milk and sour cream until fully combined. This adds the creamy element. It avoids risking curdling from high heat.
Step 5: Blend the soup
Using an immersion blender, carefully puree the soup right in the pot. Blend until smooth and creamy. If using a standard blender, transfer in batches. Blend until velvety. Then return to the pot.
Step 6: Warm and season
Place the pot over low heat. Gently warm the blended soup through. But avoid boiling to keep the dairy smooth. Taste and adjust with more salt or pepper as needed. Serve hot.
Pro Tips for Success
- Avoid Browning Garlic: Sauté gently over medium heat. This keeps flavors sweet. It prevents bitter notes in your potato leek soup.
- Rinse Leeks Thoroughly: Slice and soak in water. This removes hidden sand. It ensures a clean, grit-free texture.
- Simmer Until Fork-Tender: Test potatoes at 15 minutes. Avoid undercooking. This can lead to a grainy blend.
- Add Dairy Off Heat: Stir in milk and sour cream after simmering. This maintains creaminess without separation.
How to Serve Potato Leek Soup
Garnishes
I like to finish each bowl with fresh sliced scallions. They add a bright, herby contrast. This brings crunch against the smooth base. A light drizzle of olive oil adds glossy sheen. It offers subtle richness too. Cracked black pepper gives gentle spice. It wakes up the flavors. These simple touches make the soup feel elegant. Yet it’s effortless.
Side Dishes
Pair it with crusty artisan bread. This lets you sop up every creamy drop. It creates a satisfying meal on its own. A crisp green salad with vinaigrette cuts through the richness. It adds freshness to balance the cozy warmth. For heartier appetites, try roasted root vegetables. They provide an earthy complement. But they don’t overwhelm the main dish.
Creative Ways to Present
Spoon the soup into warmed shallow bowls. This highlights its velvety golden hue. Add a swirl of extra sour cream for visual appeal. For family dinners, serve family-style in a rustic tureen. This encourages sharing. On casual nights, ladle into mugs. It’s an easy, sipable option. And it fits right into a busy routine.
Make Ahead and Storage
Storing Leftovers
I portion any extra potato leek soup into airtight containers. I keep it in the fridge. It stays fresh for up to four days. This makes it ideal for quick weekday lunches. It doesn’t lose smooth texture. Just cover tightly. This preserves the delicate flavors.
Freezing
For longer storage, cool the soup completely first. Then transfer to freezer-safe bags or containers. Flatten them for easy space-saving. It freezes well for up to three months. Most creaminess remains upon thawing. Label with the date. This helps track freshness.
Reheating
Gently reheat on the stovetop over low heat. Stir occasionally to avoid scorching the dairy base. In the microwave, use medium power. Do short bursts. Cover with a damp paper towel. This prevents drying out. Either way, it warms back to comforting perfection. And it takes just a few minutes.
