Ingredients List

Creamy potato leek soup begins with a short, simple list of ingredients. You likely have most of them on hand, which is part of what makes this such a fantastic, last-minute dinner idea. The key is choosing the right potatoes and cleaning the leeks properly for the best flavor.

• 3 tablespoons unsalted butter
• 3 large leeks, white and light green parts only, thoroughly cleaned and sliced
• 3 cloves garlic, minced
• 2 pounds Yukon Gold potatoes, peeled and diced (about 4-5 medium)
• 4 cups low-sodium chicken broth (or vegetable broth for a vegetarian version)
• 1 teaspoon dried thyme (or 3-4 sprigs fresh thyme)
• 1 bay leaf
• 1 cup heavy cream or half-and-half
• Salt and freshly ground black pepper, to taste
• Optional garnishes: Chopped fresh chives, crispy bacon bits, a drizzle of good olive oil, or a sprinkle of sharp cheddar cheese.

Smart Swaps & Dietary Notes:

• Dairy-Free: Swap the butter for olive oil and use full-fat canned coconut milk instead of heavy cream. It adds a lovely, subtle sweetness.
• Vegetarian: Use a rich vegetable broth. I find mushroom or “no-chicken” vegetable broths work best for depth.
• Lighter Option: Substitute the heavy cream with whole milk or even evaporated milk for a lighter, yet still creamy, texture.
• Potatoes: Yukon Golds are my first choice for their buttery texture and natural creaminess, but Russets will also work well; just know the soup might be a bit starchier.

Timing

One of the joys of this creamy potato leek soup is how quickly it comes together for something that tastes like it simmered all afternoon.

• Prep Time: 15 minutes (mostly cleaning and chopping)
• Cook Time: 30 minutes
• Total Time: 45 minutes

That’s about 20% faster than many traditional blended soup recipes that require roasting vegetables first. From fridge to bowl in under an hour is my kind of weeknight victory.

Step-by-Step Instructions

Follow these simple steps for a perfectly smooth and flavorful creamy potato leek soup every single time.

1. Clean and Prep the Leeks. This is the most important step! Leeks grow in sandy soil, and grit can hide between their layers. Slice the leeks first, then submerge them in a large bowl of cold water. Swirl them around with your hands—the sand will sink to the bottom. Scoop the clean leeks out with a slotted spoon or your hands. Pat them dry with a clean kitchen towel.

2. Sauté the Aromatics. In a large Dutch oven or heavy-bottomed pot, melt the butter over medium heat. Add the cleaned, sliced leeks. Cook, stirring occasionally, for about 8-10 minutes until they are very soft and wilted but not browned. This slow cooking builds a sweet, mellow base for your soup. Add the minced garlic and cook for just one more minute until fragrant.

3. Build the Soup Base. Add the diced potatoes, chicken broth, dried thyme, and bay leaf to the pot. Increase the heat to bring the mixture to a boil, then immediately reduce to a steady simmer. Cover the pot and let it cook for 15-20 minutes, or until the potatoes are fork-tender and easily mashed against the side of the pot.

4. Blend to Creamy Perfection. Remove the bay leaf. Using an immersion blender, carefully blend the soup right in the pot until completely smooth. If you’re using a standard blender, work in batches, filling the blender only halfway and holding the lid firmly with a towel to prevent hot soup explosions. Pro Tip: For an ultra-silky texture, you can pass the blended soup through a fine-mesh sieve, but I usually skip this—it’s wonderfully creamy as is.

5. Finish with Cream. Return the smooth soup to the pot if you used a blender. Stir in the heavy cream and warm the soup through over low heat for another 3-5 minutes. Do not let it boil after adding the cream. Season generously with salt and pepper. Taste and adjust—the salt will really make the flavors of this creamy potato leek soup sing.

Equipment Needed

You don’t need any fancy gadgets to make this creamy potato leek soup. A few trusty kitchen staples will do the job perfectly.

• A Large Dutch Oven or Heavy-Bottomed Pot: Essential for even heating and preventing the leeks from burning.
• A Good Chef’s Knife and Cutting Board: For prepping the vegetables.
• Immersion Blender (or Standard Blender): The key to that signature velvety texture. An immersion blender is my favorite for easy cleanup.
• Ladle and Measuring Cups.
• Fine-Mesh Sieve (Optional): For an extra-smooth finish.

Why You’ll Love This Recipe

This creamy potato leek soup has earned a permanent spot in my dinner rotation for so many reasons.

1. It’s the Ultimate Comfort Food. This soup is cozy in a bowl. It’s rich, warming, and deeply satisfying—the perfect antidote to a chilly day or a stressful one.
2. Incredibly Simple to Make. With no roux to make and no fancy techniques, this is one of the most straightforward easy soup recipes you’ll find. It’s foolproof.
3. Family-Friendly & Crowd-Pleasing. Its mild, creamy flavor is a hit with all ages. It’s a gentle way to introduce the lovely, onion-like flavor of leeks.

Healthier Alternatives for the Recipe

You can easily tailor this creamy potato leek soup to fit different dietary needs without sacrificing an ounce of flavor.

• Dairy-Free & Vegan: Use olive oil to sauté and a full-fat coconut milk for the cream. The result is luxuriously creamy with a hint of tropical sweetness that works surprisingly well.
• Lower-Carb / Keto: Replace half the potatoes with cauliflower florets. You’ll still get a creamy texture and body, with a significant reduction in carbs.
• Higher-Protein: Stir in a can of rinsed white beans (like cannellini) before blending. They’ll make the soup even creamier and add a protein and fiber boost. For a heartier, meat-based protein, consider starting with a base of homemade stock from one of our chicken soup recipes.
• Lighter Version: Use half-and-half or whole milk instead of heavy cream, and swap half the butter for broth when sautéing the leeks.

Serving Suggestions

A bowl of this creamy potato leek soup is a meal all on its own, but a few thoughtful additions can turn it into a feast.

• The Perfect Toppings: A sprinkle of crispy, crumbled bacon or pancetta adds salty crunch. Fresh chives or a drizzle of truffle oil elevates it for guests. A handful of sharp cheddar or a dollop of sour cream never hurts.
• The Ideal Side: A thick slice of crusty, buttered sourdough bread for dipping is non-negotiable in my house. A simple side salad with a bright vinaigrette cuts through the richness beautifully.
• For a Heartier Meal: Serve it alongside a grilled cheese sandwich for the ultimate comfort food duo, or add a scoop of cooked, shredded chicken to the bowl for extra protein.
• Seasonal Twist: In the fall, add a pinch of nutmeg with the thyme. For a spring version, finish the soup with a handful of fresh peas or asparagus tips after blending.

Common Mistakes to Avoid

A few small missteps can change your soup’s texture and flavor. Here’s how to avoid them.

1. Not Cleaning Leeks Thoroughly: Gritty soup is the worst. Take the extra two minutes to wash your sliced leeks in a water bath. Trust me.
2. Rushing the Sauté: Don’t crank the heat to brown the leeks quickly. Cooking them slowly and gently in the butter is what develops their signature sweet, mellow flavor, which is the soul of this creamy potato leek soup.
3. Underseasoning: Potatoes and cream need salt. Season in layers: a pinch when sautéing the leeks, and then be generous when you finish the soup with cream. Taste and adjust until the flavors pop.
4. Boiling After Adding Cream: High heat can cause the dairy to “break” or separate, giving the soup a grainy look. Always warm it through gently on low heat.
5. Over-blending Potatoes: If you use a standard blender and run it too long, the potatoes can become gluey. Blend just until smooth.

Storing Tips for the Recipe

This soup is a dream for leftovers and meal prep.

• Refrigerator: Cool the soup completely and store it in an airtight container for up to 4 days. The flavors meld and improve.
• Freezer: This creamy potato leek soup freezes exceptionally well. Portion it into freezer-safe bags or containers, leaving an inch for expansion. It will keep for up to 3 months. Thaw overnight in the fridge.
• Reheating: Gently reheat on the stove over low heat, stirring occasionally. If it seems too thick after storage, thin it with a little broth or water until it reaches your desired consistency. Avoid the microwave on high power, as it can cause the cream to separate.
