Ingredients You’ll Need

These ingredients come together to create a rich, flavorful soup that’s both creamy and fresh-tasting. Knowing which potato and leek parts to use really makes a difference here—and I’ll share my best tips for picking the right ones!

• Butter: I always use unsalted so I can control the seasoning, but whatever you have works.
• Garlic cloves: Fresh and finely minced to infuse the soup with a lovely subtle garlicky aroma.
• Leeks: Use only the white and pale green parts—they’re sweeter and softer, perfect for the soup’s base.
• Potatoes: Choose high-starch varieties like Russet or Sebago—they break down beautifully to give you that creamy finish.
• Chicken or vegetable stock: Low sodium is best so you can adjust salt to your taste along the way.
• Cream: Heavy cream or thickened cream adds that luscious richness; you can swap milk, but it won’t be quite as silky.
• Cooking salt and black pepper: Essential for seasoning just right.
• Bread for croutons: I use thick slices from a rustic loaf to make the crispiest, most buttery croutons ever.
• Melted butter or olive oil spray: For coating the croutons before baking, that golden crisp is everything!
• Chives: Finely chopped, they add a fresh, oniony kick right at the end.

Variations

One of the things I love about this Creamy Leek Potato Soup with Croutons Recipe is how easy it is to tweak based on what you have or what you’re craving—feel free to get creative!

• Make it vegan: Swap out butter for plant-based margarine and use a rich vegetable stock with coconut cream instead of dairy; it still turns out deliciously creamy.
• Add herbs: I sometimes throw in fresh thyme or rosemary while simmering for a fragrant twist that keeps things interesting.
• Spicy kick: If you love a little heat, a pinch of smoked paprika or cayenne stirred in at the end wakes the soup right up.
• Cheesy upgrade: Some grated Gruyère or sharp cheddar melted into the soup right before serving is a real crowd-pleaser.

How to Make Creamy Leek Potato Soup with Croutons Recipe

Step 1: Sauté Garlic and Leeks to Sweet Perfection

Start by melting butter gently in a large pot over medium heat. Once it’s bubbly, add your finely minced garlic and sliced leeks. Cook them slowly for about 7 minutes until the leeks become soft and sweet without browning. This step is where the flavor builds—don’t rush it! Stir occasionally so nothing sticks or burns.

Step 2: Simmer Potatoes in Stock Until Tender

Next, toss in the cubed potatoes and pour in your chicken or vegetable stock. Turn the heat up to bring everything to a gentle simmer. Once bubbling, cover with a lid and lower the heat so it simmers quietly for about 25 minutes, or until the potatoes are so tender they almost fall apart when poked with a fork. This slow simmer lets all the flavors marry beautifully.

Step 3: Puree Just Enough for Silky Soup

Turn off the heat and grab your stick blender. Blend the soup carefully until it’s just smooth—resist the urge to over-puree! I learned the hard way that too much blending turns the soup gluey because of the starches in the potatoes. If you don’t have a stick blender, mash the potatoes by hand first, then pulse a little in a regular blender.

Step 4: Season and Stir Through Cream

Season the soup with salt and pepper to your liking, then stir in the cream until it’s luxuriously smooth and rich. This is where the soup really comes alive. Taste and adjust seasoning if you want a little more salt or black pepper punch.

Step 5: Bake Your Croutons to Crispy Perfection

Preheat your oven to 180°C/350°F. Toss your rustic bread pieces with melted butter or a spray of olive oil, and spread them on a baking sheet. Bake for about 5 minutes or until they’re golden and crisp. While still warm, sprinkle a pinch of salt over the top—this salty crunch is the perfect partner to your creamy soup.

Step 6: Serve with Garnishes and Enjoy!

Ladle your creamy leek potato soup into bowls, drizzle with an extra swirl of cream, sprinkle over chopped chives, and scatter the warm buttery croutons on top. Trust me, the contrast between creamy and crunchy is everything you didn’t realize you needed in a soup.

How to Serve Creamy Leek Potato Soup with Croutons Recipe

Garnishes

I usually garnish with a swirl of cream right before serving—that little touch makes it look gorgeous and adds extra smoothness. Freshly chopped chives are a must for me; their welcome sharpness brightens the soup perfectly. Sometimes I add a few cracked black peppercorns for a little texture and pop of flavor.

Side Dishes

This soup pairs beautifully with a crisp green salad or a simple charcuterie board if you’re entertaining. For a heartier meal, I love serving it alongside crusty sourdough or even a grilled cheese sandwich—comfort food heaven!

Creative Ways to Present

For special occasions, I sometimes serve the soup in mini bread bowls or rustic mugs, topped with a single chive stalk as a playful garnish. Layered with a drizzle of truffle oil or crispy pancetta bits adds a touch of luxury that guests rave about.

Make Ahead and Storage

Storing Leftovers

I store leftover soup in airtight containers in the fridge for up to 3 days. Because it’s cream-based, I give it a good stir before reheating to bring everything back together. It holds up really well and tastes just as comforting later in the week.

Freezing

You can freeze this soup, but I recommend leaving out the cream if you plan to freeze it. Freeze the soup base separately in portions, then add cream when reheating for the freshest texture. This way, you avoid any separation or graininess that cream can cause when frozen.

Reheating

Reheat gently on the stove over low to medium heat to avoid scorching and separation. Stir frequently and add a splash of stock or cream if it feels too thick. Avoid microwaving at high power as it can cause curdling.
