Ingredients You’ll Need

Each ingredient here plays a crucial role in building flavor and creaminess—the leeks bring delicate onion-like sweetness while the potatoes create that luscious, velvety base. Picking fresh leeks and the right potatoes makes all the difference, so here’s what you’ll want to shop for.

• Butter: I always use unsalted so I can control the saltiness better in the soup.
• Garlic cloves: Freshly minced garlic adds a subtle kick without overpowering the leeks.
• Leeks (white and pale green parts only): Make sure to clean these really well; they tend to hide dirt between their layers.
• Potatoes (Sebago, Russet, or Maris Piper): These varieties are starchy—perfect for a creamy texture when cooked and blended.
• Chicken or vegetable stock (low sodium): Using low sodium lets you season perfectly without the soup getting too salty.
• Heavy/thickened cream (or milk as a lighter substitute): Cream makes it indulgent, but milk works fine if you want to keep things light.
• Cooking salt/kosher salt: Adjust depending on preference and salt type.
• Black pepper: Freshly cracked is always best for that little peppery warmth.
• Bread slices for croutons: I prefer a good quality rustic bread for toasty, crunchy croutons.
• Butter or olive oil spray (for croutons): Butter gives richness, while olive oil keeps it a bit lighter.
• Chives (for garnish): They add a fresh, mild onion flavor and a pop of green color.
• Extra cream (for drizzling): Optional but adds a lovely finishing touch.

Variations

One of the best things about this Creamy Leek and Potato Soup Recipe is how flexible it is—personalizing it is part of the fun! I like switching things up depending on the season or what’s in my fridge.

• Vegetarian or Vegan: Swap out the chicken stock for vegetable stock and use coconut cream or a nut-based milk instead of heavy cream. I’ve had success with oat cream too—it keeps the soup creamy but lighter.
• Herb Boost: Adding fresh thyme or rosemary while the soup simmers introduces another depth of flavor I adore on colder days.
• Crunch Factor: For a bit more texture, try tossing in some crispy bacon bits or toasted seeds along with the croutons. It creates a nice contrast to the soup’s creaminess.
• Spice it up: A pinch of smoked paprika or cayenne pepper adds a little warmth if you like a slight kick.

How to Make Creamy Leek and Potato Soup Recipe

Step 1: Gently Sauté the Leeks and Garlic

Start with melting your butter over medium heat. Once it’s melted and shimmering, toss in the sliced leeks and minced garlic. The key here is to cook them slowly until they’re soft and fragrant—not browned—about 8 to 10 minutes. This gentle simmering brings out their sweetness and forms a flavorful base you’ll thank me for later.

Step 2: Add Potatoes and Stock, Then Simmer

Once your leeks have softened, stir in the diced potatoes and pour in your stock. Bring the whole pot up to a gentle boil, then reduce the heat to maintain a steady simmer. Let it cook uncovered for around 20-25 minutes, or until the potatoes are tender enough to pierce with a fork. This is where patience pays off—the potatoes soak up all that lovely leek flavor.

Step 3: Blend Until Smooth and Creamy

Once the potatoes are soft, it’s blending time. You can use an immersion blender straight in the pot—that’s my favorite way for less mess—or transfer the soup in batches to a blender. Puree until silky smooth, then return to the pot. Stir in the cream, and season with salt and pepper to taste. Be sure to taste as you go; sometimes you’ll want a touch more seasoning to bring it all home.

Step 4: Prepare the Croutons

While the soup is simmering, get started on the croutons. Toss your torn bread pieces with melted butter or olive oil and a pinch of salt. Spread them out on a baking tray and toast in a preheated oven at 375°F (190°C) for about 10 minutes, shaking the tray halfway through so they brown evenly. These crunchy bits are the perfect contrast to the creamy soup.

How to Serve Creamy Leek and Potato Soup Recipe

Garnishes

I love finishing this soup with a generous sprinkle of finely chopped chives for a touch of freshness. Sometimes I add a gentle swirl of extra cream for a pretty, glossy look that also ups the indulgence factor. If I’m feeling a little adventurous, a tiny drizzle of good-quality olive oil adds an unexpected fruitiness that pairs beautifully.

Side Dishes

This soup stands on its own but if you want to turn it into a meal, I often pair it with a simple green salad or crusty artisan bread. Grilled cheese sandwiches or a fresh baguette work great too, especially if you’re serving it for a cozy weeknight dinner.

Creative Ways to Present

For a dinner party, I sometimes ladle the soup into small cups or jars and top with a mini crouton and chives—cute and easy to eat while mingling. You could also sprinkle toasted pumpkin seeds or add a dollop of sour cream for a fun twist. Presentation doesn’t have to be fussy to impress!

Make Ahead and Storage

Storing Leftovers

I usually let the soup cool completely before transferring it to an airtight container. It keeps beautifully in the fridge for up to 3 days. When storing, keep the croutons separate so they don’t get soggy. It’s such a handy soup for quick lunches during the week!

Freezing

I’ve frozen this Creamy Leek and Potato Soup Recipe multiple times, and it freezes wonderfully. Just cool it fully, then pour it into freezer-safe containers or heavy-duty bags. Defrost overnight in the fridge before reheating for best texture and flavor retention. Just skip adding the cream until after reheating if you want to keep it extra fresh.

Reheating

Reheat gently on the stove over low to medium heat, stirring occasionally to prevent sticking and ensure even warmth. If the soup thickens too much, add a splash of stock or water to loosen it. I find reheating slowly really helps preserve the creamy texture—and don’t forget to stir in any extra cream last thing before serving.
