Potato leek soup is a comforting, creamy classic that has been cherished for generations. This old-fashioned recipe is simple, hearty, and full of flavor. Using minimal ingredients, it’s the perfect dish for a cozy meal at home. Here’s how you can prepare this delightful soup for six servings.

1. Old Fashioned Potato Leek Soup Recipe (6 Servings)

Ingredients

  • 2 tablespoons butter
  • 3 large leeks, chopped (white and light green parts only)
  • 3 cloves garlic, minced
  • 2 lbs (910 g) potatoes, peeled and cubed
  • Salt, to taste
  • Pepper, to taste
  • 6 cups (1.5 L) vegetable broth
  • 2 cups (480 mL) water
  • 2 sprigs fresh thyme
  • 1 bay leaf
  • ¼ cup (10 g) fresh chives, chopped (for garnish)
  • Hot sauce, to taste (optional)

Instructions

Prepare the base: In a large pot, melt the butter over medium heat. Add the chopped leeks and sauté until soft, about 5 minutes. Stir in the minced garlic and cook for another minute, ensuring the garlic doesn’t burn.

Add the potatoes and season: Toss in the cubed potatoes, and season with salt and pepper to taste. Stir everything together to coat the potatoes in the buttery leek mixture.

Pour in the liquids: Add the vegetable broth and water to the pot. Stir well, then add the fresh thyme sprigs and bay leaf. Bring the mixture to a boil over high heat.

Simmer until tender: Reduce the heat to a simmer and cook for 20–25 minutes, or until the potatoes are fork-tender. Remove the thyme sprigs and bay leaf from the pot.

Blend the soup: Using an immersion blender, puree the soup until smooth. Alternatively, transfer the soup in batches to a countertop blender, being careful not to overfill. Blend until creamy, then return it to the pot.

Adjust the flavor: Taste the soup and adjust the seasoning with more salt, pepper, or a dash of hot sauce if desired.

Serve and garnish: Ladle the soup into bowls and garnish with fresh chopped chives. Serve hot with crusty bread or crackers for a complete meal.

2. Tips To Perfect Potato Leek Soup

Use the right potatoes: Starchy varieties like Russets or Yukon Golds work best, as they break down nicely and create a creamy texture.

Clean the leeks thoroughly: Leeks often hide dirt between their layers. Slice them lengthwise and rinse under running water to remove all debris.

Blend carefully: If using a countertop blender, avoid overfilling it, as hot liquids can create pressure and cause spills.

Don’t skimp on seasoning: The soup’s flavor largely depends on salt and pepper. Taste as you go to achieve the perfect balance.

3. Recipe Variations

Creamy version: Add ½ cup of heavy cream or a dollop of sour cream after blending for a richer, creamier soup.

Vegan-friendly: Replace butter with olive oil and skip the cream to keep the recipe completely plant-based.

Chunky style: Instead of fully blending the soup, mash half of the potatoes with a fork to retain some texture.

Add more veggies: Include carrots, celery, or parsnips for additional flavor and nutrition.

Protein boost: Stir in cooked bacon bits, shredded chicken, or crumbled sausage for a heartier meal.

4. What To Eat With Potato Leek Soup

Potato leek soup pairs beautifully with a variety of sides. Here are some ideas to elevate your meal:

Crusty bread: A warm baguette or sourdough loaf is perfect for dipping.

Salad: A simple green salad with vinaigrette adds freshness and balance.

Cheese plate: Serve with sharp cheddar, Gruyère, or goat cheese for a delicious contrast.

Sandwiches: Grilled cheese or a turkey sandwich complements the soup’s flavors well.

Roasted vegetables: Try roasted asparagus or Brussels sprouts for a satisfying side.

5. How To Store & Reheat Leftovers

Storage: Allow the soup to cool completely before transferring it to an airtight container. Refrigerate for up to 4 days.

Freezing: Potato leek soup freezes well. Store in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating.

Reheating: Warm the soup in a pot over medium heat, stirring occasionally. Add a splash of water or broth if it’s too thick. Alternatively, reheat individual portions in the microwave, stirring every 30 seconds until hot.

Potato leek soup is a classic recipe that’s easy to customize and perfect for any season. With its creamy texture and wholesome ingredients, it’s sure to become a favorite in your home. Give it a try and enjoy the comforting flavors of this classic dish!
