Ingredients

For the Soup:

• 2 tablespoons unsalted butter: For sautéing the leeks and building the flavor base of the soup.
• 4 large leeks: Thoroughly cleaned and sliced. Leeks add a mild, sweet onion flavor to the soup.
• 4 medium potatoes: Peeled and diced. Russet potatoes work best for a creamy texture, but you can also use Yukon Gold potatoes for a slightly richer flavor.
• 4 cups vegetable broth or chicken broth: The broth provides the liquid base and depth of flavor. Use homemade or store-bought, depending on what you have available.
• 1 cup heavy cream: Adds richness and creaminess to the soup. For a lighter version, you can substitute with half-and-half or a plant-based alternative.
• 1 teaspoon dried thyme: For a hint of earthy, aromatic flavor. Fresh thyme can also be used for a more vibrant taste.
• Salt and freshly ground black pepper: To taste, enhancing the natural flavors of the vegetables and broth.
• 1 tablespoon olive oil: For sautéing the leeks if you prefer a lighter fat option.
• 1 bay leaf: Optional, but it adds a subtle depth of flavor to the soup.
• Fresh chives or parsley: For garnish, adding a burst of color and a light, herbal touch.

Optional Garnishes:

• Crispy bacon: Crumbled, for added crunch and smokiness.
• Grated cheese: A sprinkle of sharp cheddar or Parmesan for extra flavor.
• Croutons: For added texture and crunch.

First Step: PREPARE THE LEEKS AND POTATOES

1. Clean the Leeks: Leeks often have dirt trapped between their layers, so it’s essential to clean them thoroughly. Cut off the root end and the dark green top (you can save the dark green tops for making vegetable stock). Slice the remaining part of the leek (the white and light green portion) lengthwise, then cut it into half-moon slices. Place the sliced leeks in a large bowl of water, swishing them around to release any dirt. Drain and set aside.
2. Prepare the Potatoes: Peel the potatoes (if desired) and cut them into roughly equal-sized cubes. This ensures they cook evenly and break down into a creamy consistency during blending.

Second Step: COOK THE LEEKS

1. Sauté the Leeks: In a large soup pot or Dutch oven, heat the butter or olive oil over medium heat. Once hot, add the sliced leeks and sauté for 5-7 minutes, stirring occasionally, until they become soft and translucent. The leeks should be fragrant but not browned.
2. Add Garlic (Optional): For extra flavor, you can add 2 cloves of minced garlic to the leeks during the last minute of sautéing, cooking until fragrant.

Third Step: COOK THE POTATOES AND BROTH

1. Add the Potatoes: To the softened leeks, add the diced potatoes and stir to combine. This allows the potatoes to absorb some of the flavor from the leeks and butter.
2. Add Broth and Seasoning: Pour in the vegetable or chicken broth and stir in the dried thyme, bay leaf (if using), and a pinch of salt and pepper. Bring the soup to a simmer, then reduce the heat to low. Let it cook for 20-25 minutes, or until the potatoes are fork-tender and easily mashable.

Fourth Step: BLEND THE SOUP

1. Blend the Soup: Once the potatoes are tender, remove the bay leaf (if used) and either use an immersion blender directly in the pot or transfer the soup in batches to a countertop blender. Blend until the soup is completely smooth and creamy. If you prefer a chunkier texture, blend only half of the soup and leave the rest as is.
2. Adjust Consistency: If the soup is too thick, add a little more broth or water until it reaches your desired consistency.

Fifth Step: ADD CREAM AND SEASONING

1. Stir in the Cream: Once blended, return the soup to low heat and stir in the heavy cream. Let the soup warm through, allowing the cream to meld with the soup.
2. Taste and Adjust: Taste the soup and adjust the seasoning with more salt, pepper, or thyme as needed. If you like a tangy kick, you can add a squeeze of lemon juice or a splash of white wine vinegar.

Final Step: GARNISH AND SERVE

1. Serve the Soup: Ladle the soup into bowls and garnish with your choice of toppings, such as crispy bacon, grated cheese, or fresh herbs like parsley or chives.
2. Enjoy: Serve the soup warm with a side of crusty bread for dipping and enjoy the velvety, rich flavors of this comforting dish.

How to Serve Potato Leek Soup

Potato Leek Soup is versatile and can be served in various ways depending on the occasion:

1. As a Hearty Meal

Serve this soup as a main dish, especially with a side of freshly baked bread, a salad, or a light sandwich. It’s perfect for lunch or dinner and can be paired with a crisp white wine or a light beer for a complete meal.

2. As a Starter for a Formal Dinner

Potato Leek Soup makes a great first course for a special dinner or holiday meal. It’s elegant yet humble, providing a warm, welcoming start to your feast. Pair it with a white wine like Chardonnay or Sauvignon Blanc for a refined touch.

3. Perfect for Meal Prep

This soup stores beautifully in the fridge and can be made in advance, making it an excellent choice for meal prepping. The flavors improve as it sits, and it’s easy to reheat for a quick lunch or dinner during the week.

4. Pair with a Side Salad

For a lighter meal, pair Potato Leek Soup with a fresh salad, such as a mixed green salad with a tangy vinaigrette or a classic Caesar salad. The crisp freshness of the salad balances the rich creaminess of the soup.

Recipe Variations

Potato Leek Soup is incredibly adaptable, and there are plenty of ways to customize the recipe to suit your taste preferences or dietary needs.

1. Make it Vegan

To make the soup vegan, simply swap the butter for olive oil or another plant-based fat, use vegetable broth, and replace the cream with coconut cream or a plant-based cream alternative. You can also add a splash of non-dairy milk (like almond or oat milk) to achieve a creamy texture.

2. Add Extra Vegetables

If you want to add more nutrients or flavors, consider adding other vegetables, such as celery, carrots, or parsnips. These can be sautéed with the leeks and added to the soup base for a heartier version.

3. Spice it Up

For a bit of heat, try adding a pinch of cayenne pepper or red pepper flakes while the soup is simmering. You can also experiment with different herbs, such as rosemary, sage, or dill, to add complexity to the flavor profile.

4. Add Protein

For a more filling soup , you can add cooked bacon, sausage, or shredded chicken. This adds extra flavor and makes the soup even more substantial as a meal.

5. Make it Gluten-Free

This recipe is naturally gluten-free, but always check your broth to ensure it’s gluten-free if you have sensitivities.

Tips for Perfect Potato Leek Soup

1. Clean the Leeks Thoroughly: Leeks often have sand and dirt trapped in their layers, so be sure to wash them well before using them in the soup.
2. Use a Starchy Potato: Russet potatoes work best in this recipe because they break down and create a creamy texture. Avoid waxy potatoes, like red or new potatoes, as they won’t create the same velvety consistency.
3. Blend the Soup Well: For a silky-smooth texture, make sure to blend the soup until it’s completely smooth. An immersion blender is ideal, but a countertop blender works just as well.
4. Don’t Overcook the Potatoes: While you want the potatoes to be soft, overcooking them may cause them to break down too much and lose their texture. Keep an eye on them while they simmer.
