3. 2 garlic cloves, minced – Enhances the overall flavor with a hint of pungent warmth.
4. 4 cups vegetable broth – Serves as the liquid base for the soup; opt for low-sodium broth if preferred.

6. 1 teaspoon kosher salt – Helps bring out the flavors of the soup.
7. 1 bay leaf – Adds a subtle herbal note that deepens the soup's complexity.
8. 2 sprigs of fresh thyme – Infuses a fragrant, earthy aroma into the soup.
9. Freshly chopped chives and black pepper (for garnish) – Provides color and an extra layer of flavor when serving.

These ingredients will yield a hearty, flavorful soup perfect for a cold evening.

Substitutions and Variations

If you want to modify the classic recipe or accommodate dietary preferences, here are a few substitution and variation ideas:

• Dairy-Free Option: While this recipe is naturally dairy-free, you can also finish the soup with a splash of coconut milk for added creaminess without the dairy.
• Add Cream: For a richer texture, stir in a half-cup of heavy cream or crème fraîche at the end of cooking.
• Substitute Leeks: If you can’t find leeks, use onions or shallots as a substitute. While the flavor will differ slightly, you’ll still get a delicious result.
• Herb Variations: Swap out thyme with rosemary or parsley for a different flavor profile.
• Spice it Up: If you like a bit of heat, sprinkle in red pepper flakes or cayenne powder when sautéing the garlic.
• Meat Lovers’ Version: Add crispy bacon or pancetta to the soup for a smoky, savory twist.
• Vegan-Friendly: The recipe is naturally vegan as long as you use vegetable broth. You can also add nutritional yeast for a cheesy, umami flavor without any animal products.

Step-by-Step Cooking Instructions

Step 1: Prepare the Leeks

Leeks tend to hold a lot of dirt between their layers, so be sure to wash them thoroughly before cooking. Trim off the dark green tops and the roots. Slice the white and light green parts of the leeks in half lengthwise, then chop into thin slices. Place the leeks in a colander and rinse them well under cold water, separating the layers to remove any dirt or grit.

Step 2: Sauté the Leeks and Garlic

In a large pot or Dutch oven, heat the extra-virgin olive oil over medium heat. Add the leeks and cook, stirring occasionally, for about 6-8 minutes, until they become soft and translucent. Be careful not to let them brown. Add the minced garlic and sauté for an additional minute until fragrant.

Step 3: Add Potatoes and Broth

Once the leeks and garlic are fragrant, add the diced potatoes, vegetable broth, bay leaf, thyme sprigs, and kosher salt to the pot. Stir to combine all the ingredients.

Step 4: Simmer the Soup

Bring the mixture to a boil, then reduce the heat to a gentle simmer. Let the soup cook for about 20-25 minutes, or until the potatoes are soft and easily pierced with a fork. The flavors will meld together, creating a deliciously fragrant base for the soup.

Step 5: Remove Herbs and Blend

Once the potatoes are tender, remove the bay leaf and thyme sprigs from the soup. Use an immersion blender to blend the soup until it’s smooth and creamy. If you prefer a chunkier texture, blend only half of the soup and leave the rest as-is. You can also use a traditional blender by transferring the soup in batches.

Step 6: Adjust Consistency and Seasoning

If the soup is too thick, add a bit more vegetable broth to thin it out to your desired consistency. Taste and adjust the seasoning, adding more salt or black pepper as needed.

How to Cook Potato Leek Soup: A Step-by-Step Guide

To sum up, here’s a quick guide on how to cook potato leek soup:

1. Clean and chop leeks, ensuring all dirt is removed.
2. Sauté leeks and garlic in olive oil until soft and fragrant.
3. Add potatoes, broth, herbs, and salt, then bring to a boil and simmer until the potatoes are tender.
4. Blend the soup until smooth, adjusting the thickness and seasoning as needed.
5. Garnish with chives and black pepper for a finishing touch.

Common Mistakes to Avoid

• Skipping the Leek Cleaning Process: Leeks often contain hidden dirt. Be sure to wash them thoroughly, as skipping this step can lead to unpleasant grit in your soup.
• Overcooking the Leeks: Cook the leeks slowly and avoid browning them, as overcooking can cause bitterness.
• Using the Wrong Potatoes: Waxy potatoes like red potatoes may not blend as smoothly as Yukon Golds or Russets, resulting in a less creamy soup.
• Not Blending Properly: To achieve the perfect texture, use an immersion blender or blend the soup in batches to avoid splattering hot soup.
• Over-Seasoning: Always taste the soup before adding extra salt or seasoning, as some broths can be salty already.
