Ingredients

This recipe makes 6-8 servings.

• For the Soup Base:
• 2 tablespoons unsalted butter or olive oil
• 3 medium leeks, white and light green parts only, thinly sliced and thoroughly rinsed
• 1 medium yellow onion, chopped
• 4 cloves garlic, minced
• 2 pounds Yukon Gold or Russet potatoes, peeled and cut into 1-inch cubes
• 6 cups vegetable broth (low sodium preferred)
• 1 teaspoon dried thyme
• 1 bay leaf
• 1 teaspoon salt (or to taste)
• ½ teaspoon black pepper (or to taste)
• For Creaminess (optional, for finishing):
• ½ cup heavy cream or half-and-half
• For Garnish (optional):
• Fresh chives, chopped
• Crispy bacon bits
• Croutons

Step-by-Step Instructions

1. Step 1: Prepare Your Vegetables

   Start by preparing your leeks. Trim off the dark green tops and the root end. Slice the white and light green parts lengthwise, then thinly slice them into half-moons. Make sure to rinse them very well under cold water to remove any hidden dirt or sand. Peel and chop your onion, mince the garlic, and then peel and cube your potatoes into roughly 1-inch pieces. This uniform size helps them cook evenly.

   Small tip: Leeks can hold a lot of grit! After slicing, place them in a bowl of cold water and swish them around. The dirt will sink to the bottom, and you can scoop out the clean leeks.

2. Step 2: Sauté the Aromatics

   In a large skillet, melt the butter or heat the olive oil over medium heat. Add the chopped leeks and onion. Sauté for about 8-10 minutes, stirring occasionally, until they are softened and translucent. This step is crucial for developing a deep, sweet flavor in your soup. Stir in the minced garlic during the last minute of cooking until fragrant.

3. Step 3: Combine in Slow Cooker

   Carefully transfer the sautéed leeks, onion, and garlic into your slow cooker insert. Add the cubed potatoes, vegetable broth, dried thyme, bay leaf, salt, and black pepper. Give everything a gentle stir to combine all the ingredients. Ensure the potatoes are mostly submerged in the broth.

4. Step 4: Cook to Perfection

   Place the lid on your slow cooker. Cook on LOW for 4 hours or on HIGH for 2.5 hours. The soup is ready when the potatoes are fork-tender and easily mashable. Avoid peeking too often, as this releases heat and can extend the cooking time.

5. Step 5: Blend for Creaminess

   Once the potatoes are tender, remove the bay leaf from the slow cooker. For a creamy soup, use an immersion blender directly in the pot to blend the soup until it reaches your desired consistency. If you prefer a chunkier soup, blend only about half of the soup, leaving some potato pieces intact. Alternatively, you can carefully transfer portions of the soup to a regular blender (blend in batches, filling only halfway, and vent the lid) and then return it to the slow cooker.

   Small tip: If using a regular blender, be very careful with hot liquids. Always hold the lid down firmly with a kitchen towel and start blending on a low speed.

6. Step 6: Finish and Serve

   Stir in the heavy cream or half-and-half (if using) until well combined. Taste the soup and adjust the seasoning with more salt and pepper if needed. Ladle the warm soup into bowls. Garnish with fresh chopped chives, crispy bacon bits, or crunchy croutons for extra flavor and texture. Serve immediately and enjoy!

Tips & Variations

• Gluten-Free Option: This soup is naturally gluten-free! Just double-check your vegetable broth label to ensure it’s certified gluten-free.
• Vegan/Vegetarian Option: To make this soup completely vegan, use olive oil instead of butter for sautéing. For the creamy finish, swap the heavy cream for full-fat coconut milk (for a subtle coconut flavor) or a plant-based unsweetened milk alternative like cashew or soy milk.
• Add More Vegetables or Protein: Feel free to toss in other vegetables like diced carrots or celery along with the potatoes for added nutrients. For a heartier meal, stir in some cooked, shredded chicken or diced ham during the last 30 minutes of cooking.
• Spicy Version: For a little kick, add a pinch of red pepper flakes along with the thyme and bay leaf. A dash of cayenne pepper at the end also works wonderfully.
• Cheesy Twist: Stir in ½ cup of shredded sharp cheddar cheese or Gruyere cheese during the last few minutes of cooking, after blending, for a rich and cheesy variation.

Storage Tips

Leftover Slow Cooker Potato Leek Soup can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, this soup freezes beautifully! If you plan to freeze it, it’s best to omit adding the heavy cream until you reheat it, as dairy can sometimes separate upon thawing. Freeze in freezer-safe containers for up to 3 months. To reheat, thaw overnight in the fridge (if frozen), then gently warm on the stovetop over medium-low heat or in the microwave. Stir in the cream during reheating if you previously omitted it.
