Ingredients

• 3 large Leeks
• 4 medium Russet potatoes
• 3 whole Garlic cloves
• 6 cups Chicken or vegetable broth
• 2 tablespoons Unsalted butter
• 1 cup Heavy cream
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 teaspoon Fresh thyme leaves
• 1 whole Bay leaf
• 2 tablespoons Chopped parsley (optional, for garnish)

Directions

Step 1

Start by preparing the leeks: trim off the dark green tops and root ends. Cut the leeks in half lengthwise and slice them into thin half-moons. Rinse the sliced leeks thoroughly in a colander to remove any grit or dirt.

Step 2

Peel the potatoes and cut them into 1-inch cubes. Set aside.

Step 3

Peel and mince the garlic cloves.

Step 4

In a large skillet over medium heat, melt the butter. Add the rinsed leeks and minced garlic, cooking until the leeks have softened and are slightly translucent, about 5 minutes.

Step 5

Transfer the cooked leeks and garlic to the slow cooker.

Step 6

Add the cubed potatoes, chicken or vegetable broth, salt, black pepper, thyme, and bay leaf to the slow cooker. Stir to combine.

Step 7

Cover the slow cooker with its lid and set it to cook on low for 6-8 hours or high for 4-5 hours. Cook until the potatoes are very tender.

Step 8

Once the soup has finished cooking, remove and discard the bay leaf.

Step 9

Use an immersion blender to puree the soup directly in the slow cooker until smooth. Alternatively, transfer the soup in batches to a blender and blend until smooth, then return it to the slow cooker.

Step 10

Stir in the heavy cream and cook for an additional 10-15 minutes on low to heat through.

Step 11

Taste the soup and adjust the seasoning with more salt or pepper, if needed.

Step 12

Ladle the soup into bowls and garnish with chopped parsley, if desired. Serve hot and enjoy!
