Ingredients

Scale

2 tablespoons olive oil (or coconut oil)

4 medium potatoes, peeled and diced (Yukon gold or russet)
4 cups vegetable broth (low-sodium if preferred)

Instructions

Prepare the Leeks: Slice off the roots and dark green tops. Cut leeks lengthwise, rinse well to remove dirt, and slice into thin pieces.
Sauté for Flavor (Optional): In a skillet, heat olive oil and sauté leeks and garlic for 5 minutes until fragrant. This step boosts flavor, but you can skip it if short on time.
Load the Slow Cooker: Add leeks, potatoes, vegetable broth, bay leaf, thyme, salt, and pepper to the slow cooker.
Cook: Cover and cook on low for 6–7 hours or high for 3–4 hours, until potatoes are fork-tender.
Blend: Remove the bay leaf. Use an immersion blender to puree the soup until smooth. For a chunkier texture, blend only half the mixture.
Finish: Stir in coconut milk or cashew cream if using. Taste and adjust seasoning.
Serve: Ladle into bowls, garnish with fresh parsley or chives, and enjoy with warm crusty bread.

Notes

For a rustic style, leave part of the soup chunky instead of blending completely. Add a handful of spinach or kale in the last 10 minutes for extra nutrients. Leftovers keep well in the fridge for up to 4 days or can be frozen for up to 3 months.
