Crock Pot Potato Leek Soup Ingredients
- 2 large leeks, sliced
- 3 Tbsp salted butter
- 2 cloves garlic, minced
- 3 lbs Yukon gold potatoes
- 7 cups chicken broth
- 2 bay leaves
- 3 sprigs fresh thyme, or 1 tsp dried leaf thyme (not ground)
- 1 1/2 tsp salt
- 1/2 tsp black pepper
- 1 1/2 cups heavy cream
- Fresh chives, chopped (garnish)
How To Make Crock Pot Potato Leek Soup
- Sauté the leeks and garlic: Slice the leeks (discarding tough green ends). In a skillet, cook them with butter and garlic over medium-high heat until softened.
- Add ingredients to the slow cooker: Transfer the cooked leeks to a crock pot. Add peeled potatoes, bay leaves, thyme, salt, pepper, and chicken broth.
- Slow cook the soup: Cover and cook on high for 5 hours or low for 8 hours.
- Blend the soup: Remove bay leaves and thyme sprigs (if using fresh). Blend the soup carefully with an immersion blender, food processor, or blender in small batches. Do not over-blend.
- Add cream and finish: Stir in the heavy cream and blend lightly. Serve hot, topped with chopped chives and crusty bread on the side.

Recipe Tips
- Can I use vegetable broth instead? Yes, substitute chicken broth with vegetable broth for a vegetarian version.
- Do I need to peel the potatoes? Peeling is optional, but recommended for a smoother texture.
- How do I clean leeks properly? Slice them first and rinse under water to remove dirt hidden between layers.
- What if I don’t have an immersion blender? Use a food processor or blender, but work in small batches and be careful with hot liquids.
- Can I freeze this soup? Yes, just cool it completely before freezing and leave out the cream until reheating.

How To Store Potato Leek Soup
Refrigerate: Store leftovers in an airtight container in the fridge for up to 4 days.
Freeze: Let soup cool completely, then freeze without the cream for up to 3 months. Add cream after reheating.

FAQs
Can I use milk instead of heavy cream?
Yes, but the soup will be less rich. Whole milk or half-and-half are better than skim.
Why does my soup taste bland?
Make sure to season well and don’t skip the garlic and herbs—they add depth of flavor.
Can I use other potatoes?
Yes, but Yukon golds provide a naturally creamy texture and buttery flavor.
Is this gluten-free?
Yes, as long as all your ingredients (like broth) are certified gluten-free.
How to make it dairy-free?
Use dairy-free butter and substitute heavy cream with coconut milk or a plant-based alternative.
