Ingredients
Potatoes and leeks slow cooked to perfection, blended with a generous amount of cream.
For the Soup
- 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 Slow Cooker Potato Leek Soup Recipe
Step 1: Prepare the Leeks
Slice the leeks, discarding the thick green pieces at the ends. In a large skillet, melt the butter over medium-high heat. Add the minced garlic and sliced leeks to the skillet. Cook until the leeks are softened, about 5-7 minutes.
Step 2: Combine Ingredients in Slow Cooker
Add the softened leeks and garlic mixture to your slow cooker. Peel the yukon gold potatoes if desired and chop them into chunks. Add them to the slow cooker along with the bay leaves, thyme, salt, and black pepper.
Step 3: Add Chicken Broth
Pour in 7 cups of chicken broth over all ingredients in the slow cooker. Securely close the lid.
Step 4: Cook
Set your slow cooker on high for 5 hours or low for 8 hours. Allow it to work its magic until the potatoes are tender.
Step 5: Blend and Serve
Once cooked, remove bay leaves and thyme sprigs if using fresh ones. Using an immersion blender, blend until smooth but be careful not to over-blend; you want some texture! If using a regular blender or food processor, blend in small batches. Stir in heavy cream and blend lightly again. Garnish with chopped chives before serving hot with crusty bread.
