How to Make Slow Cooker Potato Leek Soup Recipe
Step 1: Sauté the Aromatics
Start by slicing the leeks and discarding the thick green pieces at their ends. In a large skillet, melt the butter over medium-high heat and add in the garlic along with those beautiful leeks. Sauté until they soften – this step brings out their natural sweetness and sets a lovely foundation for your soup.
Step 2: Assemble Your Ingredients
Once your leeks are tender, transfer them to your slow cooker. Now, peel (if you’d like) and chop those yukon gold potatoes into chunks and add them to the pot along with bay leaves, thyme, salt, and pepper. Don’t forget – these ingredients are what make this soup truly special!
Step 3: Pour in the Broth
Next, pour in that fragrant chicken broth until everything is submerged. Give it all a little stir to combine everything nicely. Close the lid on your slow cooker and set it to high for 5 hours or low for 8 hours – let those flavors meld together beautifully.
Step 4: Blend It Up
When your potatoes are soft enough to break apart easily, remove any thyme sprigs and bay leaves from the pot. Using an immersion blender (or working in batches with a food processor), blend until smooth but don’t overdo it! A few small chunks add nice texture.
Step 5: Add Cream and Garnish
Finally, stir in that luscious heavy cream for richness and blend again lightly just to combine everything. Top with freshly chopped chives before serving hot alongside crusty bread – trust me; it’s heavenly!
Enjoy every spoonful of this warm hug in a bowl!
