Easy Slow Cooker Potato Leek Soup with Boursin
This creamy slow-cooker leek soup showcases leeks’ mild onion flavor, enhanced by plenty of fresh and dried herbs and with potatoes adding texture and body. Boursin is a soft, spreadable cheese, similar to whipped cream cheese, that comes in a variety of flavors. We like how the garlic-and-herb flavor enhances the overall flavor of the soup, but you can substitute sour cream. To prevent the sour cream from curdling in the hot soup, place in a small bowl and slowly stir in some of the hot broth until the mixture is smooth and creamy-looking before adding to the slow cooker.

Ingredients
-
3 pounds Yukon Gold potatoes, peeled and chopped
-
6 cups thinly sliced leeks, well rinsed, white and light green parts only
-
1 large stalk celery, finely chopped
-
4 cups reduced-sodium vegetable broth or no-chicken broth
-
2 tablespoons unsalted butter
-
3 medium cloves garlic, finely chopped
-
2 bay leaves
-
1 teaspoon finely chopped fresh thyme
-
3/4 teaspoon salt
-
1/2 teaspoon ground pepper
-
1 cup heavy cream
-
1/2 cup garlic-and-herb Boursin
-
3/4 cup seasoned croutons, roughly crumbled
-
2 tablespoons finely chopped fresh chives
-
2 tablespoons fresh dill
Method
- Combine potatoes, leeks, celery, broth, butter, garlic, bay leaves, thyme, salt and pepper in a 6-quart slow cooker; stir well. Cover and cook until the potatoes are tender, about 4 hours on High or 9 hours on Low.
- Remove and discard the bay leaves. Stir in cream and Boursin. Cover and cook on High until the cheese has melted, about 20 minutes. Using a potato masher, mash the mixture to reach desired consistency.
- Divide the soup among 8 shallow bowls. Top each with 1 1/2 tablespoons crumbled croutons, 3/4 teaspoon chives and 3/4 teaspoon dill.
