Potato Leek Creamy Classic

Featured in: Slow Cooker

This creamy French-inspired dish features tender potatoes and softened leeks slowly cooked in vegetable stock and finished with milk or cream for a rich texture. The soup is gently seasoned with garlic, bay leaf, salt, pepper, and a touch of nutmeg to deepen the flavor. An immersion blender purées the ingredients into a smooth, velvety consistency. Garnish with fresh chives, parsley, or croutons for a delightful touch. Quick and easy to prepare, it’s a nourishing option for a satisfying bowl any time.
