- Variety of potatoes: While russets are traditional, using Yukon gold potatoes will give your soup a buttery flavor. Feel free to mix different varieties for an interesting taste and texture.
- Blend to perfection: For a smoother consistency, use an immersion blender to puree the soup directly in the slow cooker once it’s cooked. This allows for a velvety texture without the need to transfer hot liquid to a blender.

Instructions (step-by-step with cooking tips)
- Prep your ingredients: Start by thoroughly washing the leeks. Slice them into thin rounds, ensuring to rinse to remove any grit. Peel the russet potatoes and cut them into bite-sized cubes.
- Layer your slow cooker: Place the diced potatoes and sliced leeks into the slow cooker. Sprinkle the minced garlic on top for an added layer of flavor.
- Add your broth: Pour in the vegetable broth. This is where the soup begins to take shape, creating a savory base for all your ingredients to meld together.
