Slow Cooker Leek And Potato Soup Recipe

Tender potatoes and flavorful leeks are blended up to a creamy and dreamy perfection to make this amazing Potato Leek Soup. Also called potage parmentier, this soup makes for a perfect light lunch or works great as a starter to a fabulous dinner.

One of the joys of using a slow cooker for this particular soup recipe is the depth of flavor you achieve. As the ingredients simmer together over several hours, they meld in harmony, deepening the soup’s character. Plus, the convenience factor is hard to beat. Just set it up, go about your day, and return to a warm, ready meal. And, lemme tell you – this soup is rich, a bit creamy, a bit chunky, a whole lot of wonderful, and is also great chilled! The chilled version of it is called Vichyssoise. So fancy, right? The flavor, the texture, and everything all together is like getting a hug from a soup bowl.

Why You’ll Love This Soup

• Versatility in Serving: Serve the soup warm with crusty bread on a cold day, or chill it for a refreshing summer appetizer. You can also play around with toppings: consider a sprinkle of crispy bacon, a dollop of sour cream, or even some grated cheddar.
• Meal Prep Friendly: This soup is a meal prepper’s dream! It stores beautifully in the refrigerator for up to a week, and its flavors continue to meld and intensify over time. If you’re looking to stretch it out further, it freezes wonderfully, too.
• Vegetarian Delight: While many soups rely on chicken or beef broth for their base, this one celebrates the richness of vegetables alone, making it a perfect option for vegetarians. And for our vegan friends, you can easily omit the butter and heavy cream or substitute them with plant-based alternatives.

How To Make Leek and Potato Soup In The Slow Cooker

I want to call this a back-to-basics recipe because it’s very simple and easygoing, and you might already have all the ingredients hiding in the pantry. The best part is that you can prep this in the morning and leave it to cook for the whole day.By the way, you only need carrots, celery, garlic, leeks, potatoes, fresh thyme, salt, pepper, and butter. AND a Slow Cooker.

1. Cut the potatoes and the leeks. Leeks may need to be washed before cutting because dirt likes to hide in places you can’t see. Just cut off the dark green part, then cut the leeks in half lengthwise, and rinse under cold water. Pat dry with paper towels and chop them up.
2. Put potatoes and leeks in the slow cooker and set aside.
3. Combine sliced carrots and celery in a skillet and sauté for 4 minutes; stir in some garlic and transfer it all to the slow cooker.
4. Stir in vegetable broth; add fresh thyme sprigs and butter.
5. Close with the lid and cook on LOW for 6 to 8 hours, or until potatoes are very tender. You can also cook it on HIGH for 4 to 5 hours.
6. When done, blend the soup with an immersion blender. If you only have a traditional blender, blend in batches. I also advise not to blend it at high speed; pulse it so that you have more control of the texture in the end. The finishing touch should involve some heavy cream – totally optional but totally necessary. 😉

Tips For Perfect Leek And Potato Soup

• Cleaning Leeks: Leeks can trap a lot of dirt between their layers. To clean, slice off the dark green parts, cut the white and light green parts in half lengthwise, and rinse thoroughly under running water, fanning out the layers.
• Consistent Sizing: Ensure that your potatoes are cut into roughly even sizes. This helps them cook uniformly.
• Seasoning: Potatoes tend to absorb a lot of salt, so always taste and adjust your seasoning before serving. A splash of lemon juice or white wine vinegar can also brighten the flavors.
• Smooth or Chunky: If you like a chunkier texture, only blend a portion of the soup, leaving some potato and leek pieces whole. Conversely, for a smoother soup, blend thoroughly.
• Protein Boost: Add white beans, lentils, or even diced chicken for a protein-packed version.
• Spicy Kick: Add a finely chopped chili pepper or a dash of cayenne pepper to introduce a warm heat to your soup.
• Cheesy Delight: Stir in some grated cheddar, gruyère, or your cheese of choice for a richer, cheesier soup.

Serving Suggestions

• Serve This Soup As A Main Course. When serving soup as a main, be generous with the portion size. Offering a larger bowl will ensure it feels like the meal’s centerpiece. Also, accompany the soup with substantial sides: crusty focaccia bread, a slice of quiche, a stuffed roll, or a mixed green goddess salad. Top your soup with flavorful garnishes. This could be fresh herbs, grated cheese, a swirl of cream, toasted seeds, or even a sprinkle of spice.
• Serve As a Side Dish. If you want to make the Potato Leek Soup a starter or a complement to a main course, consider serving this Roasted Chicken as a main meal or my Churrasco Steak. For a vegetarian spin, serve it with my Tomato Tart or my Creamy Parmesan Baked Zucchini.

Storage

• Leftovers: Store soup in an airtight container and keep in the fridge for up to 3 days.
• To freeze: Potato Leek Soup can be frozen for 3 months, but don’t add the cream if you plan to freeze it.
