Ingredients You’ll Need for Slow Cooker Potato Leek Soup
- 4 large leeks, cleaned and sliced
- 4 medium potatoes, peeled and diced
- 4 cups vegetable broth
- 1 cup heavy cream (optional)
- 2 tablespoons olive oil or butter
- Salt and pepper to taste
- Chives for garnish (optional)
Let’s Make It Together
-
In your slow cooker, combine the sliced leeks, diced potatoes, and vegetable broth. The earthy scent of the leeks will fill your kitchen, making you feel right at home.
-
Add in the olive oil or butter for that creamy richness, and season your mixture with salt and pepper to taste.
-
Cover the slow cooker and set it to cook on low for 6-8 hours or on high for 4-5 hours. You want the potatoes to be tender, which is the perfect cue that your soup is ready for the next step.
-
Once the cooking time is up and your home is filled with the most inviting aromas, grab an immersion blender. Purée the soup to your desired consistency, whether you prefer it silky smooth or with a bit of texture remaining.
-
If you’re feeling indulgent (who wouldn’t?), stir in the heavy cream at this point, and adjust the seasoning if needed.
-
Serve the soup hot, garnished with fresh chives if desired. The touch of green not only brightens the soup but adds a lovely flavor that balances the creaminess beautifully.
Fun Ways to Customize It
-
Add Some Zest: Consider stirring in a splash of lemon juice or zest for a bright twist that complements the creamy base.
-
Herbs and Spices: Try adding thyme, rosemary, or even a pinch of nutmeg for an aromatic layer of flavor that will make your kitchen smell divine.
-
Top it Off: For a crunchy contrast, serve your soup with crispy turkey bacon, crunchy croutons, or even some toasted pumpkin seeds for a delightful crunch.
-
Vegetable Boost: Toss in some chopped carrots or celery at the beginning for added nutrition and a pop of color.
