This creamy Crockpot Potato Leek Soup is a cozy bowl of goodness! Made with tender potatoes and sweet leeks, it’s simple to prepare and gets better as it cooks.
Honestly, my favorite part is how easy it is—just chop and toss everything in the pot. Plus, who can resist a warm soup on a chilly day? It’s like a hug in a bowl! 😊
Key Ingredients & Substitutions
Potatoes: Russet or Yukon Gold potatoes are best for this soup because they break down nicely and create that creamy texture. If you need a lighter option, try using red potatoes, but keep in mind they won’t be as creamy.
Leeks: Fresh leeks give a wonderful flavor to the soup. If leeks aren’t available, you can substitute them with green onions or even shallots. Just remember that the flavor will be a bit milder.
Broth: Using low-sodium chicken broth allows you to control the saltiness. Vegetable broth works well too, especially for a vegetarian option. You can also make your own broth if you’re feeling adventurous!
Cream: Heavy cream makes the soup rich and creamy, but you can use half-and-half or even whole milk for a lighter version. For a dairy-free option, try coconut milk—it adds a unique flavor!
How Do I Properly Clean and Prep Leeks?
Cleaning leeks can be tricky because dirt can hide between their layers. Here’s a simple way to do it:
- Cut off the dark green tops and the root ends. Discard or save the greens for stock.
- Slice the leeks down the middle and rinse well under running water or soak them in a bowl of water. This will help remove dirt and grit.
- Drain and slice the cleaned leeks as needed for the recipe.
What’s the Best Way to Puree the Soup Smoothly?
To get a smooth texture for your potato leek soup, using an immersion blender is easiest and keeps things less messy. Here’s how:
- After the soup is cooked and the potatoes are very tender, insert the immersion blender and blend until smooth.
- If you don’t have an immersion blender, carefully ladle small amounts of the soup into a regular blender. Blend each batch until smooth, then return it to the pot.
Whichever method you choose, be sure to let it cool slightly before blending hot liquids to avoid splatter.

Ingredients You’ll Need:
For the Soup:
- 4 large potatoes (such as Russet or Yukon Gold), peeled and diced
- 3 large leeks, white and light green parts only, cleaned and sliced
- 4 cups low-sodium chicken broth or vegetable broth
- 1 cup heavy cream or half-and-half
- 2 cloves garlic, minced
- 3 tablespoons unsalted butter

- Fresh parsley, chopped (for garnish)

- Optional: ½ teaspoon dried thyme or fresh thyme sprigs
How Much Time Will You Need?
This tasty Potato Leek Soup will take about 15 minutes to prep and then 6-8 hours to cook on low (or 3-4 hours on high). You’ll be rewarded with a warm, comforting bowl of soup perfect for any day!
Step-by-Step Instructions:
1. Prepare the Leeks:
Start by trimming the roots and dark green tops off the leeks. Slice the white and pale green parts and place them in a bowl of water. Gently swish them around to remove any dirt and grit, then drain them well. This will ensure your soup is clean and tasty!
2. Sauté the Leeks and Garlic:
In a skillet over medium heat, melt the butter. Add the cleaned and sliced leeks (and the chopped onion if you’re using it) to the pan. Cook them, stirring occasionally, for about 5 minutes or until they’re softened. Add the minced garlic for the last minute to keep it flavorful.
3. Combine Ingredients in the Crockpot:
Transfer the sautéed leeks and garlic into your crockpot. Now, add the diced potatoes, chicken or vegetable broth, salt, pepper, and dried thyme if you’re using it. Stir everything together so it’s nicely combined.
4. Cooking Time!
Cover the crockpot and set it to cook on low for 6-8 hours or on high for 3-4 hours. You want the potatoes to be very tender so they’ll blend smoothly into the soup.
5. Blend the Soup:
Once the cooking time is up and your kitchen smells amazing, it’s time to blend the soup. Use an immersion blender to puree the soup right in the crockpot until it’s nice and smooth. If you don’t have an immersion blender, carefully ladle portions into a blender, blend them until smooth, and then return it to the crockpot.
6. Add the Cream:
Now stir in the heavy cream or half-and-half. Let the soup warm on low for another 15-20 minutes. If you’d like, taste the soup and adjust the seasoning with more salt and pepper as needed.
7. Serve and Enjoy!
It’s time to serve your delicious soup! Ladle it into bowls, garnish each serving with freshly chopped parsley and a sprinkle of black pepper. If you want to make it a meal, serve it with some crusty bread or a roll on the side.
This creamy, hearty soup is perfect for cozying up on a chilly day or sharing with friends and family. Enjoy your delicious creation!
Can I Use Different Types of Potatoes?
Absolutely! While Russet or Yukon Gold are ideal for a creamy texture, you can also use red potatoes. Just keep in mind that they have a firmer texture and may not create quite as smooth a soup.
Can I Make This Soup Vegan?
Yes! Simply substitute the chicken broth with vegetable broth and use coconut milk or a plant-based cream in place of the heavy cream or half-and-half. Omit the butter and sauté the leeks in a splash of olive oil instead.
How Do I Store Leftover Soup?
Store any leftover soup in an airtight container in the refrigerator for up to 3 days. To reheat, warm it gently on the stove over low heat, stirring occasionally until heated through.
Can I Freeze This Potato Leek Soup?
Yes, you can freeze the soup! Allow it to cool completely before transferring it to a freezer-safe container. It can be frozen for up to 3 months. When you’re ready to enjoy it, thaw it in the fridge overnight and then reheat on the stove.
