How to Make Slow Cooker Potato Leek Soup (Step-by-Step)

This Slow Cooker Potato Leek Soup Recipe is all about easy, approachable steps. Nothing fancy. Nothing stressful.

Step 1: Soften the Leeks

Slice your leeks and give them a good rinse (they like to hide dirt—classic leek behavior). Melt the butter in a large skillet over medium-high heat, add the leeks and garlic, and cook until they’re soft and fragrant. Your kitchen will already start smelling amazing.

Step 2: Add Everything to the Slow Cooker

Transfer the softened leeks and garlic to your crock pot. Add the potatoes, bay leaves, thyme, salt, and pepper. Pour in the chicken broth, give it a gentle stir, and pop the lid on.

Step 3: Let the Slow Cooker Work Its Magic

Cook on HIGH for 5 hours or LOW for 8 hours, until the potatoes are fork-tender and practically begging to be blended.

Step 4: Blend Carefully

Remove the bay leaves and thyme sprigs. Using an immersion blender, blend the soup until smooth—but don’t overdo it. If you’re using a blender or food processor, work in small batches and blend just until creamy.

Step 5: Make It Creamy

Stir in the heavy cream and blend just a little more. Taste and adjust seasoning if needed. Ladle into bowls, sprinkle with chives, and serve hot with crusty bread.

My Best Tips for the Creamiest Soup

• Don’t over-blend – Over-blending potatoes can make soup gummy. Stop while it’s still silky.
• Too thick? Add a splash of broth or milk. Too thin? Let it cook uncovered for 15–20 minutes.
• Want extra richness? A small pat of butter stirred in at the end works wonders.
• No immersion blender? A regular blender works fine—just blend in batches and be careful with hot soup.

If your soup looks thicker than expected, don’t panic. That’s not a problem—that’s comfort waiting to happen.

A Little Kitchen Story From Me
