Crock Pot Potato Soup

Pin it

Introduction

This slow-cooker potato soup comes together in one pot and cooks hands-off for hours, making it ideal for meal prep or a set-it-and-forget-it weeknight dinner. The combination of potatoes, onions, celery, and chicken broth creates a savory base, while evaporated milk adds richness without requiring cream. You can serve it chunky or blend it smooth depending on your preference.

Recipe Details

• Prep Time: 20 minutes
• Cook Time: 3 to 11 hours (depending on heat setting)
• Total Time: 3 hours 20 minutes to 11 hours 20 minutes
• Servings: 8

Ingredients

• 5 large potatoes, diced
• 3 medium onions, diced
• 5 cups water
• 1 tablespoon parsley
• 1 stalk celery, diced
• 1 teaspoon salt
• Black pepper, to taste
• 4 cups chicken broth
• 4 to 5 tablespoons butter
• 1 (13-ounce) can evaporated milk

Instructions

1. In a slow cooker, combine potatoes, onions, water, parsley, celery, salt, pepper, chicken broth and butter.
2. Cook until done — on low heat, 9 to 11 hours, or on high heat, 3 to 4 hours.
3. When done, add milk and reheat.
4. Serve plain or use an immersion blender/put mixture in blender for a smoother soup.
5. Reheat if necessary.

Variations

Loaded potato soup: Stir in shredded cheddar cheese, crispy smoked turkey strips, and fresh chives just before serving for a heartier, more indulgent version.

Roasted vegetable version: Replace one onion with diced roasted garlic, and add diced roasted carrots alongside the potatoes for sweetness and deeper flavor.

Herb-forward soup: Double the parsley and add 1 teaspoon of dried thyme and 1 teaspoon of dried sage in the initial cooking step for an earthier profile.

Potato and mushroom: Dice 8 ounces of cremini or button mushrooms and add them with the potatoes for umami depth and meatier texture.

Blended base with chunky finish: Blend half the cooked soup until smooth, then stir it back into the pot with the remaining chunks for a creamy yet textured result.

Tips for Success

Don’t skip dicing evenly: Cut potatoes and onions to roughly the same size so they cook at the same rate and won’t leave you with mushy onions and firm potato chunks.

Add the milk at the end: Evaporated milk can curdle if simmered for hours; adding it right before serving keeps the soup smooth and creamy.

Taste before blending: Season the soup to your preference before pureeing—it’s harder to adjust seasoning once blended, and flavors can mute slightly.

Use an immersion blender for easy cleanup: If you prefer a smoother soup, an immersion blender lets you blend directly in the slow cooker, avoiding extra dishes.

Plan for heat setting based on your schedule: Low heat (9–11 hours) works well for overnight or all-day cooking; high heat (3–4 hours) is better for same-day prep.

Storage and Reheating

Store the cooled soup in an airtight container in the refrigerator for up to 4 days. You can also freeze it in freezer-safe containers or bags for up to 3 months (leave 1 inch of headspace if freezing in containers to allow for expansion).

To reheat, thaw overnight in the refrigerator if frozen, then warm on the stovetop over medium heat, stirring occasionally, until heated through (5–10 minutes for chilled soup, 15–20 minutes for thawed frozen soup). You can also reheat directly in the slow cooker on low heat for 1–2 hours. If the soup seems too thick after freezing and thawing, thin it with a splash of chicken broth or water.

FAQ

Can I prep the vegetables the night before?

Yes. Dice the potatoes, onions, and celery, store them in separate airtight containers in the refrigerator, and add them to the slow cooker in the morning. Potatoes may brown slightly, but this won’t affect the final soup.

What’s the difference between cooking on low versus high?

Low heat (9–11 hours) produces a gentler cook with slightly more tender vegetables and blended flavors, while high heat (3–4 hours) is faster but can result in a less cohesive broth. Choose based on your schedule.

Can I use fresh potatoes instead of russets?

Yes, though cooking times may vary slightly. Red potatoes hold their shape better if you prefer chunks; russets break down more easily for a creamier result when blended.

How do I know when the soup is done?

Potatoes should be fork-tender and easily break apart. If you’re blending, texture matters less, but if serving chunky, you want pieces that hold together but yield without resistance.
