Ingredient Notes

Russet potatoes are ideal for this Crockpot Potato Soup because they break down slightly during cooking, helping to thicken the broth naturally. Yukon Gold potatoes also work well and hold their shape a bit more. Low-sodium chicken or vegetable broth allows you to control the salt level – avoid salted broth to keep the seasoning balanced. Sharp cheddar cheese adds a bold flavor without needing to use a large amount. For a milder taste, use mild cheddar or a blend of Monterey Jack. Heavy cream gives the soup its luxuriously creamy finish; you can substitute half-and-half for a lighter version. Cornstarch mixed with cold water creates a quick slurry that thickens the soup at the end without lumps. Fresh chives add a mild oniony pop and a touch of color; green onions are a good alternative.

How to Make Crockpot Potato Soup

Start by prepping the vegetables: peel and dice the russet potatoes into ½-inch cubes, finely chop the onion, and mince the garlic. Add everything – including the broth, salt, and pepper – to a 6-quart slow cooker. Cover and cook on low for 6 to 8 hours until the potatoes are very tender. Once done, use an immersion blender to partially blend the soup (or mash some potatoes against the side of the pot) for that perfect mix of creamy and chunky. Stir in the butter until melted. In a small bowl, whisk together cornstarch and cold water to form a slurry, then pour it into the slow cooker along with the heavy cream and shredded cheddar. Stir well, cover, and cook on low for another 20 to 30 minutes, until the soup thickens and the cheese melts completely. Taste and adjust seasoning. Serve hot, garnished with fresh chives.

Tips for the Best Crockpot Potato Soup

  • Don't over-blend. Leave some potato chunks for a satisfying texture – you want a rustic, hearty soup, not a purée.
  • Add the dairy at the end. Stirring in the cream and cheese after the potatoes are fully cooked prevents curdling and keeps the soup silky.
  • Adjust thickness to your liking. If the soup is too thick after adding the slurry, stir in a little extra warm broth or milk. If it's too thin, let it cook uncovered for 10 to 15 minutes or add more cornstarch slurry (mix 1 tablespoon cornstarch with 1 tablespoon water).
  • Season gradually. Potatoes absorb salt, so taste before serving and add more salt or pepper in small increments.
  • Use a 6-quart or larger slow cooker. This recipe fills about half to two-thirds of the pot, allowing room for stirring and for the soup to bubble gently.

Make Ahead and Storage

Let the Crockpot Potato Soup cool completely, then transfer to an airtight container and refrigerate for up to 4 days. Reheat on the stovetop over medium-low heat, stirring occasionally, or in the microwave. If the soup has thickened after chilling, stir in a splash of broth or milk while reheating. To freeze, portion the cooled soup into freezer-safe containers or bags, leaving 1 inch of headroom. Freeze for up to 3 months. Thaw overnight in the refrigerator, then reheat gently. Note that the dairy may separate slightly after freezing, but brisk stirring will bring it back together. For the best texture, eat leftovers within 1 to 2 days if refrigerated after freezer thawing.

What to Serve With Crockpot Potato Soup

This hearty soup is a meal on its own, but it pairs beautifully with crusty bread or a side salad for a complete lunch. Try serving it with a classic grilled cheese sandwich (try sharp cheddar on sourdough) for the ultimate comfort combo. Roasted vegetables, like broccoli or asparagus, also make a great side. For a lighter option, a crisp green salad with a tangy vinaigrette cuts through the richness of the soup.

  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons unsalted butter
  • 1 cup heavy cream
  • 2 cups shredded sharp cheddar cheese
  • 3 tablespoons cornstarch
  • 3 tablespoons cold water

Instructions

1

Prepare Vegetables

Peel and dice the russet potatoes into 1/2-inch cubes. Finely chop the onion and mince the garlic. Set aside.

2

Combine and Cook

Add the potatoes, onion, garlic, broth, salt, and pepper to the slow cooker. Stir, then cover and cook on low for 6 to 8 hours, until the potatoes are very tender when pierced with a fork.

3

Partially Blend Soup

Use an immersion blender to blend about half the soup, leaving some potato chunks for texture. Alternatively, mash some of the potatoes against the side of the pot with a potato masher. Stir in the butter until melted.

4

Add Dairy and Cheese

In a small bowl, whisk together the cornstarch and cold water to form a slurry. Pour the slurry into the slow cooker, then add the heavy cream and shredded cheddar cheese. Stir well.

5

Finish Cooking

Cover and cook on low for an additional 20 to 30 minutes, stirring occasionally, until the soup has thickened and the cheese is fully melted. Taste and adjust salt and pepper if needed.

6

Serve and Garnish

Ladle the soup into bowls and top with fresh chopped chives. Serve hot.

Notes

  • For a dairy-free version, use full-fat coconut milk instead of heavy cream and a dairy-free shredded cheese blend. The soup will have a slightly different flavor but remains creamy.
  • To thicken the soup without cornstarch, mash the potatoes more thoroughly or stir in instant potato flakes (2 to 3 tablespoons) at the end.
  • The soup freezes well for up to 3 months, but the dairy may separate upon thawing. Reheat gently on the stovetop, stirring in a splash of broth or cream to restore the creamy texture.
