Easy Crock Pot Potato Soup – Creamy Comfort Dinner
There is nothing quite like coming home to a slow cooker full of creamy, comforting potato soup after a long day. This easy Crock Pot potato soup turns a bag of russet potatoes, a little onion, and a few pantry staples into a velvety, satisfying dinner that practically cooks itself.
The secret is a simple cornstarch or flour slurry stirred in at the end, which thickens the broth without any fussy roux or constant stirring. A splash of evaporated milk adds richness without the risk of curdling that regular milk can bring in a slow cooker.
Whether you top it with crispy bacon, sharp cheddar, and fresh chives or keep it simple with a swirl of butter, this soup is the kind of cozy, crowd-pleasing meal that earns a permanent spot in your rotation.
Why You'll Love This Recipe
About the Ingredients
3 pounds (1.36 kg) russet potatoes, peeled and cut into 1-inch cubes
Russets break down beautifully and give the creamiest texture. Yukon Golds work well too if you prefer a slightly firmer bite, and you can leave the skins on for extra fiber.
1 medium yellow onion, diced (about 1 cup / 160 g)
Yellow onion adds a sweet, mellow base flavor. If you are short on time, use 1 cup of frozen diced onions straight from the freezer with no thawing needed.
3 cloves garlic, minced
Fresh garlic gives the best flavor, but 1 teaspoon of garlic powder can stand in if that is what you have on hand. Add powder with the broth rather than at the end.
4 cups (960 ml) low-sodium chicken broth
Chicken broth brings the savory backbone. Use vegetable broth for a vegetarian version, or a 32-ounce carton of stock works perfectly here.
1 teaspoon salt, plus more to taste
Kosher salt is preferred for its clean flavor. Taste and adjust at the end since broth sodium levels vary a lot between brands.
1/2 teaspoon black pepper
Freshly cracked pepper has the most aroma. White pepper is a nice swap if you want the soup to stay pure white in color.
4 tablespoons (32 g) cornstarch whisked with 1/4 cup (60 ml) cold water
This slurry is what thickens the soup at the end. All-purpose flour whisked into cold water works too, but cornstarch gives a glossier, silkier finish.
1 can (12 ounces / 354 ml) evaporated milk
Evaporated milk stays smooth and resists curdling in the slow cooker. Half-and-half or whole milk can be used, but stir them in at the very end off the heat.
3 tablespoons (42 g) unsalted butter
Butter adds a rich, rounded finish. Salted butter is fine too, just reduce the added salt slightly and taste before seasoning.
1 cup (113 g) shredded sharp cheddar cheese, plus more for serving
Sharp cheddar gives the best flavor payoff. Shred it yourself from a block for smoother melting, since pre-shredded cheese can turn grainy.
6 slices bacon, cooked and crumbled, for topping
Bacon adds smoky crunch on top. Skip it or use turkey bacon or crispy fried onions for a lighter or meat-free version.
2 tablespoons chopped fresh chives or green onions, for garnish
Chives bring a fresh, oniony bite. Thinly sliced green onion tops are an easy substitute and hold up well in the fridge.
Tips & Tricks
Do Not Overcook the Potatoes
Cook just until fork-tender, about 6 to 7 hours on low, because potatoes that cook too long turn gluey and grainy.
Thicken at the End, Not the Start
Cornstarch loses its thickening power during long cooking, so always stir the slurry in during the last 30 minutes on high.
Keep the Dairy for Last
Evaporated milk can still separate if boiled hard, so stir it in at the end and let it heat through gently without a rolling boil.
Season in Layers
Salt the potatoes lightly at the start, then taste and adjust after the cheese and bacon go in, since both add saltiness.
Pro Tips
Step-by-Step Instructions
1. Layer the Base
Add the cubed potatoes, diced onion, minced garlic, salt, and pepper to a 6-quart slow cooker. Pour the chicken broth over everything; the liquid should just barely cover the potatoes, so add a splash of water if needed.
2. Slow Cook on Low
Cover and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the potatoes are fork-tender and pierce easily with no resistance. Do not lift the lid during the first few hours, as trapped heat is what cooks the soup evenly.
3. Mash for Texture
Use a potato masher to crush about one-third of the potatoes right in the pot, leaving the rest chunky. The mashed potatoes thicken the broth naturally and give the soup a hearty, homemade body.
4. Thicken the Soup
Whisk the cornstarch with the cold water until completely smooth, then stir it into the soup. Cover and cook on high for 25 to 30 minutes, until the broth bubbles gently at the edges and visibly thickens.
5. Add the Cream and Cheese
Reduce the slow cooker to warm or turn it off, then stir in the evaporated milk, butter, and shredded cheddar. Stir until the butter melts and the cheese is fully incorporated, about 2 to 3 minutes; the soup should look glossy and velvety.
6. Taste and Season
Taste the soup and add more salt and pepper as needed, keeping in mind the bacon and cheese will add saltiness. If it seems too thick, loosen it with a splash of warm broth or milk.
7. Serve and Top
Ladle into bowls and top with crumbled bacon, extra cheddar, and a sprinkle of chives. Serve hot with crusty bread or oyster crackers for dipping.
Delicious Variations
Loaded Baked Potato
Stir in 1/2 cup of sour cream at the end and top with extra bacon, cheddar, and green onions for a baked-potato-inspired bowl.
Cheesy Broccoli Potato
Add 2 cups of frozen broccoli florets during the last 30 minutes of cooking for a veggie-packed version the whole family will eat.
Spicy Southwest
Stir in a 4-ounce can of diced green chiles and 1 teaspoon of cumin with the broth, then finish with pepper jack cheese and a squeeze of lime.
How to Store Easy Crock Pot Potato Soup
Refrigerator
Store in an airtight container in the refrigerator for up to 4 days. The soup will thicken as it chills, so loosen it with a splash of broth or milk when reheating.
Freezer
Freeze in portions for up to 2 months, but note that dairy-based soups can separate slightly. Thaw overnight in the refrigerator and reheat gently, stirring often, for the best texture.
Reheating
Reheat on the stovetop over medium-low heat, stirring occasionally, until steaming hot but not boiling, about 5 to 7 minutes. Add a splash of milk or broth if it has thickened too much.
Frequently Asked Questions
Q: Can I put raw potatoes in the Crock Pot for potato soup?
Yes, raw cubed potatoes are exactly what you want in this recipe and they cook perfectly in the slow cooker. Cut them into even 1-inch pieces so they finish cooking at the same time.
Q: Why did my potato soup turn out gluey?
Overcooked or over-mashed potatoes release too much starch and turn gluey. Cook only until fork-tender and mash just one-third of the potatoes gently rather than blending the whole pot.
Q: Can I use milk instead of evaporated milk?
Yes, but stir whole milk or half-and-half in at the very end after turning off the heat so it does not curdle. Evaporated milk is more stable and gives a richer result in the slow cooker.
Q: How do I make Crock Pot potato soup thicker?
Whisk 1 to 2 extra tablespoons of cornstarch with cold water and stir it in during the last 30 minutes on high. You can also mash a few more potatoes for natural body.
Q: Can I make this potato soup vegetarian?
Yes, simply swap the chicken broth for vegetable broth and skip the bacon. Top with crispy fried onions or toasted sunflower seeds for crunch instead.
