This Crock Pot Potato Soup is the kind of recipe that earns a permanent spot in your rotation: you dump potatoes, onion, and broth into the slow cooker in the morning, walk away, and come home to a pot of velvety, bacon-topped comfort food. The potatoes cook down until they collapse at the touch of a spoon, and a last-minute swirl of cream and cheddar turns the whole thing silky and rich.

The trick to a soup that tastes slow-simmered but never gluey is mashing only about half the potatoes, leaving the rest in tender chunks so every spoonful has texture. Real crumbled bacon, sharp cheddar, and a hit of garlic keep it from tasting flat, and a handful of green onions at the end wakes everything up.
Serve it in bread bowls, with a grilled cheese on the side, or straight from a mug on a cold night. It freezes beautifully, reheats without breaking, and makes enough to feed a hungry family with leftovers for lunch.
Why You'll Love This Recipe
About the Ingredients
6 slices (about 6 oz / 170g) bacon, chopped
Use thick-cut bacon for meatier crumbles, or swap in 1 cup of diced ham for a smokier, leaner soup.
1 medium yellow onion (about 1 cup / 160g), diced
Sweet onion or leek (white part only) works well here; avoid red onion, which turns the broth an unappealing pink.
3 lbs (1.4kg) russet potatoes, peeled and cut into 1-inch cubes
Russets break down into the creamiest base; Yukon Golds hold their shape more, so mash a little extra if you use them.
4 cups (960ml) low-sodium chicken broth
Vegetable broth makes it vegetarian; if using full-sodium broth, skip the added salt until the end.
3 cloves garlic, minced
Fresh garlic is best, but 1 teaspoon of garlic paste from a tube works in a pinch.
1 teaspoon kosher salt, plus more to taste
Diamond Crystal kosher salt measures differently than Morton; taste before adding the final pinch.
1/2 teaspoon black pepper
Freshly cracked pepper has far more aroma than pre-ground; add a pinch more at the table.
1 can (12 oz / 354ml) evaporated milk
Evaporated milk stays smooth in the slow cooker where heavy cream can curdle; whole milk works if you add it at the very end.
2 cups (8 oz / 225g) sharp cheddar cheese, shredded
Shred it yourself from a block; pre-shredded cheese is coated in starch and clumps instead of melting smoothly.
1/4 cup (15g) sliced green onions, for serving
Chives or a spoonful of sour cream are classic stand-ins if you are out of green onions.
Tips & Tricks
Do not add the dairy early
Stir in evaporated milk and cheese only in the last 30 minutes on Low, or the soup can curdle and turn grainy.
Cut the potatoes evenly
Uniform 1-inch cubes cook at the same rate, so you avoid a pot of mush with hard chunks in the middle.
Mash, do not blend
Mash about half the potatoes right in the pot with a masher; an immersion blender will turn the whole batch into paste.
Cook the bacon first
Browning the bacon and using a spoonful of the drippings to soften the onion adds a smoky depth the slow cooker cannot create on its own.
Pro Tips
Step-by-Step Instructions
1. Crisp the bacon
Cook the chopped bacon in a skillet over medium heat (about 350F / 175C) for 8-10 minutes, until deep golden brown and crisp. Transfer to a paper towel, reserving 1 tablespoon of drippings.
2. Soften the onion
Add the onion to the reserved drippings and cook over medium heat (about 350F / 175C) for 4-5 minutes, until translucent and soft at the edges. Stir in the garlic and cook 30 seconds, until fragrant.
3. Load the slow cooker
Scrape the onion mixture into a 6-quart slow cooker. Add the potatoes, broth, salt, and pepper, then stir so the potatoes are mostly submerged.
4. Slow cook
Cover and cook on Low for 6-7 hours or on High for 3-4 hours, until the potatoes are fork-tender and crush easily against the side of the pot.
5. Mash for texture
Mash roughly half the potatoes with a potato masher right in the pot, leaving plenty of tender chunks. The broth should look creamy and slightly thickened, like loose gravy.
6. Add the dairy
Stir in the evaporated milk and shredded cheddar, cover, and cook on Low for 25-30 minutes, until the cheese is fully melted and the soup is gently bubbling at the edges. Do not let it boil hard.
7. Season and serve
Taste and adjust salt and pepper. Ladle into bowls and top with the crisp bacon and green onions.
Delicious Variations
Loaded Baked Potato
Top each bowl with sour cream, extra cheddar, and a sprinkle of chives for a fully loaded baked potato in soup form.
Cheesy Broccoli Potato
Stir in 2 cups of small broccoli florets during the last 45 minutes on High for a greener, heartier bowl.
Spicy Southwest
Add a 4 oz can of diced green chiles and 1 teaspoon of cumin with the broth, then finish with pepper jack instead of cheddar.
How to Store Crock Pot Potato Soup
Refrigerator
Store in an airtight container in the refrigerator for up to 4 days; the soup thickens as it chills, so loosen with a splash of broth when reheating.
Freezer
Freeze in portions for up to 3 months; dairy-based soups can separate slightly, so whisk well during reheating and add a splash of milk.
Reheating
Reheat gently on the stovetop over medium-low heat (about 300F / 150C) for 8-10 minutes, stirring often, or microwave in 1-minute bursts until steaming.
Frequently Asked Questions
Q: Can I put raw potatoes in the Crock Pot for potato soup?
Yes, raw peeled and cubed potatoes go straight into the slow cooker and cook perfectly in 3-4 hours on High or 6-7 hours on Low. Just cut them into even 1-inch pieces so they finish at the same time.
Q: Why did my potato soup turn out gluey?
Over-mashing or blending releases too much starch and makes the soup gluey. Mash only about half the potatoes with a hand masher and never use an immersion blender for this recipe.
Q: Can I use frozen potatoes or hash browns instead?
Yes, 6 cups of frozen diced potatoes can replace the fresh russets, and you can skip the peeling step entirely. Add them frozen and cook on Low for 5-6 hours, since they release more water, so reduce the broth by 1/2 cup.
Q: How do I keep the dairy from curdling in the slow cooker?
Add the evaporated milk and cheese only during the last 30 minutes on Low, and never let the soup come to a rolling boil after they go in. Evaporated milk is more stable than regular cream, which is why this recipe uses it.
Q: Can I make this potato soup in the Instant Pot instead?
Yes, pressure cook the potatoes, onion, and broth on High for 10 minutes with a 10-minute natural release, then stir in the dairy on Saute. Use the same ingredient amounts and mash to your preferred texture.
