You need about 15 minutes of hands-on work for this soup. The slow cooker handles the rest, and the result is a pot of tender potatoes in a creamy base that you finish with cheddar, bacon and scallions at the table.
The one step people skip is the thickener. Butter, flour, cream and sour cream get whisked together in a saucepan first, then stirred into the hot soup for a final 30 minutes. Dump the cream straight into the crock and you get a thin, watery soup instead.
This makes six bowls. It reheats well, which matters on a weeknight when you want lunch the next day too.
Step-by-Step Instructions
1. Load the slow cooker
Put the potatoes, diced onion, chicken broth, salt and pepper into the slow cooker. Stir once so the seasoning spreads out.
2. Cook until tender
Cover and cook on low for 6 hours or on high for 4 hours. The potatoes should crush easily against the side of the pot with a spoon.
3. Make the cream mixture
About 10 minutes before the potatoes finish, melt the butter in a saucepan over medium heat. Whisk in the flour and cook for about a minute, then pour in the heavy cream and whisk in the sour cream. Keep whisking until the mixture thickens slightly, 3 to 5 minutes. Do not let it boil.
4. Stir and thicken
Pour the cream mixture into the slow cooker and stir well. Cover and cook on low for another 30 minutes. The soup should coat the back of a spoon when it is ready.
5. Serve loaded
Ladle into bowls and top with shredded cheddar, crumbled bacon and chopped scallions.
Tips & Tricks
- Cut the potatoes into even 1-inch pieces. Uneven chunks mean some turn to mush while others stay firm.
- Whisk the flour into melted butter and let it bubble for about a minute before adding cream. That cooks out the raw flour taste.
- Add the cream mixture to the slow cooker, stir, and give it the full 30 minutes on low. The soup thickens as it sits.
- Taste before serving. Salt levels in broth vary, so adjust at the end rather than at the start.
Pro Tips
Variations
Loaded baked potato style
stir 1 cup of shredded cheddar into the pot during the last 5 minutes, then top with bacon and scallions as usual.
Add ham instead of bacon
dice 1 cup of cooked ham and stir it in with the cream mixture.
Vegetable broth swap
use vegetable broth in place of chicken broth for a meatless version, and skip the bacon topping.
How to Store Slow Cooker Loaded Potato Soup
Refrigerator
Keep leftovers in a sealed container in the fridge for up to 4 days. The soup thickens as it cools, so loosen it with a splash of broth or milk when reheating.
Freezer
Freezing is not ideal because cream and potatoes can separate and turn grainy. If you freeze it, do so in portions for up to 2 months and reheat gently, stirring often.
Reheating
Warm on the stovetop over low heat, stirring now and then, until it reaches a simmer. Add broth or milk a little at a time if it is too thick. Do not boil hard or the cream can split.
Frequently Asked Questions
Q: Can I leave the potato skins on?
Yes. Scrubbing them well and leaving the skins on saves time and adds texture. Peeled potatoes give a smoother soup, so it comes down to what you prefer.
Q: Why did my soup turn out thin?
Most likely the cream mixture went in without thickening first, or it was not cooked the full 30 minutes after stirring. Whisk the butter, flour, cream and sour cream until it visibly thickens, then give it the full 30-minute finish on low.
Q: Can I use half-and-half instead of heavy cream?
Yes, but the soup will be less rich and a little thinner. Keep the flour amount the same, and expect to need a bit more thickening time.
Q: How do I know the potatoes are done without a timer?
Press a piece against the side of the slow cooker with a spoon. If it crushes with no resistance, it is done. If it holds firm, add 30 minutes and check again.
Q: Can I make this on the stovetop instead?
Yes. Simmer the potatoes, onion, broth, salt and pepper in a covered pot for about 20 minutes, until tender. Then stir in the thickened cream mixture and simmer for another 10 minutes, stirring often.
