This Slow Cooker Potato Soup is SO GOOD! You’ve got to try it!

I often try to use a slow cooker for soups because you can throw all the ingredients into one pot, walk away and come back hours later to an almost finished soup. This is one of the most delicious and coziest soups I have made.


First, I did a little peeling and dicing of the potatoes and onions.

Then I threw them in a slow cooker with some chicken broth then let it all cook for hours. It was so easy! No stirring and constantly watching the pot.

Hours later, when the potatoes were almost done, I made a roux of butter and flour and added it to the soup to help thicken it up.

Stirring roux with a whisk into the slow cooker filled with diced potatoes, onions and broth.

I also added some sour cream and heavy cream and gave it a stir. After adding a little salt and pepper and stirring again, I let this yummy soup cook for 30 minutes more.

My Slow Cooker Potato Soup was tasty on its own, but I thought to myself, why not top it off with crispy bacon, shredded cheddar cheese and sliced green onions? A little extra added goodness is never a bad thing. Am I right?

Obviously, I wasn’t thinking of cutting calories when I was making this soup. I’m not going to tell you this is a low-calorie soup. It isn’t. What I will tell you is that you must try this soup. It’s a delectable, creamy, and satisfying soup. The kind of soup everyone will love. After all, what’s not to love? It’s the most creamy, delicious, coziness in a bowl.
