Kielbasa Potato Soup

This slow cooker kielbasa potato soup is one of our favorite soups to make during the fall and winter months. There are some soups that we’ll make maybe once a month, but this one hits our table at least a couple of times a month throughout the cold weather.

This delicious soup begins with a healthy dose of salty, smoky kielbasa. It’s paired with chunky potatoes, onions, carrots, and celery – all the classic soup standards. It’s all cooked slowly in a chicken broth seasoned with pepper, parsley, and garlic and made extra rich with the addition of milk, cheddar cheese soup, and parmesan cheese. All of those delicious flavors come together to create a soup that satisfies and really sticks to your ribs.

Hint: To keep your potatoes from turning brown while prepping your vegetables, add the cubed potatoes to a bowl of cold water.

Variations

If you want to personalize this slow cooker kielbasa potato soup or simply mix things up a bit, I have a few ideas that you might like.

Cream Soup – If you’re not a fan of cheese soup, use a cream soup instead. Cream of chicken, mushroom, or celery all work.

Add Parsnips – Parsnips are a great root vegetable to add to this dish. They’re a sort of spicy version of carrots.

Add Some Heat – If you like heat, feel free to add some pepper flakes to this dish for a spicy kick.

Storage

This slow cooker kielbasa potato soup will keep well in an air-tight container in the refrigerator for about four days. For longer storage, you can freeze it for up to three months.

Tips

Recipes don’t get much easier than dumping everything into a slow cooker and then walking away. That being said, there are a few things to remember that will help you make the best possible soup.

Store Potatoes in Cold Water – To prevent your potatoes from turning brown while you chop your other vegetables, place your peeled, cubed potatoes in a bowl of cold water.

Fully Dissolve the Bouillon – Be sure you fully dissolve your chicken bouillon in boiling water before adding it to the soup. You might think it can dissolve on its own, but it won’t incorporate correctly.

Serve in the Slow Cooker – Place your slow cooker vessel on a trivet on the table or counter and let everyone serve themselves. This is an especially great way to serve it at get-togethers.
