Kielbasa Potato Soup
As I was preparing this soup Greg was like, “I don’t know what you’re cooking in there but it smells amazing!” Not only did it smell wonderful it tasted wonderful too. We all loved this one and went back for seconds. It’s the perfect soup to make on a cold, dark wintry night. Enjoy!
Ingredients/Substitution Ideas
- Olive oil–or canola oil, avocado oil, vegetable oil
- Kielbasa–or smoked sausage
- Onion–yellow or white
- Chicken broth–or water and Better than Bouillon chicken base
- Carrot
- Celery
- Russet potatoes–or red potatoes
- Garlic cloves
- Red pepper flakes
- Dried parsley
- Half and half–or ¼ cup of heavy cream and ¼ cup milk
- Pepper jack cheese
- Cheddar cheese–I used sharp
Steps
Turn Instant Pot to sauté setting. When display says HOT add in the oil and swirl around. Add in the kielbasa and brown until both sides have color. Stir in the onion and sauté for 4 minutes.


Pour in the broth and scrape bottom of pot so that nothing is sticking. Turn off Instant Pot.
Add in the carrot, celery, potatoes, garlic, red pepper and parsley.

Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set SOUP button to 3 minutes. When time is up let pot sit for 5 minutes and then move valve to venting. Remove the lid.

Temper the half and half by stirring a cup of hot broth into it and then stirring the mixture into the pot.

Stir in the cheeses. Taste test, salt and pepper to taste. Ladle into bowls and serve.


Notes/Tips
- Serve with crusty bread or a hunk of cornbread with honey butter.
- If you want a thicker soup, mash a few potato cubes against the side of the pot before adding the dairy.
- Always temper the half and half to prevent the dairy from separating.
- Taste before salting since kielbasa and cheese both add salt.
- This recipe is gluten free.
- I used my 6 quart Instant Pot*. You can also make this in a 3 or 8 quart pot.
- Store leftovers in an airtight container* in the refrigerator for up to 4 days or in the freezer for up to 3 months.
- Another recipe you can make with pepper jack cheese is Instant Pot Disney Potatoes.

Honestly I wasn’t sure about this recipe. However, I had all the ingredients on hand so I took a chance. Wow! So glad I did! It was so good, I’m adding it to my go to list. I did add more carrots and celery. Thanks Karen for your hard work creating recipes for us. It keeps me happy in the kitchen without grumbling about cooking.❤️
thank you so much. I love that you took a chance and that it paid off! Extra carrots and celery sound perfect, and knowing this keeps you happy in the kitchen (without the grumbling 😉) means more to me than you know. ❤️
One carrot and one celery stalk is not very much in proportion to the sausage and potatoes. Are the carrot and celery just for flavoring. Would it be okay to add more carrot and celery?
you can add more of anything to your liking cuz I would
yes, just for flavoring and yes you can definitely add more!
