Make this hearty, creamy Kielbasa Potato Soup in one pot for a simple, comforting weeknight dinner. It features smoky sausage, tender potatoes, and rich cheddar cheese.
Cook the sliced kielbasa in a large pot or Dutch oven over medium heat until lightly browned. Remove the sausage with a slotted spoon and set aside, leaving about 1 tablespoon of rendered fat in the pot.
Add the olive oil to the pot if needed. Add the chopped onion and cook until softened, about 5 minutes.
Add the minced garlic and cook for 1 minute until fragrant.
Pour in the chicken broth. Add the diced potatoes, thyme, salt, and pepper. Bring the mixture to a boil, then reduce heat, cover, and simmer for 15 minutes, or until the potatoes are tender.
Use a potato masher to lightly mash some of the potatoes against the side of the pot to slightly thicken the broth.
Stir in the heavy cream and the cooked kielbasa. Heat through gently, but do not boil after adding the cream.
Remove the pot from the heat. Gradually stir in the shredded cheddar cheese until it melts completely into the soup, creating a creamy texture.
Taste and adjust seasoning if necessary. Serve hot, garnished with fresh parsley.
Notes
For a slow cooker version, combine all ingredients except the cream and cheese in the slow cooker. Cook on low for 6-7 hours or high for 3-4 hours. Stir in the cream and cheese during the last 30 minutes of cooking.
You can substitute smoked sausage for kielbasa if needed.
Shred your own cheddar cheese for the best melting results. Pre-shredded cheese often contains anti-caking agents that affect creaminess.
