Ingredients You’ll Need

Ingredients
Baby gold potatoes: About 1.5 lb. Creamy and flavorful; if unavailable, use cubed Yukon Gold potatoes.
Kielbasa: 14 oz, sliced into coins. Look for smoked kielbasa in the deli or refrigerated sausage section.
Canned corn: 15 oz, drained. Frozen corn can be used instead—no need to thaw if you prefer it that way.
Carrots: 8 oz (about 2 cups), sliced. Baby carrots halved or large carrots cut into coins both work.
Onion: 1 medium yellow or white onion, diced.
Beef broth: 4 cups. Use store-bought or homemade beef stock for depth of flavor.
Dijon mustard: 1 teaspoon for a subtle tang and depth.
Seasonings: 1/2 teaspoon each salt, black pepper, and garlic powder (adjust to taste).
Milk: 2 cups, added near the end for creaminess. Use 2% or whole milk; half-and-half can make the soup richer.
Sour cream: 1/2 cup to add tang and help thicken the broth.
Cheddar cheese: 8 oz shredded, stirred in at the end for richness. Freshly shredded melts best but pre-shredded is fine.
Equipment
Cutting board and knife: For chopping vegetables and slicing the kielbasa.
Slow cooker: For hands-off cooking—cook on LOW for 6–8 hours or HIGH for 3–4 hours.
Measuring cups and spoons: To measure liquids and seasonings.
Stirring spoon or spatula: Sturdy enough to stir the thick soup.
Grater (optional): If you prefer to shred your own cheddar.
How to Make Kielbasa Potato Soup
1. Prepare the ingredients
Slice or dice the potatoes, carrots, onion, and kielbasa. Add them to the slow cooker along with the drained corn.

2. Combine and slow cook
Add the beef broth, Dijon mustard, salt, pepper, and garlic powder. Stir to combine. Cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until potatoes and carrots are tender.

3. Add milk
Stir in the milk, increase the slow cooker to HIGH, and cook for 15–30 minutes to warm through and combine flavors.

4. Finish with sour cream and cheese
Stir in the sour cream and shredded cheddar until the soup is smooth and slightly thickened. Turn off the slow cooker and serve hot.

Recipe Success Tips
- To thicken: Whisk 3 tablespoons cornstarch into the cold milk before adding it to the slow cooker, then heat on HIGH until the soup thickens.
- Adjust seasoning: Beef broth and kielbasa vary in saltiness. After adding the sour cream and cheese, taste and add more salt, pepper, or garlic powder if needed.
- Make ahead: Combine everything except milk, sour cream, and cheese in a covered container and refrigerate overnight. Transfer to the slow cooker when ready to cook.
- Variations: Stir in spinach or kale for greens, add hot sauce or red pepper flakes for heat, or swap in white cheddar or parmesan for a different cheese profile.

Stovetop Directions
If you prefer stovetop or don’t have a slow cooker, follow these steps:
- Brown the kielbasa: Heat 1 tablespoon olive oil in a large pot or Dutch oven over medium heat. Add sliced kielbasa and cook 4–5 minutes until browned.
- Add remaining ingredients: Stir in the broth, potatoes, corn, carrots, onion, Dijon, salt, pepper, and garlic powder.
- Simmer: Bring to a low simmer, then reduce heat and cook about 30 minutes until vegetables are tender.
- Finish: If thickening, whisk cornstarch into milk first. Stir milk into the soup and heat until it returns to a simmer. Stir in sour cream and cheese until smooth. Season to taste and serve.
Serving Suggestions
Serve the soup hot with optional garnishes like chopped chives, extra shredded cheddar, a crack of black pepper, or a dollop of sour cream. For a heartier meal, pair with crusty bread, cornbread, or a crisp side salad.

Storage
- Refrigerate: Store leftovers in an airtight container for up to 4 days.
- Freeze: Cool completely, then transfer to a freezer-safe container for up to 3 months.
- Reheat: Gently warm on the stovetop over low heat or in the microwave until hot, stirring occasionally.
