Ingredients

Scale
  • 1 tablespoon olive oil
  • 1 pound smoked kielbasa sausage, sliced
  • 1 medium yellow onion, chopped
  • 2 cloves garlic, minced
  • 4 cups chicken broth
  • 1 pound russet potatoes, peeled and diced into 1/2-inch pieces
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 cups whole milk or half-and-half
  • 1 cup shredded white cheddar cheese
  • 2 tablespoons all-purpose flour (optional, for thickening)

Instructions

  1. Heat the olive oil in a large pot or Dutch oven over medium heat. Add the sliced kielbasa and cook until lightly browned, about 5 minutes. Remove the sausage with a slotted spoon and set aside, leaving any rendered fat in the pot.
  2. Add the chopped onion to the pot and cook until softened, about 5 minutes. Add the minced garlic and cook for 1 minute until fragrant.
  3. Stir in the flour, if using, and cook for 1 minute. Slowly whisk in the chicken broth, scraping up any browned bits from the bottom of the pot.
  4. 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 when pierced with a fork.
  5. Stir in the reserved kielbasa and the milk or half-and-half. Heat through gently, but do not let the soup boil once the dairy is added.
  6. Remove the pot from the heat. Gradually stir in the shredded white cheddar cheese until it is completely melted and the soup is creamy.
  7. Taste and adjust seasoning if needed. Serve hot with crusty bread.

Notes

  • For a thicker soup, mash about 1 cup of the potatoes against the side of the pot before adding the milk.
  • You can substitute smoked sausage for kielbasa if needed.
  • Use low-sodium chicken broth to better control the final salt content.
