Ingredients

Scale
  • 12–14 oz smoked kielbasa, sliced into ¼-inch rounds
  • 1 medium yellow onion, diced
  • 3–4 cloves garlic, minced
  • 2 lbs russet potatoes, peeled and diced into ½-inch cubes
  • 4 cups low-sodium chicken broth
  • 1 ½ cups whole milk
  • 2 tablespoons all-purpose flour
  • 2 tablespoons unsalted butter
  • ½ teaspoon dried thyme
  • ¼ teaspoon smoked paprika (optional)
  • Salt and black pepper to taste
  • Fresh parsley for garnish

Instructions

  1. Prep your ingredients: dice the onion, mince the garlic, peel and dice the potatoes into ½-inch cubes, and slice the kielbasa into ¼-inch thick rounds.
  2. Place a large pot over medium-high heat. Add the sliced kielbasa in a single layer and cook for 2-3 minutes per side until nicely browned. Use a slotted spoon to transfer the kielbasa to a plate and set aside. Leave about 1 tablespoon of rendered fat in the pot.
  3. Reduce heat to medium. Add the butter to the pot with the reserved fat. Once melted, add the diced onion and cook for about 3 minutes until soft and translucent. Add the minced garlic and cook for another 30 seconds until fragrant.
  4. Sprinkle the flour over the cooked onions and garlic. Stir constantly for about 1 minute to cook out the raw flour taste.
  5. Slowly pour in the chicken broth while stirring constantly to prevent lumps. Add the milk, dried thyme, and smoked paprika (if using). Stir until smooth. Add the diced potatoes and the browned kielbasa back to the pot. Stir to combine.
  6. Increase heat to high and bring the soup to a gentle boil. Once boiling, reduce heat to low, cover the pot, and let simmer for 15-20 minutes until the potatoes are fork-tender.
  7. Remove the pot from heat. Taste and season with salt and black pepper. For an even creamier texture, gently mash a few of the potatoes in the pot with a potato masher.
  8. Ladle the hot soup into bowls and garnish with fresh chopped parsley. Serve immediately with crusty bread or a simple side salad.

Notes

For a thicker soup, mash some of the potatoes directly in the pot. To prevent curdling, add the milk with the broth, not after the potatoes have started cooking. The soup tastes even better the next day as flavors meld.
