Origin:

This casserole is a fusion of Eastern European and American Midwest comfort food traditions. Kielbasa, a Polish-style smoked sausage, pairs perfectly with classic American casserole elements like potatoes, cheese, and cream-based sauces—creating a filling and flavorful one-dish meal popular in home kitchens across the U.S.

Ingredients:

Main Ingredients:

  • 1 lb (450 g) kielbasa sausage, sliced into 1/4-inch rounds
  • 6 cups diced or shredded potatoes (or 1 bag frozen hash browns)
  • 1 small onion, finely diced
  • 2 cups shredded cheddar cheese
  • 1 can (10.5 oz) cream of mushroom or cream of chicken soup
  • 1 cup sour cream
  • 1/2 cup milk
  • 1 tsp garlic powder
  • 1 tsp paprika (optional)
  • Salt and pepper to taste
  • 2 tbsp butter (for greasing and sautéing)

Optional Ingredients/Substitutions:

  • Swap sour cream for plain Greek yogurt for a lighter version.
  • Use cream of celery or a homemade roux instead of canned soup.
  • Add frozen peas, corn, or broccoli for extra veggies.
  • Use Monterey Jack or a cheese blend for different flavors.
  • Top with crushed Ritz crackers, cornflakes, or panko for a crunchy topping.

Instructions:

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
  2. In a large skillet over medium heat, sauté kielbasa slices until browned, about 5–7 minutes. Remove from heat.
  3. In a large bowl, mix together the soup, sour cream, milk, garlic powder, paprika, salt, and pepper.
  4. Stir in the diced potatoes (or frozen hash browns), half of the cheese, onion, and cooked kielbasa.
  5. Pour the mixture into the prepared casserole dish and spread evenly.
  6. Top with the remaining shredded cheese.
  7. Bake uncovered for 40–45 minutes, or until bubbly and golden brown on top.
  8. Let rest for 5–10 minutes before serving.

Tips for Success:

  • If using fresh potatoes, dice them evenly and parboil for 5–7 minutes to soften before baking.
  • Don’t skip browning the kielbasa—it adds deep, smoky flavor.
  • Use sharp cheddar for the most flavor impact.
  • For a crispier top, broil the last 2–3 minutes of baking.
  • Let the casserole rest after baking—it thickens and cuts more cleanly.

Recommendations:

  • Pair with a side salad, green beans, or roasted Brussels sprouts to balance the richness.
  • Make it ahead of time and refrigerate overnight before baking.
  • It also freezes well—just thaw and reheat in the oven or microwave.
  • Serve it as a main dish or a hearty side at brunches, dinners, or gatherings.
