Description

Hearty slow cooker sausage and potato casserole delivers comfort straight from Polish kitchens. Savory sausage, tender potatoes, and rich seasonings create a satisfying meal that warms you from the inside out.


Ingredients

Scale

Main Proteins:

  • 14 ounces (397 grams) kielbasa sausage, cut into small pieces

Starches and Vegetables:

  • 1 (32 ounces / 907 grams) bag of hash browns (or substitute fresh diced potatoes)
  • 1 small onion, diced

Dairy and Seasonings:

  • 2 ½ cups shredded cheddar cheese
  • 1 (10.5 ounces / 298 grams) can cream of mushroom soup
  • ½ cup sour cream
  • 1 teaspoon creole seasoning (or your favorite seasoning blend)
  • Salt and pepper to taste

Instructions

  1. Prepare the slow cooker by applying a light coating of cooking spray to prevent sticking and ensure easy cleanup.
  2. Layer the crispy hash browns as the foundational base, creating a hearty potato canvas for the casserole.
  3. Slice the kielbasa into bite-sized medallions, distributing them evenly across the hash brown layer to ensure consistent flavor in every serving.
  4. Dice the onions finely, sprinkling them throughout the mixture to add a subtle aromatic depth and sweetness.
  5. Generously scatter two-thirds of the sharp cheddar cheese over the potato and sausage mixture, allowing the cheese to melt and create a creamy texture.
  6. Whisk together the cream of mushroom soup, tangy sour cream, robust creole seasoning, delicate salt, and freshly ground pepper in a separate mixing bowl until smooth and well-integrated.
  7. Gently pour the seasoned soup mixture over the layered ingredients, carefully folding and stirring to ensure every morsel is coated and seasoned.
  8. Sprinkle the remaining cheddar cheese across the top, creating a golden, melty crown for the casserole.
  9. Secure the slow cooker lid and allow the dish to simmer on low temperature for approximately 6 hours, or on high for 4 hours, until the potatoes become tender and the flavors marry completely.
  10. Once cooking is complete, let the casserole rest for a few minutes before serving to allow the ingredients to set and flavors to settle.
  11. Serve piping hot, offering a comforting and satisfying meal that blends hearty potatoes, savory sausage, and melted cheese.
