Step 1

Combining Ingredients in Crockpot: In a 4-6 quart crockpot, combine three cups of the chicken broth, the frozen pierogies, sliced kielbasa, and shredded cheddar cheese. Ensure that the ingredients are evenly distributed.

Step 2

Cooking the Casserole: Set the crockpot to cook on high for 3-4 hours, or alternatively, on low for 6 hours. This long cooking time allows the flavors to fully develop and meld together, resulting in a cohesive and flavorful dish.

Step 3

Preparing Cream Cheese Mixture: Approximately 30 minutes before the end of the cooking time, warm the block of cream cheese with the remaining one cup of chicken broth. This can be done either in a microwave or on a stovetop. Once warmed, whisk the mixture until it achieves a smooth consistency.

Step 4

Final Assembly: Pour the smooth cream cheese mixture into the crockpot, stirring well to integrate. Sprinkle the remaining cup of shredded cheddar cheese over the top. Cover the crockpot and set it to cook on low for an additional 30 minutes, allowing the cheese to melt and the flavors to bind.

Step 5

Serving: Serve the casserole hot, ideally garnished with sliced green onions if desired, to add both color and a mild, oniony crunch that complements the rich flavors of the dish.
