Combine all ingredients in your crockpot.
Cook on high 3-4 hours, or on low 6 hours.
Preheat oven to 350° F
Grease a 13×9 baking dish.
In a saucepan, combine chicken broth and cream cheese. Heat until cream cheese is melted – stir occasionally to incorporate the melting cream cheese.
Begin with a layer of frozen pierogis in the bottom of the baking dish, then a layer of kielbasa, a layer of the cream cheese sauce, a layer of shredded cheddar cheese.
Repeat the layering.
Bake for 30-45 minutes until the cheese is bubbly and beginning to look a golden brown.
