I first made this recipe on a particularly hectic Wednesday when I needed something foolproof for dinner but had back-to-back meetings all afternoon.

This crockpot pierogi casserole with kielbasa layers simple ingredients that transform during the slow cooking process into something truly special. The slow cooker pierogi bake requires almost no prep work and delivers maximum flavor with minimal effort.

Simple Ingredients for Crockpot Pierogi Casserole

I always use Mrs. T’s Cheddar Pierogies for this recipe because they hold up beautifully during the long cooking time without turning mushy. Pro tip: you don’t need to thaw the frozen pierogies before adding them to the crockpot.

• 3 packages Mrs. T’s Cheddar Pierogies (frozen)
• 4 cups chicken broth
• 1 block (8 ounces) cream cheese
• 1 cup shredded cheddar cheese
• 1 pound kielbasa, sliced
• Salt and pepper to taste
• Sliced green onions for garnish (optional)

Pro tip: I recommend browning the kielbasa slices in a skillet before adding them to the crockpot. This extra step enhances the smoky flavor and adds visual appeal to the finished dish.

How to Make Crockpot Pierogi Casserole with Kielbasa

I recommend using a 4-6 quart crockpot for this recipe to ensure everything cooks evenly and has enough room to bubble without overflowing.

Step 1: In a 4-6 quart crockpot, combine 3 cups of chicken broth with the frozen pierogies, sliced kielbasa, and shredded cheddar cheese. Stir gently to distribute ingredients evenly throughout the pot.

Step 2: Set crockpot to cook on high for 3-4 hours or on low for 6 hours. The pierogies should become tender and the flavors will meld together beautifully during this time.

Step 3: Approximately 30 minutes before the cooking time ends, warm the cream cheese block with the remaining 1 cup of chicken broth. You can do this in the microwave in 30-second intervals or on the stovetop over low heat, whisking constantly.

Step 4: Whisk the cream cheese and broth mixture until completely smooth with no lumps remaining. The consistency should be silky and pourable.

Step 5: Pour the smooth cream cheese mixture into the crockpot, stirring well to integrate it throughout the casserole. Every pierogi should be coated in the creamy sauce.

Step 6: Sprinkle the remaining cup of shredded cheddar cheese evenly over the top of the casserole, creating a complete layer.

Step 7: Cover the crockpot and set to cook on low for an additional 30 minutes. This allows the cheese to melt completely and the flavors to bind together into a cohesive dish.

Step 8: Serve hot, garnished with sliced green onions if desired. The casserole should be creamy, cheesy, and incredibly comforting.

Reheat individual portions in the microwave or warm the entire casserole on the stovetop over medium heat, adding a splash of chicken broth if needed to maintain the creamy consistency.

Pro tip: This casserole freezes beautifully for up to 3 months in a freezer-safe container. Thaw overnight in the refrigerator and reheat gently on the stovetop, stirring occasionally to prevent sticking.
