Step‑by‑Step Instructions for Crockpot Pierogi Casserole with Kielbasa
Step 1: Combine Ingredients
In a 4-6 quart crockpot, add three cups of chicken broth, then layer in the frozen cheddar pierogies and sliced kielbasa. Sprinkle one cup of shredded cheddar cheese over the top. These ingredients will form the heart of your Crockpot Pierogi Casserole with Kielbasa, creating a cozy, creamy foundation for the dish.
Step 2: Cook the Casserole
Set the crockpot to high and cover it, letting it cook for 3-4 hours or on low for 6 hours. Keep an eye on it to ensure the pierogies stay tender and don’t become mushy. The flavors will meld beautifully, and you’ll start to smell the savory aroma of kielbasa mingling with cheesy goodness.
Step 3: Prepare Cream Cheese Mixture
About 30 minutes before the cooking time is complete, take 4 ounces of cream cheese and the remaining broth to a small saucepan. Heat gently over low heat, stirring continuously until the mixture is smooth and creamy. This step enhances the richness of your casserole, making it even more delightful.
Step 4: Final Assembly
Once the cooking time is up, pour the warm cream cheese mixture into the crockpot, gently stirring to combine all the elements. Then, layer the remaining shredded cheddar cheese on top. Cover again and cook on low for an additional 30 minutes to allow the cheese to melt and tie everything together beautifully.
Step 5: Serve
When the casserole is done, it should look creamy and gooey with the cheeses melted perfectly over the top. For a touch of brightness, garnish with sliced green onions before serving. Enjoy this comforting Crockpot Pierogi Casserole with Kielbasa hot, perfect for cozy family dinners.

Expert Tips for Crockpot Pierogi Casserole
-
Browning Kielbasa: Sauté the kielbasa in a pan before adding it to the slow cooker to enhance flavor and texture with a delicious caramelization.

Avoid Mushy Pierogies: Stick to the recommended cooking times; overcooking can cause the pierogies to break apart and lose their texture.
-
Smooth Cream Cheese: Gradually warm it with broth to prevent separation. If it boils, it may become grainy; low heat is key!
-
Gentle Mixing: Be gentle when stirring in the cream cheese mixture to maintain the pierogies’ shape and texture; too much force can cause them to break.
-
Flavor Variations: Experiment with different types of kielbasa or smoked sausage, and add veggies like bell peppers or spinach to suit your taste in this hearty crockpot pierogi casserole.
