History and Background of Pierogi and Kielbasa

Pierogies have deep roots in Eastern European cuisine, particularly in Polish, Ukrainian, and Slovak traditions. Traditionally, pierogies are dumplings filled with potatoes, cheese, meat, or vegetables and served boiled, sautéed, or baked. Over time, they became a staple comfort food because they were affordable, filling, and versatile.

Similarly, kielbasa is a well-known Polish sausage made from seasoned pork or beef and smoked for rich flavor. When combined, pierogies and kielbasa create a classic pairing that balances creamy textures with savory, smoky notes. In modern kitchens, this combination has evolved into convenient casseroles and slow cooker meals. Therefore, the Crockpot Pierogi Casserole with Kielbasa is a contemporary twist on traditional comfort food, blending cultural heritage with modern convenience.

Ingredients

Frozen pierogies (16 oz packages, cheddar or potato and cheese recommended)
Kielbasa sausage, sliced
Cream of mushroom soup
Shredded cheddar cheese
Chicken broth
Sour cream (optional)
Small onion, diced or sliced (optional)
Salt
Black pepper
Fresh parsley for garnish (optional)

Preparation Method

Step 1: Prepare the Slow Cooker Base

First, lightly grease the inside of your crockpot to prevent sticking. Then, arrange a layer of frozen pierogies at the bottom of the slow cooker. After that, scatter sliced kielbasa evenly over the pierogies. If you choose to use onion, add it at this stage to ensure it softens and releases flavor as it cooks. This base layer forms the foundation of the casserole and ensures even cooking throughout.

Step 2: Mix the Creamy Sauce

Next, in a medium bowl, combine the cream of mushroom soup and chicken broth. Stir until the mixture becomes smooth and well blended. If you prefer a richer texture, add sour cream to the mixture. Then, mix in a portion of the shredded cheddar cheese and season with salt and black pepper. At this point, the sauce should be creamy and slightly thick, which helps coat the pierogies and sausage evenly during cooking.

Step 3: Assemble the Casserole

After preparing the sauce, pour it evenly over the layered pierogies and kielbasa in the crockpot. Make sure all ingredients are well coated, as this step is crucial for even cooking and flavor distribution. If necessary, gently press the pierogies down so they sit beneath the sauce. This ensures they absorb moisture and soften properly while cooking.

Step 4: Slow Cook to Perfection

Now, cover the crockpot with its lid and set it to cook. You can choose the low setting for 4 to 6 hours or the high setting for 2 to 3 hours. Cooking on low is recommended for the best texture and flavor development. During this time, the pierogies will become tender, the kielbasa will release its smoky flavor, and the sauce will thicken into a rich, creamy consistency.

Step 5: Add Cheese and Finish

Shortly before serving, sprinkle the remaining shredded cheddar cheese over the top of the casserole. Cover again and allow the cheese to melt completely. This final step creates a gooey, golden topping that enhances both flavor and presentation. Once the cheese has melted, garnish with fresh parsley if desired. Then, serve hot and enjoy the comforting flavors of this slow cooker meal.

Frequently Asked Questions

Can I use fresh pierogies instead of frozen?

Yes, you can use fresh pierogies. However, frozen pierogies are recommended because they hold their shape better during slow cooking. If using fresh pierogies, reduce the cooking time slightly to avoid over-softening.

What type of kielbasa works best for this recipe?

Smoked kielbasa works best because it adds deep flavor to the casserole. However, you can also use turkey kielbasa or beef kielbasa for a lighter alternative. The key is choosing a well-seasoned sausage to enhance the overall taste.

Can I make this recipe ahead of time?

Absolutely. You can assemble the ingredients in the crockpot insert, cover it, and refrigerate overnight. When ready to cook, simply place the insert into the slow cooker and start the cooking process. This makes it an excellent option for meal prep or busy schedules.

How can I make this casserole creamier?

To achieve a creamier texture, increase the amount of sour cream or add a splash of heavy cream to the sauce mixture. Additionally, using extra shredded cheese will enhance the richness and thickness of the casserole.

Can I add vegetables to this recipe?

Yes, adding vegetables is a great way to customize this dish. Bell peppers, mushrooms, spinach, or broccoli work well and add both flavor and nutrition. Simply layer them with the pierogies and kielbasa before adding the sauce.

How should leftovers be stored?

Store leftovers in an airtight container in the refrigerator for up to three days. When reheating, use the microwave or stovetop with a small splash of broth or milk to restore moisture and creaminess.
