Step‑by‑Step Instructions for Crockpot Pierogi Casserole with Kielbasa
Step 1: Prepare the Crockpot
Begin by spraying your crockpot generously with non-stick cooking spray. This step is essential to ensure that nothing sticks and makes serving easier later. Place your crockpot on a stable surface, ready to layer in the delicious ingredients for the Crockpot Pierogi Casserole with Kielbasa.
Step 2: Layer the Pierogi
Carefully layer half of the frozen pierogi at the bottom of the crockpot. This forms the base of your casserole, ensuring a hearty foundation. As you layer, arrange them in a single, even layer for balanced cooking and maximum flavor in every bite.
Step 3: Add Kielbasa and Onion
Next, sprinkle half of the sliced kielbasa evenly over the layer of pierogi. Follow this by adding half of the chopped onion on top. The onion will add a delightful sweetness that complements the savory kielbasa, infusing the dish with a wonderful aroma as it cooks.
Step 4: Mix the Creamy Base
In a separate bowl, combine the condensed cream of mushroom soup, sour cream, and melted butter. Whisk these ingredients together until smooth and creamy. This mixture will bring all the flavors together in the Crockpot Pierogi Casserole with Kielbasa, creating a luscious sauce that envelops the layers.
Step 5: Spread the Soup Mixture
Carefully spread half of the creamy soup mixture over the pierogi, kielbasa, and onion layers in the crockpot. Ensure even coverage, allowing the sauce to seep into the layers for maximum richness. This step will set the stage for an incredibly flavorful casserole.
Step 6: Repeat the Layers
Now, repeat the layering process with the remaining frozen pierogi, followed by the rest of the kielbasa and onion. Finish by pouring the second half of the soup mixture atop these layers. This creates a double-decker effect, enhancing the heartiness of your Crockpot Pierogi Casserole with Kielbasa.
Step 7: Cook the Casserole
Cover the crockpot with its lid and set it to cook on low for 4 to 5 hours. During this time, the flavors will meld beautifully, and the pierogi will become wonderfully tender. Keep an eye out for bubbles around the edges as a sign of doneness.
Step 8: Add Cheddar Cheese
In the last 30 minutes of cooking, carefully remove the lid and sprinkle shredded cheddar cheese evenly over the top of the casserole. Replace the lid and continue cooking until the cheese melts into a gooey layer of deliciousness, adding an irresistible touch to your dish.
Step 9: Garnish and Serve
Once the cooking time is complete, serve the Crockpot Pierogi Casserole with Kielbasa warm. Don’t forget to garnish with freshly chopped chives, offering a pop of color and flavor. This comforting meal is perfect for sharing and enjoying with loved ones at the dinner table.

Expert Tips for Crockpot Pierogi Casserole
Brown the Kielbasa: Sauté kielbasa in a pan before adding it to the crockpot for a deeper, more savory flavor.
Use High-Quality Pierogi: Opt for high-quality frozen pierogi; they hold up better during cooking and contribute to a satisfying texture.

Mind the Cooking Time: Keep an eye on cooking times; overcooking can make the pierogi too soft. Check for tenderness at the 4-hour mark.
Garnish Smartly: For added freshness, sprinkle some chopped parsley or green onions alongside the chives as a vibrant finishing touch.

Crockpot Pierogi Casserole with Kielbasa Recipe FAQs
What type of pierogi should I use for this recipe?

How can I ensure the casserole doesn’t turn out too soft?
To prevent the pierogi from becoming overly soft, I suggest checking the casserole around the 4-hour mark. If the pierogi are tender but still have some firmness, it’s the perfect time to add the cheddar cheese. Stay mindful of your slow cooker settings and cooking times!
