Step‑by‑Step Instructions for Crockpot Pierogi Casserole with Kielbasa

Step 1: Prepare the Crockpot
Start by spraying the inside of your crockpot generously with non-stick cooking spray to prevent sticking. This will ensure easy cleanup later! If you have a larger crockpot, you may consider adjusting the layers. Lay out all your ingredients in preparation for a seamless assembly and make sure your setting is ready for slow cooking later.

Step 2: Layer the First Pierogi
Begin layering the frozen pierogi by placing half of them at the bottom of the crockpot. Arrange them evenly so they cover the surface. The pierogi should sit snugly, providing a hearty foundation for your Crockpot Pierogi Casserole with Kielbasa. This base layer will soak up flavors as it cooks, giving you a deliciously tender texture.

Step 3: Add Kielbasa and Onion
Next, sprinkle half of the sliced kielbasa and chopped onion over the first layer of pierogi. Aim for an even distribution to ensure every bite is packed with savory goodness. The aromas will start to waft through your kitchen, tempting you even more as the dish begins to take shape.

Step 4: Mix the Creamy Sauce
In a mixing bowl, combine the condensed cream of mushroom soup, sour cream, and melted butter. Stir thoroughly until the mixture is smooth and creamy, creating a luscious sauce that’ll bring everything together. This step adds richness to your casserole and balances the flavors beautifully, ensuring each bite is heavenly.

Step 5: First Sauce Layer
Spread half of the creamy sauce mixture over the first layered ingredients in the crockpot. Use a spatula or the back of a spoon to ensure it coats evenly over the pierogi and sausage. This will help infuse flavor and moisture, making the pierogi and kielbasa oh-so-tender and flavorful as they cook.

Step 6: Repeat the Layers
Now, repeat the layering process by placing the remaining frozen pierogi over the sauce, followed by the rest of the kielbasa and onion. Finish with another spread of the remaining creamy sauce on top. This second layer will add depth and flavor, marrying all the ingredients as they cook together.

Step 7: Set to Cook
Cover the crockpot with its lid and set it to cook on low for 4 to 5 hours. As the hours pass, you will enjoy the relaxing aromas filling your space, signaling the comfort soon to come. Check for doneness around the 4-hour mark—your pierogi should be tender and melded with the flavors of kielbasa.

Step 8: Add the Cheddar
About 30 minutes before serving, remove the lid and sprinkle the shredded cheddar cheese over the top. Replace the lid to allow the cheese to melt beautifully while the casserole continues to heat. The melted cheese will create a delightful, gooey layer that adds flavor and a comforting finish to your dish.

Step 9: Serve and Garnish
Your Crockpot Pierogi Casserole with Kielbasa is ready when the cheese is bubbly and melted. Serve warm and garnish with freshly chopped chives on top for a pop of color and freshness. Pair this casserole with a simple green salad or steamed veggies for a well-rounded meal that your family will adore.

Make Ahead Options

To maintain quality, ensure the casserole is tightly covered to prevent drying out. When you’re ready to serve, simply cook it on low for 4 to 5 hours, adding the cheddar during the last 30 minutes to melt beautifully. This way, you can enjoy a comforting meal with minimal effort!
