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

Step 1: Prepare the Crockpot
Begin by spraying the inside of your crockpot with non-stick cooking spray to prevent sticking and make cleanup a breeze. This step is crucial for ensuring your Crockpot Pierogi Casserole with Kielbasa comes out perfectly. Once done, gather your ingredients to make the layering easier.

Step 2: Layer the Ingredients
Place half of the frozen pierogi at the bottom of the crockpot, arranging them evenly for thorough cooking. Next, layer half of the sliced kielbasa and half of the chopped onion over the pierogi. This layering process enhances the flavors, making every bite of your casserole delightful.

Step 3: Mix the Sauce
In a separate bowl, combine the condensed cream of mushroom soup, sour cream, and melted butter. Stir the mixture until it’s smooth and creamy, ensuring no lumps remain. This rich sauce will envelop your ingredients, adding a luscious texture to your Crockpot Pierogi Casserole with Kielbasa.

Step 4: Add the Sauce
Spread half of the creamy sauce mixture over the layered ingredients in the crockpot. You want to cover them evenly to infuse the flavors throughout the casserole. This step is essential to achieving that comforting creaminess that defines this dish.

Step 5: Repeat the Layers
Add another layer by repeating the process with the remaining pierogi, kielbasa, and onion. Follow this with the rest of the creamy sauce, ensuring everything is well-distributed. These layers will meld beautifully as they cook, creating a hearty, satisfying dinner.

Step 6: Slow Cook to Perfection
Cover the crockpot with its lid and set it to cook on low for 4 to 5 hours. As it slowly cooks, the pierogi will become tender, and the flavors will meld. You know it’s done when the pierogi are light and fluffy, giving a comforting appearance.

Step 7: Add the Cheese
In the last 30 minutes of cooking, carefully sprinkle the shredded cheddar cheese over the top of the casserole. This step allows the cheese to melt and bubble, creating a deliciously gooey finish that enhances your Crockpot Pierogi Casserole with Kielbasa.

Step 8: Serve and Enjoy
Once the cooking time is complete, carefully scoop out portions of the casserole using a large spoon. Serve it warm, garnished with chives for a fresh touch. The final dish should be rich and creamy, ready to be enjoying with your loved ones.
