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

Step 1: Prep the Crockpot
Begin by spraying the inside of your crockpot with non-stick cooking spray to ensure easy cleanup later. This quick step sets the stage for your Crockpot Pierogi Casserole with Kielbasa, creating a non-stick surface that helps the ingredients meld together beautifully.

Step 2: Layering Ingredients
Next, place half of the frozen pierogi at the bottom of the crockpot, followed by half of your kielbasa slices and a layer of diced onion. This rich base ensures that every delicious layer interacts as it cooks. Spread the ingredients evenly and let the colors shine as they create a beautiful foundation for the casserole.

Step 3: Mix and Spread Sauce
In a mixing bowl, combine the cream of mushroom soup, sour cream, and melted butter until smooth. This creamy sauce will tie together your Crockpot Pierogi Casserole with Kielbasa, providing richness and flavor. Carefully spread half of this mixture over the layered ingredients, ensuring all is covered for even cooking.

Step 4: Repeat Layers
Follow up with the second layer by placing the remaining frozen pierogi, kielbasa, and onion on top of the sauce. This repeat layering ensures every bite is comforting and satisfying. Pour the remaining sauce mixture over this layer, giving it a final blanket of creamy goodness and enticing aroma.

Step 5: Cook
Cover the crockpot with its lid and cook on low for 4 to 5 hours. This slow-cooking process allows the pierogi to become tender and the flavors to develop fully. Check for doneness; the pierogi should be soft and the kielbasa heated through, signaling it’s nearly time to enjoy!

Step 6: Add Cheese
In the last 30 minutes of cooking, sprinkle the shredded cheddar cheese over the top for a melty finish. Cover the crockpot again and let the cheese melt into a gooey layer that beautifully complements the dish. The enticing aroma will fill your kitchen, hinting at the deliciousness to come.

Step 7: Serve
Once cooked, carefully serve your Crockpot Pierogi Casserole with Kielbasa while warm. For a colorful finish, garnish with freshly chopped chives, which add a pop of flavor and brightness. This comforting dish pairs wonderfully with a simple green salad or your favorite bread for a complete meal.
