Ingredients for Crock pot Pierogi Casserole with Kielbasa Recipe

2 (16-ounce) packages frozen potato and cheese pierogies
1 pound kielbasa sausage, sliced into ¼-inch pieces
1 (10.5-ounce) can condensed cream of mushroom soup
1 cup sour cream
1 cup shredded sharp cheddar cheese
1 small yellow onion, diced
2 tablespoons unsalted butter, melted
½ teaspoon garlic powder
¼ teaspoon black pepper
2 tablespoons fresh chives or parsley, chopped (optional for garnish)

Directions for Crock pot Pierogi Casserole with Kielbasa Recipe

Step 1: Prep the Crockpot

Lightly grease your 6-quart slow cooker insert with melted butter or nonstick spray to make cleanup a breeze.

Step 2: Layer the Ingredients

Arrange half the frozen pierogies in an even layer in the bottom of the crockpot. Top with half of the sliced kielbasa, half the diced onion, and half the shredded cheddar cheese.

Step 3: Mix the Creamy Sauce

In a medium bowl, whisk together the cream of mushroom soup, sour cream, melted butter, garlic powder, and black pepper until smooth. Learn more about using cream soups in casseroles here.

Step 4: Assemble the Layers

Pour half of the creamy mixture evenly over the bottom layer in the crockpot. Repeat with remaining pierogies, kielbasa, onion, cheddar cheese, and sauce mixture.

Step 5: Slow Cook to Perfection

Cover and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours, until bubbly and heated through. The sauce should be thick and creamy; pierogies tender.

Step 6: Add Finishing Touches

Sprinkle with fresh chives or parsley just before serving for a pop of color and fresh flavor.
