What You Need To Make This Recipe

Pierogi: These soft, dumpling-like pockets of dough are typically filled with mashed potatoes, cheese, or other savory ingredients. For this recipe, frozen pierogi work perfectly, as they hold up well during the slow cooking process and absorb the flavors of the other ingredients.

Kielbasa: This Polish sausage adds a smoky, savory depth to the dish. Kielbasa is already fully cooked, so it just needs to be sliced and added to the crockpot. Its robust flavor pairs wonderfully with the creamy pierogi and cheese.

Cheddar Cheese: Sharp cheddar cheese brings a tangy, creamy element to the casserole. When melted, it creates a gooey, irresistible layer that ties everything together.

Cream of Mushroom Soup: This pantry staple adds richness and a velvety texture to the dish. It also helps keep the pierogi moist as they cook.

Milk: Milk thins out the cream of mushroom soup, creating a smooth, pourable sauce that coats the pierogi and kielbasa evenly.

Onion: Sautéed onions add a touch of sweetness and depth to the dish. They complement the smoky kielbasa and creamy pierogi beautifully.

Butter: A little butter adds richness and helps brown the onions, enhancing their flavor. It also adds a touch of indulgence to the finished dish.

Garlic Powder: This seasoning adds a subtle, savory note that enhances the overall flavor profile without overpowering the other ingredients.

Paprika: A sprinkle of paprika adds a hint of warmth and color to the dish, making it even more visually appealing.

Ingredients List

1 package (16 oz) frozen pierogi
1 lb kielbasa, sliced into rounds
2 cups shredded sharp cheddar cheese
1 can (10.5 oz) cream of mushroom soup
1 cup milk
1 medium onion, thinly sliced
2 tablespoons butter
1 teaspoon garlic powder
1/2 teaspoon paprika
Salt and pepper to taste

How to Make Crockpot Pierogi Casserole with Kielbasa

Step 1: Prepare the Onions

In a skillet, melt the butter over medium heat. Add the sliced onions and sauté until they are soft and golden brown, about 5-7 minutes. This step brings out the natural sweetness of the onions and adds a layer of flavor to the casserole.

Step 2: Layer the Ingredients in the Crockpot

Start by spreading a layer of frozen pierogi at the bottom of the crockpot. Next, add a layer of sautéed onions, followed by slices of kielbasa. Sprinkle a portion of the shredded cheddar cheese over the top. Repeat these layers until all the ingredients are used, finishing with a final layer of cheese.

Step 3: Mix the Sauce

In a medium bowl, whisk together the cream of mushroom soup, milk, garlic powder, paprika, and a pinch of salt and pepper. Pour this mixture evenly over the layered ingredients in the crockpot. The sauce will seep through the layers, ensuring everything is well-coated and flavorful.

Step 4: Cook on Low

Cover the crockpot and cook on low for 4-5 hours. The slow cooking process allows the pierogi to become tender and the flavors to meld together. Avoid opening the lid too often to maintain the heat and moisture.

Step 5: Serve and Enjoy

Once the cooking time is up, give the casserole a gentle stir to combine the layers. Serve hot, garnished with fresh parsley or a sprinkle of paprika if desired. This dish is perfect on its own or paired with a simple side salad.

Tips for Making this Recipe

Use High-Quality Kielbasa: The flavor of the kielbasa is a key component of this dish, so opt for a high-quality brand or visit a local butcher for the best results.
Customize the Cheese: If you prefer a different type of cheese, such as mozzarella or Monterey Jack, feel free to swap it in.
Add Vegetables: For extra nutrition, consider adding sautéed mushrooms, bell peppers, or spinach to the layers.
Don’t Overcook: Keep an eye on the casserole toward the end of the cooking time to prevent the pierogi from becoming too soft or mushy.
Make It Ahead: Assemble the casserole the night before and store it in the fridge. In the morning, simply place it in the crockpot and cook as directed.
