How to Make Crockpot Pierogi Casserole with Kielbasa Recipe
Step 1: Prepare the Slow Cooker and Cream Cheese Mixture
Start by giving your slow cooker a generous spray with nonstick cooking spray to prevent sticking. In a medium bowl, combine the softened cream cheese, sour cream, milk, garlic powder, black pepper, and smoked paprika. Whisk these ingredients together until the mixture is silky smooth. This creamy blend is going to infuse your casserole with richness and depth.
Step 2: Layer the Ingredients
Begin layering half of the frozen pierogies evenly on the bottom of the slow cooker. Next, add half of the sliced kielbasa and sprinkle the diced onion over the top. Spoon half of the cream cheese mixture over these layers, spreading gently to cover. Repeat this exact pattern with the remaining pierogies, kielbasa, onion, and cream cheese mixture to create a perfectly structured casserole.
Step 3: Top and Cook
Once your layers are set, sprinkle the shredded cheddar cheese evenly over the entire surface. Cover the slow cooker with its lid and cook on low for 4 to 5 hours, or opt for a quicker 2 to 3 hours on high. You’ll know it’s ready when everything is heated through, bubbly around the edges, and the cheese topping has beautifully melted and melded with the layers beneath.
Step 4: Final Touch and Serve
Before serving, gently stir the casserole to marry the layers together without breaking the pierogies too much. Sprinkle freshly chopped parsley over the top to add a lovely burst of color and a fresh flavor contrast. This step makes your Crockpot Pierogi Casserole with Kielbasa Recipe look inviting and taste even better.
How to Serve Crockpot Pierogi Casserole with Kielbasa Recipe

Garnishes
A sprinkle of fresh parsley is a classic, but don’t hesitate to add a dollop of sour cream or a few crispy fried onions for an extra touch of texture and creaminess. These simple additions elevate the dish visually and flavor-wise, making your serving look and taste like it came from a cozy restaurant.
Side Dishes
This casserole pairs wonderfully with a crisp green salad, roasted vegetables, or even sautéed greens like kale or spinach for a well-rounded meal. The freshness of these sides contrasts perfectly with the creamy, cheesy layers of the casserole, creating a balanced plate that will satisfy any appetite.
Creative Ways to Present
For a crowd-pleasing presentation, transfer your Crockpot Pierogi Casserole with Kielbasa Recipe to a rustic baking dish and pop it under the broiler for 3 to 5 minutes to crisp up the top layer of cheese. Alternatively, serve portions in mini cast iron skillets or deep dishes for a homey, charming touch that sparks joy in every bite.
Make Ahead and Storage
Storing Leftovers
This casserole tastes even better the next day as the flavors have time to mingle, so be sure to store leftovers in an airtight container in the refrigerator for up to 3 days. Simply cover tightly to keep moisture in and prevent the casserole from drying out.
Freezing
If you want to prep in advance, this dish freezes beautifully. Place cooled, leftover portions in freezer-safe containers or bags, labeling them to enjoy within 2 months. When ready, thaw overnight in the fridge before reheating to maintain the best texture.
Reheating
To reheat, warm individual servings gently in the microwave or pop the entire casserole into a 350°F oven, covered with foil, until heated through. For the best experience, sprinkle a little more cheddar on top and broil briefly to revive the lovely cheesy crust.
