Ingredients You’ll Need
This recipe calls for a handful of simple but key ingredients that come together to create layers of flavor and scrumptious texture. Each component plays a vital role—from the creamy cheese blend to the spicy kielbasa, ensuring every bite sings with delight.
- Frozen pierogies (2 boxes, 16 oz each): Using potato and cheese pierogies gives a soft, tender base filled with comforting flavors.
- Kielbasa (14 oz, sliced): This adds a wonderful smoky, meaty bite that balances the creaminess perfectly.
- Cream cheese (8 oz, cubed): Blended into the sauce, it creates rich creaminess without overpowering the other ingredients.
- Shredded cheddar cheese (1 cup): Melts beautifully on top for that irresistible golden, cheesy crust.
- Sour cream (1 cup): Adds a tangy freshness that brightens the overall flavor.
- Chicken broth (1/2 cup): Thins the sauce just enough to keep it luscious and pourable.
- Garlic powder (1/2 tsp): Delivers subtle warmth and depth without overwhelming the dish.
- Onion powder (1/2 tsp): Enhances the savory notes and rounds out the seasoning.
- Black pepper (1/4 tsp): Just a hint of spice to keep things interesting.
- Chopped green onions or chives (1/4 cup, optional): Fresh garnish that adds color and a mild oniony bite.
How to Make Crockpot Pierogi Casserole with Kielbasa Recipe
Step 1: Prepare the Crockpot and Ingredients
First things first, make sure to spray the inside of your crockpot with nonstick spray. This little step helps prevent sticking, making cleanup easy and keeping your pierogies intact. Then, take those frozen pierogies straight from the freezer—no need to defrost—and layer them right into the crockpot along with the sliced kielbasa. The frozen pierogies will slowly cook to tender perfection while soaking up the smoky goodness of the kielbasa.
Step 2: Create the Creamy Sauce
In a separate bowl, mix together the cream cheese cubes, sour cream, chicken broth, garlic powder, onion powder, and black pepper. Whisk this blend until it’s gorgeously smooth and creamy. This combo is where all the magic happens, turning into a velvety sauce that brings together the hearty pierogies and kielbasa in every bite.
Step 3: Pour and Layer the Casserole
Next, pour this luscious sauce evenly over the pierogies and kielbasa in the crockpot. Spread it out so every piece will soak up the flavor. After that, sprinkle the shredded cheddar cheese liberally over the top. This cheese layer will melt down into a bubbly, golden delight that makes the entire dish irresistible.
Step 4: Slow Cook to Perfection
Cover your crockpot and cook on low for 3 to 4 hours, or if you’re short on time, use the high setting for 2 to 2.5 hours. You’ll know it’s ready when the pierogies are tender, and the sauce has thickened to a creamy consistency. Before serving, gently stir the casserole to combine all those flavors fully. Resist the urge to over-stir—that will keep your pierogies just right and not mushy.
How to Serve Crockpot Pierogi Casserole with Kielbasa Recipe

Garnishes
Adding a sprinkle of fresh chopped green onions or chives over the top immediately lifts this dish visually and taste-wise. The freshness gives a nice bite contrast to the creamy casserole, making every spoonful pop with little bursts of flavor and color that delight both your eyes and palate.
Side Dishes
This casserole is a dish all on its own but pairs wonderfully with simple sides for balance. A crisp green salad with a light vinaigrette or steamed vegetables like broccoli or green beans provide a fresh crunch and brighten the meal. These sides complement the rich casserole without competing.
Creative Ways to Present
For a fun twist during casual get-togethers, serve the casserole in mini crockpot liners or individual ramekins. You could also top each serving with a dollop of sour cream or a sprinkle of crispy fried onions for added texture. This dish is perfect for a cozy night in but can easily double as a crowd-pleaser at potlucks or family dinners.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store them in an airtight container in the refrigerator. The flavors meld even more after resting overnight. Leftover casserole will keep well for 3 to 4 days, making for easy next-day meals with all the comfort intact.
Freezing
This casserole freezes beautifully, which is great for meal prep or if you want to save some for a later date. Simply let it cool completely, then transfer portions to freezer-safe containers or bags. It will keep well for up to 2 months. Just remember to thaw overnight in the fridge before reheating.
Reheating
To warm up leftovers, the best way is to reheat gently in a microwave or in the oven at 350°F until heated through. Stir halfway through reheating for even warmth and to bring back that creamy texture. Just be careful not to overcook, as the pierogies can become overly soft.
FAQs
Can I use fresh pierogies instead of frozen?
Absolutely! Fresh pierogies will work well and may reduce the cooking time slightly. Just keep an eye on the casserole to avoid overcooking the pierogies since fresh ones are more delicate.
Is it necessary to sauté the kielbasa before adding it?
Not at all. The recipe works great with kielbasa added straight in. However, sautéing it beforehand adds an extra layer of caramelized flavor and slightly crisp texture, which some people love.
Can I substitute the chicken broth with vegetable broth?
Yes! If you prefer a non-meat option or simply want a different flavor profile, vegetable broth is a perfect substitute and keeps the dish just as moist and tasty.
Is this casserole suitable for a large crowd?
This recipe yields around six servings but scales up nicely by doubling or tripling the quantities. Using a larger slow cooker will make feeding a crowd a breeze.
Can I add vegetables to this Crockpot Pierogi Casserole with Kielbasa Recipe?
Definitely! You can add diced onions, bell peppers, or mushrooms for extra nutrition and texture. Just be mindful of moisture levels so the casserole doesn’t get too watery.
