Ingredients You’ll Need

The beauty of this Crock Pot Pierogi and Kielbasa Casserole lies in its simple but mighty ingredient list. Each element is essential—whether adding a pop of color, a note of smoky flavor, or that coveted cheesy stretch. Here’s how they all play their part in making this casserole unforgettable.

Chicken Broth: Deepens the flavors and keeps everything irresistibly moist and saucy.
Frozen Pierogies (cheddar or onion): The star of the show, these plump dumplings bring a soft, pillowy bite and a hint of sweetness from the dough.
Shredded Cheddar Cheese: Melts into creamy, gooey layers and adds that classic sharpness everyone loves.
Smoked Polska Kielbasa: Brings hearty, robust, and smoky notes to every forkful—don’t be shy, slice them generously!
Salt and Pepper: A simple seasoning duo that ties all the flavors together; sprinkle to taste so each ingredient shines.
Cream Cheese (softened): Blends into the broth for an ultra-smooth, rich sauce you’ll want to slurp with a spoon.
Sliced Green Onions (for serving): The optional finishing touch for fresh flavor and a pop of green on top.

How to Make Crock Pot Pierogi and Kielbasa Casserole

Step 1: Combine the Main Ingredients

Start by adding three cups of chicken broth, the frozen pierogies, half the shredded cheddar cheese, and sliced smoked kielbasa right into your 4-6 quart crock pot. Give everything a gentle stir to get the flavors mingling before you set it to cook. The pierogies will soak up that savory broth, while the cheese gradually melts into the mix, creating little pockets of happiness. Cook on high for 3–4 hours, or let it go low and slow for 6 hours—totally hands-off!

Step 2: Create the Creamy Sauce

About half an hour before you’re ready to serve the Crock Pot Pierogi and Kielbasa Casserole, it’s time to build the creamy sauce. Heat up the cream cheese with the remaining cup of chicken broth in the microwave or on the stovetop until it’s just warm. Whisk this mixture until you get a silky, lump-free sauce—don’t rush this step, as it’s the key to dreamy, indulgent texture.

Step 3: Bring It All Together

Pour your warm, creamy sauce straight into the crock pot. Stir gently to coat every pierogi and slice of kielbasa. Sprinkle the rest of the cheddar cheese on top for a glorious, melty finish, and cover the crock pot again. Let it cook on low for another 30 minutes, allowing all the goodness to meld together. When it’s done, the casserole will be bubbling and perfectly cheesy, just begging to be scooped and served.

Garnishes

Once your casserole is fresh and hot from the crock pot, sprinkle it generously with sliced green onions—they add a gentle crunch and a subtle bite of freshness. Chopped parsley or a sprinkle of paprika works beautifully too if you like a little more color. These finishing touches effortlessly elevate every serving, making it feel extra special.

Side Dishes

The richness of Crock Pot Pierogi and Kielbasa Casserole shines brightest with simple sides. Think crisp green salads, steamed broccoli, or even tangy sauerkraut for a lovely contrast. Buttery peas or roasted carrots are also great—mild enough not to compete, but flavorful enough to round out your plate.

Creative Ways to Present

Treat this casserole as a celebratory potluck star by assembling it in individual ramekins or oven-proof bowls. For a cozy, rustic look, serve it family-style in the crock pot, letting everyone help themselves. You can even transform leftovers into pierogi sliders: tuck a scoop into a soft bun with a little extra cheese and green onion for an unexpected twist!

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any remaining Crock Pot Pierogi and Kielbasa Casserole to airtight containers and refrigerate. It will keep well for up to 3 days. The flavors continue to develop, making leftovers extra tasty—if you even have any left!

Freezing

This casserole is freezer-friendly: portion cooled leftovers into freezer-safe containers, removing as much air as possible. Freeze for up to two months. When you’re ready to enjoy them again, allow portions to thaw overnight in the fridge for best texture and flavor.

Reheating

To reheat, simply microwave individual portions until piping hot, stirring halfway through. Or, for bigger batches, rewarm gently in the oven at 325°F, covered, until everything is bubbling and hot. If the sauce thickens up, just add a splash of broth or milk to loosen.

FAQs

Can I use homemade pierogies instead of frozen?

Absolutely! Homemade pierogies will work beautifully—just make sure they’re uncooked or partially cooked, and handle them gently when stirring so they don’t fall apart.

Is there a way to make this Crock Pot Pierogi and Kielbasa Casserole vegetarian?

Yes, swap the kielbasa for a plant-based sausage and use vegetable broth in place of chicken broth. Opt for cheese pierogies or potato-onion for a meat-free, satisfying alternative.

Can I add vegetables to the casserole?

You sure can! Thinly sliced onions, peppers, or thawed frozen peas work well and add some freshness and extra color to your casserole. Just stir them in at the beginning with the pierogies and kielbasa.

What’s the best way to prevent the pierogies from getting too soft?

Avoid overcooking—stay close to the 3–4 hours on high or 6 hours on low. If your crock pot runs hot, check for doneness a little early. Frozen pierogies hold their shape best for this Crock Pot Pierogi and Kielbasa Casserole.

Can this casserole be prepped ahead for busy nights?

Definitely! You can assemble the ingredients (except for the cream cheese mixture and extra cheese) the night before and refrigerate. In the morning, start the slow cooker and finish with the creamy sauce as directed for a fast weeknight win.
