Ingredients You’ll Need

Getting started with this casserole is a breeze since the ingredients list is straightforward yet purposeful. Each element plays a special role in balancing the dish’s heartiness, creaminess, and just the right hint of savory.

• Frozen potato and cheese pierogi (16 ounces): The star base providing comforting, pillowy bites packed with melty cheese and potatoes.
• Kielbasa sausage (1 pound): Adds smoky, savory flavor and a bit of meatiness, sliced into perfect rounds for even cooking.
• Medium onion (1, chopped): Brings a subtle sweetness that caramelizes gently during slow cooking.
• Sour cream (1 cup): Creams the casserole with tang and lush texture that melds everything together.
• Cream of mushroom soup (10.5 ounces): Adds depth and an umami boost to the creamy mixture.
• Shredded cheddar cheese (1 cup): Melts into ooey-gooey goodness that makes every bite irresistible.
• Milk (1/4 cup): Helps thin the sauce just enough for perfect coat and bubble.
• Butter (1 tablespoon): Used to grease the crockpot so nothing sticks, and it adds a subtle rich note.
• Salt and pepper (to taste): Essential seasonings to brighten and balance all the flavors.
• Fresh parsley (chopped, for garnish): Adds a pop of fresh color and light herbal notes to finish the dish beautifully.

How to Make Crockpot Pierogi Casserole with Kielbasa Recipe

Step 1: Prepare the Crockpot

Start by greasing the inside of your crockpot with the tablespoon of butter. This little step ensures nothing sticks as the casserole cooks, keeping the flavors intact and easy cleanup afterward.

Step 2: Layer Kielbasa and Onion

Place the sliced kielbasa sausage and chopped onion into the crockpot. These ingredients create a flavorful foundation as they slowly mingle together, infusing the dish with a smoky, slightly sweet aroma.

Step 3: Add the Pierogi

Next, lay the frozen potato and cheese pierogi on top of the kielbasa and onion mixture. No need to thaw them; they’ll thaw and cook perfectly right in the crockpot, soaking up all the delicious flavors below.

Step 4: Make the Creamy Sauce

In a bowl, combine sour cream, cream of mushroom soup, shredded cheddar cheese, and milk. Stir until smooth and creamy—the sauce that will bring all those layers together in a luscious, cheesy blanket.

Step 5: Pour the Sauce

Evenly pour the creamy mixture over the pierogi, kielbasa, and onions in the crockpot. Make sure every bit gets coated to infuse richness throughout the casserole.

Step 6: Season

Sprinkle salt and pepper to taste, adjusting to your preference. This elevates the flavors, ensuring the dish sings with every bite.

Step 7: Cook Low and Slow

Cover the crockpot with the lid and cook on low for 4 to 5 hours or on high for 2 to 3 hours. During this time, the pierogi become tender, the cheese melts perfectly, and the sauce bubbles enticingly.

Step 8: Garnish and Serve

Once cooking is complete, sprinkle fresh chopped parsley on top to add a burst of freshness and vibrant color to your savory creation.

Step 9: Enjoy the Comfort

Serve the Crockpot Pierogi Casserole with Kielbasa Recipe hot and savor the delightful medley of tender pierogi, smoky sausage, and creamy cheese sauce in every mouthful.

Garnishes

Beyond the fresh parsley, consider topping your casserole with a dollop of sour cream or a sprinkle of crispy fried onions to add texture and tang that elevate the dish’s cozy vibe even more.

Side Dishes

This casserole pairs wonderfully with a crisp green salad dressed in light vinaigrette to balance its richness. Roasted vegetables or steamed green beans also make perfect veggie sides without overwhelming the main flavors.

Creative Ways to Present

For a fun twist at gatherings, serve the casserole in individual ramekins or mini crockpots, allowing everyone to enjoy their own bubbling serving. Adding a side of spicy mustard or horseradish sauce can also complement the kielbasa beautifully for those craving a bit of zing.

Make Ahead and Storage

Storing Leftovers

Once cooled, transfer any leftovers into airtight containers and keep them in the refrigerator. The casserole stays flavorful and moist for up to 3 days, perfect for quick, comforting meals on busy evenings.

Freezing

You can freeze portions of this Crockpot Pierogi Casserole with Kielbasa Recipe for up to 2 months. Use freezer-safe containers or bags, and thaw overnight in the refrigerator before reheating to keep the texture just right.

Reheating

To reheat, place leftovers in the microwave or oven until warmed through. Adding a splash of milk before reheating helps maintain the creamy sauce’s luscious consistency and prevents it from drying out.

FAQs

Can I use fresh pierogi instead of frozen?

Absolutely! Fresh pierogi will work beautifully and may cook a bit faster, so keep an eye on them during the crockpot process to avoid overcooking.

Is it possible to make this recipe vegetarian?

Yes! Simply omit the kielbasa and perhaps add mushrooms or a hearty vegetable like eggplant or zucchini to keep the casserole full and savory without meat.

Can I prepare this recipe in an oven instead of a crockpot?

Yes, you can assemble everything in a baking dish and bake at 350°F for about 45 minutes until bubbly and golden on top. Cover with foil initially to keep it moist.

What kind of kielbasa works best?

Traditional smoked kielbasa is ideal for its robust flavor, but you can use Polish or any smoked sausage you prefer. Just pick something with a good balance of smokiness and seasoning.

Can I add other cheeses to this recipe?

Definitely! While cheddar provides sharpness, mixing in mozzarella for meltiness or Parmesan for a salty punch makes the casserole even more decadent and flavorful.
