- 1 cup of shredded cheddar cheese: Adds a rich, cheesy flavor to the casserole.

Substitutions and Variations
This Crockpot Pierogi Casserole with Kielbasa recipe is very flexible and can be easily adapted to suit your preferences. If you prefer a different type of sausage, you can substitute the kielbasa with smoked sausage, andouille, or even a spicy chorizo. For a vegetarian version, skip the kielbasa and add sautéed mushrooms, spinach, or other vegetables to the casserole. If you’re not a fan of cream of mushroom soup, you can use cream of chicken or cream of celery soup instead. You can also mix up the cheese by using a blend of different cheeses, such as mozzarella, Monterey Jack, or Gouda, for added flavor. For a spicier kick, consider adding a pinch of red pepper flakes or a few dashes of hot sauce to the cheese sauce.
Step-by-Step Cooking Instructions

Making Crockpot Pierogi Casserole with Kielbasa is simple and requires minimal prep work. Here’s how to prepare it:
- Prepare the Kielbasa and Onion: Start by slicing the kielbasa into ¼-inch thick rounds and finely chopping the onion. If you prefer, you can lightly brown the kielbasa in a skillet before adding it to the crockpot for extra flavor, but this step is optional.
- Make the Cheese Sauce: In a medium bowl, combine the shredded cheddar cheese, sour cream, cream of mushroom soup, milk, and minced garlic. Stir until the mixture is well combined and smooth. Season the sauce with salt and pepper to taste.
- Layer the Ingredients in the Crockpot: Lightly grease the inside of your crockpot with cooking spray. Place one package of frozen pierogies at the bottom of the crockpot. Layer half of the sliced kielbasa and chopped onion over the pierogies. Pour half of the cheese sauce over the kielbasa and pierogies. Repeat the layers with the remaining pierogies, kielbasa, onion, and cheese sauce.
- Cook the Casserole: Cover the crockpot with the lid and cook on low for 4-5 hours or on high for 2-3 hours. The casserole is done when the pierogies are tender, the kielbasa is heated through, and the cheese sauce is bubbly and creamy.
- Garnish and Serve: Once the casserole is cooked, give it a gentle stir to ensure the sauce is evenly distributed. Garnish with chopped fresh parsley if desired. Serve hot, straight from the crockpot.
Common Mistakes to Avoid
To ensure your Crockpot Pierogi Casserole with Kielbasa turns out perfectly, avoid these common mistakes. One mistake is overcooking the casserole. Pierogies can become too soft and lose their texture if cooked for too long. Be sure to check the casserole after the minimum recommended cooking time to prevent overcooking. Another mistake is not properly mixing the cheese sauce. Make sure the sauce is well combined and smooth before layering it in the crockpot to ensure even distribution of flavor. Finally, be cautious with seasoning—both the kielbasa and cheese can be quite salty, so taste the sauce before adding more salt.
Serving and Presentation Tips
This dish is comforting and satisfying on its own, but with a few thoughtful touches, you can make it even more inviting.
How to Serve Crockpot Pierogi Casserole With Kielbasa
Crockpot Pierogi Casserole with Kielbasa is a hearty meal that can be served as a main dish alongside simple sides. Pair it with a crisp green salad dressed with a light vinaigrette to balance the richness of the casserole. For added vegetables, serve it with steamed broccoli, green beans, or sautéed spinach. If you’re feeding a crowd, you can serve the casserole with crusty bread or dinner rolls to help soak up the creamy sauce. For a special touch, consider serving the casserole in individual bowls or small cast iron skillets for a rustic, homey presentation.
Presentation Ideas for Crockpot Pierogi Casserole With Kielbasa
To elevate the presentation of this comforting casserole, garnish it with a sprinkle of freshly chopped parsley or chives for a pop of color. You can also add a little extra shredded cheese on top and pop the crockpot insert under the broiler for a few minutes to create a golden, bubbly cheese crust before serving (just make sure your crockpot insert is oven-safe!). If you’re serving this dish for a special occasion, consider plating it with a side of roasted vegetables or a vibrant salad to add color and contrast to the meal.
Recipe Tips for Crockpot Pierogi Casserole With Kielbasa
To make the most of your Crockpot Pierogi Casserole with Kielbasa, keep these tips in mind. First, for extra flavor, consider sautéing the onions and garlic before adding them to the crockpot. This step isn’t necessary, but it can enhance the depth of flavor in the dish. If you prefer a thicker sauce, reduce the amount of milk slightly or add an extra handful of cheese to the sauce. If you find the sauce too thick, you can thin it out with a splash of chicken broth or more milk. Lastly, if you’re short on time, you can prep the ingredients the night before and store them in the refrigerator—simply assemble the casserole in the morning and set the crockpot to cook.
