- 2 cups shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 medium onion, finely chopped
- 2 cloves garlic, minced

- 1 tablespoon olive oil

- 1 cup sour cream
- ½ cup milk
- ½ teaspoon paprika
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- Salt to taste
- ½ teaspoon dried parsley or Italian seasoning
Optional Toppings
- 2 tablespoons chopped fresh parsley
- 2 tablespoons sliced green onions
- ¼ cup grated Parmesan cheese

Ingredient Notes: You can use kielbasa, beef smoked sausage, or another fully cooked smoked sausage you enjoy. Frozen pierogies can generally be added directly to the casserole, although the baking time may vary slightly depending on their size and the package instructions.
Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9-by-13-inch baking dish with butter or cooking spray. This helps prevent sticking and makes serving easier.
Step 2: Prepare the Smoked Sausage
Slice the smoked sausage into evenly sized rounds.
Heat the olive oil in a large skillet over medium heat. Add the sausage slices and cook for approximately 4–6 minutes, turning occasionally, until lightly browned.
Add the chopped onion and cook for another 3–4 minutes until softened. Stir in the minced garlic and cook for about 30 seconds, just until fragrant.
Remove the skillet from the heat.
Step 3: Make the Creamy Sauce
In a large mixing bowl, combine the condensed cream of mushroom soup, sour cream, and milk.
Add the paprika, garlic powder, onion powder, black pepper, parsley, and salt to taste.
Whisk everything together until the mixture is smooth and creamy.
If you prefer a thinner sauce, add another tablespoon or two of milk. The sauce should be pourable but thick enough to coat the pierogies.
Step 4: Add the Pierogies
Arrange the frozen pierogies in the prepared baking dish in a mostly even layer.
Spread the browned sausage, onions, and garlic over the pierogies.
Pour the creamy sauce over everything, making sure the pierogies are well coated. Gently stir or shift the ingredients with a spoon to distribute the sauce without breaking the dumplings.
Step 5: Add the Cheese
Sprinkle the shredded cheddar cheese evenly over the casserole.
Add the mozzarella on top for extra creaminess and a delicious melted-cheese texture.
If desired, finish with a light sprinkling of Parmesan cheese for additional savory flavor.
Step 6: Bake the Casserole
Cover the baking dish tightly with aluminum foil and bake for 25 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the sauce is bubbling around the edges and the cheese is melted and lightly golden.
The pierogies should be heated through and tender. If necessary, bake for a few additional minutes, checking that the center reaches a safe serving temperature.
Step 7: Let It Rest
Remove the casserole from the oven and let it rest for approximately 5–10 minutes before serving.
This short resting period allows the sauce to settle and makes the casserole easier to portion.
Sprinkle with fresh parsley or sliced green onions for a fresh finish.
Step 8: Serve and Enjoy
Serve the casserole warm while the cheese is still creamy and melted.
Pair it with a crisp green salad, steamed vegetables, roasted broccoli, or green beans to balance the richness of the dish.
Every serving combines tender pierogies, smoky sausage, creamy sauce, and melted cheese for a satisfying homemade meal.
Preparation Methods
Method 1: The Easy Oven-Baked Method
The oven-baked method is the simplest way to prepare this casserole. Layer the frozen pierogies, browned sausage, creamy sauce, and shredded cheese in a baking dish, then bake until hot and bubbling.
Covering the dish initially helps the pierogies heat through without the cheese browning too quickly. Removing the foil near the end creates a golden, appetizing topping.
Method 2: The Extra-Cheesy Method
For an even richer casserole, mix half of the cheddar cheese directly into the creamy sauce before pouring it over the pierogies.
Reserve the remaining cheddar and mozzarella for the topping. This creates a creamy cheese sauce throughout the casserole and a melted layer on top.
You can also add a small amount of cream cheese to the sauce for a thicker texture.
Method 3: The Skillet-to-Oven Method
If you want to reduce the number of dishes, brown the sausage, onion, and garlic in an oven-safe skillet.
Stir in the sauce ingredients, add the pierogies, and sprinkle the cheese on top. Transfer the skillet to the oven and bake until everything is heated through.
Make sure the skillet is oven-safe before using this method.
Method 4: The Vegetable-Loaded Method
For extra color and variety, add sliced bell peppers, sautéed mushrooms, spinach, or small broccoli florets.
Cook watery vegetables before adding them so they do not release too much moisture into the casserole. Adjust the seasoning as needed.
The History of Pierogies
Pierogies are closely associated with Polish cuisine and are also enjoyed throughout Central and Eastern Europe. These dumplings have a long culinary tradition, with fillings that vary from region to region and household to household.
Traditional pierogies are made from dough filled with ingredients such as potatoes, farmer’s cheese, sauerkraut, mushrooms, meat, or fruit. They are commonly boiled and may then be pan-fried with butter and onions.
Potato-and-cheese pierogies are especially popular as a hearty, savory meal. In Polish-American communities, pierogies became a familiar comfort food served at family dinners, festivals, church gatherings, and holiday celebrations.
Smoked sausage, including kielbasa, is another food with strong roots in Polish culinary traditions. Combining pierogies and smoked sausage brings together two familiar ingredients in one satisfying dish.
The casserole version is a modern, convenient interpretation rather than a single traditional Polish recipe. It reflects the way home cooks adapt beloved foods to busy schedules by combining them with creamy sauces and cheese in one baking dish.
Today, pierogi casseroles are popular among families who appreciate easy preparation, generous portions, and familiar flavors.

Tips for the Best Pierogi Casserole
Use Plenty of Sauce
Frozen pierogies need enough moisture to heat through without becoming dry. Spread the sauce evenly and ensure the dumplings are coated.
Brown the Sausage First
Browning the sausage develops a deeper savory flavor and adds appealing color to the finished dish.
Choose Cheese That Melts Well
Cheddar gives the casserole a pronounced cheesy flavor, while mozzarella contributes a softer, stretchy texture. Freshly shredded cheese often melts more smoothly than some pre-shredded varieties.
Avoid Overbaking
Bake until the center is hot and the cheese is melted. Excessive baking can make the edges dry or cause the sauce to thicken too much.
Adjust the Seasoning Carefully
Smoked sausage, condensed soup, and cheese may already contain plenty of salt. Taste the sauce before adding extra salt.
Allow Time to Rest
Resting for 5–10 minutes after baking helps the sauce thicken slightly, making the casserole easier to serve.
Serving Suggestions
This casserole is rich and savory, so fresh or lightly seasoned side dishes pair especially well with it.
- Fresh garden salad: Lettuce, tomatoes, cucumber, and a light vinaigrette add freshness.
- Roasted broccoli: Provides color, texture, and a mild earthy flavor.
- Steamed green beans: A simple vegetable side that complements the creamy sauce.
- Roasted carrots: Add a touch of natural sweetness.
- Cucumber salad: A refreshing side that contrasts with the richness of the cheese.
- Crusty bread: Useful for enjoying any remaining creamy sauce.
- Pickles or sauerkraut: Their tangy flavor pairs nicely with smoked sausage and cheese.
For a casual family dinner, serve a generous spoonful of casserole with a green vegetable and a simple salad.
Variations to Try
Spicy Smoked Sausage Casserole
Use spicy smoked sausage and add crushed red pepper flakes or a little hot sauce to the creamy mixture.
Bacon and Pierogi Casserole
Add cooked, crumbled bacon to the sausage mixture for an extra smoky flavor. Because bacon is salty, taste before adding more salt.
Mushroom and Cheese Pierogi Casserole
Sauté sliced mushrooms with the onion and garlic before assembling the casserole. Mushrooms add a savory, earthy flavor.
Broccoli Cheddar Pierogi Casserole
Add lightly steamed broccoli florets and use extra cheddar cheese for a vegetable-filled variation.
Lighter Pierogi Casserole
Use a reduced-fat sour cream, a lower-sodium condensed soup, and a smaller amount of cheese. Add extra vegetables to increase the volume without relying entirely on rich ingredients.
Homemade Cream Sauce Version
Replace the condensed soup with a simple sauce made from butter, flour, milk, and seasonings. Cook until thickened, then stir in a little cheese if desired.
Storage Instructions
Refrigeration
Allow leftover casserole to cool slightly, then transfer it to shallow, airtight containers. Refrigerate within two hours of cooking.
Store leftovers in the refrigerator for 3–4 days.
Reheating
Reheat individual portions in the microwave until steaming hot throughout, stirring or rotating when needed.
For larger portions, cover the casserole with foil and reheat in an oven at 350°F (175°C) until the center is hot. Add a splash of milk if the sauce has thickened too much.
Leftovers should reach 165°F (74°C) when reheated.
Freezing
For best quality, freeze the fully cooked casserole in airtight, freezer-safe containers for up to 2–3 months. The texture of the sour-cream-based sauce may change slightly after thawing.
Thaw in the refrigerator before reheating, and make sure the casserole is heated thoroughly. Avoid repeatedly cooling and reheating the same portion.
Frequently Asked Questions
Can I use frozen pierogies without boiling them first?
Yes. Many frozen pierogies can be baked directly in a casserole with sufficient sauce and moisture. Follow the package instructions when available, and check that the center is fully heated and tender before serving.
Can I prepare this casserole ahead of time?
Yes. You can brown the sausage, prepare the sauce, and measure the ingredients in advance. For the best texture, assemble the casserole shortly before baking. If you assemble it and refrigerate it, keep it covered and allow extra baking time as needed.
Which smoked sausage works best?
Kielbasa is an excellent choice, but beef, turkey, or other fully cooked smoked sausages can also work. The flavor and nutritional values will vary.
Can I make this recipe without cream of mushroom soup?
Absolutely. Use cream of chicken soup, another suitable condensed soup, or a homemade white sauce. Check the seasoning because each alternative has a different flavor and salt content.
How do I know when the casserole is ready?
The cheese should be melted, the sauce should bubble around the edges, and the center should be thoroughly hot. If the dish contains frozen ingredients, allow enough time for the center to reach a safe temperature.
Can I make it less rich?
Yes. Reduce the cheese, use a lighter sour cream, choose lower-fat sausage, and serve the casserole with a generous portion of vegetables.
Common Mistakes to Avoid
- Using too little sauce: The pierogies may become dry before they heat through.
- Skipping the sausage browning step: The finished casserole may have less developed flavor.
- Adding too much salt: Smoked sausage, cheese, and condensed soup are often already salty.
- Baking uncovered for the entire cooking time: The top may brown before the center is hot.
- Serving immediately: The sauce may be too loose to portion neatly.
- Overloading the dish: Keep the ingredients in an even layer so they heat consistently.
