Ingredients Notes

The beauty of this recipe lies in its simple yet flavorful ingredients. Here’s a closer look at the key components:

Frozen Pierogies: These little dumplings are the star of the dish. Opt for a classic potato and cheese filling for a traditional flavor, or experiment with other varieties like sauerkraut or spinach for a twist.
Kielbasa: The smoky, savory flavor of kielbasa adds depth to the casserole. You can use turkey kielbasa for a lighter option or stick with the classic pork variety for full flavor.
Cream of Mushroom Soup: This creates the base of the creamy sauce. You can substitute cream of chicken soup if you prefer a slightly different taste.
Cheddar Cheese: Shredded cheddar melts beautifully into the sauce, adding a rich, cheesy flavor that ties everything together. Sharp cheddar works best for maximum flavor.
Sour Cream: Adds tanginess and helps create the perfect creamy texture. For a lighter version, you can use plain Greek yogurt.
Onion and Garlic Powder: These simple seasonings enhance the overall flavor without overpowering the dish.

No special equipment is needed, just a reliable crockpot and a mixing spoon to bring everything together!

How To Make Crockpot Pierogi Casserole With Kielbasa

Creating this comforting casserole is a breeze. Let’s break it down step by step:

Prepare the Crockpot
Lightly grease the inside of your crockpot to prevent sticking. This step makes cleanup much easier.
Layer the Ingredients
Start by arranging the frozen pierogies in an even layer at the bottom of the crockpot. Scatter the sliced kielbasa over the top, ensuring the pieces are evenly distributed.
Mix the Sauce
In a mixing bowl, combine the cream of mushroom soup, sour cream, and seasonings (a pinch of onion powder and garlic powder). Stir in half of the shredded cheddar cheese until well blended.
Pour and Top
Pour the creamy mixture over the pierogies and kielbasa, making sure everything is coated. Sprinkle the remaining cheddar cheese over the top for a gooey, cheesy finish.
Cook
Set your crockpot to low and let the casserole cook for 4-5 hours, or on high for 2-3 hours. The cheese should be melted, the sauce bubbling, and the pierogies tender.
Serve and Enjoy
Once ready, give the casserole a gentle stir and serve hot. Garnish with chopped parsley or green onions for a pop of color and extra flavor.

Storage Options

This casserole is just as delicious the next day, making it perfect for leftovers. Here’s how to store and reheat it:

Refrigeration: Transfer any leftovers to an airtight container and store them in the fridge for up to 3 days.
Freezing: For longer storage, place the casserole in a freezer-safe container. It will keep well for up to 2 months. Thaw in the refrigerator overnight before reheating.

To reheat, place the casserole in a microwave-safe dish and heat in 1-minute intervals, stirring in between. Alternatively, you can warm it in the oven at 350°F (175°C) until heated through.

Variations and Substitutions

One of the best things about this recipe is its adaptability. Here are a few ways you can customize it:

Add Vegetables: Stir in steamed broccoli, peas, or sautéed mushrooms for extra nutrition and flavor.
Spice It Up: Add a pinch of red pepper flakes or diced jalapeños to give the casserole a kick.
Swap the Protein: Try smoked sausage, cubed ham, or even shredded rotisserie chicken instead of kielbasa.
Lighter Option: Use light sour cream, reduced-fat cheddar, and turkey kielbasa to make a healthier version.
Herbaceous Touch: Sprinkle fresh dill or thyme on top for a burst of freshness.
