Understanding this Recipe

Pierogi are dumplings that have their origins in Eastern Europe, particularly Poland, where they are cherished as a staple comfort food. Traditionally, they are filled with a variety of ingredients, the most common being mashed potatoes, cheese, or sauerkraut. In this Crockpot version, we’ve taken the classic flavors and combined them with kielbasa for an easy, one-pot meal that’s rich in taste and texture. The slow cooker offers a distinct advantage for this casserole: the low and slow cooking method deeply melds the flavors together, resulting in a comforting, hearty dish that’s simple to whip up during busy weeknights.

Casseroles typically shine at potlucks or family gatherings, where they can be prepared ahead of time and served to a crowd. This Crockpot Pierogi Casserole is perfect for such occasions due to its ease of prep and the convenience of cooking in a single pot. No need to fuss over multiple sides or complicated preparations; just set it and forget it! Plus, its cheesy, savory profile is sure to leave all your guests smiling and satisfied. Fun fact: This dish is sometimes referred to as “lazy pierogi,” as it takes all the work out of filling and boiling the dumplings!

Your Guide to Making Crockpot Pierogi Casserole with Kielbasa at Home

Making this revoltingly good casserole is easier than you might think! Grab your slow cooker and let’s get started. This recipe requires just a few simple steps that will have you enjoying a delicious meal on the table in no time.

Ingredients

Frozen Pierogi (24 oz): Use your favorite type—potato, cheese, or even sauerkraut-filled for a zing. Frozen options save time.
Kielbasa (12 oz): A hearty, smoked sausage that’s rich in flavor. You can also use turkey or chicken kielbasa for a lighter option.
Cream of Mushroom Soup (10.5 oz): This adds a creamy base and depth of flavor. You can substitute with homemade cream sauce or a different soup if desired.
Shredded Cheddar Cheese (2 cups): Provides creaminess and pulls everything together. Consider using a sharp cheddar for more flavor.
Onion (1 medium, chopped): Adding a subtle sweetness when cooked, which complements the savory sausage beautifully.
Garlic Powder (1 tsp): For additional flavor—fresh garlic works too if you prefer.
Salt and Pepper: Season to taste.

Directions

Prepare your slow cooker: Lightly grease your Crockpot to prevent sticking. This will also help during clean-up later. A touch of cooking spray or olive oil works wonders!
Layer the ingredients: Begin by placing half of the frozen pierogi at the bottom of the slow cooker. Then add half of the chopped kielbasa, half of the cream of mushroom soup, and half of the shredded cheese.
Season: Sprinkle salt, pepper, and garlic powder on top of the layered ingredients. The seasoning is important for getting the flavors just right.
Repeat the layers: Add the remaining pierogi, followed by the rest of the kielbasa, soup, and cheese. Finish with a final sprinkle of seasoning to ensure everything is evenly flavored.
Cook: Cover your slow cooker and cook on low for 6-8 hours or on high for 3-4 hours. The casserole is done when it’s bubbly and the cheese is melty.
Check on it: About halfway through cooking, remove the lid and stir gently to mix the layers, being careful not to break the pierogi.
Serve: Once cooked, let it sit for 10-15 minutes before serving. This allows the casserole to firm up slightly and makes for easier servings.

What to Serve With Crockpot Pierogi Casserole with Kielbasa

This hearty casserole is satisfying on its own, but pairing it with the right sides can elevate your meal! Consider serving it with a simple side salad to add freshness and crunch. A light vinaigrette works well to cut through the richness of the casserole.

Steamed Green Beans: Their crispness offers a perfect contrast to the creamy texture of the casserole.
Sauerkraut: A traditional German side that provides acidity and brightness, balancing the dish very well.
Garlic Bread: Perfect for soaking up any leftover creamy sauce, garlic bread adds flavor and a satisfying crunch.
Pickles: Serving a few tangy pickles on the side enhances the meal with a refreshing tang that complements the richness.

Pro Tips for the Best Crockpot Pierogi Casserole

While this recipe is approachable, there are a few tips to ensure your dish comes out perfectly every time:

Ingredient swaps or upgrades: Feel free to swap the kielbasa for chicken or vegan sausages for a lighter meal. You can also try different flavored pierogis to enhance the dish.
Spice adjustments: If you prefer heat, add a pinch of red pepper flakes or diced jalapeños for an extra kick.
Equipment advice: A 6-quart slow cooker is ideal for this recipe, allowing enough space for the layers to cook evenly.
Storage tips: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently in the microwave or on the stovetop.
Mistakes to avoid: Make sure to stir the layers halfway through cooking to avoid them sticking together, and always ensure your pierogi are fully thawed before beginning for even cooking.

Variations & Add-Ins

Now, let’s chat about how you can make this casserole fit your family’s tastes even more! Here are a few variations to consider:

Vegetarian Version: Substitute kielbasa with sautéed mushrooms or roasted vegetables. Add a bit of vegetable broth and extra seasonings to maintain flavor.
Cheesy Broccoli Addition: Add 2 cups of fresh or frozen broccoli florets to boost the nutrition factor and add some vibrant color to the casserole.
Spicy Kielbasa: For a smoky twist, opt for spicy chorizo or Andouille sausage which brings heat and depth to the flavor profile.
Herb Infusion: Fresh herbs like dill or parsley can be tossed in before serving, adding a fresh burst of flavor that enhances the casserole.

Kid-Friendly Version

If you’re cooking for picky eaters, consider these modifications: Replace the kielbasa with diced chicken or turkey for a milder profile. To make it even more appealing, use only cheese-filled pierogi and incorporate a dash of ranch seasoning to provide familiarity. Cutting the casserole into fun shapes before serving can also make the meal more engaging for little ones. Don’t shy away from letting kids sprinkle herbs or cheese on their individual servings—they’ll feel like little chefs!

Storing and Reheating Tips

For leftover Crockpot Pierogi Casserole, it’s essential to store it correctly to retain its delightful flavors and textures. First, allow the casserole to cool to room temperature before transferring it to an airtight container. Refrigerate and enjoy your leftovers within three days for optimal freshness. If you need to store it for longer, consider portioning it into freezer-safe bags or containers. This allows you to defrost only what you need.

When it comes to reheating, you have several options! If you’re using a microwave, heat individual portions for about 2-3 minutes, stirring halfway through. For an oven, bake at 350°F (175°C) for about 20-25 minutes, until warmed through. If you’re short on time, an air fryer can crisp the top nicely—simply reheat at 350°F (175°C) for 10-15 minutes. Avoid freezing the dish with the cheese topping if possible, as it might become rubbery upon reheating and affect texture.
