- 1 (10.5-ounce) can condensed cream of chicken soup
- 1 cup sour cream

- 1/2 cup butter, melted
- 1/2 teaspoon black pepper
- 1/4 teaspoon garlic powder
- 1/2 cup shredded sharp cheddar cheese (for topping)
- 1/4 cup chopped green onions (for garnish, optional)
Step-by-Step Instructions
- In a large bowl, whisk together the cream of chicken soup, sour cream, milk, melted butter, black pepper, and garlic powder until the sauce is smooth and well combined. This creamy mixture forms the base of your casserole.
- Lightly grease the interior of your slow cooker insert to prevent sticking.
- Pour about one-third of the creamy soup mixture into the bottom of the slow cooker and spread it evenly.
- Place half of the frozen pierogies over the sauce layer.
- Layer half of the sliced kielbasa evenly over the pierogies.
- Pour another one-third of the soup mixture over the kielbasa layer.
- Repeat the layers: remaining pierogies, remaining kielbasa, and top with the remaining soup mixture, ensuring everything is mostly covered.
- Cover the slow cooker and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours, or until the pierogies are tender and slightly puffed.
- During the last 15 minutes of cooking, remove the lid and sprinkle the shredded cheddar cheese evenly over the top. Replace the lid until the cheese is melted and bubbly.
- Carefully stir the casserole to distribute the cheese and sauce throughout before serving. Garnish with fresh green onions, if desired.
Expert Tips / Pro Tips
For the best results when making Crockpot Pierogi Casserole with Kielbasa, keep these tips in mind: Do not thaw the pierogies; cooking them directly from frozen helps them maintain their shape better during the slow cooking process. If your sauce seems too thick when serving, stir in a splash more milk or sour cream to achieve your desired consistency. Avoid stirring the casserole too frequently during the cooking process, as this can break down the pierogi dough and turn the dish mushy. Check for doneness by gently poking a pierogi with a fork; it should yield easily.Variations & Substitutions
There are many ways to customize this hearty casserole. You can switch out the smoked sausage for shredded rotisserie chicken or even diced smoked ham for a different flavor profile. If you prefer a tangier flavor, substitute the cream of chicken soup with cream of mushroom soup. For a little kick, add a teaspoon of dried mustard powder or a dash of hot sauce to the mixing liquid. Vegetables like finely diced onions or frozen mixed vegetables (peas and carrots work well) can be stirred in with the kielbasa for added nutrition.Serving Suggestions
This Crockpot Pierogi Casserole with Kielbasa is a complete meal on its own, but it pairs wonderfully with bright, fresh side dishes to cut through the richness. Consider serving it alongside a crisp, simple green salad tossed with a light vinaigrette. Steamed green beans or a side of tangy coleslaw also make excellent accompaniments. For an authentic pairing, serve extra sour cream on the side for dolloping.Storage, Freezing & Reheating
To store leftovers, place the cooled casserole in an airtight container. It will keep well in the refrigerator for up to 4 days. To freeze, portion the casserole into freezer-safe containers. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating. To reheat, microwave individual portions until heated through, or reheat the entire casserole in a 350°F oven, covered with foil, until hot (about 20-30 minutes), adding a splash of milk if it seems dry.Nutrition Information

FAQ
Can I use fresh rather than frozen pierogies?
Yes, you can use fresh pierogies, but you should reduce the cooking time significantly, especially on HIGH heat, as they require less time to become tender.
What kind of sausage works best in this recipe?
Smoked Polish kielbasa offers the most traditional and savory flavor, but any good quality smoked sausage will work excellently in this Crockpot Pierogi Casserole with Kielbasa.
Do I need to pre-cook the kielbasa before adding it to the slow cooker?
No, pre-cooking is not necessary. The sausage will cook and flavor the sauce as the casserole simmers in the slow cooker.
Can I skip the sour cream?
While the sour cream provides essential tanginess and creaminess, if you must omit it, you can substitute it with an equal amount of plain Greek yogurt for a slightly healthier alternative, though the texture will be slightly different.
