Ingredients

2 (16 oz) packages frozen potato & cheese pierogies
1 lb kielbasa, sliced into ½-inch rounds
1 medium yellow onion, diced
2 cups shredded cheddar cheese
1 (8 oz) block cream cheese, cubed and softened
1 cup sour cream
1 (10.5 oz) can condensed cream of mushroom soup
½ cup whole milk
½ teaspoon garlic powder
½ teaspoon black pepper
½ teaspoon smoked paprika
2 tablespoons unsalted butter, melted
2 tablespoons fresh chives or parsley, chopped (optional, for garnish)

Directions

Step 1: Prep and Layer

Coat the inside of a 6-quart crockpot with nonstick spray, then scatter the diced onion evenly on the bottom.
Add half of the frozen pierogies over the onions, then scatter half of the sliced kielbasa on top.

Step 2: Make the Creamy Sauce

In a large mixing bowl, whisk together cream of mushroom soup, cream cheese, sour cream, milk, garlic powder, black pepper, and smoked paprika until smooth and well combined.

Step 3: Assemble the Casserole

Spoon half of the creamy sauce mixture over the pierogies and kielbasa in the crockpot, then sprinkle one cup of shredded cheddar over the sauce.
Layer the remaining pierogies and kielbasa, then top with the rest of the creamy sauce and remaining cheddar cheese.
Drizzle the melted butter evenly over the top.

Step 4: Cook

Cover and cook on LOW for 3.5-4 hours, or until the pierogies are tender and the sauce is bubbly and creamy (avoid overcooking so the pierogies hold their shape).

Step 5: Serve

Garnish with chopped chives or parsley, scoop into bowls, and enjoy while hot and creamy!

Notes

Use whole milk and full-fat dairy for the creamiest sauce, though lighter options can work in a pinch.
You don't need to thaw the frozen pierogies before adding them to the crockpot—easy!
If your slow cooker runs hot, check for doneness at 3 hours to prevent overcooking.

Variations

Spicy Kick: Add 1-2 chopped jalapeños or a pinch of crushed red pepper flakes to the sauce.
Veggie Boost: Layer in 1-2 cups of frozen peas, spinach, or bell peppers for extra nutrition and color.
Different Pierogies: Try with frozen sauerkraut, mushroom, or onion pierogies for a tasty twist.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Suggested Pairings & Serving Recommendations

Serve alongside a crisp green salad or roasted vegetables to balance the richness.
Pairs beautifully with crusty bread or a side of steamed green beans.
Try a glass of light lager, wheat beer, or sparkling apple cider as a perfect beverage match.

Pro Tips

Cube the cream cheese and let it come to room temperature for a smoother sauce.
For extra flavor, lightly brown the sliced kielbasa in a skillet before adding to the crockpot.
Let the casserole rest for 10 minutes before serving to allow the sauce to thicken.
