Ingredients
Scale
Main Ingredients
- 2 (16 oz) packages frozen potato and cheese pierogi
- 1 lb kielbasa, sliced into ½-inch rounds
- 1 medium yellow onion, thinly sliced
- 2 cups shredded cheddar cheese
Sauce Ingredients
- 1 (10.5 oz) can condensed cream of mushroom soup
- 1 cup sour cream
- ½ cup milk
- ½ tsp garlic powder
- ¼ tsp black pepper
Garnish
- 2 tbsp chopped fresh chives or parsley
Instructions
- Prepare the Slow Cooker: Lightly grease the insert of a 6-quart slow cooker with cooking spray or butter to prevent sticking and make cleanup easier.
- Create First Layer: Arrange half of the frozen pierogi in an even layer on the bottom of the slow cooker. Then evenly layer half of the sliced kielbasa and half of the thinly sliced onions on top. Sprinkle with 1 cup of shredded cheddar cheese.
- Build Second Layer: Repeat the layering process using the remaining pierogi, kielbasa, onions, and then sprinkle with the remaining 1 cup of cheddar cheese on top.
- Prepare Creamy Sauce: In a medium mixing bowl, whisk together the condensed cream of mushroom soup, sour cream, milk, garlic powder, and black pepper until the mixture is smooth and well combined.
- Add Sauce and Cook: Pour the creamy sauce evenly over the layered ingredients in the slow cooker. Cover with the lid and cook on LOW for 4 hours, until the casserole is heated through, bubbly, and the cheese has fully melted.
- Garnish and Serve: Just before serving, sprinkle the casserole with chopped fresh chives or parsley for a fresh burst of flavor and color. Serve warm.
Notes
- Do not thaw the pierogi before layering; add them frozen to prevent overcooking and maintain texture.
- Use a 6-quart slow cooker for best results to ensure even cooking without overflowing.
- Feel free to substitute cheddar with your favorite melting cheese such as mozzarella or Monterey Jack.
- For a spicier kick, add a pinch of red pepper flakes to the creamy sauce.
- This casserole can be prepared a few hours ahead and kept warm on the slow cooker’s ‘keep warm’ setting before serving.
