- 1 lb kielbasa or smoked sausage, sliced into ½-inch rounds
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- Salt & black pepper, to taste
Creamy Sauce
- 1 can (10.5 oz) cream of mushroom soup (or cream of chicken)
- 1 cup sour cream
- ½ cup chicken broth
- 1 tsp paprika (optional, but adds great flavor)
- 1 cup shredded cheddar cheese, divided
Optional Garnish
- Fresh chopped parsley, for serving
Step-by-Step Instructions
1. Prep the Ingredients
Slice the kielbasa into rounds.
Finely chop the onion and mince the garlic.
2. Layer Everything in the Crock Pot
Add ingredients in this order:
- Frozen pierogies (even layer)
- Kielbasa slices (spread evenly)
- Chopped onion
- Minced garlic
3. Make the Creamy Sauce
In a medium bowl, whisk together:
- cream of mushroom soup
- sour cream
- chicken broth
- paprika (if using)
- ½ cup shredded cheddar cheese
Stir until smooth.
4. Pour and Mix
Pour the sauce evenly over the pierogies and kielbasa.
Gently stir just enough to coat everything without breaking the pierogies.
5. Slow Cook
Cover and cook on:
- LOW for 3–4 hours
Cook until pierogies are tender and the sauce is hot and bubbly.
6. Add the Cheese Finish
During the last 20–30 minutes, sprinkle the remaining cheddar cheese over the top.
Cover again until melted and gooey.
7. Serve
Spoon into bowls and garnish with parsley if desired.
Serve hot and creamy while the cheese is still melty.

Storage
