Using frozen pierogies makes this recipe incredibly convenient while still delivering authentic comfort food flavor.
Ingredients
Main Ingredients:
- 1 (32-ounce) bag frozen potato and cheese pierogies
- 1 pound kielbasa sausage, sliced into ¼-inch rounds
- 1 small onion, finely diced
- 2 cups shredded sharp cheddar cheese
- 1 (8-ounce) block cream cheese, cubed
- 1 cup chicken broth
- 1 cup heavy cream (or half-and-half)
- 2 tablespoons butter, sliced
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- Salt to taste
Optional Add-Ins for Extra Flavor
- 1 cup sliced mushrooms
- ½ teaspoon smoked paprika
- 1 cup frozen peas
- ½ teaspoon dried thyme
- Crumbled cooked bacon
- Chopped fresh parsley for garnish
- Sour cream for serving
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Slice the kielbasa into even rounds to ensure even cooking. Dice the onion and cube the cream cheese for faster melting.
There’s no need to thaw the pierogies—add them straight from the freezer.
Step 2: Layer the Slow Cooker
Lightly spray the inside of your crock pot with nonstick cooking spray.
Start by placing half of the frozen pierogies on the bottom.
Add half of the sliced kielbasa and half of the diced onion over the pierogies.
Repeat the layers with the remaining pierogies, sausage, and onion.
Layering helps distribute flavor evenly throughout the casserole.
Step 3: Make the Creamy Sauce
In a mixing bowl, whisk together:
- Chicken broth
- Heavy cream
- Garlic powder
- Black pepper
Pour this mixture evenly over the layered ingredients in the slow cooker.
Place cubes of cream cheese and slices of butter evenly over the top.
As it cooks, these will melt into a rich, creamy sauce.
Step 4: Slow Cook
Cover and cook on:
- LOW for 4–5 hours
or - HIGH for 2–3 hours
Avoid lifting the lid frequently, as this releases heat and can extend cooking time.
The pierogies should be tender and fully heated through, and the cream cheese should be melted into the sauce.
Step 5: Add the Cheddar Cheese
About 20–30 minutes before serving, sprinkle the shredded cheddar cheese evenly over the top.
Cover again and allow the cheese to melt completely.
Before serving, gently stir the casserole to evenly distribute the creamy sauce without breaking the pierogies.
Serving Suggestions
This Crock Pot Pierogi Casserole is filling enough to stand alone, but it pairs beautifully with:
- A fresh green salad
- Steamed broccoli or green beans
- Roasted Brussels sprouts
- Sauerkraut for a traditional touch
- Crusty bread or dinner rolls
For extra richness, serve with a dollop of sour cream and a sprinkle of chopped parsley.
Tips for the Best Results
Use smoked kielbasa for deeper flavor
Do not overcook, as pierogies can become overly soft
