5-Ingredient Crockpot Pierogi Casserole With Kielbasa
Frozen pierogi, smoky kielbasa, and a creamy cheese sauce come together in the slow cooker for a dinner that practically cooks itself. This is the meal you make when you want something hearty and comforting with almost no effort.
It tastes like a cross between a dumpling bake and a loaded mac and cheese, but with a rich, savory backbone from the sausage. Ten minutes of prep, and the crockpot does the rest.
Why This Casserole Works on a Weeknight
The frozen pierogi cook right in the sauce, soaking up the creamy broth without turning mushy. You skip the boiling step entirely, so there’s one less pot to wash.
Kielbasa brings a smoky, salty depth that cuts through all the richness. A little sour cream stirred in at the end brightens the whole dish so it feels cozy, not heavy.
Ingredients
- 1 lb frozen potato and cheddar pierogi : no need to thaw them
- 14 oz smoked kielbasa : slice it into half-moons so every spoonful gets a piece
- 1 (10.5 oz) can cream of mushroom soup : cream of chicken works too
- 4 oz cream cheese : full-fat melts into the smoothest sauce
- 1/2 cup low-sodium chicken broth : helps thin the soup enough to coat the pierogi
- 1 cup shredded sharp cheddar cheese : melts on top into a golden cap
- Salt and black pepper : about 1/2 teaspoon salt and 1/4 teaspoon pepper for the sauce
Variations / Substitutions
- Swap the protein : smoked andouille or turkey kielbasa work, though they will be less rich. For extra heat, use a Cajun sausage.
- Use a different soup : cream of celery or cream of onion both work, just avoid thin broths that won’t thicken properly.
- Dairy-free version : use a plant-based cream cheese and a dairy-free cheddar substitute. The sauce won’t be quite as silky, but it still holds together.
- Add sauerkraut : drain 1 cup and layer it with the kielbasa for a tangy, Eastern European twist.

How to Make Crockpot Pierogi Casserole With Kielbasa
Step 1: Mix the Sauce
In a medium bowl, whisk together the can of cream of mushroom soup, the 1/2 cup chicken broth, 1/2 teaspoon salt, and 1/4 teaspoon black pepper until smooth. The mixture will look a little thin at first, but it thickens as the casserole cooks and the pierogi release their starch.
Don’t skip this step—the sauce needs to be loose enough to pool around the pierogi, not sit on top like a paste. If it seems too thick, add a splash more broth.
Step 2: Layer the Casserole
Give the slow cooker a quick spritz of cooking spray, then spread about a third of the frozen pierogi in an even layer across the bottom. Scatter half the sliced kielbasa over the pierogi, then spoon half the soup mixture on top. Repeat with another third of the pierogi, the rest of the kielbasa, and the remaining soup mixture.
Finish by scattering the cup of cheddar cheese over everything. The layers will look distinct, and the cheese sits right on top where it will melt into a lacy, golden cap during cooking.
Step 3: Slow Cook the Casserole
Cover the slow cooker and cook on LOW for 3 to 4 hours. After about 2½ hours, peek under the lid—the sauce should be bubbling gently around the edges and the pierogi should feel tender when you poke one with a fork.
About 30 minutes before you plan to serve, cube the 4 oz of cream cheese and dot the pieces right across the top of the casserole. Cover again and let the heat melt the cream cheese for 15 to 20 minutes. Then give everything a gentle stir to swirl the cream cheese into the sauce. The casserole turns velvety and rich, with the occasional smoky slice of kielbasa peeking through.
Step 4: Scoop and Serve
Ladle generous spoonfuls into wide bowls while the casserole is still steamy. A scatter of fresh parsley or a crack of black pepper on top makes it look a little more polished, but honestly, it’s perfect straight from the pot. Serve it hot, and don’t be surprised if second helpings happen.
Tips for the Best Slow Cooker Casserole
- Don’t thaw the pierogi.: Putting them in frozen helps them hold their shape and keep a bit of chewiness. Thawed ones can turn gummy.
- Use full-fat cream cheese.: Low-fat versions can break and get grainy when heated. Stir the cream cheese in only after fully melting for the creamiest result.
- Crisp the top under the broiler.: If you miss that oven-baked texture, spoon the finished casserole into a buttered baking dish and broil for 2 to 3 minutes until the cheese bubbles and browns.
- Leftover kielbasa?: Slice and freeze the extras; they’ll keep for a month and can go straight into this recipe from the freezer.
Cook times will vary slightly by slow cooker model, but here’s a quick guide:
| Slow Cooker Setting | Time |
|---|---|
| Low | 3 to 4 hours |
| High | 2 to 2½ hours |
Storing Leftovers
- Refrigerate : Cool the casserole completely, then transfer to an airtight container. It keeps well for up to 4 days.
- Reheating : A short zap in the microwave works, but the stove gives you back some of that saucy texture. Warm individual portions in a skillet over medium-low heat with a splash of broth.
What To Serve With Crockpot Pierogi Casserole With Kielbasa
A bright, crunchy salad is the best counterpoint. Toss arugula or shredded cabbage with a sharp apple cider vinaigrette and a handful of fresh dill. The acidity cuts right through the creamy casserole.
Steamed green peas with a pat of butter also work, adding a little sweetness that plays off the smoky sausage.
Frequently Asked Questions
Can I freeze this casserole?
Yes, it freezes well. Let it cool completely, then portion into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
What size slow cooker do I need?
A 4-quart slow cooker is the minimum for this recipe. Anything smaller will be too tight a fit, and the layers won’t cook evenly.
Can I add vegetables to the casserole?
Absolutely. Toss in a cup of drained sauerkraut, a handful of sautéed onions, or even some thawed frozen spinach. Just make sure any added vegetables are fully cooked or drained first so they don’t release extra water.
What can I use instead of cream cheese?
If you’re out of cream cheese, stir in 1/2 cup of sour cream at the very end, just before serving. The texture will be tangier and slightly looser, but still creamy.
