Crockpot Pierogi Casserole Kielbasa

The smell of smoked kielbasa sizzling in a pan takes me back to snowy Sunday afternoons when my neighbor Helen would invite me over for what she called comfort cooking. She taught me that pierogi dont always need to be boiled and pan-fried separately. Sometimes the best things happen when you layer everything together and let time do the work. This casserole became my go-to for those days when I want something hearty but dont want to stand at the stove.

I made this for a Super Bowl party last winter and watched it disappear in fifteen minutes flat. My friend Mike who claims he doesnt like casseroles went back for thirds. The way the smoky kielbasa mingles with the tangy sour cream creates this flavor profile that feels fancy enough for company but cozy enough for a Tuesday night. Now my kids request it anytime temperatures drop below forty degrees.

Ingredients

• 2 packages frozen potato and cheese pierogi: No need to thaw them first, they cook perfectly in the slow cooker and stay fluffy instead of getting gummy
• 1 lb fully cooked kielbasa: The smokiness is essential here and turkey kielbasa works too if you need to lighten it up
• 1 can condensed cream of mushroom soup: Creates the velvety base that brings everything together without much effort
• 1 cup sour cream: Adds that tangy brightness that cuts through all the richness
• 1 cup shredded cheddar cheese: Sharp cheddar gives you the best flavor contrast to the mild pierogi
• 1 medium yellow onion: Thinly sliced so they soften completely and become almost sweet
• 1/2 teaspoon garlic powder: Even this small amount makes a noticeable difference in the overall flavor
• 1/2 teaspoon black pepper: Freshly ground makes all the difference here
• 1/2 teaspoon smoked paprika: Optional but I highly recommend it for that extra layer of smokiness
• 2 tablespoons fresh chives or parsley: Adds a fresh pop of color and flavor right before serving

Instructions

Prep your slow cooker:

Give the insert a light coating of cooking spray or rub it with a little oil so nothing sticks

Build the first layer:

Arrange half the frozen pierogi in an even layer then top with half the kielbasa and half the sliced onions

Mix the sauce:

Whisk together the cream of mushroom soup sour cream garlic powder pepper and paprika until smooth

Add the creamy goodness:

Spread half the sauce mixture over the first layer then sprinkle with half the cheddar cheese

Repeat and cook:

Layer everything again then cover and cook on LOW for 4 hours until hot and bubbly

Finish and serve:

Sprinkle with fresh chives or parsley right before serving

Last Christmas Eve I doubled this recipe and brought it to my inlaws. Everyone stood around the slow cooker lifting the lid and inhaling. My father in law who usually sticks to traditional Polish cooking admitted this might be his new favorite way to eat pierogi. Thats when I knew this recipe had earned its permanent spot in my rotation.

Make It Your Own

Sauerkraut pierogi work surprisingly well here and add a nice tangy contrast. Sometimes I throw in a handful of frozen peas or corn for extra color and nutrition. The recipe is forgiving enough that you can adapt it based on whats in your freezer.

Serving Ideas

A crisp green salad with vinaigrette cuts through all that richness perfectly. Steamed broccoli or roasted green beans add some brightness to the plate. I also love serving it with crusty bread to soak up any extra sauce.

Storage And Reheating

This keeps well in the refrigerator for up to four days. Reheat individual portions in the microwave or warm the whole thing in a 350 degree oven until bubbly. The texture might be even better after the flavors have had time to meld together.

• Freeze portions in airtight containers for up to three months
• Thaw overnight in the refrigerator before reheating
• Add a splash of milk or sour cream when reheating if it seems dry

Theres something deeply satisfying about a meal that takes care of itself while you go about your day. This casserole is comfort food at its finest, simple enough for a weeknight but special enough to share with people you love.

Recipe Q&A

→ Can I vary the pierogi flavor?

Absolutely! While potato and cheese are classic, feel free to experiment with other frozen pierogi varieties like sauerkraut, spinach, or even a meat-filled option for a different twist.

→ Are there alternative sausage options?

Yes, if you prefer a lighter profile or don't eat pork, you can easily swap the kielbasa for turkey sausage or smoked chicken sausage. Ensure they are fully cooked before slicing and adding to the casserole.

→ How can I incorporate more vegetables into this dish?

For added nutrients and flavor, consider stirring in sautéed mushrooms, bell peppers, or a handful of fresh baby spinach during the layering process. They will cook down beautifully in the slow cooker.

→ What are some good serving suggestions?

This hearty casserole pairs wonderfully with a simple side to balance the richness. A crisp green salad with a light vinaigrette, steamed broccoli, or green beans would make excellent accompaniments.

→ Can this dish be prepared in advance?

While it's best enjoyed fresh from the slow cooker, you can assemble the layers the night before and refrigerate. Just add an extra hour to the cooking time if starting from cold. Leftovers also reheat well.
